UPDATE:  The Short-tailed Albatross have an egg for the 2023/24 season and incubation is proceeding, with the male having taken over duties from the female after she laid her egg last month. On 2 November George and Geraldine's first chick (2018/19 season) was sighted back on Sand Midway's island as a four-year old juvenile.  It has been seen ashore previously (along with a younger sibling).  Perhaps there will be more than a single breeding pair on Midway Atoll one day?

The Vulnerable Short-tailed Albatross Phoebastria albatrus pair, known as George and Geraldine, are back on Midway Atoll. The birds were sighted together on Sand Island by a Fish and Wildlife Service volunteer team on 16 October.

“George was banded as a chick on the island of Torishima off the coast of Japan in 2005. He first arrives to Kuaihelani [Midway Atoll] in November 2006. For many years he would return as truly a lonesome George until Geraldine appears in 2016 when they are seen courting and practicing their dance moves. However, it wasn't until 2019 when they reared their first chick on Midway Atoll National Wildlife Refuge.”

The sole Short-tailed Albatross pair on the atoll has now raised four chicks to fledging; two of have been seen back on Midway as juveniles. Access previous posts to ACAP Latest News on George and Geraldine here.

Maëlle Connan (Marine Apex Predator Research Unit, Nelson Mandela University, Gqeberha, South Africa) and colleagues have published early view and open access in the journal Biological Invasions on observations of introduced House Mice Mus musculus attacking and killing adult Critically Endangered Tristan Albatrosses Diomedea dabbenena on Gough Island and adult Vulnerable Wandering Albatrosses D. exulans on Marion Island.  The death of breeding adults confirms the need to eradicate the mice. Unfortunately, the attempt by the Gough Island Restoration Programme to eradicate Gough’s mice in 2021 failed. Eradication of the mice on Marion Island is set to take place in winter 2026, according to the Mouse-Free Marion Project.

The publication also reports observations of two wounded Wandering Albatrosses (thought to also be due to mice) photographed at the same time; their fate being unknown. See the photographs below.

The paper’s abstract follows:

“Invasive rodents threaten native species in numerous ecosystems, especially oceanic islands. The House Mouse Mus musculus is the only introduced mammal species on sub-Antarctic Gough and Marion Islands. Ample evidence exists of mice preying upon seabird chicks on these two islands, but there have been only a few reports of attacks on adult seabirds, none of which has been fatal. We report the first deaths of adult great albatrosses due to mouse attacks. On Gough Island, three Tristan Albatrosses Diomedea dabbenena (Critically Endangered) brooding small chicks were observed with wounds typical of mouse attacks in March-April 2021; two likely abandoned their chick, causing breeding failure, and the third was found dead eight days after discovery with large blowfly larvae in the wound. On Marion Island, two wounded and eight dead adult Wandering Albatrosses D. exulans (Vulnerable) were found in April 2023. Inspection of the wounded individuals, as well as the injuries on the fresh carcasses strongly suggest that mouse predation was the cause of death. Gough Island is home to virtually all Tristan Albatrosses, and Marion Island is the single most important breeding site for Wandering Albatrosses, home to about a quarter of all breeding birds. The death of breeding adults of these long-lived species emphasizes the urgent need to eradicate introduced mice from these islands.”

Celebrating 100 years of conservation: Forest & Bird seeking to crown New Zealand’s Bird of the Century

6 Solander May 2013 0446Which bird will get your vote? The ACAP-listed Buller's Albatross is one of 77 birds to choose from in Forest & Bird's search for New Zealand's Bird of the Century. A pair of non-breeding Buller’s Albatrosses preen on Solander Island; photograph by Jean-Claude Stahl

The New Zealand conservation organisation, Forest & Bird, are marking their 100th birthday this year and as part of their celebrations are searching for a mighty feather to put in their cap.  

In a twist on the organisation’s annual Bird of the Year competition, Forest & Bird are asking the bird-loving public to cast their vote to crown New Zealand's Bird of the Century.

Seventy-seven native birds are in the running for the accolade, including two ACAP-listed species: the globally Endangered and Nationally Critical Antipodean Albatross Diomedea antipodensis and the globally Near Threatened and nationally Declining Buller's Albatross Thalassarche bulleri.

To raise awareness of ACAP-listed species and the threats they are facing, the Agreement has been producing a series of infographic posters which can be downloaded at the ACAP website. The Antipodean Albatross infographic, sponsored by New Zealand’s Department of Conservation (NZDOC), is amongst those already featured, with the Buller’s Albatross infographic (also sponsored by NZDOC) intended to be be available in the first half of 2024.

Five extinct species have also been included as candidates in the competiton in order to highlight the loss of biodiversity in New Zealand, and to serve as a reminder to protect those species that remain.

Forest & Bird have created a profile for each of the 77 bird contestants on their website, here. Profiles include information on the species, their conservation status, and in some cases a recording of their song. Voters are permitted to select up to five birds for submission to the competition.

Voting opened on Monday 30 October and will close at 5pm on Sunday 12 November 2023. The winning bird will be announced on Monday 13 November 2023.

Marion Island joins the Island-Ocean Connection Challenge to help save its albatrosses and petrels at risk from introduced House Mice

BirdLife South Africa has joined the Island-Ocean Connection Challenge (IOCC), a global initiative aiming to restore, rewild and protect islands, oceans and communities (click here). This aims to support its work in partnership with the South African Department of Forestry, Fisheries and the Environment via the Mouse-Free Marion (MFM) Project to save internationally significant albatross populations, such as of the Vulnerable Wandering Albatrosses Diomedea exulans, that are at risk from introduced House Mice Mus musculus on Marion Island. At a little over 30 000 hectares, the removal of mice from Marion Island will be the largest rodent eradication project in the world to be undertaken in a single operation.

The IOCC aims to restore and rewild 40 globally significant islands worldwide by 2030, from sub-Antarctic islands like Marion Island to tropical islands bursting with colourful marine life and coral. Restoring islands by removing invasive species has been repeatedly proven to be one of the most impactful ways to restore biodiversity and island ecosystems. There have been more than 1000 successful island invasive species eradications worldwide that have resulted in long-term benefits, including increased populations of seabirds, land birds and native plants, recovery of natural ecosystem functions, protected and thriving reefs and a more climate-resilient island.

Mark D. Anderson, CEO, BirdLife South Africa and Chair of the MFM Project Management Committee, explains: “Islands are biodiversity hotspots and therefore provide a crucial focus for global conservation efforts. We have joined the IOCC to add impetus to international actions restoring islands by tackling the important environmental issue of invasive alien species. Marion Island is home to two million seabirds, including four species of albatrosses and a range of other species including petrels and penguins, several of which are threatened with extinction. It is vital that we remove the invasive mice, as otherwise Wandering Albatrosses – arguably the most iconic of the ocean-wandering seabirds – and the majority of Marion Island’s globally important seabirds, could become locally extinct.”

“Rodent-free islands offer a glimmer of hope in the fight against climate change and biodiversity loss. Successful eradications have shown that islands can recover to their former ecological condition in a relatively short time. Joining the IOCC will help raise awareness of the current risk posed to Marion Island, and the urgency needed to prevent the worst-case scenario from happening. We are delighted to have joined this important worldwide initiative and, by being part of it, look to make a step-change in protecting Marion Island’s biodiversity forever.”

Dr Anton Wolfaardt, MFM Project Manager, adds: “Put simply, if we can remove invasive mice from Marion Island we can address once and for all one of the significant threats that the island’s seabirds face, and thus facilitate a favourable conservation future for this globally important island and its magnificent seabirds. Rather than containing or mitigating the threat, we solve it. Although the seabird populations on Marion Island are being increasingly impacted by mice, we have an opportunity to intervene to remove that threat and allow the seabird populations to recover naturally without the need for species reintroduction programmes.”

“The global importance of the seabird populations on Marion Island cannot be overstated, so we must do everything in our power to protect them. Becoming part of the IOCC will help us achieve this goal and contribute to global biodiversity objectives.”

Dr Penny Becker, Vice President Conservation at Island Conservation and a co-founder of the IOCC, writes: “Restoring and rewilding islands is not just an act of conservation; it is one of our most powerful defences building resiliency against climate change. By nurturing these ecosystems, we build stronger environments and help biodiversity hotspots like Marion Island to recover”.
