Localities without records with a present occurrence status in the dataset listed in grey text.

Rachel I. Leihy (Securing Antarctica’s Environmental Future, School of Biological Sciences, Monash University, Victoria, Australia) and colleagues have published open access in the journal scientific data on introduced and invasive species of Antarctica and the Southern Ocean Islands.

The paper’s abstract follows:

“Open data on biological invasions are particularly critical in regions that are co-governed and/or where multiple independent parties have responsibility for preventing and controlling invasive alien species. The Antarctic is one such region where, in spite of multiple examples of invasion policy and management success, open, centralised data are not yet available. This dataset provides current and comprehensive information available on the identity, localities, establishment, eradication status, dates of introduction, habitat, and evidence of impact of known introduced and invasive alien species for the terrestrial and freshwater Antarctic and Southern Ocean region. It includes 3066 records for 1204 taxa and 36 individual localities. The evidence indicates that close to half of these species are not having an invasive impact, and that ~ 13% of records are of species considered locally invasive. The data are provided using current biodiversity and invasive alien species data and terminology standards. They provide a baseline for updating and maintaining the foundational knowledge needed to halt the rapidly growing risk of biological invasion in the region.”

The New Zealand Department of Conservation (DOC) team of rangers based on Rēkohu/Wharekauri/Chatham Islands has reported of a globally Near Threatened and nationally Endemic and Declining Buller’s Albatross Thalassarche bulleri fledgling landing on the main Chatham Island during the night of 18 June and then being rescued and released the next day on World Albatross Day . The team’s report on its Facebook page follows:

“Last Monday was World Albatross Day and, as if on cue, they began to fall from the sky with our office getting three reports in as many days of juvenile Buller’s mollymawks/hōpo/toroa crash landed on roads or farms where they are vulnerable to vehicles and dogs. In May/June each year these fledgling birds are taking their first flight from Rakitchu/Rangitatahi/The Sisters and Motchu Hara/Motuhara/Forty-Fours. Luckily for these birds some very thoughtful and caring members of the community were on hand and got in touch with our team. With the help of rangers and even assistance from our awesome local fire brigade they were relocated to high, windy spots to have a chance at relaunching. Hopefully they’ll be back in about 12 years’ time to have chicks of their own.”

ACAP Latest News reached out to Gemma Green, DOC Ranger (biodiversity) on the Chatham Islands for some more details. In reply, she tells ALN that so far this breeding season five fledgling Buller’s Albatrosses have become grounded on Chatham Island, rescued, and then released on high ground or from sea cliff edges where they will more easily be able to take flight. She writes that they hear of one or two fledgling Buller’s Albatrosses each year although they might not all get found or reported to us. “This year seemed to be particularly bad, maybe due to the unseasonably light easterlies we had over the past couple of weeks. It’s gone back to more normal strong winds now so hopefully no more.”

DOC marine ornithologist, Graeme Taylor says that there have been reports in the past of one or two Northern Buller’s Albatrosses T. bulleri platei showing up grounded on beaches around the northern end of the main Chatham Island and mostly in June which is the month they fledge. These have been assumed to have come off The Sisters where the northern subspecies breeds as the winds are typically northerly or westerly at the Chatham Islands and this direction would blow birds from The Sisters up on the northern beaches. But with the easterly winds this season’s grounded birds are just as likely to have come from the Forty-Fours which are well out to the east of the main island.

With The Sisters being c. 16 km away from the main Chatham Island the situation appears similar to that of occasional fledglings of the Endangered Indian Yellow-nosed Albatross T. carteri from South Africa’s Prince Edward Island being recorded ashore on Marion Island – where the species does not breed – at a distance of 22 km (click here). The Forty-Fours are about three times as distant at 50 km, so it may be the crash-landed albatrosses more usually came from The Sisters under the influence of the prevailing westerly winds.

Graeme Taylor adds that back in April 2007 a presumed Campbell Albatross T. impavida (Vulnerable) was found on the road near the Chatham Island’s DOC office. It was a recently fledged juvenile but separating them at that age from Black-browed Albatrosses T. melanophris (Least Concern) is problematic because both then have dark eyes.

The Pacific Seabird Group (PSG) has announced “Faces of Seabird Conservation” as the theme for its 51^stAnnual Meeting being held in Seattle, Washington, United States, 21-23 February 2024. 

The theme has been chosen by PSG to shine, “a spotlight on the humans that love seabirds”. PSG have put a call-out for the public to get involved and draw attention to a seabird scientist they feel has flown under the radar, announcing on their Instagram page:

“Do you have a favorite established or aspiring seabird scientist you'd like everyone to know more about? How about a dedicated volunteer, logistics coordinator, or local community member who goes the extra mile for seabirds but has never attended a PSG meeting? Or maybe you're teaching (or raising) a seabird enthusiast? Grab a camera, ask them a few questions, and send us a Faces of Seabird Conservation profile telling us who they are!”

Submissions for Symposia, Special Paper Sessions, and Workshops are also being accepted as are nominations for two awards to be conferred at the meeting.

All information about the meeting can be found at the Pacific Seabird Group’s meeting page on the website, here.

At ACAP’s most recent meetings, held in Edinburgh, Scotland, UK in May, its Population and Conservation Status Working Group (PaCSWG) considered an information paper (PaCSWG 7 Inf 05) submitted by the Mouse-Free Marion (MFM) Project and co-written by Dr Azwianewi Makhado (South African Department of Forestry, Fisheries and the Environment, DFFE) and Dr Anton Wolfaardt (MFM Project Manager). Their paper sets out the background and need for the project that aims to eradicate House Mice on Marion Island and reports on its current status. It ends by inviting the PaCSWG, ACAP and ACAP Parties “to follow our progress, and endorse and support the MFM Project which aims to achieve a more favourable conservation status for Marion Island and its globally important seabirds, including eight ACAP-listed species”. Following discussion, the PaCSWG7 recognised that this is a key project at a major global breeding site and urged all who could support the work to do so. The PaCSWG then recommended that the ACAP Advisory Committee endorse and support the MFM Project.

The 13th Meeting of the ACAP Advisory Committee (AC13) the following week heard a presentation of the PaCSWG report (AC13 Doc 09) from its Convenors that inter alia drew attention to its recommendation on the MFM Project. Following discussion among the ten Parties present, AC13 agreed to endorse and encourage support for the MFM Project, reiterating its importance (click here).

The international support received from ACAP means that all six nations that hold breeding populations of one or more of the eight ACAP-listed species of albatrosses and petrels that breed on Marion Island have endorsed the MFM Project. These are Argentina, Australia, France, Chile, New Zealand and the United Kingdom. Endorsement by these Parties joins government support for the project within South Africa, recently confirmed by Ms Barbara Creecy, Minister of the Department of Forestry, Fisheries and the Environment in her budget speech (click here).

Dr Azwianewi Makhado (DFFE and South Africa’s National Contact Point for the Agreement) writes: “South Africa appreciates the support and endorsement of the progress coming from ACAP’s Advisory Committee at its Thirteenth Meeting held in May. It also appreciates the effort being made by the MFM Project to eradicate mice on Marion Island. The country will continue to provide support for this important project to help conserve the albatross and petrel species that breed on the island.”

Dr Sue Tonin, MFM’s recently appointed Assistant Project Manager, also expresses her thanks: “ACAP’s welcome support of the eradication of House Mice from Marion Island reflects an international understanding of the effectiveness of this approach for protecting vulnerable procellariforms breeding on the world’s islands. The Mouse-Free Marion Project Team is reliant on the pioneering nations, organizations and individuals who are continually refining the techniques we will be using in this operation, and on the dedicated support of researchers and policymakers.”

The international and national endorsements received by the MFM Project are an encouragement to the project’s team and its many supporters and funders in South Africa and around the world to intensify their efforts to ensure the end of Marion’s mice. On a personal note I have visited Marion Island no less than 31 times over a 40-year career as a marine ornithologist, the last time in 2014. I continue to feel a passion for the island and am pleased I can contribute to its conservation as the MFM Project’s voluntary News Correspondent.

With thanks to Robert Crawford, who represented South Africa at the ACAP meetings in Scotland.
