Jorge Avaria-Llautureo (School of Biological Sciences, University of Reading, UK) and colleagues have published open access in the journal Nature Climate Change on more than 20 species of procellariiforms across millions of years of Earth’s climatic history.  Their research combined evolutionary family trees, ancient climate records and ocean temperature data to reveal how these seabirds responded to past periods of warming and cooling.  Rather than shrinking in size as some marine species do, seabirds responded to rapid warming by contracting their ranges and extending their journeys.

The paper’s abstract follows:

Many marine ectotherms have responded to local warming through body-size reductions and dispersal to optimal environments. However, whether endothermic marine species, such as seabirds, exhibit similar responses remains unclear owing to gaps in literature that hinder comprehensive global assessments.  Here we show that globally distributed seabirds (albatrosses, petrels, shearwaters and storm petrels) facing rapid historical climate change responded with changes in geographic range size rather than body mass.  In addition, under higher rates of climate change, species’ ranges contracted most, forcing these species to disperse longer distances.  These historical inferences align with expected responses to modern climate change, as over 70% of extant species contract their ranges and disperse farther under a climate scenario leading to severe warming by 2100.  These results underscore the urgent need to integrate range dynamics into conservation strategies and reveal that the rate of climate change poses the greatest threat to seabird diversity.”

Two weeks of meetings of the Albatross and Petrel Agreement commence today in Swakopmund, Namibia.  Day One kicks off with the Ninth Meeting of the Population and Conservation Status Working Group (PaCSWG9) under the Convenorship of Mark Favero (Argentina), Patricia Serafini (Brazil) and Richard Phillips (UK).  The list of the current 33 PaCSWG members and their affiliations can be viewed here.

The one-day meeting will consider eight Documents and 19 Information Papers.  Note some of these documents are only publicly available as summaries.  According to the meeting’s Draft Agenda, subjects to be discussed include Updates on Species Assessments, Population Status and Trends, and Threats (including management of land-based threats, pollution, climate change and High Pathogenicity Avian Influenza).  The meeting will conclude with a review of the working group’s work programme for the period 2026-2028.

The PaCSWG will produce a written report of its deliberations which will tabled for discussion and adoption by the Fifteenth Meeting of ACAP’s Advisory Committee (AC15) during Week Two of the Swakopmund events, to be held from Monday 1 to Friday 5 June in the Swakopmund Plaza Hotel.

The meeting of PaCSWG9 will be followed by a joint SBWG13/PaCSWG9 meeting held on Tuesday 26 May to discuss cross-cutting issues and a three-day meeting of the Seabird Bycatch Working Group (SBWG13, 27-29 May).

More information on the Namibian meetings is available in three AC15 Meeting Circulars. Terms of Reference for the Population and Conservation Status Working Group can be read from here.

It’s International Day of Biodiversity today

 IDB2026 Logo C

Today is the International Day of Biodiversity (IDB).  Proclaimed by the United Nations to raise awareness of the value of life on Earth, the day serves as a global reminder of the need to safeguard biodiversity and protect the ecosystems that support human well-being.  The day is coordinated by the Convention on Biological Diversity (CBD), the international legal instrument for the conservation and sustainable use of biological resources.

WAD2026 fr horizontal 

The 2026 edition of the IDB has the theme “Acting locally for global impact, Des actions locales à l’impact mondial, Acción local para un impacto mundial”. This fits well with Albatross and Petrel Agreement’s theme for World Albatross Day on 19 June 2026 of “Habitat Restoration”, exemplified by civil society, non-profit organizations and national, regional and local government bodies combining their resources to eradicate alien predators on islands, such as the current projects directed at New Zealand’s Auckland Island and South Africa’s Marion Island.  A second example related to the WAD2026 theme is of NGOs and non profits working with government authorities to create new breeding colonies of albatrosses and petrels, often protected by predator-proof fences, on inhabited Hawaiian Islands and on Mexico’s Guadalupe Island.

These, and other activities related to the conservation of albatrosses and petrels, will be featured at the 15th Meeting of ACAP’s Advisory Committee and meetings of its Population & Conservation Status and Seabird Bycatch Working Groups in Swakopmund, Namibia over the next two weeks.

Imogen Foote (School of Biological Sciences, Victoria University of Wellington, New Zealand) and colleagues have published in the New Zealand Journal of Zoology on identifying seabird bycatch with genetic markers.

The paper’s abstract follows:

Fisheries bycatch mortality is a significant threat facing seabirds worldwide.  Yet, understanding which species are most impacted is hindered by uncertainties when identifying bycatch specimens.  Birds can be damaged by fishing gear and closely related seabird taxa can have overlapping traits, presenting challenges for identification based on morphology and plumage.  Here, we have developed a genetic method for identifying seabirds at risk from bycatch in Aotearoa New Zealand across 36 species including albatrosses, storm petrels, petrels, shags, and penguins.  Cytochrome Oxidase I (COI) analysis enabled identification of all taxa to the genus level, and 75% to the species level.  All but one species (Salvin's albatross, Thalassarche salvini) that could not be successfully identified using COI could be distinguished from their more highly variable mitochondrial control region sequences.  Subspecies of Cape petrel (Daption capense capense/D. c. australe), Antipodean albatross (Diomedea antipodensis antipodensis/D. a. gibsoni), and Buller's albatross (T. bulleri bulleri/T. b. platei) could not be distinguished using either of these loci so will require development of more highly discriminating markers.  Our methodology will be a valuable complement to the current formal identification process of seabird bycatch in South Pacific fisheries, helping to inform future fisheries management and seabird conservation.”

The seventh art collaboration with ABUN in support of World Albatross Day ends with a collage poster

ABUN 52 POSTER WAD2026Collage poster design for ABUN Project #52 “Habitat Restoration” by ABUN Co-founder Kitty Harvill

The international collective Artists and Biologists for Nature (ABUN) has contributed to the conservation of ACAP-listed species every year since 2020 by running an annual project for which contributing artists produce artworks to mark World Albatross Day on 19 June.  Over the seven years no less than 760 artworks illustrating all 31 ACAP-listed albatrosses and petrels have been created, using photographs made available by ACAP supporters to act as inspiration.

For this year’s project, ABUN’s 52nd, artists were requested to produce works featuring the Endangered Atlantic Yellow-nosed Albatross Thalassarche chlororhynchos, endemic to the Tristan da Cunha islands, part of the United Kingdom Overseas Territory of St Helena, Ascension and Tristan da Cunha in the South Atlantic, and the Vulnerable Chatham Albatross Thalassarche eremita, endemic to The Pyramid, Chatham Islands, New Zealand.

ABUN's Project #52, which commenced on 16 February and ran to 03 May, has been in support of the World Albatross Day theme for 2026 of “Habitat Restoration”.  It has resulted in 64 artworks by 37 artists, including several who produced more than one work.  They will be used by ACAP to support “WAD2026” until the actual day on 19 June – and thereafter.

The WAD2026 theme of Habitat Restoration includes such management activities as eradication or control of introduced plants and animals at breeding sites, provision and maintenance of predator-proof fences, establishment of new breeding colonies by attraction techniques such as use of decoys and sound systems and translocations of eggs and chicks, candling and substituting infertile with fertile eggs, placement of artificial nests, supplementary feeding and hydration of chicks and adults, artificial incubation during hatching, and the use of artificial nests, wind breaks, fly repellents and sprinkler systems to improve breeding success.  You can search for projects among over 850 that utilize such management activities on the Seabird Restoration Data Base.
