The Gibson’s subspecies population of the Antipodean Albatross on Adams Island is half its former size

The final report for the Conservation Services Programme project, POP2025-04 Auckland Islands seabird research: Gibson’s albatross, by Johannes Chambon (Department of Conservation, Dunedin, New Zealand) and colleagues, is now available.  It shows the population of the subspecies gibsoni of the Endangered Antipodean Albatross has halved on Adams Island, Auckland Islands since 2005.

The report’s summary follows:

“Gibson’s albatross (Diomedea antipodensis gibsoni) has been in decline since 2005. Research into the causes of and solutions to the falling numbers of Gibson’s wandering albatross includes an annual visit to the main breeding grounds on Adams Island, and this report describes the results of the field programme in the 2025/2026 breeding season. Breeding success in 2025 was 60%, with 83 chicks produced in the study area, all of which were banded before fledging. Mean adult female survival in 2014-2024 at 93% remains slightly lower than the mean 95% before the 2005 population crash. To increase the proportion of the total breeding population ground-counted annually, a new census block was demarcated and counted in 2026: Turbott Square, within the high-density Fly Basin colony.  This brings the proportion of the total Adams Island breeding population ground-counted annually to 12.4% rather than 10% counted formerly. A total of 5,032 pairs were estimated to be breeding on Adams Island in 2026, comparable to 2025 (4,865 pairs). The total number of Gibson’s albatross breeding pairs remains half the size of the pre-crash nesting population.”

THE ACAP MONTHLY MISSIVE. Weeding invasive plants in the Pacific is in support of World Albatross Day’s theme of “Habitat Restoration” for 2026

In May 2000 I spent a week with other attendees on the USA’s Midway Atoll after the Second Albatross and Petrel Conference, held in Honolulu on the Hawaiian island of Oahu.  An abiding memory is of the huge numbers of Laysan Albatrosses Phoebastria immutabilis, seemingly everywhere over the atoll, including a courting pair (presumably pre-breeders) right below my ground-floor bedroom window (left open for the heat), that shouted at each other all night long.  Another memory was of the late-season thickets of the invasive Golden Crownbeard Verbesina encelioides, among which the Black-footed P. nigripes and Laysan Albatrosses bred on both the atoll’s Eastern and Sand Islands.  Native to the American mainland it is an alien on the Northwestern Hawaiian islands where it occurs, including Midway (where thought introduced in the 1930s) and Kure Atolls (click here).  Adult albatrosses can get their wings caught in its branches and the dense vegetation blocks cooling sea breezes, creating oven-like conditions for their chicks, putting them at risk of death from dehydration.  Eradication efforts began in the late 1990s (click here), but in 2000 when I visited there were still extensive stands of the plant on Sand Island.

Since my visit, use of hand-sprayed herbicides in the mid-2010s and the removal of plants has greatly changed the appearance of the albatross breeding flats, as these two photographs taken on Midway’s Eastern Island 12 years apart testify.

However, despite earlier claims of eradication being imminent, the abiding seedbank on both Midway islands has required the ongoing removal of emerging seedlings and hidden plants, as reported last September by the Friends of Midway Atoll National Wildlife Reserve (FOMA).

“For over 20 years, with several million dollars invested by the U.S. Fish and Wildlife Service (USFWS) and the National Fish and Wildlife Foundation (NFWF), with FOMA's additional support, the effort to eradicate invasive Verbesina encelioides and other incipient weeds from Midway Atoll has steadily advanced—and today, we’re closer than ever.  This highly invasive, non-native plant once threatened vital seabird nesting habitat. But thanks to dedicated staff and volunteers, the number of plants found each year continues to decline.  A key breakthrough?  Targeting the persistent seedbank hidden in Midway’s sandy soils—an approach that’s proving eradication is possible.”

Watch a short video of FOMA volunteers pulling out small Verbesina plants among Laysan Albatrosses on Midway’s Sand Island, and another video hunting for and removing seedlings from among natural vegetation.

Eradicating alien plants on islands that support breeding populations of ACAP-listed albatrosses and petrels fits well within this year’s theme of “Habitat Restoration” for World Albatross Day on 19 June.  ACAP Latest News will be pleased to hear of other attempts to eradicate invasive plants at localities where ACAP-listed albatrosses and petrels breed.

Helping the Shy Albatross face climate change via habitat restoration

Here follows a report of efforts to improve the breeding success of Near Threatened Shy Albatrosses Thalassarche cauta that falls directly within the theme of “Habitat Restoration” for World Albatross Day on 19 June 2026.

“The Shy albatross (Thalassarche cauta) is listed as Vulnerable under the Threatened Species Protection Act 1995.  It is unique to Tasmania, breeding exclusively on three offshore islands: Albatross Island in western Bass Strait and Pedra Branca and the Mewstone south of Tasmania. The total population is estimated to be around 15 000 annual breeding pairs.

Shy albatross populations have been studied since the 1980s by the Department of Natural Resources and Environment Tasmania (Marine Conservation Program) and in partnership with the CSIRO has been working to understanding how shy albatross will be impacted by climate change in the short and long-term. We aim to use this knowledge to identify practical on-ground adaptation options that will help buffer the species against negative effects.

Potential adaptation options include building wind breaks, tr uanslocations, building artificial nests, reducing disease and reducing bycatch from fisheries. Each option will vary in its magnitude of benefit and act upon different components of the population demographics (through one or more of chick, juvenile or adult survival, and breeding success).

Albatross make nests using mud surrounding the nest area, in which they lay one egg. Higher nests have higher chick survival than low nests.  One of the options we tested to help shy albatross was to supply them with artificial nests made of air-blown concrete. These nests keep the egg and chick out of the mud. In our trial of using more than 100 artificial nests, chick survival was almost three times higher compared to natural nests.

Testing these adaptation options is helping both birds and conservation managers to prepare and cope with a warmer world and provides options to keep larger populations of these magnificent birds.”

The AI-generated “HAIku” comes from the closing remarks of the AC15 Chair, Dr Michael Double

Following Thursday’s outing to Walvis Bay last week, the fifth day of the 15th Meeting of the ACAP Advisory Committee (AC15) in Swakopmund, Namibia was allocated to adopting the final report.  The Secretariat had spent Thursday completing a draft for comment by the attending delegates and observers and by Friday morning a clean version was available for adoption.  In the event, the whole day was not required, and with the report adopted section by section under the Chair of Dr Michael Double, AC15 was wrapped up by the afternoon tea break.  Once Parties have signed off the final report, it will be posted to this website.

During the week, Chief Officers who chair the Advisory Committee and convene the working groups were all re-elected.  Dr, Johannes Fischer (Department of Conservation, New Zealand) joined the existing officers as a Vice-Convenor of the Population and Conservation Status Working Group (PaCSWG), following being nominated by the United Kingdom and seconded by Brazil.

Where the next meeting of the Advisory Committee should be held is always an important matter to decide before the end of the meeting.  Chile offered to host AC16 in August or September 2027, in Punta Arenas in Southern Patagonia.  The Advisory Committee thanked Chile and warmly welcomed the offer.  Advisor to Chile’s Delegation, Mr Luis Adasme (Instituto de fomento pesquero, IFOP), then showed a one-minute video entitled “Punta Arenas & Nature” to whet the attendees’ appetites.  A draft agenda for AC16 was reviewed by the Advisory Committee and will be forwarded to AC members for their consideration in advance of the meeting.

Following the formal adoption of the AC15 report, Michael Double closed the meeting with a vote of thanks to the Namibian hosts, also offering his thanks to his Vice Chair, Tatiana Neves (Brazil), all the Chief Officers, and the Secretariat.
