1 Summary
The National Recovery Plan for albatrosses and petrels (2022) provides a national strategy to guide the activities of government, industry, research organisations, and other stakeholders in the protection, conservation and management of listed threatened albatross and petrel species. The plan outlines the research and management actions necessary to stop the decline and support the recovery of the species so that their chances of long-term survival in nature are maximised. The plan also outlines the major benefits to other albatross and petrel species that are not listed as threatened, but will be affected by the implementation of the plan.
Seabirds remain among the world's most threatened bird species. Albatrosses and petrels in particular face an ongoing conservation crisis. Many threatened albatross and petrel species breed and/or forage in Australia's jurisdiction and distribute widely across the world's oceans and remote, offshore islands. These species face a range of threats to their long-term survival on land, particularly habitat degradation and predation by feral species, and at sea, particularly incidental catch during fishing operations. The recovery of threatened albatrosses and petrels relies on an integrated approach involving actions at domestic and international levels. Although Australian breeding and/or foraging populations of albatrosses and petrels, other than the endemic Shy Albatross (Thalassarche cauta), generally represent a small proportion of global populations, these species make a significant contribution to Australia's biodiversity.
The recovery plan recognises that recovery of threatened albatrosses and petrels will take longer than the 10-year life of the current plan due to the long generation lengths and life histories of the species concerned. It further acknowledges that a recovery plan should remain in place for affected species until such time as the conservation status of the species breeding and/or foraging in Australia's jurisdiction has improved to the point where populations are considered secure. The plan aims to provide continuity for recovery actions for these long-lived species, and also recognises that within the five-year timeframe for reviewing progress under a recovery plan there is insufficient time to determine accurately changes affecting the recovery of the species within Australia's jurisdiction. The plan also aims to provide continuity for international advocacy by Australia, particularly through the Agreement on the Conservation of Albatrosses and Petrels, relevant regional fisheries and conservation bodies, and through engaging with range states and international bodies with an interest an expertise in conserving the species.
The long-term vision under this recovery plan is that the populations of albatross and petrel species breeding and/or foraging in Australia's jurisdiction have increased to such a size that the species no longer qualify for listing as threatened under any of the EPBC Act listing criteria.
The objective of the recovery plan is:
To improve the conservation status of albatrosses and petrels so that these species are on a trajectory towards no longer being threatened in Australia's jurisdiction.
The success or otherwise of the recovery plan including the trajectory of species will be measured according to progress on the plan's strategies and overarching actions. The objective will be achieved if within three generations (60 years approx.) there is a measurable and sustained positive population trend (compared to 2021 baseline counts) in the number of mature individuals within the Australian breeding populations of albatross and petrel species within the recovery plan. The recovery plan includes strategies and overarching actions to be applied within Australia's jurisdiction that protect albatross and petrel breeding habitats, address threats to the conservation of the species on land and at sea, generate new knowledge to guide recovery, and increase public awareness. The plan will also assist in the implementation of Australia's international environmental responsibilities, in particular to give effect to obligations under the Agreement on the Conservation of Albatrosses and Petrels and Convention on Biological Diversity, and including engagement with relevant regional conservation and fisheries organisations and arrangements to advance the conservation of albatrosses and petrels.
Strategies have been identified that will be used to measure the effectiveness of the recovery plan and progress towards its objective over the life of the plan.
Ensure ongoing protection of albatross and petrel breeding sites and habitats in Australia's jurisdiction.
2. Improve the understanding of the size, structure and population trends for albatrosses and petrels breeding in Australia's jurisdiction.
3. Improve effectiveness of management measures that reduce land-based threats to albatrosses and petrels breeding in Australia's jurisdiction.
4. Improve effectiveness of management measures that reduce marine-based threats to albatrosses and petrels foraging in Australia's jurisdiction.
5. Improve understanding of generalised threats to albatrosses and petrels breeding and foraging within Australia's jurisdiction.
6. Improve community awareness of the conservation of albatrosses and petrels.
7. Achieve substantial progress towards global conservation of albatrosses and petrels in international conservation and fishing forums.
This recovery plan is being made jointly by the Australian Government, and the governments of Western Australia, Victoria, Tasmania and Queensland. This joint approach recognises the wide distribution of albatrosses and petrels that breed and forage in Australia's jurisdiction. The approach ensures that complementary actions are taken by the Commonwealth, and by states in areas under their respective control and responsibility. The Australian Government is committed to acting in accordance with the recovery plan and to implementing the plan as it applies to Commonwealth areas.
The recovery plan has been developed with the involvement and cooperation of a broad range of stakeholders, however individual stakeholders have not necessarily committed to undertaking specific actions. The attainment of objectives and the provision of funds may be subject to budgetary and other constraints affecting the parties involved. Proposed actions may be subject to modification over the life of the plan due to changes in knowledge.
2 Introduction
TheEnvironment Protection and Biodiversity Conservation Act 1999 (Cth) (EPBC Act) provides for the protection of the environment and conservation of biodiversity, including the protection, conservation and management of listed threatened species through the implementation of recovery plans. Successive recovery plans for threatened albatross and petrel species have been in place since 2001. This National Recovery Plan for threatened albatrosses and petrels (2021) replaces the National Recovery Plan for threatened albatrosses and giant petrels 2011–2016 (DSEWPC 2011b). The plan outlines the research and management actions necessary to stop the decline, and support the recovery of these species so that their chances of long-term survival in nature are maximised.
Seabirds remain among the world's most threatened bird species. Albatrosses and petrels in particular facing an ongoing conservation crisis (Phillips et al. 2016, ACAP 2019a). Many threatened albatross and petrel species breed and/or forage in Australia's jurisdiction and distribute widely across the world's oceans and remote, offshore islands (del Hoyo & Collar 2014, Menkhorst et al. 2017). These species face a range of threats to their long-term conservation status on land: particularly habitat degradation and predation by feral species; and at-sea: particularly incidental catch during fishing operations; as well as generalised threats: particularly marine pollution, marine plastics and climate change (Croxall et al. 2012, Phillips et al. 2016). The recovery of threatened albatrosses and petrels relies on an integrated approach involving actions at domestic and international levels.
This recovery plan provides a national strategy to guide the activities of government, industry, research organisations, and other stakeholders in protecting, conserving and managing threatened albatross and petrel species that breed and/or forage in Australia's jurisdiction. There may be synergies with other work areas or management regimes where opportunities are presented to leverage off existing conservation measures. Where possible collaboration and integration with existing programs should be explored and encouraged.
Although Australian breeding and/or foraging populations of albatrosses and petrels generally represent a small proportion of global populations, other than the endemic Thalassarche cauta (Shy Albatross), these species make a significant contribution to Australia's biodiversity. This plan will be made for each of the following 20 EPBC Act listed threatened species:
Albatrosses and petrels in Australia forage in higher latitude, maritime waters from Western Australia to Queensland, predominantly southwards of the parallel of 25°S, with eight of the species included in this recovery plan breeding on offshore islands of Tasmania (Albatross Island, Macquarie Island, the Mewstone and Pedra Branca), the external Territory of Heard Island and McDonald Islands, and the Australian Antarctic Territory (AAT) (Baker et al. 2002, Menkhorst et al. 2017). Many of these species distribute widely across the world's oceans in the higher latitudes of the southern hemisphere (del Hoyo & Collar 2014). Accordingly, this plan recognises that the recovery of threatened albatrosses and petrels relies on an integrated approach involving actions at domestic and international levels.
The recovery plan also outlines the major benefits to other albatross and petrel species in Australia that will be affected by its implementation. While not listed as threatened under the EPBC Act, these species occur in essentially the same areas, face the same conservation threats, require the same conservation actions, and are listed under the Agreement on the Conservation of Albatrosses and Petrels (ACAP), and included on theRed List of Threatened Species of the International Union for Conservation of Nature (IUCN) (IUCN 2021). Including the following additional albatross and petrel species in this plan makes it a more cogent document:
Phoebastria immutabilis (Laysan Albatross) is not included in this recovery plan. While considered under the previous plan (DSEWPC 2011a, 2011b), available scientific evidence indicates that the species predominantly has a northern Pacific Ocean distribution (ACAP 2012l), and is a rarely detected visitor to Australian waters adjacent to Norfolk Island (Moore 1999). It is not a listed threatened species under the EPBC Act. Consequently, this vagrant species does not warrant inclusion in the plan, and its conservation will not be affected by the plan's implementation.
This recovery plan is being made jointly by the Australian Government, and the governments of Western Australia, Victoria, Tasmania and Queensland. This joint approach recognises the wide distribution of albatrosses and petrels that breed and/or forage in Australia's jurisdiction. The approach ensures that complementary actions are taken by the Commonwealth, and affected states in areas under their respective control and responsibility. The Australian Government is committed to acting in accordance with the recovery plan and to implementing the plan as it applies to Commonwealth areas.
The recovery plan is supported by related frameworks that contribute to the conservation of albatrosses and petrels, in particular:
The recovery plan recognises that recovery of threatened albatrosses and petrels will take longer than the 10-year life of the current plan due to the long generation lengths of the species concerned (Bird et al. 2020). It further acknowledges that a recovery plan should remain in place for affected species until such time as the conservation status of the species breeding and/or foraging in Australia's jurisdiction has improved to the point where populations are considered secure. The plan aims to provide continuity for recovery actions for these long-lived species, recognising that within the five-year timeframe for reviewing progress under the plan there is insufficient time to determine accurately changes affecting the recovery of the species within Australia's jurisdiction. The plan also aims to provide continuity for international advocacy by Australia, particularly through ACAP, relevant regional conservation and fisheries bodies, and through engagement with range states, and international bodies with an interest and expertise in conserving these species.
2.1 Recovery plans
The Australian Government develops recovery plans for the purposes of the protection, conservation and management of listed threatened species under the EPBC Act. A plan may be made by the Commonwealth or jointly with one or more states and territories in which the threatened species occurs, or with agencies of one or more of those states and territories. Part 13 of the EPBC Act describes the process, content and consultation required when making or varying a recovery plan. A recovery plan may apply to one or more threatened species.
The legislation requires the Commonwealth to implement a plan to the extent to which it applies in areas under Commonwealth control and responsibility. In addition, Commonwealth agencies must not take any action that contravenes a recovery plan. Where a plan applies outside Commonwealth areas in states and territories, the Commonwealth must seek the cooperation of the affected jurisdiction, with a view to jointly implementing the recovery plan.
Successive recovery plans have been implemented to support the recovery of threatened albatrosses and petrels since 2001. Each plan has provided for the research and management actions necessary to stop the decline of, and support the recovery of, the listed threatened albatross and petrel species, so that the chances of long-term survival in nature of the affected species are maximised. Recovery plans made under the EPBC Act are subject to review within five years and sunset after 10 years. The recovery plan for threatened albatrosses and petrels will be the third recovery plan for these species under the EPBC Act, following the Recovery Plan for albatrosses and giant petrels made in 2001 (DEH 2001) and the National Recovery Plan for threatened albatrosses and giant petrels 2011–2016 made in 2011 (DSEWPC 2011a, 2011b).
2.2 Albatross and petrel species referred to in recovery plan
The taxonomy of albatrosses and petrels has benefited from a significant amount of new taxonomic information that has become available since the initial recovery plan for albatrosses and petrels. The recovery plan uses the taxonomy adopted by ACAP for a variety of reasons including its international standing, use of the most recent data, and review processes. The ACAP taxonomy is the same as that used by the IUCN for theRed List of Threatened Species (IUCN 2021) and the Convention on the Conservation of Migratory Species of Wild Animals (CMS).
Table 1 indicates the relationship between the ACAP taxonomy, and the taxonomy used under the EPBC Act for the albatross and petrel species referred to in the recovery plan. The use of the ACAP taxonomy does not substantially or practically alter the protection, conservation and management actions contained in the plan.
Table 1: Albatross and petrel species referred to in the National Recovery Plan for albatrosses and petrels.
A five-year review of the National Recovery Plan for threatened albatrosses and giant petrels 2011–2016 was conducted with the inclusion of managers, experts and stakeholders (Department of the Environment 2016). The review noted that within the five-year timeframe of the plan there was insufficient time to determine accurately population trajectories of threatened albatrosses and giant petrels. Caution was therefore appropriate when assessing the population status of the 21 albatross and giant petrel species referred to in the plan.
The Review found that of the 28 recovery criteria in the recovery plan, four had been met, while progress had been made against 20 criteria. Recognising that the recovery actions extended well beyond the five-year timeline for the review of the plan, the Review recommended that a future plan should include longer-term objectives and actions. Limited progress against objectives was found to be due to the expected long-term time scale for population recovery and criteria that were infeasible, impractical or unrealistic. The Review noted that of the 12 albatross and petrel breeding populations where monitoring occurred during the life of the plan, one was increasing, two remained stable or increasing, one population was too small to determine its trend, the status of three populations were unknown and five populations were declining. No data had been collected for the remaining eight populations for over 10 years. This was attributed to the logistical difficulties concerning access to those populations. Addressing the lack of data on conservation status for these remaining eight species was identified as a priority action for this recovery plan.
The successful eradication from Macquarie Island by 2014 of pest populations of European rabbits (Oryctolagus cuniculus), ship rats (Rattus rattus) and house mice (Mus musculus) was identified as a major achievement during the review of the recovery plan. This was the largest island eradication project attempted at that time (Hunt G (Minister for the Environment) 2014, Parks and Wildlife Service 2014, Alderman et al. 2019). The Review further noted cats (Felis catus) had been eradicated from Macquarie Island by 2002 (Robinson & Copson 2014).
The Review highlighted that the recovery plan provided a strong policy foundation for action domestically to conduct ongoing monitoring of albatrosses and petrels at key breeding sites in Tasmania (Albatross Island, the Mewstone and Pedra Branca) and at Macquarie Island in the sub-Antarctic.
The Review stressed that in the absence of effective international conservation action, Australia would be unable to secure the conservation of threatened albatrosses and petrels that breed and forage within Australia's jurisdiction. The Review recognised that the recovery plan provided an important framework for international conservation and fisheries forums to establish and improve conservation measures concerning seabird bycatch mitigation in fisheries, and to improve conservation of breeding populations on land.
The Review noted there had been varying degrees of implementation by regional fisheries bodies of conservation measures for seabird bycatch mitigation, and collection of bycatch information through scientific observer programs, and highlighted that further international efforts would be required to improve the effectiveness of these measures over time. Australia's influence and engagement in the work of ACAP was also considered highly influential in addressing threats to albatross and petrel species on land and at sea, including the development of best practice measures and improved conservation advice for range states, as well as states whose vessels fished in the range of albatrosses and petrels.
The Review noted that the threat of marine debris including plastics had increased in significance during the life of the recovery plan, and there is now particular concern about the threat posed by marine plastics to seabirds in the Tasman Sea (Wilcox et al. 2015), an area of high abundance for Australia's albatross and petrel species. The understanding of the potential effects of climate change, particularly concerning the endemic Shy Albatross (Thomson et al. 2015), has also increased during the life of the plan. This threat will likely assume greater significance in future for all species covered by this plan.
The Review concluded that a recovery plan for albatrosses and petrels should remain until such time as populations of affected threatened species breeding and/or foraging in Australia's jurisdiction have improved to the point where the populations are considered secure. The Review considered that the preponderance of key threats to albatross and petrel species remained, with the important exception of feral pest rabbit and rodent species on Macquarie Island that had been eradicated within the life of the existing plan. The potential scope and scale of marine debris including mircoplastics as a conservation threat had increased in light of improved information, however their effects on albatrosses and petrels at the population level would require further research.
The Review considered that an updated recovery plan should include objectives and actions that were ‘SMART’ (specific, measureable, achievable, realistic and timely) and be designed to advance the recovery of threatened albatross and petrel species over the longer term, in line with timeframes for population-level changes to be detected. The Review considered that additional species should be included encompassing those petrel species breeding and foraging in Australian jurisdiction that are listed under the Agreement on the Conservation of Albatrosses and Petrels. The Review concluded that a Recovery Team should be established to discuss implementation and effectiveness of recovery plan actions. The establishment, governance and terms of reference, participation, and frequency of meetings of this forum should be consistent with those for recovery teams for threatened species.
The outcomes of the Review have informed the development of this recovery plan with objectives and actions building upon previous recovery efforts.
2.4 Legal framework
Domestic legal frameworks
Commonwealth and state legislation affords protection to threatened albatrosses and petrels in Australia. The species referred to in this recovery plan may be listed as threatened under one or more relevant statutes of the Commonwealth, Western Australia, South Australia, Victoria, Tasmania, New South Wales and Queensland:
The status of each species under Commonwealth and state legislation is set out in Appendix B.
The recovery plan has been developed jointly by the Commonwealth and relevant states under Part 13 of the EPBC Act, and Part 7 of the Environment Protection and Biodiversity Conservation Regulations 2000 (Cth). These set out the content and consultation requirements for making a recovery plan including identifying threats to affected species, and habitats critical to the survival of the of the species.
The importance of albatross and petrel breeding sites in Australia's jurisdiction to the survival of Australia's albatross and petrel species has led to the introduction of access restrictions for all breeding locations in Australia's jurisdiction that are implemented through:
Australia's national efforts under the recovery plan contribute to global work to protect albatrosses and petrels and conserve their biodiversity by range States (Commonwealth of Australia 2019a). The plan assists in the implementation of Australia's international environmental responsibilities, in particular to give effect to Australia's obligations under the Agreement on the Conservation of Albatrosses and Petrels (ACAP) and the Convention on Biological Diversity (CBD). As well, the following additional international and regional conservation arrangements are of relevance to the plan:
The recovery plan also contributes towards addressing the impacts from high seas fishing activities affecting albatrosses and petrels as associated and dependent species. The following international and regional fisheries arrangements and instruments are of relevance to the plan:
Albatrosses and petrels are mostly surface seizing, pelagic predators that feed on live and moribund prey (Barton 1979, Harper et al. 1985, Harper 1987, Wood 1992, Croxall & Prince 1994). The ability to dive varies across species and involves either surface plunge dives or shallow dives to catch prey (generally <15 m) (Prince et al. 1994a, Hedd et al. 1997, Hedd et al. 2001, Robertson et al. 2006). Some species also prey on other seabirds and scavenge carrion on land (Cherel et al. 2002, Le Bohec et al. 2003).
Albatrosses and petrels are wide-ranging, opportunistic predators. Birds will forage singly and will aggregate in larger numbers where there is a rich food source (Dixon 1933, Brothers 1991). Individual species prefer to feed during the day or at night (often by moonlight) (Hedd et al. 2001, Phalan et al. 2007). Albatrosses and petrels have a diverse diet, depending on the availability of food, including cephalopods, crustaceans, cyclostomes, fish and tunicates, although diet is not well known for several species (Cherel & Klages 1998, Green et al. 1998, Hedd & Gales 2001, Xavier et al 2003a, 2003b). Albatrosses and petrels exhibit a tendency to follow fishing vessels, sometimes in large numbers involving various species (Dixon 1933, Brothers 1991). Competition for fisheries discards and baited hooks can be intense (van der Hoff 2001), with smaller birds subject to secondary attacks by other larger birds (Weimerskirch et al. 1986, Harper 1987, Brothers 1991).
Albatross and petrel species occurring in Australia's jurisdiction predominantly breed on remote, offshore islands in the higher latitudes, with the exception of the Northern Royal Albatross and Westland Petrel that breed on the South Island of New Zealand. The approach to nesting varies between and within species. Some breeding pairs will form solitary nests while others will nest in loose to dense colonies, or in mixed colonies with other seabird species. Nest construction varies between and within species. Nesting strategies include the construction of cupped pedestal mounds, nesting on the ground, slopes and cliffs, and in burrows, as well as nesting among tussock-grass, ferns, grassy meadows, scrub, and under forest canopies.
2.6 Habitats regarded as critical to the survival of the threatened species
Albatrosses and petrels are extremely site-faithful (Bried & Jouventin 1999, Gauthier et al. 2010) and the populations currently breeding at identified locations in Australia's jurisdiction are unlikely to breed elsewhere in our jurisdiction (Baker et al 2002). These remote offshore islands therefore should be regarded as habitat that is potentially critical to the survival of albatrosses and petrels in Australia (additional information on each breeding site is provided in Appendix C).
Albatross and petrel species breeding sites in Australia's jurisdiction are as follows:
Shy Albatross (endemic) breeds on three offshore islands adjacent to Tasmania: Albatross Island, the Mewstone and Pedra Branca (Brothers et al. 2001, ACAP 2013a, 2013d, 2013e, DPIPWE 2021b)
Black-browed Albatross, Grey-headed Albatross, Grey Petrel, Light-mantled Albatross, Wandering Albatross, Northern Giant Petrel, and Southern Giant Petrel breed on Macquarie Island in the sub-Antarctic (Brothers et al. 2001, ACAP 2013b, DPIPWE 2021a)
Black-browed Albatross breeds on Bishop and Clerk Islets in the sub-Antarctic adjacent to Macquarie Island (Brothers et al. 2001, Brothers & Ledingham 2008, ACAP 2014)
Black-browed Albatross, Light-mantled Albatross, and Southern Giant Petrel breed on the External Territory of Heard Island and McDonald Islands in the sub-Antarctic (ACAP 2013c, 2013f). Potentially, a small population of Wandering Albatross might be present on Heard Island (Kirkwood et al. 1989), although only a nest mound was found during a visit in 2001 (ACAP 2013c)
Southern Giant Petrel breed in the AAT at Giganteus Island (Mac.Robertson Land), Hawker Island (Princess Elizabeth Land), and Frazier Islands (Wilkes Land) (ATCM 2013, 2015, 2016).
The location and extent of albatross and petrel breeding sites in Australia's jurisdiction are provided in Table 2 and under each species profile (see Appendix A). Details of each of the habitats that are regarded as critical to the survival of threatened albatross and petrel species breeding within Australia's jurisdiction are set out in Appendix C.

Habitat identified as critical to the survival of the Grey-headed Albatross, Shy Albatross, and Wandering Albatross was identified when the initial recovery plan for albatrosses and petrels was developed in 2001 (DEH 2001, 2002, DAWE 2020). Albatross Island, the Mewstone and Pedra Branca comprise the only known breeding habitat for the endemic Shy Albatross. Macquarie Island is the only known suitable breeding habitat under Australia's jurisdiction for the Grey-headed Albatross, and Wandering Albatross. These locations are included in the Register of Critical Habitat under section 207A of the EPBC Act in recognition that the locations are breeding habitat critical to the survival of the species in Australia's jurisdiction, and these populations are important to ensuring the long-term viability and genetic diversity of the species (DEH 2002).
2.7 Key Biodiversity Areas
TheKey Biodiversity Areas (KBA) program aims to identify, map, monitor and conserve the critical sites for global biodiversity across the planet. This process is guided by a Global Standard for the Identification of Key Biodiversity Areas, the KBA Standard (IUCN 2016). It establishes a consultative, science-based process for the identification of globally important sites for biodiversity worldwide. Sites qualify as KBAs of global importance if they meet one or more of 11 criteria in five categories: threatened biodiversity, geographically restricted biodiversity, ecological integrity, biological processes, and irreplaceability. The KBA criteria have quantitative thresholds and can be applied to species and ecosystems in terrestrial, inland water and marine environments. These thresholds ensure that only those sites with significant populations of a species or extent of an ecosystem are identified as global KBAs. Species or ecosystems that are the basis for identifying a KBA are referred to as Trigger species.
The global KBA partnership supports nations to identify KBAs within their country by working with a range of governmental and non-governmental organisations scientific species experts and conservation planners. Defining KBAs and their management within protected areas or through Other Effective Area-based Conservation Measures (OECMS) will assist the Australian Government to meet its obligations to international treaties, such as the Convention on Biological Diversity. KBAs are also integrated in industry standards such as those applied by the Forest Stewardship Council or the Equator Principles adopted by financial institutions to determine environmental risk in projects.
The initial identification of a site as a KBA is unrelated to its legal status as it is determined primarily based on the distribution of one or more Trigger species at the site. However, existing protected areas will often inform the final KBA delineation, because KBAs are defined with site management in mind (KBA Standards and Appeals Committee 2019). In practice, if an existing protected area roughly matches a KBA, it will generally be used for delineating the KBA. Many KBAs overlap wholly with existing protected area boundaries, including sites designated under international conventions (for example, Ramsar and World Heritage) and areas protected at national and local levels (for example, national parks). However, not all KBAs are protected areas and not all protected areas are KBAs. It is recognised that other management approaches may also be appropriate to safeguard KBAs. The identification of a site as a KBA highlights the site's exceptional status and critical importance on a global scale for the persistence of the biodiversity values for which it has been declared for (particular Trigger species or habitats) and implies that the site should be managed in ways that ensure the persistence of these elements. More information about KBAs is available at: keybiodiversityareas.org/home.
The global KBA partnership currently recognises four Key Biodiversity Areas as important for albatross and petrel conservation in Australia's jurisdiction and to support the long-term persistence of the species. KBAs are also undergoing a regular revision to ensure changes in IUCN Red List status, taxonomic changes, local population trends, as well as increased knowledge of the species are reflected accurately in the KBA network. As such, over time, additional KBAs may be recognised for their importance for albatrosses and petrels or new KBAs may be declared for these and other taxa. Detailed KBA Factsheets, including boundary maps, population estimates of trigger species and scientific references for these seven areas (and other KBAs) are available from the World Database of Key Biodiversity Areas (BirdLife International 2020). The four KBAs in Australia's jurisdiction for albatrosses and petrels include:
Tasmania
Albatross Island and Black Pyramid Rock — two tiny islands offshore from the north-west of Tasmania. Albatross Island (33 ha) is very rocky, with a coastline of eroded boulders, gulches and caves and a short cover of grasses and herbs across the interior. Black Pyramid Rock (40 ha) is a basaltic rock stack surrounded by steep cliffs, steep grassy slopes and a small central plateau. It is sparsely vegetated as the Australasian Gannet (Morus serrator) has taken most vegetation as nesting material. The endemic Shy Albatross that breeds on Albatross Island is a trigger species for the KBA, with 30-35% of the world population breeding at this location.
Mewstone — a rocky oval-shaped 9 ha island, about 20 km south of Red Point, between Southport and Port Davey in south-west Tasmania. Composed of Muscovite granite, which is unknown elsewhere in the Southwest National Park, the island is very steep and mostly bare jagged rock. The few plant species present on the island are confined to crevices and cavities in the rock where soil has accumulated. The endemic Shy Albatross that breeds on the Mewstone is a trigger species for the KBA, with more than 60% of the world population breeding at this location.
Macquarie Island —a sub-Antarctic island located approximately halfway between Antarctica and Australia, about 1450 km south-east of Tasmania and 1300 km north of the Antarctic continent. The listing includes the island and the nearby Judge and Clerk Islets and Bishop and Clerk Islets. The island lies just to the north of an oceanic boundary, the Antarctic Polar Frontal Zone or Antarctic Convergence, where cold polar waters meet warmer sub-Antarctic waters. The island is 34 km long and up to 5 km wide and consists of a long plateau, 200-350 m above sea level, surrounded on all sides by steep slopes or cliffs. The island is free from invasive introduced species, after successive eradication efforts. The islands and seas to three nautical miles are a Nature Reserve, the islands and seas to 12 nautical miles are a World Heritage Area, and 162,000 km2 of seas to the east are in the Macquarie Island Marine Park. The Wandering Albatross, Light-mantled Albatross, Grey-headed Albatross, Black-browed Albatross, Southern Giant Petrel, and Northern Giant Petrel all breed on Macquarie Island and are trigger species for the KBA.
Commonwealth
Heard Island and McDonald Islands — islands forming an External Territory in the Southern Ocean, over 4000 km south-west of Western Australia and about 1500 km north of Antarctica. Heard Island is 368 km2 and dominated by Big Ben, an active volcano rising to Mawson Peak, at 2745 m. About 70% of the island is covered in snow and glacial ice and black volcanic rocks, with vegetation and bird nests and colonies restricted to the coastal fringe. The McDonald Islands group (~3.6 km2, max altitude 230 m, about 43 km west of Heard Island) includes McDonald Island and other smaller islands and islets. McDonald Island is also volcanic; since 1980, it has doubled in size and grown in height by almost 100 m as a result of lava flows in the 1990s. The islands form part of the 65,000 km2 Heard Island and McDonald Islands Marine Reserve and World Heritage Area that includes the islands, all inshore waters to 12 nautical miles and some offshore waters. The Wandering Albatross, Light-mantled Albatross and Southern Giant Petrel breed on these islands and are trigger species for the KBA.
3 Threats
3.1 Nature of threats
Albatross and petrel life history strategies are a major factor influencing their conservation. Procellariiform seabirds including the albatross and petrel species in this recovery plan are characterised by their longevity, naturally high adult survival rates, delayed sexual maturity and low fecundity (Warham 1990). Over the 60 years from 1950 to 2010, 324 monitored seabird populations have decreased by nearly 70% worldwide (Paleczny et al. 2015). Changes in adult mortality rates have greater impact on Procellariiform populations than other demographic factors (Croxall & Rothery 1991). Pelagic seabirds are more threatened than coastal resident seabirds, as they tend to have small breeding populations and many are restricted to single islands or island groups (Croxall et al. 2012). When a population cannot be stabilised through local recruitment or immigration, any additional mortality is likely to lead to a decrease of a population (Longcore & Smith 2013). The breeding season of albatrosses and petrels is typically protracted, and if during this time, one parent dies or is killed the death of the dependent offspring may occur, and a loss of breeding opportunities will occur until a new pair bond is established, further jeopardising population viability (Weimerskirch & Jouventin 1987, Croxall et al. 1990). Human activities, such as fishing, disturbance, development and pollution, as well as direct take, either kill seabirds directly or alter the structure and function of their ecosystem (Baum & Worm 2009). Significant modification of their breeding and foraging habitats due to changes to climate have the potential to also affect Australia's albatross and petrel populations directly and indirectly (Tweedie & Bergstrom 2000, Chown et al. 2005, Thost & Allison 2005, Thost & Truffer 2008, Thomson et al. 2015). Albatrosses and petrels are also susceptible to a wide range of diseases. However, the frequency of occurrence and impact of infectious diseases remains largely unknown (Uhart et al. 2018).
Albatrosses and petrels are subject to an array of threats throughout all stages of their life history (Dias et al 2019). These comprise terrestrial threats at breeding sites and marine threats that reduce the survivorship of albatrosses and petrels and/or their capacity to reproduce successfully (Baker et al. 2002, Phillips et al. 2016) (Table 4). Various aspects of albatross and petrel biology and ecology are still not well known. Such understandings are vital to the interpretation and measurement of the likely impact of threats and are important for population viability analysis and other modelling. Despite considerable work, particularly concerning foraging distribution (BirdLife International 2004), details of the breeding biology, feeding ecology, foraging distribution and population trend of many albatross and petrel species are still lacking because of a lack of long-term studies (Phillips et al. 2016). Cumulatively, these terrestrial and marine threats are putting the long-term viability of many species at risk. The threats and issues discussed below are grouped according to subject matter, and do not necessarily appear in order of importance.
The key terrestrial and marine threats to the survival of albatrosses and petrels are set out below. The list is not exhaustive, but identifies the main threats likely to cause one or more of the following adverse impacts affecting the species:
direct mortality
indirect loss of reproductive opportunities
disturbance including effects on nesting and/or foraging behaviour
morbidity including from injury, disease, and/or contamination
disorientation through artificial light and ship strikes
avoidance behaviours
abandonment of nests
damage to nesting habitat
loss of nesting habitat.
The information about the threats to the conservation of albatrosses and petrels is synthesised from a range of sources, noting that this information is likely to change over the life of this recovery plan. Prior to using any listing status against a species, please refer to the threatened species and ecological communities or Species Profile and Threats Database (SPRAT) webpages for current information. These data represent EPBC listed species that have been mapped by the Department and are available for public use, subject to Sensitive Species Policies, as a result of which some maps may be withheld.
Up-to-date information on particular species may be found at the following sources in particular:
NB. The distribution maps show modelled national distributions within the Australian context to support assessment of environmental impacts under the EPBC Act. Species distributions are indicative and not meant for local assessment. Planning or investment decisions at a local scale should seek some form of ground-truthing to confirm the existence of the species or ecological community at locations of interest.
3.2 Threat prioritisation
Each of the threats to albatrosses and petrels has been assessed to determine the risk posed to albatross and petrel populations using a risk matrix. This in turn determines the priority for actions outlined below. The threats were considered in the context of the current management regimes. The impact of that threat has been assessed assuming that existing management measures continue to be applied appropriately. If management regimes change, then the level of risk associated with threats may also change.
The risk matrix considers the likelihood of an incident occurring and the consequences of that incident. Threats may act differently in different parts of the species range and at different times of year. Population-wide threats are generally considered to present a higher risk.
The risk matrix uses a qualitative assessment drawing on peer reviewed literature and expert opinion. In some cases, the consequences of activities are unknown. In these cases, the precautionary approach has been applied. Levels of risk and the associated priority for action are defined as follows:
Very high — immediate mitigation action required.
High — mitigation action and an adaptive management plan required.
Moderate — obtain additional information and develop mitigation action if required.
Low — monitor the threat occurrence and reassess threat level if likelihood or consequences change.
Table 3: Risk prioritisation
Likelihood of occurrence Consequences
Not significant Minor Moderate Major Catastrophic
Almost certain Low Moderate Very High Very High Very High
Likely Low Moderate High Very High Very High
Possible Low Moderate High Very High Very High
Unlikely Low Low Moderate High Very High
Rare or Unknown Low Low Moderate High Very High
Categories for likelihood are defined as follows:
Almost certain — expected to occur every year.
Likely — expected to occur at least once every five years.
Possible — might occur at some time.
Unlikely — such events are known to have occurred on a worldwide basis but only a few times.
Rare or Unknown — may occur only in exceptional circumstances, OR it is currently unknown how often the incident will occur.
Categories for consequences are defined as follows:
Not significant — no long-term effect on individuals or populations.
Minor — individuals are adversely affected but no effect at population level.
Moderate — population recovery stalls or reduces.
Major — population decreases.
Catastrophic — population extinction.
3.3 Terrestrial threats
Human disturbance
Threats from human disturbance at or adjacent to breeding sites including direct habitat destruction, damage, and disturbance, as well as interactions with built structures and artificial lighting.
Coastal development involves the progressive encroachment of natural coastal habitat for human use. Such development has occurred and may occur onshore or on offshore islands. Encroachment of this natural habitat may directly reduce areas used by albatrosses and petrels as breeding sites. Adjacent coastal development may disturb breeding sites due to increased ambient noise, artificial light pollution, and barriers to movement. Additionally, coastal development may directly damage or destroy nesting habitat. As well, disturbance, habitat damage and predation may occur if domestic animals are allowed to stray or enter previously undisturbed natural habitat that is used by albatrosses and petrels as breeding sites.
Australia's albatross and petrel breeding populations are located on remote, offshore islands where coastal development is not presently a significant concern. Prior use of offshore islands, such as for sealing and feather collecting, abated by the early 20th Century. Access to islands where there are breeding populations of albatrosses and petrels is prescribed. Although there are permanent research stations located on Macquarie Island, and near to each of the Frazier Islands, Giganteus Island and Hawker Island in the AAT, all human activities are subject to management plans that aim to avoid or minimise disturbance of albatross and petrel breeding sites.
Coastal development of wind farm turbine infrastructure is an emerging issue, with wind farm proposals being considered for sites along the southern Australian coastline, and on offshore islands, for example in Bass Strait.
Many of the breeding sites for albatross and petrel species that breed beyond Australia's jurisdiction are located on remote offshore islands (Croxall et al. 2012). At some of these locations there are also local human populations with associated direct and indirect impacts on the breeding sites. As well, on the South Island of New Zealand there are breeding populations of Northern Royal Albatross (at Taiaroa Head) (ACAP 2012o) and Westland Petrel (at Punakaiki) (ACAP 2012w), which are also at risk of human disturbance.
Wildlife tourism is a worldwide phenomenon that attracts many visitors, in the early 2000s, more than 700 million usually organised trips were offered worldwide (Higginbottom 2004). However, wildlife tourism takes many forms ranging from non-organised or supervised wildlife observations or interactions to guided and carefully managed ecotourism ventures (Packer & Ballantyne 2013). Among wildlife tourism activities, bird watching ranks very high, and seabird colonies are particularly attractive tourist destinations (for example, Yorio et al. 2001). Wildlife tourism, recreational boating and fishing may disturb albatrosses and petrels at their breeding sites, as well as foraging birds adjacent to these locations.
Introduced invasive species
Threats from non-native species including predation, direct habitat destruction, degradation, damage, or disturbance.
Albatrosses and petrels are predominantly sensitive to terrestrial habitat changes that affect breeding sites. The progressive spread of human activity across the globe has led to the introduction of non-native animal and plant species to many previously pristine, remote offshore islands including those supporting albatross and petrel populations. While some non-native species were brought to these locations for food, or as domestic pets, other introductions occurred incidentally (for example, rats and mice on board ships). Introduced species may become pest species and threaten seabird populations on affected islands (Jouventin & Weimerskirch 1991, Thiebot et al. 2014).
Albatrosses and petrels are especially vulnerable to introduced mammals because of their lack of effective anti-predator behaviour, their habit of building their nests on the ground or in borrows and leaving chicks unattended during long-range foraging trips, and their low annual productivity (Baker et al. 2002). Invasive fauna may affect seabird populations via nest predation, nest destruction and habitat modification, with introduced grazing and browsing pest species impacting nesting sites by reducing cover, trampling nests and burrows, and increasing the risk of landslips (Croxall et al. 1984, Moors & Atkinson 1984, Robertson & Bell 1984).
Invasive flora species may affect breeding sites of albatrosses and petrels. The invasive flora causes adverse habitat modification, particularly through overgrowing nesting habitat, and creating a barrier to accessing breeding sites, including inhibiting access to burrows.
All breeding sites in Australia's jurisdiction are presently free from introduced species of fauna and flora that may cause population level impacts to albatross and petrel populations. Previous eradication efforts have eliminated feral cats, rabbits, rats and mice from Macquarie Island, the only breeding site in Australia where introduced pest species threatened local populations of albatrosses and petrels, with populations recovering at differing rates (Parks & Wildlife Service 2014, Buller et al in review a, in review b).
While Australian breeding sites are currently free of predators, the risk of introductions is always present, particularly where islands are visited regularly by humans. Ongoing vigilance is needed, in particular, concerning maintaining the human presence at Macquarie Island station, and during occasional visits by tourist vessels to the island, as well as research and management and tourist vessel visits to other islands. Australian and Tasmanian government agencies are working together to achieve the highest level of biosecurity for transport of goods and people to Macquarie Island. The danger to already threatened populations of albatrosses and petrels, in particular, could increase if the introduced pest free status of any breeding site was lost. Quarantine and other regulations are in place at all Australian breeding sites to minimise this threat.
Introduced invasive species remain a significant problem at breeding sites for many of the albatross and petrel species that forage in Australian waters but breed beyond Australia's jurisdiction.
Competition with native species
Threats from competition with native wildlife including direct damage to nesting habitat and predation.
Albatrosses and petrels, and many other seabirds typically occupy isolated, often relatively small islands. As a consequence, competition (both within and between species) for limited nest space can be intense, particularly on smaller islands.
Interspecific competition for nest space is a potential threat to the Shy Albatrosses breeding population on Pedra Branca where nest sites are limited (DPIPWE 2021b). The number of Australasian Gannets on Pedra Branca has been increasing, while the number of Shy Albatrosses at this location has been decreasing (Bunce et al. 2002, Alderman et al. 2011). Interactions between gannets and albatrosses are still poorly understood, but gannets may be removing nesting material, and displacing Shy Albatross from potential nesting sites, particularly in areas where gannets outnumber albatrosses. Further investigation is underway into the nature and extent of the inter-species interaction, and to explore management options. Following a successful trial on Albatross Island in 2017, 18 artificial nests made of aerated concrete were deployed on Pedra Branca in 2019 at four different sites with cameras set up to monitor each location (DPIPWE 2021b). It is hoped that the artificial nests will improve the breeding success of Shy Albatross nesting on Pedra Branca, as occurred on Albatross Island, where breeding success on artificial nests was found to be double that of natural nests (DPIPWE 2021b).
Disease
Threats from native and non-native pathogens.
Outbreaks of infectious diseases can have catastrophic consequences for albatross and petrel populations (Barbosa & Palaios 2009). The effect and severity of a disease can depend upon, among other factors, environmental conditions, the strain of the pathogen, the age of a bird, its health status and tends to vary among the various bird species (Woods 2004, Young & van der Werf 2008).
The flea and tick (Ixodes eudyptidis) borne Phlebovirus (Hunter Island Group virus I) was a major cause of Shy Albatross chick mortality during some years at Albatross Island (Woods 2004, Wang et al. 2014, Uhart et al. 2018). Heavily infested nestlings carried ticks clustered around the gape and along the soft, exposed skin on the underside of the bill. Such chicks appeared weak and underweight, and ultimately died (MacDonald & Green 1963, Johnstone et al. 1975). The effects of this avian poxvirus vary inter-annually, and infestations can reduce breeding success to only 10% in some colonies. Thus, disease may be a significant factor restricting the recovery of the Albatross Island population (Johnstone et al. 1975, Woods 2004). Disease links with climate change are likely (Thomson et al. 2015). Ticks on adults and chicks at colonies of Black-browed Albatrosses at the Falkland Islands/Islas Malvinas spread an avian pox virus causing localised sporadic mortality; these ticks are also present on Macquarie Island (Selkirk et al. 1990).
Beyond Australia's jurisdiction, the outbreak of two diseases in the 1980s (Avian Cholera and the pathogenic bacterium, Erysipelas sp.) are notable (Weimerskirch 2004). These caused a decline of the Indian Yellow-nosed Albatross population on Amsterdam Island, a key breeding site for this species, comprising 55% of the global population (ACAP 2012k). These diseases affect mainly young chicks, with a cyclic pattern between years, but also kill adult birds. The diseases potentially also threaten the Amsterdam Albatross and Sooty Albatross breeding populations at this location (Weimerskirch 2004).
The impact of disease on albatrosses and petrels is poorly studied. However, a recent review documented the occurrence of disease vectors in Antarctic seabirds and showed, for example, that 44% of species examined carried gastrointestinal parasites, 33% had potentially harmful bacteria, and 80% were infected with ectoparasites, such as lice (Barbosa & Palacios 2009). DNA analysis of scat samples of Shy Albatrosses revealed a high occurrence of tapeworm and roundworm DNA (McInnes et al. 2017a).
Geological processes
Threats from volcanic activity or earthquakes, including tsunamis and landslips.
Volcanic activity may impact breeding sites of seabirds through damage or destruction of habitat from eruptions including from resulting lava flows and ash debris. Contrastingly, volcanic activity may result in new environmental niches suitable for colonisation by seabirds.
Active volcanoes on Heard Island and McDonald Island in Australia's sub-Antarctic jurisdiction have erupted several times in recent decades (Stephenson et al. 2005, Commonwealth of Australia 2014). There is evidence of significant displacement of seabirds on McDonald Island following an eruption in 1992 (Crossin et al. 2013). The size of this island has also increased dramatically since then, providing potentially new habitat for seabird species including albatrosses and petrels.
Depending on their magnitude and location, earthquakes, either on land or undersea, may trigger landslips, liquefaction or a tsunami that may lead to damage or destruction of nesting habitat for seabirds particularly nearshore, and ground and burrow nesting petrels. The potential for earthquake effects on Australian breeding populations of albatrosses and petrels is poorly understood. Macquarie Island is seismically active with significant past earthquakes.
The recovery plan recognises that there are no feasible actions that might be taken to mitigate the threat posed by geological processes on albatrosses and petrel populations at affected locations.
Climate variability and change
Threats from climate variability and climate change resulting in significant weather changes beyond historical variance, with effects on life history, breeding behaviour and success, breeding habitat condition, and disease prevalence.
Climate change is causing major shifts in the distribution of species throughout the world. However, the consequences for ecosystems and community dynamics are not well understood (Albouy et al. 2014). How seabirds will respond to climate change and whether or not they are capable of adapting to new conditions remains largely unknown (Thompson et al. 2015). If species are unable to adapt, they will be vulnerable to extinction, in some cases because climate change will not be the only pressure experienced.
To be able to adapt, species need to have the ability to alter behaviour, and the capacity to evolve and adapt quickly to changing conditions. However, this option is probably limited for albatrosses and petrels, as they are long-lived, exhibit strong fidelity to breeding sites, and the conditions at the breeding sites can change rapidly.
Acquiring information that demonstrates climate change impacts is often not straightforward because of the complexity and interrelationships of environmental variables. For many seabird species long-term studies are not available and base line data are missing. But there are likely to be species-specific responses, because of the variation in life histories and adaptations among seabirds. Shifts in wind patterns, for example, are strongly linked to El Niño/La Niña events in the Pacific Ocean. Incubating Laysan Albatrosses increased their body mass in El Niño conditions and bred more successfully than during La Niña events, while Black-footed Albatrosses (Phoebastria nigripes) did not benefit from these conditions (Thorne et al. 2016).
Climate change is already altering the phenology (timing of life cycle events) of some species. A long-term study (55 years) of a seabird community in East Antarctica found that some species arrived 5-30 days later at their breeding colonies than in the 1950s, while others also laid their eggs a few days later than six decades ago (Barbraud & Weimerskirch 2006). Seabirds have to ensure that resource availability continues to coincide with the critical phases in their breeding cycles (Brown et al. 2016), but the phenology of their prey does not necessarily alter to the same extent. This could lead to a mismatch in timing of breeding and food availability. Alternatively, seabirds may shift their distribution if conditions have become more favourable elsewhere. However, such biogeographic shifts, if possible, result in major changes to ecosystem structure, species abundance and biodiversity (Beaugrand 2014).
Different effects of climate change are already observed among birds of the same species but of different ages. For example, among Black-browed Albatross monitored for over 40 years, the survival of middle-aged birds was reduced in years when sea surface temperatures in foraging areas were elevated, while old and young albatrosses survived better than in cold years (Pardo et al. 2013). As well, while generally regarded as monogamous, pair separations of Black-browed Albatross have increased at New Island in the Falkland Islands/Islas Malvinas from 1% to 8% across years due to warmer seas surface temperature anomalies arising from climate change environmental variability (Ventura et al. 2021).
The breeding success of Amsterdam Albatrosses, monitored annually from 1983 to 2006, was reduced in years of elevated sea surface temperatures in spring and summer, while warmer sea surface temperatures in the species’ wintering grounds did not appear to have a measurable effect (Barbraud et al. 2011). Further understanding of how populations will respond to climate change will be necessary for a successful assessment of impacts on breeding performance, success and survival.
Climate change may also act as a catalyser of epizootics, especially infectious diseases (Altizer et al. 2013). The effect of changing patterns of transmission of infectious diseases, such as Avian Cholera (Uhart et al. 2018), may pose a major threat for albatrosses and petrels in the future, especially in the Southern Ocean environment where ecosystems have evolved in isolation (Weimerskirch 2004, Phillips et al. 2016).
Climate change may have deleterious weather-based effects including elevated temperatures (heatwaves), changes in rainfall patterns, and storm surges (Thompson et al. 2015, Phillips et al. 2016). These may adversely affect nesting habitat, through the loss of moisture for plants used in building nests. At Heard Island, climate change is having a dramatic impact including changes in weather patterns and glacial retreat, with vegetation and lagoons now existing where once there were sea-front, glacier snouts (Thost & Allison 2005, Thost & Truffer 2008).
Local climatic conditions have been shown to impact breeding success and the population status of the endemic Shy Albatross, and impacts are likely to increase in a changing climate (Thomson et al. 2015). A current doctorate research project aims to further the ecological understanding of Shy Albatross and the influence of climate variability and change to inform a decision-making framework to guide future conservation and management of the species (DPIPWE 2021b).
Storms and cyclones can seriously affect the nesting substrate, vegetation and wildlife on islands, in addition to affecting seabirds at sea. Such natural factors place additional pressures on seabird populations. At Pedra Branca significant storm surges can occur that overwash this Shy Albatross breeding site (DPIPWE 2021b). On the Sisters, the Pyramid and Forty-fours Islands in the Chatham Islands Group (New Zealand), a severe easterly storm in 1985 stripped the islands bare of vegetation and soil cover (Robertson 1998). Chatham Albatrosses breeding on these islands were unable to construct proper nest sites, and consequently egg mortality increased significantly. To compound the problem, most of the breeding population of the normally biennially nesting Northern Royal Albatross now nests annually owing to low breeding success, thus further limiting nest site availability (Robertson 1998, Taylor 2000).
The potential for degradation and loss of suitable habitat due to climate change is a threat to all Australian albatrosses and petrels. Management of this threat requires both domestic and international action. Long-term monitoring studies are needed to assess status and trends of albatross and petrel populations, as well as changes in their phenology and distribution. Monitoring of environmental conditions in parallel with albatross and giant petrel breeding parameters will help to determine any correlation. The potential for intervention options has been examined for the endemic Shy Albatross (Alderman & Hobday 2017). Interventions including artificial nests and use of avian-friendly pesticides have been shown to increase breeding success and are potential responses to assist the species to adapt to climate change (DPIPWE 2021b).
3.4 Marine threats
Fisheries interactions and bycatch
Threats from interactions between seabirds and fishing gear.
Seabirds are opportunistic predators and scavengers of surface and near surface prey (Harper et al. 1985), and follow fishing vessels to scavenge on discards and baited hooks, and prey on fisheries catch during hauling (Baker et al. 2002, Patrick et al. 2015, Collet et al. 2017, Collet & Weimerskirch 2020). Seabirds interact with fishing gear either by being struck by, hooked on, or entangled in the fishing gear (DAWR 2018), which may result in direct mortality or serious injuries leading to subsequent death (Huin & Croxall 1996, Commonwealth of Australia 2018b). Direct mortalities from interactions with fishing gear may lead to a loss of reproductive opportunities from the death of offspring if the remaining adult is unable to adequately incubate the egg, or provision the chick before fledging, and from lost breeding opportunities while the remaining adult seeks to establish a new pair bond to recommence breeding.
Incidental mortality from interactions with fishing operations is a widespread, pervasive, high-impact threat to pelagic seabirds, particularly albatrosses and petrels (Croxall et al. 2012, Phillips et al. 2016). High rates of seabird bycatch occur in a wide range of longline (Brothers 1991, Gales 1998, Anderson et al. 2011), trawl (Bull 2007, Croxall et al. 2012), purse seine (Baker & Hamilton 2016, Suazo et al. 2017), and gillnet fisheries (Žydelis et al. 2013).
Available evidence highlights the threat posed to seabirds from fisheries. Anderson et al. (2011) estimated at least 160,000, and potentially 320,000, seabirds are killed by longlines annually. In 2016, an estimated 36,000 seabirds (and potentially up to 110,000 seabirds) were bycaught in pelagic longline fisheries in waters southwards of the parallel of 25°S (BirdLife International (South Africa) 2019). Global estimates for seabird mortalities in trawl and purse seine fisheries are not available. Žydelis et al. (2013) estimated at least 400,000 seabirds die in gillnets each year.
Seabird bycatch levels are likely to be significantly underestimated due to cryptic mortalities. Interactions with pelagic longlines may have killed twice the number of seabirds than previously thought due to cryptic mortalities (Brothers et al. 2010, Debski & Pierre 2014). At least 23% of total mortalities were not observed during demersal trawl fishing (Parker et al. 2013).
Conservation and research efforts have been, and continue to be, directed towards understanding interactions between seabirds and fishing gear and preventing population declines from this threat (Bull 2007, Croxall et al. 2012). Effective mitigation measures have been developed for longline fisheries and are undergoing further refinement and development of cost-effective alternatives (FAO 1999, Commonwealth of Australia 2018b, ACAP 2021a, 2021c). Progress is also being made into effective mitigation methods for trawl, purse seine and gillnet fisheries, but this is less advanced than longline fisheries (FAO 2009, Maree et al. 2014, Parker & Molloy 2017, Suazo et al. 2017, ACAP 2019c). Challenges remain in encouraging various international fisheries management bodies to adopt best and improving mitigation technologies and techniques and verify compliance (Phillips et al. 2016, ACAP 2019a).
Longline fishing operations
Longline fishing involves the setting and hauling of one or more lines (mainline) that contain many individual hooks on branch lines (or snoods). The mainline can either be anchored or drifting, oriented vertically or horizontally, and varies considerably in length and number of hooks. Longline fishing can be pelagic (set midwater) or demersal (set on the seabed).
Longline fishing still is a major threat affecting albatrosses and petrels because of the high level of incidental mortality (Yeh et al. 2013). Each year, many thousands of albatrosses and petrels are accidentally killed on hooks deployed by pelagic longline fishing vessels (Baker et al. 2002). In demersal longline operations, where hooks are deployed at a much faster speed and are attached to shorter snoods than in the pelagic operations, seabirds get caught by the fast-descending hooks or entangled in branchlines when chasing after bait (Robertson et al. 2006). Although most mortality occurs directly when birds are caught during line-setting and, less commonly, hauling, albatrosses and petrels may also die after they are released with critical injuries (Huin & Croxall 1996), or following ingestion of fishing hooks when birds swallow discarded baits and fish heads containing hooks. In most cases, the death of breeding adults will lead to the subsequent death of dependent chicks.
All species of albatross and petrel breeding in Australia's jurisdiction may be bycaught during longline fishing operations (Thiers et al. 2014, Thiebot et al. 2015, Phillips et al. 2016). The implementation of successive Threat Abatement Plans for the incidental catch (or bycatch) of seabirds during oceanic longline fishing operations have significantly reduced seabird bycatch in Commonwealth-managed fisheries (Commonwealth of Australia 2018b).
The Threat Abatement Plan establishes performance criteria for each Commonwealth-managed longline fishery, and describes the management actions that the Australian Fisheries Management Authority will take if these criteria are exceeded. The plan highlights that to continue the downward trend and minimise or avoid bycatch, further innovation in mitigation will be necessary (Commonwealth of Australia 2018b). For example, in the Eastern Tuna and Billfish Fishery trials are underway of several new and/or modified seabird mitigation measures to further reduce bycatch rates (FRDC 2020).
For Australian longline fisheries in the sub-Antarctic at Macquarie Island, and Heard Island and McDonald Islands, additional management measures are implemented by the Australian Fisheries Management Authority to protect local breeding populations of seabirds. These measures include, but are not limited to, seasonal closures during the peak breeding season (for species breeding during the Austral summer), seabird bycatch limits, internally weighted longlines, retention of offal, and on-board observers of fishing operations. The additional measures have led to very few seabirds now being bycaught in the two fisheries.
Contrastingly, a significant threat remains in areas beyond Australia's jurisdiction (Phillips et al. 2016, Abraham et al. 2019). As well, the distribution of some albatrosses and petrels breeding in Australia's jurisdiction overlaps extensively with longline fisheries in areas beyond Australia's jurisdiction (Birdlife International 2004). Compliance with mitigation measures remains a key issue as non-compliance leads to significant increases in seabird bycatch.
A key mechanism for promoting and ensuring compliance in high seas fisheries is through independent monitoring of fishing operations. However, for many of the world's fisheries, observer coverage is either non-existent or falls below levels required to estimate seabird bycatch levels accurately (Dietrich et al. 2004, Small 2005, Baker et al. 2007). The use of electronic monitoring systems that employ cameras to independently monitor fishing operations, show potential in improving reporting of seabird bycatch by vessel operators (Tremblay-Boyer & Abraham 2020). However, the utility of electronic monitoring in high seas fisheries is unclear, as fishing vessels may be absent from home ports for extended periods, and the retrieval and audits of footage may be considerably delayed.
According to circumstance, a range of mitigation measures have been developed to reduce the incidental catch of seabirds in longline fisheries (Brothers et al. 1999, Dietrich et al. 2004, Bull 2007). They include night setting, line weighting, bird scaring lines, seasonal and/or area closures, avoidance or control of offal discharges, and hook shielding devices (Commonwealth of Australia 2018b, ACAP 2021a, 2021c). The mitigation measures reduce bycatch mainly during setting, by increasing the sink rate of baited hooks to get them quickly out of the reach of diving seabirds, and by minimising the congregation of seabirds around vessels. Innovation in seabird bycatch mitigation in longline fisheries is ongoing (for example, Robertson et al. 2014).
Each measure has different attributes, costs and potential to reduce seabird catch successfully. However, in most longline fisheries, the greatest reduction in bycatch comes from using a combination of measures. Some measures, such as night setting and line weighting, have been consistently successful in a number of longline fisheries, while the effectiveness of others has varied between vessels and seabird species (ACAP 2021a, 2012c).
Trawl fishing operations
Seabird mortality may be higher in trawl fisheries than in longline operations, at least in some areas of the globe, due to the higher fishing effort in this sector (Favero & Seco Pon 2014). Seabird mortality arises where birds are struck by warp wires (Sullivan & Reid 2002, 2003) or net sonde cables (Weimerskirch et al. 2000, Wienecke & Robertson 2002), or become entangled by these or the trawl net (Sullivan et al. 2006b). The seabird may be killed by the collision, or drown, or die later from its injuries (cryptic mortality). The type of trawl fishing and the time of year are important factors influencing the extent of seabird mortality. The problem of interactions with trawl gear is exacerbated when large numbers of birds are present around vessels, such as may occur when offal is discharged during processing of catch. Only a small proportion of the birds killed are hauled on board during fishing operations (Abraham 2010, Debski & Pierre 2014, Parker et al. 2013).
A major limitation in the gathering of accurate data is the lack of independent observer programs in trawl fisheries that would aid in the determination of lethal and sub-lethal seabird interactions with trawl gear. Reliable data on the levels of seabird bycatch in Australian trawl fisheries would require observer programs and/or greater levels of electronic monitoring to be established to specifically focus on this issue.
Although in Australia's trawl fisheries seabird bycatch appears to be relatively low, large numbers of albatrosses and petrels are killed in trawl fisheries worldwide (Sullivan & Reid 2002, González et al. 2006, Sullivan et al. 2006b, Baker et al. 2007, Bull 2007, Croxall et al. 2012, Paz et al. 2018). The foraging distribution of some albatrosses and petrels breeding in Australia's jurisdiction overlaps extensively with trawl fisheries in areas beyond Australia's jurisdiction (Birdlife International 2004). At times, seabirds attend fishing vessels in distant fisheries in large numbers where they are exposed to collision and entanglement risks (Wienecke & Robertson 2002, González et al. 2006, Baker et al. 2007).
At Macquarie Island, a single trawler operated in waters adjacent to the island from 1994 to 2009. There have been no deaths of albatrosses and petrels recorded. During trawl fishing at Heard Island and McDonald Islands only a few seabird deaths were recorded (Lawton et al. 2007). There is considerable trawl fishing elsewhere within Australian waters with vessels targeting a range of deep-water crustacean and finfish species. Much of this fishing effort occurs within areas frequented by albatrosses and petrels, including areas near important breeding colonies around Tasmania (Sagar et al. 2000). Because of high levels of cryptic seabird mortality in trawl fisheries, independent observers have been specifically tasked with quantifying seabird interactions (Baker et al. 2002, Sullivan et al. 2006a).
Since these investigations identified significant levels of albatross and petrel bycatch, the Australian Fisheries Management Authority now requires all vessels to develop an appropriate seabird management plan to manage risk factors, such as offal discharges, and to employ appropriate mitigation measures, to help reduce bird interactions with trawl warp wires (AFMA 2022b).
Studies to determine the effectiveness of seabird mitigation measures in trawl fisheries are not as advanced as in longline fisheries (FAO 2009, ACAP 2021b). Not discharging offal and limiting factory discharge to 'dirty water’ when the trawl gear is in the water reduces interactions between seabirds and gear as less birds are attracted to the vessel (Sullivan et al 2006a ACAP 2021b). Various devices have been developed to reduce warp and net sonde cable strikes (for example, Løkkeborg 2011). Bird scaring lines can also be effective (Sullivan et al. 2006a, Melvin et al. 2011). A combination of mitigation measures is recommended to reduce seabird mortality (Bull 2007, ACAP 2021b). Innovation in seabird bycatch mitigation in trawl fisheries is ongoing (for example, Koopman et al. 2018), however, further studies are required to identify and determine the efficacy of new mitigation technologies and techniques.
Gillnet fishing operations
Globally, gillnet or driftnet fisheries have a significantly higher bycatch rate for seabirds, marine mammals and sea turtles than longline and trawl fisheries (Lewison et al. 2014). Due to the excessive levels of bycatch (approximately 500,000 seabirds per year in the North Pacific alone) (Eisenbud 1985), the UN General Assembly called for a global moratorium on pelagic driftnetting in 1991 (Resolution 44/225), with many nations, including Australia, implementing legislation to ban large-scale driftnetting. Some illegal setting of driftnets still occurs, mainly in the northern hemisphere (Žydelis et al. 2013). Small-scale gillnet fisheries still operate in many EEZs and harm bird populations. In the Baltic and North seas alone, they may kill up to 200,000 waterbirds per year (Žydelis et al. 2009).
Demersal gillnets that touch the sea floor are the only type of gillnet permitted in Commonwealth fisheries (AFMA 2022a). These nets are usually set in waters less than 100 metres deep, and are used by commercial operators and recreational fishers. Although most states in Australia have declared the use of recreational gillnetting illegal, it is still permitted in Western Australia and Tasmania (Lyle et al. 2014). In Australia, the impact of gillnetting on albatrosses and petrels is only recently emerging in Commonwealth-managed fisheries where electronic monitoring records are available (see AFMA Protected Species Interaction Reports). The impact of recreational gillnetting on albatrosses and petrels is unlikely to be significant as nets are set in nearshore waters where these birds do not usually occur.
The significance of albatross and petrel bycatch by global smaller driftnet and fixed gillnet fisheries is unknown, and of concern. Few seabird bycatch reduction methods have been developed for gillnet fisheries, although increasing the visibility of the net reduces seabird bycatch for some species (Bull 2007). Further studies are required to identify and determine the efficacy of mitigation technologies and techniques, and potential management options to reduce the impacts of gillnet bycatch.
Deliberate take
Threats from intentional killing of adults and juveniles.
Although it is an offence under the EPBC Act and related state legislation, threatened albatrosses and petrels are sometimes intentionally shot for sport by recreational fishers or to reduce scavenging from commercial fishing vessels both inside and outside of Australian waters (Blakers et al. 1984, Tomkins 1985, Adams 1992). The prevalence of such practices and the extent to which they persist is unknown.
Beyond Australia's jurisdiction, there are reports of incidental and intentional take of albatrosses for purposes of sport, food, and use as bait (Phillips et al. 2016), in artisanal and commercial longline, gillnet, and jigging fisheries in waters off South America (Stagi et al. 1998, Awkerman et al. 2006, Alfaro-Shigueto et al. 2016), and southern Africa (Adams 1992).
There are also reports of bill mutilation of albatrosses and petrels in the southwest Atlantic Ocean associated with the removal of hooks from bycaught birds (Gianuca et al. 2020). These mutilation practices cause morbidity and eventual death of affected birds, and are occurring despite the widespread availability of guidelines for the safe removal of hooks from bycaught seabirds (ACAP 2019b).
Marine pollution
Threats from marine pollution, contamination and debris, including plastics and microplastics.
Fuel and oil spills
Bulk fuel and/or oil spills are caused through a variety of factors, such as groundings, explosions, collisions or the blowing out of wellheads near drilling sites. Oil spills can have catastrophic impacts on seabird populations. One of the most widely publicised spills was caused by the grounding of the Exxon Valdez in Prince William Sound, Alaska, in 1989 where 37,000 tonnes of crude oil was lost into the marine environment (Piatt & Ford 1996). Over the six months following the spill about 30,000 carcasses of oiled birds were collected. However, many affected birds are never found as they die at sea, and those collected present only a small percentage of the actual mortality. Some 250,000 birds are estimated to have perished as a consequence of the Exxon Valdez oil spill (Piatt & Ford 1996). These effects continue well after the spill (Irons et al. 2000), with many affected seabird populations showing no sign of recovery and some species continuing to decline a decade later (Lance et al. 2001).
The extent of the environmental damage depends upon the location and the time of a spill. For example, in July 1995, the Iron Baron struck a reef near Low Head in northern Tasmania. About 550 tonnes of bunker oil were spilled over 20 days. This event occurred in Tasmania's most important breeding area of Little Penguins (Eudyptula minor) whose breeding season had just started. More than 2100 birds were rescued, the majority of which were penguins (Goldsworthy et al. 2000).
Diving seabirds and surface feeders are negatively affected by oil spills. When seabirds dive through or feed on an oil slick the body becomes physically smothered compromising the bird's insulation and waterproofing which increases heat loss, often resulting in mortality. Severely oiled birds are unable to hunt and capture prey efficiently and the matted plumage reduces the bird's buoyancy and may cause them to sink and drown (Baker 1983, GESAMP 1993).
Furthermore, petroleum products are toxic to birds when ingested. Seabirds swallow oil either when they preen the soiled feathers or when feeding, for example, through scavenging oiled carcasses. Bunker and crude oils irritate intestines affecting the uptake and transport of electrolytes and water. This can retard the growth of chicks (Boersma et al. 1988). Intestinal irritations can also lead to bleeding (Fry & Lowenstine 1985). Adrenal and other glands are also negatively affected by oil ingestion as are liver and kidneys. Ingested toxins suppress the immune system of birds and reduce their reproductive efforts (Burger & Fry 1993, Burger & Gochfeld 2002).
On a broader ecological scale, oil may be retained in sediments for many years, leading to the temporary or permanent loss of species critical to the ecological balance of an ecosystem. In addition, crude oil is essentially a mixture of many hydrocarbon compounds, some of which are toxic and/or persistent. These can accumulate in the marine food chain (described above) and may potentially lead to lethal or sub-lethal changes in metabolic functions (Baker 1983, GESAMP 1993). Albatrosses and petrels are highly vulnerable to the hazards of oil or fuel spills as they spend much of their foraging time on the sea surface (Baker et al. 2002).
Chemical contaminants
The two broad categories of chemical pollutants are persistent organic pollutants (POPs), such as polychlorinated biphenyls (PCBs) and polychlorinated naphthalenes (PCNs), and heavy metals, such as mercury and cadmium. PCBs and PCNs are a mixture of chlorinated compounds that do not occur naturally. These compounds are highly toxic and, depending on concentration and exposure time can lead to a variety of serious health effects (Agency for Toxic Substances and Disease Registry 2000).
POPs and heavy metals are now global contaminants reaching regions far from their original areas of production or use. Elevated levels of POPs and heavy metals have been found in the plasma of adults, chicks and eggs of seabirds from every continent (including Antarctica) and virtually all islands across the globe (Croxall et al. 1984, Auman et al. 1997, Ludwig et al. 1998). Carrion feeders, such as albatrosses and petrels, had noticeably higher levels (Becker et al. 2016). POPs and mercury contamination can lead to reduced hatching and fledging success, and can disrupt the endocrine system, that is the secretion of hormones that regulate behaviours (Tartu et al. 2015, Goutte et al. 2014). As albatrosses and petrels are long-lived and typically highly dispersive, they tend to accumulate high levels of chemical contaminants (Muirhead & Furness 1988, Luke et al. 1989, Lock et al. 1992, Auman et al. 1997, Ludwig et al. 1998, Stewart et al. 1999), with the potential risk of population declines (Luke et al. 1989, Auman et al. 1997, Ludwig et al. 1998).
A number of albatross and petrel species carry unusually high concentrations of heavy metals, in particular cadmium and mercury (Muirhead & Furness 1988, Luke et al. 1989, Lock et al. 1992, Thompson et al. 1993, Stewart et al. 1999, Hindell et al. 1999, Becker et al. 2002). Mercury levels in the liver in Wandering, Sooty and Northern and Southern Royal albatrosses are among the highest recorded for free-living birds (Stewart et al. 1999, Goutte et al. 2014).
Marine debris
Marine debris comprises a variety of materials including timber, glass, rubber, metal and plastics. An estimated 80% of marine debris originates from terrestrial sources, and a large percentage of it is plastics (Allsop et al. 2006). Marine debris from human sources is increasing in scale and distribution across ocean systems globally (Andrady 2011, Jambeck et al. 2015, Roman et al. 2020). Low density plastic particles will float on the sea surface. For example, in the early 2010s, the concentration of plastic particles on the ocean surface around Australia averaged about 4260 pieces per square kilometre, but ranged from zero to around 50 000 pieces per square kilometre (Reisser et al. 2013), and is predicted to rise significantly in coming decades (Wilcox et al. 2015). Marine plastic pollution is now ubiquitous as wind and currents carry the debris into remote regions. Over time, plastics break up into smaller and smaller particles while the total quantities are still increasing (Barnes et al. 2009).
Marine plastic pollution impacts seabirds in a variety of ways. However, the rate of this source of morbidity and mortality remains unknown (Laist 1997, Kühn et al. 2015). Entanglement in discarded or lost fishing lines and abandoned nets, leads to drowning or the inability to escape predators, and ingestion of plastics can have lethal or sub-lethal effects (Coe & Rogers 1997). Sharp particles can damage the gut lining or irritate stomach tissue when ingested; resulting infections often lead to death (Kärrman et al. 2016). The presence of plastic debris in the gastrointestinal tract may reduce feeding due to perceived satiation and lead to a loss of condition and starvation (Pierce et al. 2004, Senko et al. 2020). The debris can also cause mechanical blockage or impairment of the digestive system, resulting in starvation. Some plastics are also a source of toxic pollutants, which are released into the bloodstream as the bird's digestive system attempts to break down the substance (Ryan et al.1988). The subsequent reduction in fitness can lower the bird's ability to reproduce successfully, catch prey and/or avoid predation (Fry et al. 1987, Sileo et al. 1990).
Plastics adrift in the ocean are covered in biofilm, a thin layer of microorganisms that expel dimethyl sulphide (DMS). This compound attracts albatrosses and petrels as the prey items of these birds exude the same olfactory material (Savoca et al. 2016). In consequence, seabirds are highly likely to mistake plastic particles for food and ingest them. Albatross and petrel chicks receive pollutants when they receive regurgitated food. Due to the physical impaction and internal ulceration, the chicks receive less food and nutrients which increases their chances of starvation and dehydration (Fry et al. 1987, Sileo et al. 1990).
Plastic ingestion affects some Australian albatross and petrel species (Baker et al. 2002, Gall & Thompson 2015, Roman et al. 2020). For example, analyses of 540 Shy Albatross chicks that had died 1% had plastic debris in their stomachs, ranging from segments of plastic bags to solid, coloured pieces of plastic (Hedd & Gales 2001). Black-browed, Grey-headed, Wandering Albatrosses and Southern Giant Petrels have all been observed regurgitating plastic debris to their chicks at breeding sites outside of Australia (Huin & Croxall 1996). In the southern hemisphere, plastic ingestion also affects Antipodean, Atlantic Yellow-nosed, Black-browed, Buller's, Chatham Island, Indian Yellow-nosed, Light-mantled, Northern Royal, Salvin's, Sooty, Southern Royal, Wandering and White-capped albatrosses, and Black and White-chinned petrels (Ryan 1987, Robertson 1998, Gall & Thompson 2015, Roman et al. 2020). In the waters off Australia and New Zealand, marine plastics ingestion is estimated to increase mortality in some albatross species by up to 3.4%, a level expected to lead to population declines, particularly in those populations already affected by other threats (Roman et al. 2020). It is likely that most or all other albatross and petrel species ingest plastic debris.
Microplastics can enter the food chain and can lead to secondary ingestion. For example, small plastic particles taken up by zooplankton can bioaccumulate and concentrate in higher vertebrates (Cole et al. 2013). The feeding ability of zooplankton is hampered when the guts are full of debris, and their health and function are compromised (Cole et al. 2013). It is currently not known whether toxins associated with plastics are passed through the food chain, and whether there are any potential negative effects of this transport.
Competition with fisheries for prey species
Threats from competition with fisheries for prey species.
Global captures of marine living resources are reasonably well documented. For example, in 2013, marine fisheries reported the catch of 80.9 million tonnes of fish globally (FAO 2016). Stocks fished biologically sustainably have decreased from 90% in 1974 to 69% in 2013, 58% of stocks are deemed to be fully fished, that is any increase in effort would make these fisheries no longer sustainable (FAO 2016). As the percentage of fully fished stocks has increased, the proportion of under-fished stocks has decreased (FAO 2016). Global catches vary with region—among the most productive areas is the northwest Pacific Ocean where 21.4 million tonnes (27% of global marine catch) were landed—while in comparison, in the southeast Pacific Ocean only 8.9 million tonnes (11%) were caught (FAO 2016). Illegal, unreported and unregulated (IUU) fishing activities add significantly to these numbers. For example, IUU catches are probably highest off western Africa and are responsible for 40% of total regional catches (Agnew et al. 2009). Thus, the impact on marine ecosystems is substantial and can lead to a shift in abundance of species not targeted by commercial fishers.
There is extensive overlap between areas exploited by commercial operations and seabird foraging areas (BirdLife International 2004). However, competition occurs only where commercial fishers and seabirds are targeting the same species in the same area (noting that interactions also occur between seabirds and fishing gear to scavenge catch during hauling). Intensive industrial fishing puts acute pressure on European seabirds that rely on the West African fish resources in winter (Gremillet et al. 2015).
In Australia, primary prey species for Shy Albatrosses include Redbait (Emmelichthys nitidus), Gould’s squid (Nototodarus gouldi), and Jack mackerel (Trachurus declivis) are all commercially harvested (Hedd & Gales 2001). The Fisheries Status Report relevant to these commercial species indicates they are currently 'not overfished’ in Australian waters (ABARES 2021). The ecological sustainability of fisheries should include consideration of dependent seabird species, particularly as commercial fishers target species at increasingly lower trophic levels (Pauly et al. 1998).
Many commercial fisheries target large predatory fish, such as tunas and billfishes, (Juan-Jordá et al. 2011). The removal of large numbers of predators is likely to alter the structure of marine food webs, but does not necessarily lead to a decrease in the stocks of prey fish species (Danckwerts et al. 2014). The impact on seabirds is more indirect. Large seabirds, such as albatrosses and petrels, are unable to dive to more than a few metres, but many prey species occur at depths of around 50 m. To access these fish species, many seabird species rely on subsurface predators to drive fish schools to the surface where they then become accessible to foraging seabirds (for example, Le Corre & Jaquemet 2005). Thus, as levels of commercial harvesting of large marine predatory fish species increase, seabirds are less likely to access food resources.
No albatross or petrel species within the recovery plan is presently identified as being at risk from competition with fisheries for food resources. It is difficult to determine the level (and the effects) of competition for food resources between seabird populations and fisheries (Hedd & Gales 2001) mainly because baseline data are often limited or unavailable. However, taking into account the needs of associated and dependent species is consistent with the principles of ecologically sustainable development. Exercising a precautionary approach with regard to the impact of fishing activities is needed to ensure the long-term sustainability of the marine environment.
Dependence on fisheries discards
Threats from reliance on fisheries discards.
Discards from fishing operations can alter ecosystem functions (Fondo et al. 2015). Seabirds opportunistically feed on easily available food items either discarded during commercial fishing operations or offered by tourist operators to enable tourists a better viewing opportunity. These resources, however, can affect community structures, population dynamics and the fitness of individuals (Oro et al. 2013), and may alter the manner in which seabirds use the seascape (Bartumeus et al. 2010). This is particularly the case for scavenging seabirds.
Some seabird species have become dependent upon the offal discarded from fishing vessels during operations and/or processing at sea. They scavenge dead prey and fishery discards and bait (Croxall & Prince 1994). The disposal of offal encourages albatrosses and petrels to follow fishing vessels, significantly increasing their likelihood of becoming injured or killed during fishing operations by direct interactions with fishing gear. As well, some populations have become habituated to the regular food source and appear to have altered their foraging ranges and dynamics accordingly (Ryan & Moloney 1988, Adams 1992, Blaber et al. 1998, Weimerskirch 1998, Sagar et al. 1999).
Discards are a key food resource for many seabird species (Votier et al. 2004). Black-browed Albatross foraging over the Patagonian Shelf during the non-breeding season appear to exploit fishery discards, particularly of trawlers (Mariano-Jelicich et al. 2014). The additional food obtained from commercial fishing operations may positively influence breeding success and, hence, population sizes in some seabird species (for example, Blaber et al. 1998).
Bans on discards have been introduced in various fisheries worldwide to eliminate the waste of marine resources and encourage more selective fishing (for example, Condie et al. 2014). However, cessation of discarding may have negative effects on seabird populations, at least in the short-term (Baker et al. 2002). For example, in the North Sea, discard bans, particularly when coupled with reduced availability of small shoaling pelagic fish, can result in an increase in predation by Great Skua (Catharacta skua) on other birds (Votier et al. 2004). Accordingly changes to discarding practices should be introduced gradually rather than abruptly, as scavenging seabirds are opportunistic, and a gradual reduction in the availability of discards enables them to switch prey species and habituate to a reduction in food availability (Fondo et al. 2015).
Marine tourist boat operators conducting wildlife viewing trips off the coastline of Australia and other parts of the world may throw 'chum' (such as frozen squid) to attract seabirds, particularly albatrosses, to the vessel. This technique is used to provide tourists with the opportunity to see flocks of seabirds feeding and competing at a close range. This practice offers another artificial food source for the birds, and further encourages and habituates them to follow boats which in turn increases the likelihood of seabirds interacting with fishing vessels. In many cases, ‘chumming’ is carried out by experienced birdwatchers and is considered acceptable behaviour by some parts of the birding fraternity (for example, Onley & Schofield 2007), but not by others (for example, Orams 2002). Compared to discards from commercial fishing operations, ‘chumming’ is not a significant food source for albatrosses and petrels in Australian waters.
Marine infrastructure interactions
Threats from interactions with offshore installations and ships, including artificial lighting.
Seabirds are at risk of disorientation at night from artificial light sources (Bruderer et al. 1999, Rodríguez et al. 2014, 2017). There is significant commercial, tourism, fishing, recreational vessel activity worldwide in coastal and offshore waters. Sea installations, particularly for energy extraction purposes including oil and gas, and wind farms are commonplace, particularly on continental shelf margins. Seabird interactions have been reported across the marine infrastructure sectors including vessels (Black 2005), oil and gas platforms (Wiese et al. 2001, Ronconi et al. 2015) and offshore wind farms (Dierschke et al. 2016). The response of seabirds to marine infrastructure can lead to avoidance behaviours, collisions where the bird may be killed or injured, and fallouts where the bird may be unable to return to the air without assistance (Commonwealth of Australia 2019b).
The development of offshore wind farm turbine infrastructure is an emerging issue, with offshore wind farm proposals being considered for sites along the southern Australian coastline within the foraging range of albatrosses and petrels.
Climate variability and change
Threats from climatic changes resulting in significant weather changes beyond historical variance, with effects on food dispersion and availability.
Climate change is causing major shifts in the distribution of species throughout the world (Albouy et al. 2014). Seabirds including albatrosses and petrels are susceptible to extreme climatic events (Chambers et al. 2011, 2014, Rodríguez et al. 2019). The effects of climate change on seabirds in Australian marine ecosystems include ocean warming and changes in marine currents that have the potential to affect foraging patterns due to changes in marine productivity (Thomson et al. 2015, Cleeland et al. 2019), increased frequency of storm events (Walsh & Ryan 2000, McInnes et al. 2012) and changes in wind patterns affecting the energetic cost of foraging flights (Jouventin & Weimerskirch 1990, Marshall 2003).
A major effect of climate on seabirds will be changes in prey distribution (Robinson et al. 2005), particularly during the breeding season. As the world's oceans warm, the marine environments will lose oxygen, which is likely to increase metabolic pressure on marine species (Deutsch et al. 2015), including the prey species of albatrosses and petrels. Thus, habitable zones will shrink and some species are likely leave the upper water column (0-400 m) to seek refuge lower in the water column where cool, oxygenated waters still occur. This effect is expected to be largest near the equator, but contraction of habitable zones is also expected in the mid-latitudes where many fisheries occur, particularly in the northern hemisphere. Shifts by certain species towards higher latitudes may offset the habitat loss at least partially, however this move is likely to cause increased competition for polar and subpolar species (Deutsch et al. 2015). The effect of vertical shifts in prey species in the water column in response to higher sea surface temperatures, and any consequential reduction in the availability of such prey to albatrosses and petrels is presently unknown.
How seabirds will respond to climate change and whether or not they are capable of adapting to new conditions remains largely unknown (Thompson et al. 2015), and is likely to species-specific. The effect of climate change of the marine foraging ranges of albatrosses and petrels in Australia's jurisdiction is largely unknown, and poorly studied (Cleeland et al. 2019). As well, potential climate adaption strategies are limited to intervention options that may be taken at breeding sites (for example, Alderman & Hobday 2017).

4 Recovery plan vision, objectives and strategies
4.1 Long-term vision
The populations of albatross and petrel species breeding and/or foraging in Australia’s jurisdiction have increased to such a size that each species no longer qualifies for listing as threatened under any of the Environment Protection and Biodiversity Conservation Act 1999 (Cth) listing criteria.
4.2 Recovery plan objective
The objective of the recovery plan is:
To improve the conservation status of albatrosses and petrels so that these species are on a trajectory towards no longer being threatened in Australia's jurisdiction.
The success or otherwise of the recovery plan including the trajectory of species will be measured according to progress on the plan’s strategies and overarching actions. The objective will be achieved if within three generations (60 years approx.) there is a measurable and sustained positive population trend (compared to 2021 baseline counts) in the number of mature individuals within the Australian breeding populations of albatross and petrel species within the recovery plan. The recovery plan includes strategies and overarching actions to be applied within Australia’s jurisdiction that protect albatross and petrel breeding habitats, address threats to the conservation of the species on land and at sea, generate new knowledge to guide recovery, and increase public awareness. The plan will also assist in the implementation of Australia’s international environmental responsibilities, in particular to give effect to obligations under the Agreement on the Conservation of Albatrosses and Petrels and Convention on Biological Diversity, and including engagement with relevant regional conservation and fisheries organisations and arrangements to advance the conservation of albatrosses and petrels.
4.3 Strategies to achieve the objective
While it is not expected that the recovery plan objective will be reached in full within the timeframe of this plan, the following strategies are developed for the period of this plan to focus action towards achieving the objective and long-term vision:
Ensure ongoing protection of albatross and petrel breeding sites and habitats in Australia's jurisdiction.
2. Improve the understanding of the size, structure and population trends for albatrosses and petrels breeding in Australia's jurisdiction.
3. Improve effectiveness of management measures that reduce land-based threats to albatrosses and petrels breeding in Australia's jurisdiction.
4. Improve effectiveness of management measures that reduce marine-based threats to albatrosses and petrels foraging in Australia's jurisdiction.
5. Improve understanding of generalised threats to albatrosses and petrels breeding and foraging within Australia's jurisdiction.
6. Improve community awareness of the conservation of albatrosses and petrels.
7. Achieve substantial progress towards global conservation of albatrosses and petrels in international conservation and fishing forums.
Actions identified for the recovery of albatrosses and petrels are described below. All actions apply to all species except those species-specific actions identified in Tables 6-12. While the overarching objective is long-term and is not likely be achieved prior to the scheduled five-year review of the recovery plan, or the 10-year life of the plan, indicators that may result in higher recruitment and increased population size, such as numbers of breeding birds and breeding success ascertained through monitored sites, will help to demonstrate any changes to vital rates during a shorter, five to 10-year timeframe.
5.1 Priorities assigned to each action
Priorities assigned to actions should be interpreted as follows:
Priority 1:
Taking prompt action is necessary to mitigate the key threats to albatrosses and petrels and also provide valuable information to help identify long-term population trends.
Priority 2:
Action would provide a more informed basis for the long-term management and recovery of the albatrosses and petrels.
Priority 3:
Action is desirable, but not critical to the recovery of the albatrosses and petrels or assessment of trends in that recovery.
During the life of this recovery plan new information will become available. This may include the emergence of new threats or changes in relative risk, changes in conservation status, or increased knowledge about a threat. As new information becomes available it will be taken into consideration in the context of this plan.
5.2 Overarching actions
The overarching actions in this recovery plan are designed to assess and address threats to the recovery of albatrosses and petrels in Australia's jurisdiction, and to enable and ensure the recovery of the species (Table 5). These have been devised to deliver tangible benefits to meet the recovery plan strategies. It is expected that every action will be progressed or completed during the life of this plan.

5.3 Performance of the recovery plan
The performance of this recovery plan will be considered at the completion of the plan. The performance of the plan will be rated against how successful the plan has been in meeting its overarching actions (Table 13) and will give an indication of the degree of progress towards the long-term recovery objective. The approach to reviewing performance under the Recovery Plan will be developed in consultation with the Recovery Team established under this plan, and the Threatened Species Scientific Committee. The progress of the plan will be reported at a five year (mid-term) review of the plan.
Recovery teams provide advice and assist in coordinating actions described in recovery plans. They include representatives from organisations with a direct interest in the recovery of the species, including those involved in funding and those participating in actions that support the recovery of the species. The recovery of threatened albatrosses and petrels is coordinated by the Albatross and Petrel Recovery Team that has the responsibility of providing advice, coordinating and directing the implementation of the recovery actions outlined in this recovery plan. The membership of the Recovery Team, which may change over time, currently includes individuals within relevant government agencies, the fishing industry, environmental non-government organisations, and expertise from independent researchers.
The recovery process will not be achieved prior to the scheduled five-year review or within the 10-year life of this recovery plan. A recovery plan should therefore remain in place until such time as the breeding and/or foraging populations of albatrosses and petrels in Australia's jurisdiction have improved to the point at which these species no longer meet threatened species status under the EPBC Act.
The cost of implementation of this recovery plan should be incorporated into the core business expenditure of the affected organisations and through additional funds obtained for the explicit purpose of implementing the plan. It is expected that Commonwealth and state agencies will use this plan to prioritise actions to protect the species and enhance their recovery, and that projects will be undertaken according to agency priorities and available resources. To maximise the conservation outcomes and cost effectiveness of this plan, it is intended that the recovery actions proposed complement, where possible, those of other protected matters.
The summary of cost estimates against each strategy shown in Table 14 below are provided for guidance and do not represent funding commitments.
Table 14: Summary of recovery actions and estimated costs for the first five years of implementation (these estimated costs do not take into account inflation over time).
TOTAL $1090,000 $1,090,000 $1,090,000 $2,590,000 $1,140,000 $7,000,000
* The increase in estimated expenditure in Year 4 under Strategy 2 is associated with an anticipated management visit to Heard Island.
8 Effects on other native species and biodiversity benefits
Reducing marine and terrestrial anthropogenic impacts affecting threatened albatrosses and petrels will likely benefit seabirds generally including other listed threatened, migratory and marine species over time, particularly:
storm petrel species within the Family Oceanitidae and Family Hydrobatidae
petrel, fulmar, prion, shearwater, and diving petrel species within the Family Procellariidae
gannet species within the Family Fregatidae
skua species within the Family Stercorariidae
penguin species within the Family Spheniscidae.
Many of these species breed at the same locations and/or forage across similar ranges as the albatross and petrel species included in this recovery plan (Parks and Wildlife Service 2006, Commonwealth of Australia 2014, 2018a, 2018b). Implementation of the plan will also have positive outcomes for other marine and coastal species and listed ecological communities through improving habitat quality.
9 Social and economic considerations
This recovery plan is not linked directly to any Australian Government funding programs. However, the plan helps direct the focus of government funding programs to activities that will help to meet identified actions. While the Australian Government is unable to provide funding to cover all actions in this plan, it is committed to implement the plan to the extent to which it applies in Commonwealth areas. Investment in addressing the threats to the conservation of albatrosses and petrels will be further determined by the level of resources that the fishing industry, government and non-government stakeholders are also able to commit to implementation of the actions under the plan.
The successful implementation of the actions under this recovery plan will rely on support from stakeholders. Partnerships involving the fishing industry, government and non-government organisations, universities, community groups and Indigenous groups will be key to successfully delivering the actions under the plan.
The plan does not of itself impose any economic burdens on fishers, rather it supports the implementation of related threat abatement plans (Commonwealth of Australia 2018a, 2018b) and the NPOA-Seabirds (DAWR 2018). However, the imposition of technical and operational mitigation measures may have financial impacts on fishers. These may be partially offset, for example, if measures to avoid or minimise interactions with seabirds result in a market advantage for fish marketed as being caught in a manner that avoids seabird bycatch.
While wildlife tourism attracts many visitors (Higginbottom 2004), with bird watching activities among seabird colonies being particularly attractive tourist destinations (for example, Yorio et al. 2001), this activity along with recreational boating and fishing may disturb albatrosses and petrels at their breeding sites, as well as foraging birds adjacent to these locations. Restrictions on access to albatross and petrel breeding sites in Australia have been in place under previous recovery plans and do not generally impact landowners, land managers and developers. Albatrosses and petrels are found on remote, offshore island locations, and access to individual albatross and petrel populations is restricted by significant logistical difficulties. These sites are, therefore, relatively less attractive for ecotourism and other visitation, when compared to mainland bird colonies. Biosecurity protocols applying to research activities helps minimise the risk of introduction of pest species, and thereby avoid the need for future pest eradication programs, as was necessary to eradicate cats, rabbits, rats and mice from Macquarie Island (Robinson & Copson 2014, Alderman et al. 2019).
There is potential for social benefits to flow from community members engaging in citizen science concerning albatrosses and petrels. For example, a small, dedicated group has been conducting routine surveys of offshore seabird abundance in New South Wales waters for nearly 20 years (Gorta et al. 2019). This citizen science provides a long-term data set that has helped to assess whether the abundance of particular albatross and petrel populations foraging off south-eastern Australia has changed over time.
Many marine species have cultural significance to Aboriginal and Torres Strait Islander people. There is some evidence from Aboriginal language and history of a link to albatross and their breeding habitat in Tasmania. The Tasmanian Aboriginal people of the north-west region called Albatross Island tangatema and they may have visited the island by canoe in calm conditions when the journey between Hunter and Albatross Islands could be safely negotiated (Wastell et al. 2015) and the island has also been referred to as namanu rruni (Alderman 2018, pers. comm., 5 September 2018).
Organisations likely to be affected by the actions proposed in this recovery plan include: international multilateral and bilateral agreements, government agencies (Commonwealth and state), particularly those involved with environmental protection, conservation and fisheries management programs, the fishing industry, Indigenous community groups, researchers, and conservation groups. This list however should not be considered exhaustive, as there may be other interest groups that would like to be included in the future or need to be considered when specialised tasks are required.
Table 15 lists some of the interest groups, how they could contribute to the success of the recovery plan and the potential benefits/impacts that may emerge from the plan’s implementation.

Any comments received that were relevant to the recovery of threatened albatrosses and petrels were considered by the Threatened Species Scientific Committee as part of the development of this plan.
12 Organisations/persons involved in evaluating performance of the plan
Section 279 of the EPBC Act provides for the review of action under a recovery plan at any time and requires that each plan be reviewed at intervals no greater than five years from when it was endorsed and made publicly available. The review of this recovery plan will determine the performance of the plan and will be coordinated by the Department of Climate Change, Energy, the Environment and Water in association with relevant Australian and state government agencies, and key stakeholder groups, such as the fishing industry, environmental non-governmental organisations, research organisations, and Indigenous interest groups. The review will examine action under the plan and assess progress towards achieving the plan's objective. The review’s recommendations will form the basis of a revised plan, if required.
Key stakeholders who may be involved in the review of the performance of the recovery plan, include organisations likely to be affected by the actions proposed in this plan and are expected to include:
Australian Government
Australian Fisheries Management Authority Department of Climate Change, Energy, the Environment and Water Threatened Species Commissioner Threatened Species Scientific Committee
State governments
Department of Biodiversity, Conservation and Attractions (WA) Department of Environment and Water (SA) Department of Environment, Land, Water and Planning (Vic) Department of Natural Resources and Environment (Tas) Department of Planning and Environment (NSW) Department of Environment and Science (Qld)
Fishing industry
Representative groups, and individual fishers and companies operating in Commonwealth and State-managed commercial and recreational fisheries.
Non-government organisations
Antarctic and Southern Ocean Coalition Australasian Seabird Group BirdLife Australia Humane Society International World Wide Fund for Nature
Indigenous interest groups
Tasmanian Aboriginal Centre
Institutions
Universities and other research organisations
Regular annual meetings of the newly established Recovery Team will help ensure that progress is monitored and implementation of the recovery plan is progressed.

Within each grouping albatross species profiles are provided before those for petrels.
Albatross species breeding in Australia's jurisdiction
Diomedea exulans Linnaeus 1758 is accepted nomenclature for the Wandering Albatross. Originally Diomedea exulans Linnaeus 1758. There has been considerable debate about the taxonomy for wandering-type albatrosses and whether these should be split into subspecies or recognised at the specific level (ACAP 2012v). Robertson & Nunn (1998) recognised Diomedea exulans at the specific level based on the species’ morphology and genetics, with this nomenclature widely accepted (ACAP 2012v).
Current status of taxon

Life history
Breeding locality Jurisdiction
Macquarie Island Australia
Crozet Islands, Kerguelen Islands France
Marion Island, Prince Edward Island South Africa
South Georgia/Islas Georgia del Sur Other
There are 28 breeding sites for the Wandering Albatross that occur on sub-Antarctic island groups of Australia (Macquarie Island), France (Crozet Islands, Kerguelen Islands), South Africa (Marion Island, Prince Edward Island), and other (South Georgia/Islas Georgias del Sur) (ACAP 2012v). The Wandering Albatross is a biennial breeder, when successful, but about 30% of successful and 35% of failed breeders defer breeding beyond the expected year (Croxall et al. 1998). Adults begin arriving at colonies from November. Females lay a single egg in December/January that hatches after a mean incubation period of 11 weeks in February/April (Tickell 2000). The chick remains in the nest for another 9-10 months during which time it may build a new nest for itself, with most chicks fledging in December (Croxall et al. 1990, Tickell 2000). Mean annual breeding success varies between 69-75% annually (Weimerskirch et al. 1997, Croxall et al. 1998, Nel et al.2002). The Wandering Albatross is highly dispersive in all the southern oceans. Juveniles return to breeding colonies between 3-14 years of age, with individuals potentially beginning breeding when 7-10 years of age (Weimerskirch & Jouventin 1987, Pickering 1989, Weimerskirch 1992, Croxall et al. 1998). Generation length is estimated at 22.9 years (Bird et al. 2020).
The Wandering Albatross is present in a very small population of 3-13 breeding pairs on Macquarie Island. Breeding success averages 62.1% ± 3.4% over a 27-year monitoring period. There is a moderate decline in breeding effort -3.17% ± 0.92% over the 27-year period, with an uncertain trend of 0.77 ± 4.44% over the last 10 years (DPIPWE 2021a).
Wandering Albatross mostly feed during daylight (Harper 1987, Phalan et al. 2007). Birds may form large groups (~50 birds) at rich food sources including behind fishing vessels and are voracious scavengers, out-competing all other seabirds for fishing discards and baited hooks (Weimerskirch et al. 1986, Brothers 1991). Birds seize most prey by surface seizing, surface diving to about one metre and rare shallow plunging (Harper 1987, Prince et al. 1994a). Wandering Albatross diet is composed mainly of fish and cephalopod species, with small amounts of other prey (for example, crustaceans and jellyfish) and scavenged species (for example penguins) (Croxall et al. 1988, Cherel & Klages 1998, van den Hoff 2001, Xavier et al. 2003b).
Foraging areas of the Wandering Albatross may vary due to sexual and age-related segregation (BirdLife International 2004). For example, during the breeding season at Crozet Island females forage in subtropical waters to the north of the colony, while males prefer colder, higher latitude waters (Weimerskirch 1995). In non-breeding years, individuals also appear to have a preferred home range, 1500-8500 km from the island, with a similar sexual segregation, females in warmer water than males (Weimerskirch & Wilson 2000).
On dispersal from the colony, juvenile birds frequent subtropical waters of the Indian Ocean and Tasman Sea where wind velocity and productivity are both low; these regions are typically not used by adult birds (Weimerskirch et al. 2006). Breeding adults from Macquarie Island are known to forage in distant oceanic waters over 2000 km away from the island, while non-breeding birds are known to forage in waters north of the island, including New Zealand shelf waters (de la Mare & Kerry 1994, Terauds et al. 2006b). Foraging effort by Wandering Albatross appears to be related to energy acquisition per unit effort, so that food intake levels remain stable, with flight costs the lowest recorded for any seabird (Schaffer et al. 2001).
Species distribution in Australia
The Wandering Albatross nests on Macquarie Island (Figure 1). The species is highly dispersive in all the southern oceans from the edge of the pack ice (68°S), north to at least the Tropic of Capricorn and sometimes beyond. The species’ range approaches 10°S along the western coasts of South America and Africa, and vagrants have been seen off California and in the northern Atlantic. In winter, birds are frequently found north of the Antarctic Convergence (Blakers et al. 1984, Nicholls et al. 1995, 1997, 2000). Comparisons of results of satellite tracking has revealed that distances and patterns of dispersal are variable between breeding stages and populations (BirdLife International 2004, ACAP 2012v). Recent research on the genetic diversity of Wandering Albatross on Macquarie Island has highlighted haplotypes that match Diomedea exulans from a range of breeding sites across their range (McInnes 2021, pers. comm., 15 December 2021). There were also haplotypes detected that closely match those from Diomedea antipodensis (Antipodean Albatross). Further research is needed to determine genetic provenance of these animals.
The Wandering Albatross population on Macquarie Island may have always been small compared to large populations on other similar sized islands (Selkirk et al. 1990). However, circumstantial evidence suggests that Wandering Albatross may have once been numerous on the Island, as seal and penguin oil harvesters that occupied Macquarie Island from 1810 to 1920 used Wandering Albatross as a source of food (Cumpston 1968, Townrow 1988). By the time the Australasian Antarctic Expedition surveyed Macquarie Island in 1913, only one Wandering Albatross pair was left breeding. Once harvesting ceased, the population gradually increased to around 25 breeding pairs by the mid-1960s before declining again (Carrick & Ingham 1970, Terauds et al. 2006b). Macquarie Island may represent marginal habitat for the species because the continental shelf around Macquarie Island is relatively smaller than that adjacent to other sub-Antarctic islands (Selkirk et al. 1990).
A small population of Wandering Albatross may still be present on Heard Island (Kirkwood et al. 1989). A Wandering Albatross pair was brooding a small chick on Heard Island in 1980 (Johnstone 1982). The male had been banded as a non-breeding adult on Macquarie Island in 1967, but the female was not seen. Two old nest mounds found nearby suggests there may have been breeding attempts at the site in previous years.
Population estimates and trends
The breeding population of Wandering Albatross on Macquarie Island is experiencing a moderate decline based on a TRIM analysis (Pannekoek & van Strien 2006) over the last 10 years (DPIPWE 2021a).
Globally, the population trend indicates a population decline for the species exceeding 30% over three generations (BirdLife International 2018e). There were an estimated 9400 breeding pairs in 2021 (ACAP 2022).
Habitat critical to survival of species
Macquarie Island is included on the register of critical habitat for Wandering Albatross under the EPBC Act. The species is limited to 28 breeding sites in Australia (Macquarie Island), France (Crozet Islands, Kerguelen Islands), South Africa (Marion Island, Prince Edward Island), and other (South Georgia/as Georgias del Sur), with the largest population on the Crozet Islands (ACAP 2012v).

Phoebetria palbebrata (Forster 1785) is accepted nomenclature for the Light-mantled Albatross. Originally Diomedea palbebrata Forster 1785. The genus Phoebetria was introduced by Reichenbach (1852) and a review by Nichols & Murphy (1914) included the Light-mantled Albatross within that genus as Phoebetria palbebrata. Genetic analyses support this nomenclature (Robertson & Nunn 1998, Nunn et al. 1996) with the nomenclature widely accepted (ACAP 2012m).

Species description
A small-medium albatross, the Light-mantled Albatross is approximately 78-90 cm in length, 2.6-3.7 kg in weight, with a wing length of 49-55 cm, and bill length of 98-117 mm (ACAP 2015, Menkhorst et al. 2017). Tubenosed; separate nostrils on a large, black plated bill with bluish bill stripe on lower mandible. Combination of dark and paler grey plumage, except for partial white ring to eye, with head, wings and tail dark, while body paler grey, with slender wings and wedge-pointed tail (Onley & Scofield 2007, BirdLife International 2018i).
There are 71 breeding sites for the Light-mantled Albatross that occur on island groups of Australia (Heard Island, McDonald Islands, Macquarie Island), France (Crozet Islands, Kerguelen Islands), New Zealand (Antipodes Islands, Auckland Islands, Campbell Islands), South Africa (Marion Island, Prince Edward Island), and other (South Georgia/Islas Georgias del Sur) (ACAP 2012m). The Light- mantled Albatross is predominantly a biennial breeder, when successful (Jouventin & Weimerskirch 1988, Croxall & Gales 1998). Adults arrive at colonies from early October to mid-September. Females lay a single egg from October/November that hatches after incubation period of 9-10 weeks in December/January (Berruti 1979, DPIPWE 2021a). Fledging of chicks occurs after approximately 4-5 months in May/June (Berruti 1979). Mean annual breeding success varies by location from 15-47% (ACAP 2012m). Light-mantled Albatross fledge one chick, on average, every five years, consequently, this species has one of the lowest reproduction rates for any species of albatross (Weimerskirch et al. 1987). The Light-mantled Albatross has a wide circumpolar range across the southern oceans. Juveniles return to breeding colonies after 7-12 years (Weimerskirch et al. 1987). Generation length is estimated at 21.4 years (Bird et al. 2020).
Light-mantled Albatross feed during the day and at night (Phalan et al. 2007). Birds take prey by surface seizing and plunge diving (Harper 1987). Individual birds may dive to an average of 5 m (with some individuals diving to more than 12 m in pursuit of prey) (Prince et al. 1994a, Harper 1987). Light-mantled Albatrosses do not follow fishing vessels as frequently as other species (Cherel & Klages 1998). Light-mantled Albatross diet is comprised of cephalopods, fish, crustaceans and carrion (including other seabirds) (Cherel & Klages 1998, Green et al. 1998).
Breeding adults forage great distances with Light-mantled Albatrosses breeding at Macquarie Island commonly seen over open waters south and west of Tasmania (Reid et al. 2002). Individuals form Macquarie Island forage up to 2200 km from their nest (Weimerskirch & Robertson 1994). Similarly large foraging ranges have been found at other breeding sites for the species (Akkers 2002, Phillips et al. 2005). Little known about the foraging strategies of Light-mantled Albatross outside the breeding season. The species has a wide, circumpolar range throughout the Southern Ocean and in winter are regular visitors to the pelagic waters of south and south-east Australia (Marchant & Higgins 1990).
Species distribution in Australia
Light-mantled Albatrosses nest on Heard Island, McDonald Islands and Macquarie Island. An indicative distribution map is not available for this non-threatened species. Tracking studies indicate that dispersal is generally between 40-60°S in southern oceans, but may extend to between 20-77°S, and includes southern and sub-Antarctic Australia (Marchant & Higgins 1990, BirdLife International 2004, ACAP 2012m). Birds breeding on Macquarie Island foraged an average 1516 km from the island in sub-Antarctic and Antarctic waters (Weimerskirch & Robertson 1994), however very little is known about the foraging strategies of the Light-mantled Albatross outside the breeding season. The size of the breeding populations of Light-mantled Albatross on Heard Island, McDonald Islands and Macquarie Island before human visitation is unknown. Harvesting of eggs and/or birds may have occurred during the 19th Century while the islands were occupied by sealers (Cumpston 1968, Townrow 1988, Downes 2002).
An island-wide census of the breeding population of Light-mantled Albatross on Macquarie Island was last conducted in 2013 with 2150 ± 300 breeding pairs recorded, with the population currently monitored at three study sites with 79 (67-131) breeding pairs recorded in 2019-20 (DPIPWE 2021a). The population breeding on Heard Island has not been systematically surveyed since 1954 when it was estimated there were 200-500 breeding pairs on the island (Downes et al. 1959), with a later estimate of 500 breeding pairs (minimum) (Woehler 2006). A small population was recorded on McDonald Islands (Johnstone 1980), but its current size is unknown. Visits to McDonald Islands are not permitted, as the location is subject to intermittent volcanic activity (Stephenson et al. 2005, Commonwealth of Australia 2014).
Population estimates and trends
The breeding population of Light-mantled Albatross on Macquarie Island is experiencing a moderate decline based on a TRIM (TRends and Indices for Monitoring data) analysis (Pannekoek & van Strien 2006) over the past 10 years (DPIPWE 2021a), with no estimates available for Heard Island and McDonald Islands.
Global estimates of population change over three generations for the species are subject to considerable uncertainty, due to an absence of comprehensive studies of all breeding populations, with a moderately rapid population decline suspected to be taking place over 100 years (BirdLife International 2018i). There were an estimated 15,900 breeding pairs in 2021, but this figure excluded uncertain estimates of 5000 breeding pairs from the Auckland Islands (ACAP 2022).
Habitat critical to survival of species
Heard Island and McDonald Islands, and Macquarie Island, are subject to management plans that protect these listed world heritage sites and adjacent marine reserves (Parks and Wildlife Service 2006, Commonwealth of Australia 2014). All three breeding populations of Light-mantled Albatross in Australia’s jurisdiction are likely to be important for the long-term persistence of the species within Australia.
The species is limited to 71 breeding sites in Australia (Heard Island, McDonald Islands, Macquarie Island), France (Crozet Islands, Kerguelen Islands), New Zealand (Antipodes Islands, Auckland Islands, Campbell Islands), South Africa (Marion Island, Prince Edward Island), and other (South Georgia/Islas Georgias del Sur), with the largest population at South Georgia/Islas Georgias del Sur (ACAP 2012m).

Thalassarche cauta Shy Albatross (Gould 1841)
Family: Diomedeidae
Taxonomy
Thalassarche cauta (Gould 1841) is accepted nomenclature for the Shy Albatross (ACAP 2012q). There has been significant taxonomic debate about the classification of Diomedeidae including, but not limited to, the introduction of the genus Thalassarche by Reichenbach (1852). Originally Diomedea cauta Gould 1841. The Shy Albatross was considered polytypic until it was included in the resurrected genus Thalassarche (Reichenbach 1852) and elevated to the specific level as Thalassarche cauta based on morphological and demographic differences, and genetic analyses (Nunn et al. 1996, Robertson & Nunn 1998). ACAP has concluded on advice from its Taxonomy Working Group that available data warrant recognition of Shy Albatross at the specific level with the nomenclature generally accepted (Double 2006, ACAP 2012q, TSSC 2020).
Current status of taxon
Environment Protection and Biodiversity Conservation Act 1999 (Commonwealth): Endangered

Species description
A medium albatross, the Shy Albatross is approximately 90-110 cm in length, 3.2-5.1 kg in weight, with a wing length of 53-59 cm, and bill length of 122-138 mm (ACAP 2015, Menkhorst et al. 2017). Tubenosed; separate nostrils on a large, pale grey-yellow plated bill with yellowish upper ridge, with yellow tip and yellow at base of bill. Combination of black, grey and white plumage, white head with grey sides and dark eyebrow, white body with black upper wings, black margins and a dark tab intruding into the base of the underwings, and grey-black tail, (Onley & Scofield 2007, BirdLife International 2018p).
Life history
Breeding locality
Jurisdiction
Albatross Island, Mewstone, Pedra Branca
Australia
Endemic to Australia with three breeding sites on three Tasmanian islands (Albatross Island, Mewstone, Pedra Branca) (ACAP 2012q). The Shy Albatross is an annual breeder, when successful. Birds are present at the colonies year-round with females laying a single egg predominantly in September, with chicks hatching after 10 weeks in December. Fledging commences when the birds are about four and a half months old in April, although there are minor variations between colonies (Abbott et al. 2006b). Mean annual breeding success averages 43% on Albatross Island with data not available for the other breeding sites (DPIPWE 2021b). The Shy Albatross disperses in the higher latitudes of the Indian Ocean and south-west Atlantic Ocean. Juveniles begin returning to colonies when three years of age, and commence breeding when at least 5-6 years of age, with an average breeding age of nine years (Brothers et al. 1998, Hedd & Gales 2005, Alderman 2012). Generation length is estimated at 20.6 years (Bird et al. 2020).
Shy Albatross usually forage singly or in flocks (~20 birds) (Barton 1979). Birds will also aggregate behind fishing vessels where they are usually able to out-compete all smaller Procellariiformes, all but the great albatrosses (Brothers 1991). Shy albatrosses take fish from surface schools flight feeding, and other prey by surface feeding and surface diving (Barton 1979, Harper et al. 1985, Croxall & Prince 1994). Diving activity occurs mostly during daylight (from 7 am to 10 pm), with the deepest dives (over 7 m) occurring from 10 am to noon (Hedd et al. 1997). Shy Albatross diet is composed mostly of fish and cephalopods, with small amounts of tunicates and crustaceans (Hedd & Gales 2001, McInnes et al. 2020). Prey selection appears to be relatively constant across seasons and years (Hedd & Gales 2001, McInnes et al. 2020). Although natural prey comprises the main diet, scavenging behind fishing vessels is significant food source for a significant proportion of birds (13% generally and up to 29% during some breeding phases) (McInnes et al. 2020).
Shy albatrosses are less oceanic than many other albatross species, are usually found over the continental shelf, and regularly venture close to shore along the coasts of Tasmania and southern Australia (Brothers et al. 1998, Hedd et al. 2001, Reid et al. 2002). The range also extends to southern Africa and into the southern Atlantic Ocean (Barton 1979, Blakers et al. 1984, Tickell 1995, Reid et al. 2002, BirdLife International 2004, Abbott et al. 2006a, Jiménez et al. 2015). During the breeding season, adults forage close to their colonies, usually within 300 km in continental shelf waters (Hedd et al. 2001). Sub-adult dispersal appears to be colony specific with birds from Albatross Island remaining in southern Australian waters, and some birds from the Mewstone dispersing between South Africa and New Zealand, noting that there are no records of immature birds banded at Pedra Branca being recovered away from that colony (Brothers et al. 1997).
Species distribution in Australia
The Shy Albatross only nests on Albatross Island, the Mewstone and Pedra Branca off Tasmania (Figure 2). Tracking studies, band recoveries and genetic identification of Shy Albatross bycaught during fishing operations indicate that adult birds predominantly occur in waters adjacent to Tasmania and southern Australia (Brothers et al. 1997, Abbott et al. 2006a). The range of juvenile birds extends however across the Indian Ocean to southern Africa and potentially the south-western Atlantic Ocean (Barton 1979, Alderman 2012, Jiménez et al. 2015).
Significant harvesting of adult Shy Albatross for their feathers and eggs occurred at Albatross Island during the 1800s with the subpopulation declining from about 20,000 birds to about 300 birds by the end of that century, with the population slowly recovering since then (Green 1974, Johnstone et al. 1975, Brooke 2004).
Shy Albatross is subject to ongoing long-term monitoring on Albatross Island, with aerial surveys used for the Mewstone and Pedra Branca, as access to these locations is restricted for logistical and safety reasons. The number of breeding pairs in 2019/20 was estimated at 5385 (4910-5947) on Albatross Island and 81 (± 1) on Pedra Branca, with around 10,000 (± 200) pairs estimated on the Mewstone in 2014/15 (DPIPWE 2021b).
Population estimates and trends
The breeding population of Shy Albatross is considered stable on Albatross Island based on a TRIM analysis (Pannekoek & van Strien 2006) over the past 10 years, at the Mewstone the trend is uncertain, with Pedra Branca experiencing a steep decline over the same period (DPIPWE 2021b). Population models predict a decline in the number of breeding females in the Albatross Island subpopulation over three generations, but discrepancies exist between the predictions and the most recent empirical data, meaning there is uncertainty around the extent of the decline (TSSC 2020). There is a predicted decline in the Pedra Branca subpopulation linked to interspecies competition with the Australasian Gannet and storm surges (Alderman et al. 2011, Alderman 2018, ACAP 2012q, TSSC 2020). There were an estimated 15,000 breeding pairs in 2021 (ACAP 2022).
Eligibility for listing in the Endangered category under the EPBC Act reflects the restricted area of occupancy of the species; the precarious geographic distribution for the survival of the species, because its number of locations is restricted; a projected decline in the number of mature individuals for the Albatross Island subpopulation, and inferred declines for the Pedra Banca and Mewstone subpopulations. Inclusion of the Shy Albatross in the IUCN Red List Near Threatened category reflects the lack of negative trend data for the larger Mewstone population, which would enable the species to achieve qualification to a higher conservation status. The Action Plan for Australian Birds 2020 (Garnett & Baker 2021) highlights that there is need for further empirical data to confirm whether and to what extent the Shy Albatross population is declining.
Habitat critical to survival of species
The Tasmanian islands of Albatross Island, the Mewstone and Pedra Branca are included on the register of critical habitat for Shy Albatross under the EPBC Act. The species is limited to these three breeding sites in Australia, with the largest population on the Mewstone (ACAP 2012q).

Thalassarche chrysostoma (Forster 1785) is accepted nomenclature for the Grey-headed Albatross. There has been significant taxonomic debate about the classification of Diomedeidae including, but not limited to, the introduction of the genus Thalassarche by Reichenbach (1852). Originally Diomedea chrysostoma Forster 1785. The Grey-headed Albatross was included in the resurrected genus Thalassarche (Reichenbach 1852) as Thalassarche chrysostoma based on demographic differences and genetic analyses (Nunn et al. 1996, Robertson & Nunn 1998) with the nomenclature widely accepted (ACAP 2012j).

There are 29 breeding sites for the Grey-headed Albatross that occur on island groups of Australia (Macquarie Island), Chile (Islas Diego Ramirez, Islas Ildefonso), France (Crozet Islands, Kerguelen Islands), New Zealand (Campbell Island), South Africa (Prince Edward Islands), and other (South Georgia/Islas Georgias del Sur) (ACAP 2012j). The Grey-headed Albatross is predominantly a biennial breeder, when successful (Ryan et al. 2007). Adults arrive at colonies from early September to early October (Weimerskirch et al. 1986, Brooke 2004, Terauds et al. 2005). Females lay a single egg in October that hatches after incubation period of 10 weeks in December (Weimerskirch et al. 1986, Terauds et al. 2005, DPIPWE 2021a). Fledging of chicks occurs after approximately 4-5 months in late April/May (Tickell & Pinder 1975, Weimerskirch et al. 1986, Terauds et al. 2005, DPIPWE 2021a). Mean annual breeding success varies by location from 34-72% (ACAP 2012j). The Grey-headed Albatross has a wide circumpolar range across the southern oceans. Juveniles return to breeding colonies after at least three years and commence breeding on average between 7-13 years depending on location (ACAP 2012j). Generation length is estimated at 22.7 years (Bird et al. 2020).
Grey-headed Albatross take most prey by surface-seizing and surface-plunging (Wood 1992, Prince et al. 1994a). Birds can dive to at least 6 m and remain swimming below the surface for up to 11 seconds in search of prey (Prince et al. 1994a). Diet is composed mostly of fish and cephalopods, with small amounts of other species (Waugh et al. 2000, Cherel et al. 2002, Xavier et al 2003a, 2003b).
Foraging areas of the Grey-headed Albatross may vary due to sexual segregation (Phillips et al. 2004). During the breeding period adults will travel hundreds or thousands of kilometres from the colony, generally to forage waters within or south of the Antarctic Polar Frontal Zone (Prince et al. 1998, Weimerskirch et al. 1988). Grey-headed albatrosses breeding at Macquarie Island typically forage in waters south of the island, frequently travelling into the Southern Ocean (BirdLife International 2004, Terauds et al. 2006a). Non-breeding adults and immature birds disperse widely over the Southern Ocean and may exhibit a circumpolar winter distribution (Croxall et al. 2005). The Grey-headed Albatross is a regular visitor to Australia and New Zealand, especially in winter, particularly south and west of Tasmania (Blakers et al. 1984, Reid et al. 2002).
Species distribution in Australia
The Grey-headed Albatross nests on Macquarie Island (Figure 3). Tracking studies indicate that dispersal is circumpolar in higher latitudes in southern oceans between 35-65°S including southern and sub-Antarctic Australia, and the AAT (Weimerskirch et al. 1986, Weimerskirch et al. 1988, BirdLife International 2004, ACAP 2012j). A more northerly distribution between 39-51°S is apparent during the austral winter (Marchant & Higgins 1990).
Birds breeding on Macquarie Island predominantly forage in sub-Antarctic and Antarctic waters south of the island (Terauds et al. 2006a), however very little is known about the foraging strategies of Grey Albatross outside the breeding season. The size of the breeding populations of Grey-headed Albatross on Macquarie Island before human visitation is unknown. Harvesting of eggs and/or birds may have occurred during the 19th century while the island was occupied by sealers (Cumpston 1968, Townrow 1988). An island-wide census of the breeding population of Grey-headed Albatross on Macquarie Island was conducted in 2019/20 with 113 (58-114) breeding pairs recorded (DPIPWE 2021a).
Population estimates and trends
The breeding population of Grey-headed Albatross on Macquarie Island is experiencing a moderate increase based on a TRIM analysis (Pannekoek & van Strien 2006) over the past 10 years (DPIPWE 2021a).
Globally, the population is experiencing a very rapid decline over three generations (BirdLife International 2018r). There were an estimated 80,850 breeding pairs in 2020 (ACAP 2022).
Habitat critical to survival of species
Macquarie Island is included on the register of critical habitat for the Grey-headed Albatross under the EPBC Act. The species is limited to 29 breeding sites that occur on island groups of Australia (Macquarie Island), Chile (Islas Diego Ramirez, Islas Ildefonso), France (Crozet Islands, Kerguelen Islands), New Zealand (Campbell Island), South Africa (Prince Edward Islands), and other (South Georgia/Islas Georgias del Sur), with the largest population on South Georgia/as Georgias del Sur (ACAP 2012j).

There are 69 breeding sites for the Black-browed Albatross that occur on island groups of Australia (Heard Island, McDonald Islands, Macquarie Island), Chile (Isla Diego de Almagro, Islas Diego Ramirez, Islas Ildefonso, Isolete Albatross, Isloete Leonard, Islotes Evangelistas) France (Crozet Islands, Kerguelen Islands), New Zealand (Antipodes Islands, Auckland Islands, Campbell Islands), and other (Falkland Islands/Islas Malvinas, South Georgia/Islas Georgias del Sur) (ACAP 2012d). The Black-browed Albatross is an annual breeder when successful, with a significant level of non-breeding in the subsequent year for successful (25%) and unsuccessful breeders (23%) (Croxall et al. 1998). The breeding cycle varies by location. For example, adults arrive at Macquarie Island from early September, with females laying a single egg from late September/October that hatches after incubation period of 9-10 weeks in December/January, with fledging of chicks occurring after approximately 4 months in April/May (Terauds et al. 2005). Mean annual breeding success varies by location from 27-66%, depending on location (ACAP 2012d). The Black-browed Albatross has a wide circumpolar range across the southern oceans. Juveniles return to breeding colonies after at least two years with breeding commencing when birds are 8-10 years of age (Prince et al. 1994b). Generation length is estimated at 23.6 years (Bird et al. 2020).
Black-browed Albatross take most prey by surface-seizing and surface-plunging and pursuit diving, and are frequent fishing vessel followers. Some individuals are capable of remaining submerged for over 50 seconds in pursuit of prey (Guilford et al. 2022). Individual birds reach a maximum depth of 19 m while foraging (Guilford et al. 2022). All individuals dived to more than one metre, indicating that diving is a common mode of capturing prey (Harper 1987, Guilford et al. 2022). Black-browed Albatross diet is composed mostly of fish, cephalopods, jellyfish and scavenged species, with small amounts of other species (Cherel et al. 2002, Xavier et al. 2003a, 2003b, McInnes et al. 2017). For example, at the Kerguelen Islands Black-browed Albatross forage on cephalopods, fish and penguins in roughly equal proportions (Cherel et al. 2002). The diet of fish species includes species discarded from fishing operations, with the presence of fish hooks and fish bait species indicating a strong association with fisheries in southern Chile, Falkland Islands/Islas Malvinas and Kerguelen Islands (Arata & Xavier 2003, McInnes et al. 2017b).
Foraging areas of Black-browed Albatross are extensive with birds accessing Antarctic and sub-Antarctic shelf waters proximate to their breeding islands during the breeding season, but ranging widely when not breeding and favouring the warmer coastal or shelf waters of Australia, New Zealand, South Africa and South America (Weimerskirch et al. 1985, 1986). Black-browed Albatross in Australia’s jurisdiction forage along the southern coastline from Perth to Brisbane (Blakers et al. 1984, Marchant & Higgins 1990, Reid et al. 2002). Sub-adults remain in Australian waters all year round with immature birds forming the preponderance (99%) of Black-browed Albatross seen in south-eastern Australian waters between October and January (Reid et al. 2002).
Species distribution in Australia
Black-browed Albatross nests on Heard Island, McDonald Islands and Macquarie Island (including Bishop and Clerk Islets) (Figure 4). Tracking studies indicate that dispersal is circumpolar from subtropical waters to the Antarctic ice-edge and includes southern and sub-Antarctic Australia, and the AAT (BirdLife International 2004, Terauds et al. 2005, ACAP 2012d), with birds breeding on Macquarie Island generally foraging in the adjacent exclusive economic zone (Terauds et al. 2006a).
The size of the breeding populations of Black-browed Albatross on Heard Island, McDonald Islands and Macquarie Island before human visitation is unknown. Harvesting of eggs and/or birds may have occurred during the 19th Century while the islands were occupied by sealers (Cumpston 1968, Townrow 1988, Downes 2002). Black-browed Albatross is subject to ongoing long-term monitoring on Macquarie Island with 47 (range 42-49) breeding pairs estimated in 2019/20, with long-term breeding success averaging 45% (DPIPWE 2021a). The population breeding on Heard Island has not been systematically surveyed since 2000 when there were around 600 breeding pairs on the island (Woehler et al. 2002). The population on McDonald Islands was last estimated in 1981 when 82-89 breeding pairs were recorded (Keage & Johnstone 1982). Visits to McDonald Islands are not permitted, as the location is subject to intermittent volcanic activity (Stephenson et al. 2005, Commonwealth of Australia 2014). Bishop and Clerk Islets have only been visited on three occasions with 141 active nests identified on Bishop Islet when the site was last visited in 1993 (Brothers & Ledingham 2008).
Population estimates and trends
The breeding population of Black-browed Albatross on Macquarie Island is considered stable based on a TRIM analysis (Pannekoek & van Strien 2006) over the past 10 years (DPIPWE 2021a), with no estimates available for Bishop and Clerk Islets, Heard Island and McDonald Islands.
Globally, the population appears to be increasing over three generations (BirdLife International 2018u). There were an estimated 689,400 breeding pairs in 2020 (ACAP 2022).
Habitat critical to survival of species
Heard Island and McDonald Islands, and Macquarie Island, are subject to management plans that protect these listed world heritage sites and adjacent marine reserves (Parks and Wildlife Service 2006, Commonwealth of Australia 2014). All breeding populations of Black-browed Albatross in Australia’s jurisdiction are likely to be important for the long-term persistence of the species within Australia. The species is limited to 65 breeding sites in Australia (Heard Island, McDonald Islands, Macquarie Island), Chile (Isla Diego de Almagro, Islas Diego Ramirez, Islas Ildefonso, Islote Albatross, Islote Leonard, Islotes Evangelistas) France (Crozet Islands, Kerguelen Islands), New Zealand (Antipodes Islands, Auckland Islands, Campbell Islands), and other (Falkland Islands/as Malvinas), South Georgia/Islas Georgias del Sur), with the largest population at the Falkland Islands/Islas Malvinas) (ACAP 2012d).

There are 193 breeding sites for the Southern Giant Petrel that occur in Antarctica (Adélie Land, Antarctic Peninsula, South Orkney Islands, South Shetland Islands), and on island groups of Argentina (Isla Arce, Isla de los Estados, Isla Gran Robredo, Isla Observatorio), Australia (AAT, Heard Island, McDonald Islands, Macquarie Island), Chile (Isla Noir, Islas Diego Ramirez), France (Crozet Islands, Kerguelen Islands), South Africa (Prince Edward Islands), and United Kingdom (Gough Island), and other (Falkland Islands/Islas Malvinas, South Georgia/Islas Georgias del Sur, South Sandwich Islands/Islas Sandwich del Sur) (ACAP 2012s). The majority of the Southern Giant Petrel population breeds annually, however a significant proportion (20-40%) of non-breeding is evident each year during ‘sabbatical’ periods that average 1.4 years (Voisin 1988). The start of the breeding cycle varies by location. For example, adults arrive at Macquarie Island in August/September, with females laying a single egg from late August to early September that hatches after incubation period of about 9 weeks in October to mid-November, with fledging of chicks occurring after approximately 4 months from late January to late March (Patterson et al. 2008, DPIPWE 2021a). Mean annual breeding success varies by location depending on location, with breeding success estimated at 50 ± 10% on Macquarie Island (ACAP 2012s, DPIPWE 2021a). The Southern Giant Petrel has a wide circumpolar range across the southern oceans including Antarctica. Juveniles return to Macquarie Island to commence breeding when birds are 9-11 years of age (Woehler & Johnstone 1988). Generation length is estimated at 20.6 years (Bird et al. 2020).
Southern Giant Petrel forage at sea, and also scavenge on land. Birds take prey at sea by surface seizing, surface filtering, surface diving, and surface plunging (Harper 1987). Individual birds may dive up to 3 metres in pursuit of prey or carrion (Harper 1987, van den Hoff & Newbery 2006). They are aggressive opportunists scavenging prey from other smaller birds (Harper et al. 1985, Harper 1987). During breeding periods Southern Giant Petrel prey mainly on cephalopods and fish at sea, and also prey on penguin chicks on land and scavenge seal or penguin carrion (Harper 1987, Le Bohec et al. 2003). Incidents of depredation of adult Atlantic Yellow-nosed Albatross have been reported from Gough Island (Risi et al. 2021).
Southern Giant Petrel range widely throughout the southern oceans with foraging areas varying due to sexual segregation (Patterson & Hunter 1999, Patterson et al. 2008, Trebilco et al. 2008). Foraging range of breeding adults may vary markedly. At Macquarie Island, during the incubation stage adults undertook long trips of up to 19 days south of Macquarie Island, often covering thousands of kilometres to areas south of the Antarctic Circumpolar Current (Trebilco et al. 2008). As the chicks hatched, the length of the foraging trips decreased and birds spent more time close to Macquarie Island. Throughout the colder months, immature birds and most adults disperse widely. Some adults are mainly sedentary, remaining close to their breeding islands throughout the year. Nonetheless, numbers diminish at all sites over winter, with the Antarctic colonies being almost completely abandoned. The waters off south-east Australia may be particularly important wintering grounds with most Southern Giant Petrel (over 80%) sighted off south-east Australia being immature birds (Marchant & Higgins 1990, Reid et al. 2002).
Species distribution in Australia
Southern Giant Petrel nests on Heard Island, McDonald Islands and Macquarie Island, as well as in the AAT (Figure 5). Tracking and banding studies indicate that dispersal is circumpolar from the Tropic of Capricorn to Antarctica and includes southern and sub-Antarctic Australia, and the AAT (BirdLife International 2004, van den Hoff 2011, ACAP 2012s). During the breeding cycle, birds on Macquarie Island generally forage southwards to the Antarctic ice edge or eastwards to South America (Patterson & Hunter 1999, Trebilco et al. 2008).
The size of the breeding populations of Southern Giant Petrel on Heard Island, McDonald Island and Macquarie Island before human visitation is unknown. Harvesting of eggs and/or birds may have occurred during the 19th Century while the islands were occupied by sealers (Cumpston 1968, Townrow 1988, Downes 2002). Southern Giant Petrel is subject to ongoing long-term monitoring on Macquarie Island with the number of breeding pairs estimated to be between 1450-2180 pairs in 2019/20 based on estimated numbers of pre-fledging chicks, and long-term breeding success estimated at 50 ± 10% (DPIPWE 2021a). The population breeding on Heard Island has not been systematically surveyed since 1988 when there were around 3150 breeding pairs on the island (Kirkwood et al. 1995). The population on McDonald Island was last estimated in 1979 when around 1400 breeding pairs were recorded (DSEWPC 2011b). Visits to McDonald Islands are not permitted, as the location is subject to intermittent volcanic activity (Stephenson et al. 2005, Commonwealth of Australia 2014).
Southern Giant Petrel colonies are found in the AAT: 237 breeding pairs were estimated at the Frazier Islands, Wilkes Land in 2011 (ATCM 2013), four occupied nests occurred at Giganteus Island, Mac.Robertson Land in 2007 (ATCM 2015), and about 23 breeding pairs were estimated at Hawker Island, Princess Elizabeth Land in 2014 (ATCM 2016).
Population estimates and trends
The breeding population of Southern Giant Petrel on Macquarie Island is considered stable based on a TRIM analysis (Pannekoek & van Strien 2006) over the past 10 years (DPIPWE 2021a), with no estimates available for Heard Island and McDonald Islands or for breeding sites within the AAT.
Globally, the population trend appears variable at between a 17% increase to a 7% decline in the global population over three generations (BirdLife International 2018g). There were an estimated 46,100 breeding pairs in 2021 (ACAP 2022).
Habitat critical to survival of species
Heard Island and McDonald Islands, and Macquarie Island, are subject to management plans that protect these listed world heritage sites and adjacent marine reserves (Parks and Wildlife Service 2006, Commonwealth of Australia 2014). The Antarctic breeding sites are all located in designated Antarctic Specially Protected Areas and subject to management plans (ATCM 2013, 2015, 2016). All breeding populations of Southern Giant Petrel in Australia’s jurisdiction are likely to be important for the long-term persistence of the species within Australia.
The species occupies 193 breeding sites in Antarctica (Adélie Land, Antarctic Peninsula, South Orkney Islands, South Shetland Islands) and on island groups of Argentina (Isla Arce, Isla de los Estados, Isla Gran Robredo, Isla Observatorio), Australia (AAT, Heard Island, McDonald Islands, Macquarie Island), Chile (Isla Noir, Islas Diego Ramirez), France (Crozet Islands, Kerguelen Islands), South Africa (Prince Edward Islands), United Kingdom (Gough Island), and other (Falkland Islands/as Malvinas, South Georgia/Islas Georgias del Sur, South Sandwich Islands/Islas Sandwich del Sur), with the largest population at the Falkland Islands/Islas Malvinas (ACAP 2012s).

There are 50 breeding sites for the Northern Giant Petrel that occur on island groups of Australia (Macquarie Island), France (Crozet Islands, Kerguelen Islands), New Zealand (Antipodes Islands, Auckland Islands, Chatham Islands, Campbell Island) South Africa (Prince Edward Islands), and other (South Georgia/Islas Georgias del Sur) (ACAP 2012n). The majority of the Northern Giant Petrel population breeds annually, however a significant proportion (15-40%) of non-breeding is evident each year during ‘sabbatical’ periods that average 2.7 years (Bourne & Warham 1966, Voisin 1988). Adults arrive at colonies in August with females laying a single egg in August to early October that hatches after incubation period of about 9 weeks from October to early December with fledging of chicks occurring after approximately 4 months from late January to late March (Patterson et al. 2008, DPIPWE 2021a). Mean annual breeding success varies by location, with breeding success estimated at 62% on Macquarie Island (ACAP 2012n, DPIPWE 2021a). The Northern Giant Petrel has a wide circumpolar range across the southern oceans. Juveniles return to commence breeding when birds are 4-11 years of age (Voisin 1988). Generation length is estimated at 17.1 years (Bird et al. 2020).
Northern Giant Petrel are diurnal feeders at sea that also scavenge on land during the day and at night (Le Bohec et al. 2003). Birds take prey at sea by surface seizing, surface filtering, surface diving, and surface plunging up to 2 m in pursuit of prey (Harper 1987). They are aggressive opportunists scavenging prey from other smaller birds (Harper et al. 1985, Harper 1987). Females are smaller than males (80% by weight) with both sexes scavenging on seal and penguin carrion, and predating albatross chicks (González-Solis 2004, Dilley et al. 2013). During breeding periods, females also feed extensively on other marine food resources and show more pelagic habits than males (González-Solis 2004).
Northern Giant Petrel disperse widely throughout the southern oceans, mainly north of the Antarctic Convergence (Patterson & Hunter 1999, Patterson et al. 2008, Trebilco et al. 2008). At Macquarie Island most breeding birds forage within 100 km of the island (Trebilco et al. 2008). In winter, birds from Macquarie Island are found as far as southern Africa and South America and are frequently observed in southern Australian waters (Marchant & Higgins 1990, Reid et al. 2002, Trebilco et al. 2008).
Species distribution in Australia
Northern Giant Petrel nests on Macquarie Island (Figure 6). Tracking and banding studies indicate that dispersal is circumpolar, predominantly between 30-64°S and includes southern and sub-Antarctic Australia, however records at sea are subject to misidentification between the giant petrel species (Voisin 1988, BirdLife International 2004, ACAP 2012n). During the breeding cycle birds breeding on Macquarie Island generally forage southwards to the Antarctic ice edge or eastwards to South America (Trebilco et al. 2008).
The size of the breeding population of Northern Giant Petrel on Macquarie Island before human visitation is unknown. Harvesting of eggs and/or birds may have occurred during the 19th Century while the island was occupied by sealers (Cumpston 1968, Townrow 1988). Northern Giant Petrel is subject to ongoing long-term monitoring on Macquarie Island. An island-wide census of the breeding population on Macquarie Island was last conducted in 2013/14 with 1490 breeding pairs recorded, with the population currently monitored at a representative study site with 337 (248-391) annual breeding pairs recorded in 2019/20, and long-term breeding success estimated at 62% (DPIPWE 2021a).
Population estimates and trends
The breeding population of Northern Giant Petrel on Macquarie Island is considered uncertain based on a TRIM analysis (Pannekoek & van Strien 2006) over the past 10 years (DPIPWE 2021a), which is attributed to the impact of secondary poisoning in 2011 during work to eradicate pest species from the island (Parks & Wildlife Service 2014, DPIPWE 2021a).
Globally, the population appears to be increasing (BirdLife International 2017). There were an estimated 11,550 breeding pairs in 2021 (ACAP 2022).
Habitat critical to survival of species
Macquarie Island is subject to a management plan that protects this listed world heritage site and adjacent marine reserves (Parks and Wildlife Service 2006). The breeding population of Northern Giant Petrel in Australia’s jurisdiction is likely to be important for the long-term persistence of the species within Australia. The species is limited to 50 breeding sites on island groups of Australia (Macquarie Island), France (Crozet Islands, Kerguelen Islands), New Zealand (Antipodes Islands, Auckland Islands, Chatham Islands, Campbell Island) South Africa (Prince Edward Islands), and other (South Georgia/Islas Georgias del Sur), with the largest population at South Georgia/Islas Georgias del Sur (ACAP 2012n).

There are 17 breeding sites for the Grey Petrel that occur on island groups of Australia (Macquarie Island), France (Amsterdam Island, Crozet Islands, Kerguelen Islands), New Zealand (Antipodes Islands, Campbell Island), South Africa (Prince Edward Islands), and United Kingdom (Gough Island, Tristan da Cunha) (ACAP 2012i). The Grey Petrel is an annual winter breeder when successful (Jouventin et al. 1985, Chastel 1995). The breeding biology is variable with adults arriving at colonies from early February with females laying a single egg from late March to early April that hatches after incubation period of 7-9 weeks from late May to early June, with fledging of chicks occurring after 4-5 months from August to early December (Jouventin et al. 1985, Zotier 1990). Mean annual breeding success varies by location from 13-45% at sites outside the Australia’s jurisdiction (ACAP 2012i), while breeding success at Macquarie Island has consistently been ≥75% since rodent and rabbit eradication in 2012-2014 (Bird et al. in review, DPIPWE 2021a).
The Grey Petrel has a wide circumpolar range across the southern oceans and subtropical South America. Juveniles return to commence breeding when birds are an average of seven years of age (Barbraud et al. 2009). Generation length is estimated at 16.9 years (Bird et al. 2020).
Grey Petrel mostly forage alone, but may be found in small groups (around a dozen birds) including around fishing vessels and cetaceans (Harper 1987). Birds take prey by surface seizing and deep plunge diving (Harper 1987). Grey Petrel forage during daylight and return to their burrows at night. Adult birds usually depart burrows before dawn and return at dusk, with a few birds return to breeding colonies during the day (Bell et al. 2013). Grey Petrel diet is comprised mostly of cephalopods and fish and crustaceans and includes offal and discards from fishing vessels (Ridoux 1994).
Grey petrels range widely throughout the southern oceans with foraging areas demonstrating sexual segregation. During the breeding season females forage further north than males, in waters north of the Subtropical Convergence, over 1400 km from breeding sites (Bartle 1990). Grey Petrel re-established a breeding population on Macquarie Island after an 80-year absence (Schultz et al. 2005). After the breeding season, birds disperse widely.
Species distribution in Australia
The Grey Petrel breeds at Macquarie Island. An indicative distribution map is not available for this non-threatened species. Tracking studies indicate that dispersal is predominantly circumpolar between 32-58°S, extending to 18°S on the west coast of South America, and including southern and sub-Antarctic Australia (Marchant & Higgins 1990, BirdLife International 2004, ACAP 2012i).
The size of the breeding population of Grey Petrel on Macquarie Island before human visitation is unknown with the current population based on recolonization after an absence of some 80 years (to 2000) (Schultz et al. 2005). The extirpation was believed to be due to predation of this burrowing petrel species by feral cat (Felis catus) (Jones 1980). Grey Petrel monitoring has recommenced on Macquarie Island with an island-wide census of the breeding population undertaken in 2018, however population demographics are not yet available (DPIPWE 2021a). The latest population estimate, derived from an island-wide survey in 2018, is 252 (95% CI 227-302) breeding pairs (Bird et al. 2021a, 2021b, DPIPWE 2021a).
Population estimates and trends
While there is no population trend information available for the species over three generations due to a lack of data, the global population is suspected to be moderately rapidly declining (BirdLife International 2018k). There were an estimated 86,900 breeding pairs in 2018, however this estimate did not including the population on the Prince Edward Islands (ACAP 2022).
Habitat critical to survival of species

Diomedea amsterdamensis Amsterdam Albatross Roux et al. 1983
Family: Diomedeidae
Taxonomy
Diomedea amsterdamensis Roux et al. 1983 is accepted nomenclature for the Amsterdam Albatross. There has been considerable debate about the taxonomy for the wandering-type albatrosses (ACAP 2012a). Originally Diomedea exulans Linnaeus 1758. A review undertaken by Roux et al. (1983) recommended raising to specific level, based on the species’ adult plumage patterns, morphology and breeding biology (ACAP 2012a).

Species description
A large albatross, the Amsterdam Albatross is approximately 100-110 cm in length, 4.8-8.0 kg in weight, with a wing length of 62-68 cm, and bill length of 138-156 mm (ACAP 2015, Menkhorst et al. 2017). Tubenosed; separate nostrils on a large, pink plated bill with greenish tip, and distinctive dark cutting edge. Eye with white eyelid. Combination of white and brown plumage, with mostly dark brown upperparts, with variable white on neck and back, with face and underparts mostly white, except for brown wingtips, with variable brown breast band (Onley & Scofield 2007, BirdLife International 2018a). Very similar in plumage to Wandering Albatross.
Life history
Breeding locality
Jurisdiction
Amsterdam Island
France
Endemic to the Amsterdam Island (France) with one breeding site on the island. The Amsterdam Albatross is a biennial breeder, when successful. On average, each breeding pair produces one egg every 1.8 years and fledges a chick every 2.4 years (Jouventin et al. 1989). Adult birds begin arriving at Amsterdam Island in January. Females lay a single egg in late February/March that hatches after an incubation period of over 11 weeks in May. The chicks fledge in January/February after spending at least eight months in the nest (Jouventin et al. 1989). Mean annual breeding success was estimated at 72% (Weimerskirch et al. 1997). The offspring then range the oceans for 4-7 years before returning to the island. Individuals do not begin breeding until they are nine years of age. Generation length is estimated at 22.3 years (Bird et al. 2020).
Species distribution in Australia
Australia is within the foraging range of the Amsterdam Albatross (Figure 7). The pelagic range for this species is poorly known, because of the similar appearance to other albatross species, such as the Wandering Albatross. Most sightings have been of birds in the Indian Ocean, with tracking studies indicating that adults forage generally within 2000 km of Amsterdam Island during the breeding season, while juveniles disperse across the Indian Ocean including adjacent to southwest Western Australia and eastern Africa (BirdLife International 2004, ACAP 2012a).
Population estimates and trends
The current global population trend is increasing (BirdLife International 2018a). Although numbers have been increasing since the late 1990s, the species remains among the world’s rarest seabirds (BirdLife International 2018a). There were an estimated 50 breeding pairs in 2020 (ACAP 2022).
Habitat critical to survival of species
Species is limited to one breeding site on Amsterdam Island (France) in the southern Indian Ocean.

Diomedea antipodensis Antipodean Albatross Robertson and Warham 1992
Family: Diomedeidae
Taxonomy
Diomedea antipodensis Robertson and Warham 1992 nomenclature remains under debate for the Antipodean Albatross (Double 2006, ACAP 2012b). Originally Diomedea exulans Linnaeus 1758. There has been considerable debate about the taxonomy for the wandering-type albatrosses (ACAP 2012b). Diomedea antipodensis is listed under the EPBC Act at the specific level, with Diomedea antipodensis gibsoni (Gibson’s Albatross) listed as a subspecies. Robertson & Warham (1992) proposed the nomenclature Diomedea exulans antipodensis (and Diomedea exulans gibsoni). The species was recommended to be raised to specific level by Robertson & Nunn (1998) as Diomedea antipodensis and Diomedea gibsoni based on the species’ morphology and ecology, with ACAP concluding on advice from its Taxonomy Working Group that available data do not warrant the recognition of Antipodean and Gibson’s albatrosses as separate species (Double 2006, ACAP 2006).

Breeding locality
Jurisdiction
Antipodes Islands, Auckland Islands, Campbell Island
New Zealand
Endemic to New Zealand with six breeding sites on the sub-Antarctic Antipodes Islands, Auckland Islands and Campbell Island. The Antipodean Albatross is a biennial breeder, when successful. The breeding season varies by a few weeks between the islands, commencing on the Auckland Islands, then on the Antipodes Islands and later on Campbell Island. Adults begin arriving at colonies from December/January. Females lay a single egg in late December/February that hatches after an incubation period of over 11 weeks in March/April (Walker & Elliott 1999, 2005). The chicks fledge after nine months, in late December to early March in the following year (Robertson 1985, Marchant & Higgins 1990, Brooke 2004; Walker et al. 2017). Mean annual breeding success has been averaged at 63% annually (Walker and Elliott 1999, Walker & Elliott 2002). Antipodean Albatross disperse over the Tasman Sea and South Pacific Ocean (Marchant & Higgins 1990). Juveniles return to the breeding colonies when three years of age and individuals do not begin breeding until they are seven years of age. Generation length is estimated at 25.9 years (Bird et al. 2020).
Species distribution in Australia
Australia is within the foraging range of the Antipodean Albatross (Figure 8). Tracking studies indicate that the birds from the Antipodes Islands mostly forage in the Pacific Ocean east of New Zealand, and the range of non-breeding birds is larger than that of breeders (BirdLife International 2004, Walker & Elliott 2006, ACAP 2012b). Non-breeding males have the largest range, foraging off the coast of Chile, Antarctica and in the tropical South Pacific. Birds from the Auckland Islands use differing foraging strategies according to sex, with females tending to frequent the Tasman Sea in the vicinity of 40°S, while males either disperse westwards at lower latitudes or travel north-east towards the mid-Pacific Ocean (Elliot et al. 1995). Non-breeding male and female birds forage westwards to the south-eastern Indian Ocean, including southern and sub-Antarctic Australia (BirdLife International 2004, Walker & Elliott 2006, ACAP 2012b).
Population estimates and trends
Projected very rapid population decline of the global population over three generations (BirdLife International 2018b). A dramatic population crash occurred at the Antipodes Islands in 2005, and adult males from this breeding population have been declining annually at 6% and females at 12% (Walker & Elliott 2017). The decline appears in large part due to very high female mortality, in some years up to 20%, though reduced breeding success and increased recruitment age have exacerbated the problem (Elliot & Walker 2020). There were an estimated 7100 breeding pairs in 2020 (ACAP 2022).
Habitat critical to survival of species
Species is limited to six breeding sites in New Zealand on the Antipodes Islands, Auckland Islands and Campbell Island, with the largest colony on Antipodes Island (ACAP 2012b).

Diomedea dabbenena Matthews 1929 is accepted nomenclature for the Tristan Albatross. Diomedea dabbenena was first recognised as a separate species by Mathews (1929), being sister taxon to Diomedea exulans Linnaeus 1758. There has been considerable debate about the taxonomy for the wandering-type albatrosses (ACAP 2012u). Taxonomic deliberations led to a proposed complex of subspecies including Diomedea exulans dabbenena with the Tristan Albatross later raised to the specific level, based on the species’ genetics, morphology and other character differences (Gales 1998, Robertson & Nunn 1998, Cuthbert et al. 2003a), with this nomenclature now widely accepted (ACAP 2012u).

Tristan de Cunha
United Kingdom
Endemic to Tristan de Cunha (United Kingdom) with two breeding sites on Gough Island, and Inaccessible Island (ACAP 2012u, McClelland et al. 2016). The Tristan Albatross is a biennial breeder, when successful. Adults begin arriving at colonies from November. Females lay a single egg in January that hatches after an incubation period of over two months in March/April. The chicks fledge after eight to nine months, in November to January in the following year (Cuthbert et al. 2004). Mean annual breeding success is declining, averaging 32% in 2007 (Wanless 2007), but reported as just over 9% in 2014 (Davis et al. 2015). The range of the Tristan Albatross extends over the southern Atlantic and Indian Oceans to southern Australia (Marchant & Higgins 1990). Juveniles return to the breeding colonies when 3-7 years of age and individuals begin breeding at a mean age of 10 years (Wanless 2007). Generation length is estimated at 21.2 years (Bird et al. 2020).
Species distribution in Australia
Australia is within the foraging range of the Tristan Albatross (Figure 9). Tracking studies indicate that during the breeding season the birds mostly forage in the southern Atlantic Ocean, but disperse more widely during non-breeding periods including across the Indian Ocean to south-western Australia (BirdLife International 2004, ACAP 2012u).
Population estimates and trends
Projected extremely rapid population decline of the global population over three generations (BirdLife International 2018c). There is presently very low adult survival (BirdLife International 2018c). There were an estimated 1450 breeding pairs in 2017 (ACAP 2022).
Habitat critical to survival of species
Species is limited to two islands in Tristan de Cunha (United Kingdom) on Gough Island and Inaccessible Island in the southern Atlantic Ocean.

New Zealand
Endemic to New Zealand with four breeding sites in the sub-Antarctic Auckland Islands, and Campbell Island (ACAP 2012t). The Southern Royal Albatross is a biennial breeder, when successful. Adults begin arriving at colonies from October. Females lay a single egg from late November to late December that hatches after an incubation period of 10-12 weeks in early February to early March (Waugh et al. 1997). The chicks fledge after seven to eight months, in early October to early November (Marchant & Higgins 1990). Mean annual breeding success varies between 62-77% annually (Waugh et al. 1997, Moore et al. 1997, Childerhouse et al. 2003). The Southern Royal Albatross has a circumpolar range in the higher latitudes of the southern hemisphere (30-55°S) (BirdLife International 2004, 2018d). Juveniles return to breeding colonies when 3-7 years of age, with individuals beginning breeding when 6-12 years of age (Marchant & Higgins 1990, Childerhouse et al. 2003, Wanless 2007). Generation length is estimated at 27.9 years (Bird et al. 2020).
Species distribution in Australia
Australia is within the foraging range of the Southern Royal Albatross (Figure 10). Tracking studies indicate that during the breeding season the birds mostly forage in New Zealand waters, but dispersal is circumpolar during non-breeding periods, including southern, sub-Antarctic Australia, and the AAT (BirdLife International 2004, ACAP 2012t).

Auckland Islands, Chatham Islands, South Island of New Zealand (at Taiaroa Head)
New Zealand
Endemic to New Zealand with five breeding sites on the sub-Antarctic Chatham Islands and Auckland Islands, and at Taiaroa Head on the South Island of New Zealand (ACAP 2012t). The Northern Royal Albatross is a biennial breeder, when successful. Adults begin arriving at colonies from August to mid-November. Females lay a single egg in late October to early November that hatches after an incubation period of over 11 weeks in late January to early February, with the chicks mostly fledging in September/October after spending at least eight months in the nest (Tickell 2000). The Northern Royal Albatross has a circumpolar distribution in the higher latitudes of the southern hemisphere (generally 36-52°S) (BirdLife International 2004, 2018f). Mean annual breeding success at Taiaroa Head was estimated as 31% (Westerskov 1963 in Marchant & Higgins 1990). Juveniles return to breeding colonies when at least three years of age, with individuals usually beginning breeding when eight years of age (Robertson 1993, 1998). Generation length is estimated at 26.0 years (Bird et al. 2020).
Species distribution in Australia
Australia is within the foraging range of the Northern Royal Albatross (Figure 11). Tracking studies indicate that during the breeding season the birds mostly forage in New Zealand waters, but dispersal is circumpolar during non-breeding periods, including southern and sub-Antarctic Australia, and AAT (BirdLife International 2004, ACAP 2012o).
Population estimates and trends
The global population is projected to be decreasing over three generations with uncertainty about the extent of the projected decline (BirdLife International 2018f). There were an estimated 4080 breeding pairs in 2018 (ACAP 2022).
Habitat critical to survival of species
Species is limited to five breeding sites in New Zealand, on the Auckland Islands, Chatham Islands, Campbell Island, and Taiaroa Head on the South Island of New Zealand in the south-western Pacific Ocean, with the global population predominantly found on the Chatham Islands (ACAP 2012o).

Phoebetria fusca (Hilsenberg 1822) is accepted nomenclature for the Sooty Albatross. Originally Diomedea fusca Hilsenberg 1822. The genus Phoebetria was introduced by Reichenbach (1852) and a review by Nichols & Murphy (1914) included the Sooty Albatross within the genus as Phoebetria fusca. Genetic analyses support this nomenclature (Robertson & Nunn 1998, Nunn et al. 1996) with the nomenclature widely accepted (ACAP 2012r).

There are 15 breeding sites for the Sooty Albatross that occur on island groups of France (Amsterdam Island, Crozet Islands, Kerguelen Islands, Saint Paul Island), South Africa (Marion Island, Prince Edward Island), and Tristan de Cunha (United Kingdom) (ACAP 2012r). The Sooty Albatross is predominantly a biennial breeder, when successful (Ryan 2007). Adults mostly arrive at colonies in August/September. Females lay a single egg from mid-September to late October that hatches after incubation period of 9-10 weeks in mid-December (Berruti 1979, Weimerskirch et al. 1986). Fledging of chicks occurs after approximately 4-6 months in May-June (Berruti 1979, Weimerskirch et al. 1986, 1987). Annual breeding success estimated for one site varied significantly, averaging 58% (range 10-85%) (Weimerskirch & Jouventin 1998). The Sooty Albatross disperses widely in the southern Atlantic Ocean and southern Indian Ocean. Juveniles return to breeding colonies when eight years old, and begin beginning breeding at an average age of 12 years of age (Weimerskirch et al. 1987). Generation length is estimated at 21.1 years (Bird et al. 2020).
Species distribution in Australia
Australia is within the foraging range of the Sooty Albatross (Figure 12). Tracking studies indicate that dispersal is generally between 30-60°S in the southern Atlantic Ocean and southern Indian Ocean, but may extend to between 10-65°S, and includes southern and sub-Antarctic Australia (Tickell 2000, BirdLife International 2004, ACAP 2012r).
Population estimates and trends
The global population is experiencing a very rapid decline over three generations, but there is uncertainty about the trend due to variability between population counts (BirdLife International 2018h). There were an estimated 12,000 breeding pairs in 2021 (ACAP 2022).
Habitat critical to survival of species

Thalassarche bulleri (Rothschild 1893) nomenclature for Buller’s Albatross remains under debate (Double 2006, ACAP 2012f). There has been significant taxonomic debate about the classification of Diomedeidae including, but not limited to, the introduction of the genus Thalassarche by Reichenbach (1852). Originally Diomedea bulleri Rothschild 1893 and Diomedea platei Reichenow 1898, with the latter later considered by Murphy (1936) as a juvenile plumage phase of the former. Buller’s Albatross was included in the resurrected genus Thalassarche (Reichenbach 1852) at the specific level based on genetic analyses (Nunn et al. 1996). Thalassarche bulleri is listed under the EPBC Act at the specific level, with Thalassarche bulleri platei (Northern Buller’s Albatross) listed as a subspecies. Robertson & Nunn (1998) suggested Thalassarche bulleri and Thalassarche platei as distinct terminal taxa based on morphological differences. ACAP has concluded on advice from its Taxonomy Working Group that available data did not warrant the recognition of Buller’s and Pacific albatrosses as separate species (Double 2006, ACAP 2006).

New Zealand
Endemic to New Zealand with 10 breeding sites on the Chatham Islands, Solander Islands, Snares Islands, and Three Kings Islands (ACAP 2012f). Buller’s Albatross is typically an annual breeder with the breeding cycle at the Snares and Solander Islands commencing about three months later than at the Chatham and Three Kings Islands. Adults arrive at the Snares and Solander Islands in mid-December. Females lay a single egg in January/February that hatches after incubation period of around nine weeks in mid-March to April (Sagar & Warham 1998). Fledging of chicks occurs after approximately five and a half months in August to October (Warham & Bennington 1983, Sagar & Warham 1998). At the Chatham Islands, eggs are laid in November, hatch in January and chicks fledge in June (Robertson 1985, 1991). Mean annual breeding success varies by location from 51-71% (Sagar et al. 2002). Buller’s Albatross ranges across the southern Pacific Ocean and western seaboard of South America. Juveniles begin returning to colonies after at least three years, and commence breeding on average when 10-11 years of age (Francis & Sagar 2012). Generation length is estimated at 19.6 years (Bird et al. 2020).
Species distribution in Australia
Australia is within the foraging range of Buller’s Albatross (Figure 13). Tracking studies and at-sea studies indicate that dispersal from the breeding colonies is generally in the higher latitudes of the Pacific Ocean, but may extend northwards along the west coast of South America to the equator, and includes south-eastern Australia (Stahl et al. 1998, BirdLife International 2004, ACAP 2012b).
Population estimates and trends
The global population is considered stable and there are no projections of decline over three generations (BirdLife International 2018n). There were an estimated 33,200 breeding pairs in 2019 (ACAP 2022).

Thalassarche carteri Indian Yellow-nosed Albatross (Rothschild 1903)
Family: Diomedeidae
Taxonomy
Thalassarche carteri (Rothschild 1903) is accepted nomenclature for the Indian Yellow-nosed Albatross (Robertson 2002, ACAP 2012k). There has been significant taxonomic debate about the classification of Diomedeidae including, but not limited to, the introduction of the genus Thalassarche by Reichenbach (1852). Originally Thalassogeron carteri Rothschild 1903, within the genus Thalassogeron that had been introduced by Baird et al. (1884). Thalassogeron carteri was considered distinct from Thalassogeron chlororhynchos Gmelin 1789, the nomenclature for the Atlantic Yellow-nosed Albatross at that time (Rothschild 1903). The Indian Yellow-nosed Albatross was included in the resurrected genus Thalassarche (Reichenbach 1852) at the specific level as Thalassarche carteri based on genetic analyses (Nunn et al. 1996, Robertson & Nunn 1998).

Fledging of chicks occurs after approximately four months in March/April (Robertson & van Tets 1982, Miskelly et al. 2001). Mean annual breeding success unknown (ACAP 2012p). Salvin’s Albatross disperses in the higher latitudes of the Pacific Ocean. It is not known when juveniles first return to colonies or when they begin breeding (ACAP 2012p). Generation length is estimated at 19.2 years (Bird et al. 2020).
Species distribution in Australia
Australia is within the foraging range of Salvin's Albatross (Figure 17). At-sea records indicate that dispersal from the breeding colonies is generally in the higher latitudes of the Pacific Ocean including includes waters adjacent to southern and eastern, and sub-Antarctic Australia (BirdLife International 2004, ACAP 2012p).
Population estimates and trends
There is no global population trend information available for the species over three generations (BirdLife International 2018v). There were an estimated 26,450 breeding pairs in 2019 (ACAP 2022).
Habitat critical to survival of species
The species is limited to 12 breeding sites on the Bounty Islands and Snares Islands (New Zealand), with the largest population at the Bounty Islands (ACAP 2012p).
Threats

Thalassarche steadi Falla 1933 is generally accepted nomenclature for the White-capped Albatross. There has been significant taxonomic debate about the classification of Diomedeidae including, but not limited to, the introduction of the genus Thalassarche by Reichenbach (1852). Originally Thalassarche cauta steadi Falla 1933. The White-capped Albatross was considered polytypic until it was included in the resurrected genus Thalassarche (Reichenbach 1852) at the specific level as Thalassarche salvini based on morphology and demographic differences, and genetic analyses (Robertson & Nunn 1998). ACAP has concluded on advice from its Taxonomy Working Group that available data warrant recognition of the White-capped Albatross at the specific level with the nomenclature generally accepted (Double 2006, ACAP 2012x).

Jurisdiction
Auckland Islands, Antipodes Islands
New Zealand
Endemic to New Zealand with five breeding sites on the Auckland Islands, and Antipodes Islands (ACAP 2012x). The breeding cycle for the White-capped Albatross has not been fully described. The species exhibits an intermediate breeding strategy, with 63% breeding in one year, and 78% of failed breeders breeding in the next year (Francis 2012). Adults may be present at colonies year-round, with females laying a single egg in mid-November to mid-December that hatches after 9-10 weeks in mid-January to mid-February (Sagar 2017). Fledging of chicks occurs after approximately four months in June (Thompson et al. 2009). White-capped Albatross disperses in the higher latitudes of the southern hemisphere. It is not known when juveniles first return to colonies or when they begin breeding (ACAP 2012x). Generation length is estimated at 19.2 years (Bird et al. 2020).
Species distribution in Australia
Australia is within the foraging range of the White-capped Albatross (Figure 18). Tracking studies indicate that dispersal from the breeding colonies is generally in the higher latitudes of the southern hemisphere including waters adjacent to south-eastern Australia, particularly north-east of Tasmania (BirdLife International 2004, ACAP 2012x). At sea records are problematic due to similarities between, and overlapping range of White-capped Albatross and Shy Albatross (Abbott et al. 2006a).
Population estimates and trends
There is no global population trend information available for the species over three generations (BirdLife International 2018w). There were an estimated 62,900 breeding pairs in 2017 (ACAP 2022).
Habitat critical to survival of species
The species is limited to five breeding sites on the Auckland Islands, and Antipodes Islands (New Zealand), with the largest population on Disappointment Island in the Auckland Islands (ACAP 2012x).

Falkland Islands/Islas Malvinas, South Georgia/Islas Georgias del Sur
Other
There are 73 breeding sites for the White-chinned Petrel that occur on island groups of France (Crozet Islands, Kerguelen Islands), New Zealand (Antipodes Islands, Auckland Islands, Campbell Islands), South Africa (Prince Edward Islands), and other (Falkland Islands/Islas Malvinas, South Georgia/Islas Georgias del Sur) (ACAP 2012y). The White-chinned Petrel is an annual breeder when successful (Jouventin et al. 1985, Hall 1987). Adults arrive at colonies from September with females laying a single egg from mid-October to mid-November that hatches after incubation period of 8 weeks from mid-December to mid-January with fledging of chicks occurring after approximately 3 months in March/April (Jouventin et al. 1985, Hall 1987). Mean annual breeding success varies by location from 21-51% (ACAP 2012y). The White-chinned Petrel has a wide circumpolar range across the southern oceans and subtropical South America. Juveniles return to commence breeding when birds are 4-9 years of age (ACAP 2012y). Generation length is estimated at 18.6 years (Bird et al. 2020).
Species distribution in Australia
Australia is within the foraging range of the White-chinned Petrel. An indicative distribution map is not available for this non-threatened species. Tracking studies indicate that while dispersal is circumpolar, and includes southern and sub-Antarctic Australia, most birds within Australia’s jurisdiction come from New Zealand populations (BirdLife International 2004, Rexer-Huber 2017).
Population estimates and trends
While there is no global population trend information available for the species over three generations due to a lack of data, the population is considered to be declining (BirdLife International 2018j). There were an estimated 1,118,000 breeding pairs in 2019 (ACAP 2022).

APPENDIX C: Habitats that are regarded as critical to the survival of threatened albatross and petrel species breeding within Australia's jurisdiction
Under section 270 of the EPBC Act a recovery plan must, to the extent to which it is practicable to do so, identify the habitats that are regarded as critical to the survival of the threatened species. Albatrosses and petrels in Australia's jurisdiction use two broad categories of habitat: breeding habitat (remote islands) and foraging habitat (southern oceans). This section describes the habitat that is critical to their survival within areas under Australia's jurisdiction.
Breeding habitats
Albatrosses and petrels breed at only six localities under Australia's jurisdiction. These are:
Macquarie Island (including Bishop and Clerk Islets)
Albatross Island
Pedra Branca
The Mewstone
Heard Island and McDonald Islands
Australian Antarctic Territory at Giganteus Island, Hawker Island and the Frazier Islands.
These remote offshore islands constitute the only suitable breeding habitat under Australia's jurisdiction and should be regarded as habitat that is critical to the survival of albatrosses and petrels in Australia. Shy Albatross is endemic to Australia and the breeding habitats for this species (Albatross Island, the Mewstone, and Pedra Branca) comprise its entire breeding habitat. Macquarie Island, Heard Island and McDonald Islands and the AAT host several species of albatrosses and petrels. Many of these populations are very small and are critical for maintaining the genetic diversity necessary to ensure the viability of these species in Australia.
There are no other islands within Australia's jurisdiction that are considered to be potential or former breeding habitat for albatrosses and petrels.
A brief description is provided below about each albatross and petrel breeding location within Australia's jurisdiction including information on their protection status, geography, flora, fauna, and the effects of human occupation.
Macquarie Island (and Bishop and Clerk Islets): 54°37'S, 158°51'E and 55°06'S, 158°41'E, respectively
Species
The following albatross and petrel species covered by this recovery plan breed on Macquarie Island (and Bishop and Clerk Islets):
Wandering Albatross
Black-browed Albatross
Grey-headed Albatross
Light-mantled Albatross
Southern Giant Petrel
Northern Giant Petrel
Grey Petrel.
Protection status
designated a Biosphere Reserve in 1977
designated a Nature Reserve in 1978
Macquarie Island Management Plan implemented in 1991
designated a World Heritage Area in 1997
Geography
Macquarie Island is located in the Southern Ocean, about 1500 km south-east of Hobart, Tasmania, 40 km from the Antarctic Convergence. This sub-Antarctic island is the exposed crest of the Macquarie Ridge. The island is 32 km long by 5 km wide at its broadest point and about 13 000 ha. It rises abruptly from the ocean to form an undulating plateau, usually between 200-300 m above sea level, with a maximum altitude of 433 m. The north-western portion of the island is fringed by a raised beach terrace 15 m above sea level and up to 1 km wide.
Bishop and Clerk Islets lie 37 km to the south of Macquarie Island. These small islets are poorly known because of difficulty of access. They are mostly barren rock less than 50 m high and are geologically similar to the main island (Selkirk et al. 1990).
Flora
There are no trees on Macquarie Island. However, there are 45 species of vascular plants, as well as numerous moss and lichen species. These species are often associated to form one of five vegetation communities: feldmark, grasslands, herbfield, fen and bog. Three plant species are endemic to Macquarie Island: Azorella macquariensis, Corybas dienemus, and Puccinellia macquariensis. Five introduced plant species have become naturalised (Selkirk et al. 1990). The cushion-like Colobanthus muscoides is the only vascular plant on Bishop and Clerk Islets (Parks & Wildlife Service 2006).
Fauna
Macquarie Island is inhabited by a large variety of wildlife. About 86,500 Southern Elephant Seal (Mirounga leonina), fur seals (Arctocephalus spp.), and around 3.5 million seabirds breed on the island (Selkirk et al. 1990). Seventy-two bird species have been recorded on Macquarie Island. Twenty seabird species breed on Macquarie Island, notably King Penguin (Aptenodytes patagonicus), endemic Royal Penguin (Eudyptes schlegeli), Southern Rockhopper Penguin (Eudyptes chrysocome) and Gentoo Penguin (Pygoscelis papua). Over a million birds attend a rookery at Hurd Point at the southern end of the island during the breeding season (Selkirk et al. 1990).
Albatross and petrel breeding locations
Wandering Albatross at Macquarie Island usually nest in a loose colony on moderately wind-exposed areas of the plateau edge up to an altitude of 250 m. The same nest is commonly re-used (Tickell 1985). Nests have been recorded along the western side of the island, extending around to the southern side at Petrel Peak and the northern side at Handspike Corner. Nests have also been recorded on the raised beach terrace areas, from the north-western corner to Aurora Cave. Black-browed Albatross is a colonial species and breeds in small numbers on South-West Point. Three small colonies and several solitary nests are located in this area. A larger population of Black-browed Albatrosses breed on Bishop and Clerk Islets (Brothers & Ledingham 2008). The Grey-headed Albatross forms dispersed colonies with the breeding population confined to the slopes on the southern side of Petrel Peak, West Rock and the slopes opposite West Rock. The majority of birds breed on the steep, tussocky southern slopes of Petrel Peak. The Light-mantled Albatross breeds solitarily or in loose colonies and has the largest breeding distribution of all the albatrosses on Macquarie Island. Nests are found at the northern end of the island around Bauer Bay, North Head and Sandy Bay. Nests are also found in the south around Caroline Cove, Hurd Point and Lusitania Bay. Southern Giant Petrels form loose breeding colonies on the coastal plateau or headlands, or on exposed flats, hillsides or ridge tops (Voisin 1988). Most of the adult birds roost communally on the coastal beaches and around lakes. Northern Giant Petrel establish solitary nests at low altitudes among dense tussock-grass on the coastal flats around the island (Gales & Brothers 1996). The Grey Petrel breed in loose colonies along the escarpment of the east and west coasts of the island, with the highest density of burrows at North Head.
Introduced species
Table 41 indicates that up to 2021, sixteen species of vertebrates are known to have been introduced to Macquarie Island since its discovery. Four of these species are still present on Macquarie Island, with rabbits, rats and mice eradicated from the island recently (Parks & Wildlife Service 2014). Sindel et al. (2017) identified three invasive, non-native plant species as well-established on the island: meadow grass (Poa annua), chickweed (Stellaria media) and starweed (Cerastium frontanum), none of which were identified as having a population-level impact on the albatross and petrel populations.
Table 41: Vertebrate animal species introduced to Macquarie Island.
Introduced species still present on Macquarie Island, 2021
Introduced species no longer present on Macquarie Island, 2021
Macquarie Island has a long history of human impacts. Seal and penguin oil harvesters occupied the island from 1810 to 1920 (Cumpston 1968, Townrow 1988). Albatrosses and giant petrels were harvested for food throughout this time, particularly in the early years (Cumpston 1968). While the number of albatrosses and giant petrels taken by the early settlers is unknown, it is likely to have been excessive, given the extent that other species were exploited. For example, sealers killed over 80,000 Southern Elephant Seals within the first 20 years of occupation, with fur seals completely eliminated from Macquarie Island after 25 years of exploitation (recolonising the island from the 1960s) (Rounsevell & Brothers 1984, Hindell & Burton 1988).
Wekas were introduced to Macquarie Island by the sealers as a source of food. These aggressive birds preyed upon penguin chicks, burrow-nesting petrels and invertebrates. An eradication program for wekas began in 1985 and ended when the last weka on the island was shot in 1988 (Copson 1988). Feral cats and rodents were recorded on the island by the 1820s and 1880s, respectively. Recent pest control programs ensured cats were eradicated by 2002, and rodents by 2014. Rabbits were introduced to the island in the 1870s and significantly modified the distribution of vegetation alliances, particularly the grasslands (Rounsevell & Brothers 1984). Rabbit control commenced in 1978 with the island declared free from rabbits in 2014, with subsequent recovery of plant communities (Parks & Wildlife Service 2014).
Few historical structures remain on the island. The modern station, located on the Isthmus, is comprised of over 40 buildings and structures for scientific and tourism purposes. There are also some field huts located elsewhere on the island (Parks & Wildlife Service 2006).
The Macquarie Island Nature Reserve and World Heritage Area Management Plan 2006 provides guidelines preventing activities likely to impact upon wildlife on the island (Parks & Wildlife Service 2006).
Albatross Island: 40°23'S, 144°39'E
Species
The following albatross species breeds on Albatross Island:
Shy Albatross.
Protection status
designated a Nature Reserve in 1981
Albatross Island Management Plan under development
Geography
Albatross Island is located in western Bass Strait, 70 km northwest of Stanley. The small island is only 1100 m long, by 200 m wide, comprising 33 ha. The rocky island rises steeply from the surrounding sea to a height of about 35 m. A deep 'gulch' runs through the short axis of the island near its northern end (Green 1974).
Flora
Twenty-three plant species, including two small shrub species, have been found on the island.
Fauna
Albatross Island once contained a large population of fur seals before sealers exterminated the population. Fur seals now regularly haul out on Albatross Island. Shy Albatross, Fairy Prion (Pachyptila turtur), Little Penguin (Eudyptula minor), Short-tailed Shearwater (Puffinus tenurostris) and Silver Gull (Larus novaehollandiae) breed on the island. Numerous other birds are occasionally seen on the island. In addition, at least two species of skink (Leiolopisma pretiosum and Leiolopisma metallicum) are found on the island (Green 1974).
Introduced species
The following invasive species have colonised the island: common starling (Sturnus vulgaris), common blackbird (Turdus merula), mirror bush (Coprosma repens) and winter grass (Poa annua).
Shy Albatross breeding locations
Shy Albatross nest on the top of the island. Colonies have formed in four areas: in the north-east, east, south-east and western edges of the island. These remnant colonies were formerly interconnected, except for the northern and southern sectors.
Effects of human occupation
The first European sighting of the Shy Albatross colony on Albatross Island was by George Bass in 1798. Historically, about 11,000 breeding pairs are thought to have nested on the island annually (Alderman et al. 2011). By 1909, however, plume and egg hunters had decimated the colony to only 250-300 nests (Johnstone et al. 1975).
The Mewstone: 43°44'S, 146°22'E
Species
The following albatross species breeds on the Mewstone:

Protection status
incorporated within the Southwest National Park
Southwest National Park designated a Biosphere Reserve in 1978
incorporated within the Tasmanian Wilderness World Heritage Area in 1989.
Geography
The Mewstone is located 123 km south-west of Hobart, Tasmania. The location is 450 m long and only 150 m wide, comprising 13 ha. The Mewstone rises precipitously from the sea to a height of 133 m. A ridge consisting of loose boulders and numerous rock crevices runs in a south-east direction. The only flat tracts on the island occur along the summit of the ridge. The steep sides of the ridge are occasionally interspersed with gently sloping ledges.
Flora
Only seven species of plants occur on the island, Senecio leptocarpus, Senecio lautus, Carpobrotus rossii, Poa poiformis, Asplenium obtusatum, Chenopodium glaucum, and Salicornia quineflora. These small plants grow opportunistically in crevices or cavities where soil has accumulated (Brothers 1979a).
Fauna
Shy Albatross and Fairy Prion nest on the island. Other birds recorded on the island include Common Diving-petrel (Pelecanoides urinatix), Black-faced Cormorant (Phalacrocorax fuscescens) and Silver Gull. The Australian Fur Seal (Arctocephalus pusillus) occurs in moderate numbers, and a skink, Leiolopisma pretiosum, is abundant (Brothers 1979a).
Introduced species
None known.
Shy Albatross breeding locations
Loose nesting colonies occur along the summit and on the rock ledges on both sides of the island. Some nests are located only 15 m above sea level, but most are at higher levels. Two-thirds of the nests are built on the western side of the island (Brothers 1979a).
Effects of human occupation
The Mewstone has never been inhabited. An unknown number of eggs may have been collected early in the 20th century. However, the island's remote location ensures that direct human interference is minimal (Brothers 1979a).
Pedra Branca: 43°52'S, 146°58'E
Species
The following albatross species breeds on Pedra Branca:
Shy Albatross.
Protection status
incorporated within the Southwest National Park
Southwest National Park designated a Biosphere Reserve in 1978
incorporated within the Tasmanian Wilderness World Heritage Area in 1989
Geography
Pedra Branca lies 111 km south-west of Hobart Tasmania. The island is 270 m long, 10 m wide and comprises 2.5 ha. Pedra Branca is essentially a rock mass emerging from the surrounding sea. The east and west slopes rise steeply to meet at a central ridge less than 60 m in height, running in a north-south direction.
Flora
Salicornia blackiana is the only plant species on the island. This species occurs sparsely and is confined to cracks among the rocks (Brothers 1979b).
Fauna
Shy Albatross, Australasian gannet (Morus serrator), Black-faced Cormorant, Fairy Prion and Silver Gull all breed on Pedra Branca. Australian Fur Seal inhabit the island, as does the endemic Pedra Branca Skink (Pseudemoia palfreymani) (Brothers 1979b).
Introduced species
None known.
Shy Albatross breeding locations
The main Shy Albatross colony is located on the south-east section of the island above 25 m where the sheer slope begins to level out making conditions suitable for nesting. Numbers gradually decrease northwards from the main colony (Brothers 1979b).
Effects of human occupation
The island has never been inhabited. It is not known for certain whether humans have exploited Shy Albatross on Pedra Branca in the past. Due to the island's remote location and the extreme difficulty of access, human interference is unlikely (Brothers 1979b).
Heard Island and McDonald Islands: 53°06'S, 73°32'E and 53°02'S, 73°36'E, respectively
Species
The following albatross and petrel species covered by this recovery plan breed on Heard Island and McDonald Islands:
Black-browed Albatross
Light-mantled Albatross
Southern Giant Petrel.
Protection status
Antarctic Marine Living Resources Conservation Act 1981
listed on the Register of National Estate in 1983
Environment Protection and Management Ordinance 1987
Heard Island and McDonald Islands Marine Reserve Management Plan 2014-2024
designated a World Heritage Area in 1997
Geography
The external Territory consists of a remote group of islands lying close together in the Indian Ocean sector of the Southern Ocean.
Heard Island and McDonald Islands are an external Territory located in the Southern Ocean, 4100 km south-west of Perth, Western Australia, and south of the Antarctic Polar Front. Heard Island and McDonald Islands are an external Territory located in the Southern Ocean, 4100 km south-west of Western Australia, and south of the Antarctic Polar Front. Heard Island is 20 km wide, 43 km long and comprises 36,800 ha. It is dominated by Big Ben, an active volcano which rises to 2745 m at Mawson Peak (Australia's highest point outside the AAT). To the north-west is Anzac Peak (715 m), a subsidiary volcanic cone. Glaciers cover approximately 80 percent of the island. The remaining ice-free areas are mostly narrow coastal flats at the north-western and eastern ends of the island and along some northern beaches. The McDonald Islands lie 44 km to the west of Heard Island and, comprise some 360 ha. McDonald Island has doubled in area since 1980 following significant volcanic activity.
Flora
The vegetation of the island group is typically sub-Antarctic comprised predominantly of bryophytes, lichens, mosses, liverworts and tussock grasses. Eleven species of vascular plants are known to occur on Heard Island and five on the McDonald Islands. Six major higher plant communities dominate the islands: tussock grassland, meadow, herbfield, pool complex, cushion carpet and fellfield. The islands are void of woody plants (Commonwealth of Australia 2014).
Fauna
Black-browed Albatross, Light-mantled Albatross and Southern Giant Petrel breed on Heard Island and McDonald Islands (Commonwealth of Australia 2014). Fifteen other avian species breed on the islands. Heard Island Sheathbill (Chionis minor nasicornis) is a strongly defined subspecies endemic to the islands. Four species of burrow-nesting seabirds breed in tens of thousands on Heard Island: Antarctic Prion (Pachyptila desolata), Fulmar Prion (Pachyptila crassirostris), South Georgia Diving-petrel (Pelecanoides georgicus) and Common Diving-petrel (Pelecanoides urinatrix).
Other seabirds breeding in large numbers on Heard Island and McDonald Islands include: Cape Petrel (Daption capense), Wilson's Storm-petrel (Oceanites oceanicus), Subantarctic Skua (Catharacta antarctica lonnbergi) and Kelp Gull (Larus dominicanus). Vast colonies of Macaroni penguins (Eudyptes chrysolophus), over one million breeding pairs, occur on both Heard Island and McDonald Island. There are also large numbers of Southern Rockhopper, Gentoo, and King Penguin. Three seal species breed on the islands: Southern Elephant Seal, Antarctic Fur Seal (Arctocephalus gazella) and Subantarctic Fur Seal (Arctocephalus tropicalis). Some 127 species of terrestrial invertebrates (many of which are endemic) have been found to occur on the islands (Commonwealth of Australia 2014).
Introduced species
The introduced winter grass Poa annua is present on Heard Island, as well as several non-native invertebrate species. It is thought that this grass species was introduced by natural processes, probably by skuas from the Kerguelen Islands where it is widespread, because the grass was initially recorded in 1987 in two recently deglaciated areas where human visitation had not occurred (Commonwealth of Australia 2014).
Albatross and petrel breeding locations
The ice-free areas of Heard Island are mostly confined to the narrow coastal flats at the north, north-western and eastern ends of the island. These are the main breeding areas for Black-browed Albatross, Light-mantled Albatross, and Southern Giant Petrel. There have been occasional sightings of Wandering Albatross on Heard Island at Cape Gazert (Johnstone 1982).
Effects of human occupation
Heard Island was the focus of a major sealing industry from 1855 to 1929. It is likely that the albatross and giant petrel populations were exploited for food throughout this period (Downes 2002). In 1947, jurisdiction over Heard Island and the McDonald Islands was transferred from the United Kingdom to Australia. Australia used Heard Island as a meteorological base until 1954. Australian National Antarctic Research Expeditions occurred in the summers of 1985-1989, with an over-wintering expedition in 1992. Other visits to the island have been of a short duration, and include carefully administered tourism visits. All visits to Heard Island require prior permission from the Department of Climate Change, Energy, the Environment and Water (the administering authority), and visitors are not permitted to disturb seabirds or other animals. The McDonald Islands have been visited twice, in 1971 and 1980. Visits to McDonald Islands are now not permitted, as the location is subject to intermittent volcanic activity (Stephenson et al. 2005, Commonwealth of Australia 2014).
Global warming is having a dramatic impact on the island group including changes in weather patterns and glacial retreat, with vegetation and lagoons now existing where once there were sea-front, glacier snouts (Thost & Allison 2005, Thost & Truffer 2008).

Geography
The AAT covers about 5.9 million km2 (42% of Antarctica). Less than 0.2% of the continent is permanently ice-free. It is the driest, coldest and windiest continent on earth. It is also the highest continent on earth, with an average elevation of 2300 m.
Flora
Over 500 species of algae have been found in continental Antarctica, along with 125 lichen species and 30 mosses (Soper 2004).
Fauna
In the Antarctic region Crabeater Seal (Lobodon carcinophagus) and Southern Elephant Seal breed along the Antarctic coastline and on offshore islands. Antarctic Fur, Weddell (Leptonychotes wedellii), Ross (Ommatophoca rossii) and Leopard (Hydrurga leptonyx) seals also breed in the region. Ten seabird species breed within the Antarctic region: Southern Giant Petrel, Southern Fulmar (Fulmarus glacialoides), South Polar Skua (Catharacta maccormicki), Antarctic Prion (Pachyptila desolata), Adélie Penguin (Pygoscelis adeliae), Emperor Penguin (Aptenodytes forsteri), Antarctic Petrel (Thalassoica antarctica), Cape Petrel, Snow Petrel (Pagodroma nivea) and Wilson’s Storm-petrel (Soper 2004).
Introduced species
None known.
Southern Giant Petrel breeding locations
Each of the Southern Giant Petrel breeding sites are within designated Antarctic Specially Protected Areas (ATCM 2013, 2015, 2016). Southern Giant Petrel breeding sites within the AAT comprise Giganteus Island 16 km west from Mawson station, Mac.Robertson Land (16 ha), Hawker Island 7 km south-west of Davis station, Princess Elizabeth Land (190 ha), and the Frazier Islands 16 km north-west of Casey station, Wilkes Land (60 ha) (ATCM 2013, 2015, 2016). Colonies are established on open gravel areas and rocky outcrops (Woehler et al. 1990, Woehler 1993).
Effects of human occupation
During the austral summer 1820/21, two sealing masters working from the South Shetland Islands (discovered only two years prior) independently landed on the Antarctic Peninsula. By 1892, over 1100 sealing ships had visited Antarctic regions (Headland 1993). Australia's record of involvement with Antarctic exploration dates back to 1886 when the Australian Antarctic Committee was founded. The first research expedition to winter on the Antarctic continent occurred 12 years later. Australia has three permanent scientific research stations within the AAT: Mawson station (near Giganteus Island), Davis station (near Hawker Island) and Casey station (near the Frazier Islands).
The habitat loss and disturbance to nesting sites associated with construction and operations of research stations have directly affected at least two species: Snow Petrel and Wilson's Storm-petrel. There are also data suggesting regular visits to colonies of Adélie Penguin and Southern Giant Petrel may disturb breeding birds, causing colonies to decrease (Woehler 1993), although this interpretation for some of these data for Southern Giant Petrel is contested (Wienecke et al. 2009).
Human access to each of the Southern Giant Petrel breeding sites is strictly prescribed during the austral summer breeding season under the respective management plans for each of the Antarctic Specially Protected Areas (ATCM 2013, 2015, 2016).
