Albatross and petrel studies have continued for another year at Bird Island, South Georgia (Islas Georgias del Sur)*, adding to long-term datasets held by the British Antarctic Survey.  Previous ACAP Latest News postings on Wisdom the female Laysan Albatross Phoebastria immutabilis of Midway Atoll, who reached the ripe old age of at least 69 this year, prompted the obvious question “which are the oldest birds on Bird Island?”.  A check of demography and ringing recovery databases generated the following information on the oldest birds ringed on the island as chicks.

The initial ringing effort of Lance Tickell and colleagues in the late 1950s and early 1960s is clearly in evidence.  Although there are currently sixty-year old birds on the island, only time will tell whether these longevity records are broken.

The first team members of the Gough Island Restoration Programme (GIRP) have left for the island.  The main aim of the programme being led by the UK’s Royal Society for the Protection of Birds (RSPB is the eradication of the island’s introduced House Mice Mus musculus by an aerial poison bait in a few months’ time.  The mice have taken to attacking seabird chicks and are deemed to be pushing some of them, notably the Critically Endangered and near-endemic Tristan Albatross Diomedea dabbenena, to extinction.  The start of the GIRP has come after more than a decade of on-island research and several years of planning to put together the eradication effort.

Poster Owen Davey FINAL

The advance party sailed on the New Zealand-registered expedition yacht Evohe from Cape Town harbour on Tuesday last week.  ACAP Latest News met with some of the team a few days before to wish them well and to ask them to courier a couple of items to the South African meteorological station on the island on behalf of the Agreement.  With the support of the Antarctic Legacy of South Africa an A3 laminated version of Owen Davey’s World Albatross Day poster has been printed and is now on its way to Gough, there to be displayed in the small laboratory in Gough House, the main accommodation block at the station.  Michelle Risi, one of three field biologists currently monitoring the Tristan Albatrosses (and other seabirds) on the island, is the person who first suggested to ACAP that it consider inaugurating a World Albatross Day, and she also made the contact that resulted in Owen Davey producing his poster free of charge.  Appropriate, then, that she will be able to continue her lab work next to the ‘WAD2020’ poster she instigated.

The United Kingdom’s Royal Society for the Protection of Birds (RSPB) hosts the BirdLife International Marine Programme, with a particular emphasis on stopping albatross declines through implementing practical solutions to reduce bycatch in longline and trawl fisheries and protecting the most important sites for seabirds globally.

The RSPB is looking for a visionary and inspiring marine specialist to head up the Birdlife International Marine Programme, leading the RSPB Global Seas programme, overseeing the Marine Programme Regional Co-ordinators in BirdLife International Partners across the world and co-ordinating the marine policy and scientific work at the BirdLife International Secretariat.

The overall aims of the Marine Programme are to improve the conservation status of the world's seabirds through the adoption of bycatch mitigation measures in longline and trawl fisheries, to identify bycatch mitigation measures in gillnet fisheries; and to delineate and protect marine Important Bird and Biodiversity Areas

The successful candidate will have extensive experience of seabirds and marine issues and excellent skills in facilitation and the development and co-ordination of a dispersed team.

They will be willing to travel worldwide to make the case for improved conditions for birds at sea, through working with partners and persuading operators and policy makers to adopt new methods and also pushing for a high level of uptake of the measures.

Closing date: 16 March 2020.  Find more information here.

Predation risk or foraging opportunity? Wedge-tailed Shearwaters avoid their colonies during full moon

Wedge tailed Shearwater Pacific Islands Avian Health  Disease Program

Andreas Ravache (Aix-Marseille Université, Nouméa, New Caledonia, France) and colleagues have published in the Journal of Experimental Marine Biology and Ecology on why Wedge-tailed Shearwaters Ardenna pacifica decrease their activity at breeding  colonies around the time of the full moon.  The authors postulate decreased activity may be due to higher foraging efficiency of seabirds around during that period, rather than predator avoidance.

The paper’s abstract follows:

“Lunar phase and illumination are known to affect nocturnal behavior of many organisms, particularly through predator-prey interactions.  Visual predators can benefit from higher light levels to increase their activity, while prey may decrease their activity to avoid predation. The lower number of nocturnal seabirds observed on colonies during full moon nights has been mostly interpreted as a predation avoidance strategy.  However, it is also possible that shearwaters take advantage of the moon's illumination to feed also at night, and stay at sea to forage during full moon nights.  We used miniaturized GPS-loggers to obtain 179 tracks from 99 wedge-tailed shearwaters breeding in New Caledonia, to investigate moonlight effects on individual behavior.  Lunar phase significantly predicted self-provisioning trip duration, with individuals performing longer trips around the full moon.  However, this relationship was not significant during chick-provisioning trips when adults have to frequently return to the colony.  Adults mostly returned to the colony during moonlit periods, refuting the predation avoidance theory.  Tracked individuals showed an unexpectedly high amount of nocturnal foraging activity (28% of total activity), positively influenced by the presence of the moon. δ15N stable isotope values were significantly related to the percentage of nocturnal foraging, but with a weak relationship, impeding our ability to confirm that wedge-tailed shearwaters fed on different prey when foraging at night.  This study suggests that reduced colony attendance around the full moon may be linked to greater at-sea foraging opportunities in distant oceanic areas than to increased predation risk on land.”

The United Kingdom’s Seabird Group will celebrate World Albatross Day with ACAP

Seabird Group

The Seabird Group, a registered charity based in the United Kingdom, was founded in 1966 to promote and help coordinate the study and conservation of seabirds.  Three years later, the Seabird Group initiated Operation Seafarer, the first attempt to survey all the UK’s breeding seabird colonies, which was largely delivered through volunteer effort.  It built on this success, working alongside the government agency, the Joint Nature Conservation Committee, to undertake the Seabird Colony Register in 1985 and included Ireland for the first time.  The Group has since been heavily involved with successive censuses, Seabird 2000 and Seabirds Count.  These help us to understand the status of seabirds in the UK, for which it has international responsibilities.

The Group organises regular international conferences and actively supports the participation of early-career scientists.  Members receive regular newsletters and the annual colour journal Seabird, to which they are encouraged to submit material.  The Group actively encourages its members to become involved in surveys of seabirds and other research work Through its grant scheme, the Group has helped to fund seabird research worldwide, from remote islands in Scotland to Portugal and Alaska.  Examples of recent projects include banding studies and census work, at-sea seabird surveys, studies of the impact of light pollution on nocturnal shearwaters and of the migratory movements of terns, and the development of new thermal-imaging techniques to monitor ground-nesting seabirds.

ACAP Latest News reached out to the Seabird Group earlier this year to enlist its support in marking the inauguration of World Albatross Day (‘WAD2020’) on 19 June.  The group's Chair, Liz Humphreys (Senior Research Ecologist at the British Trust for Ornithology) and her Executive Committee colleagues have responded positively, adding the Seabird Group to a growing number of national and international environmental NGOs that will help ACAP celebrate the day, thereby drawing international attention to the conservation crisis facing the world's 22 species of albatrosses.

Liz writes to ALN: “The pioneering research into the foraging behaviour of the Wandering Albatross using satellite technology really highlighted the extraordinary lives these birds lead and the risks they face as they travel around the vast areas of oceans that they roam.  World Albatross Day represents the culmination of many organization’s efforts across the globe, over a number of decades and the Seabird Group is delighted to support this exciting initiative”.

Annette Fayet

The Seabird Group’s Secretary, Annette Fayet (Junior Research Fellow in the University of Oxford’s Department of Zoology) gives her view: “Albatrosses and other seabirds are wonderful and fascinating creatures, but they’re also some of the most endangered birds on Earth.  We must do everything we can to protect them from the multiple threats they face, from invasive species and marine plastic pollution to fisheries bycatch and climate change.  World Albatross Day will help raise awareness of these fantastic birds and their plight”.

Danni Thompson, Membership Secretary and Seabird Ecologist at the UK’s Joint Nature Conservation Committee writes: “With their sheer size, elegance and the ease at which they master the wild oceans, seeing an albatross will always take your breath away.  As top predators they play a fundamental part in the balance of the marine ecosystem, but this is under threat as many seabird populations are in decline due to a myriad of man-made pressures.  World Albatross Day is a great initiative to showcase the beauty and tenaciousness of our most majestic seabirds, and as much as their future depends on us, ours depends on them.”

Katherine Booth Jones, Editor of the Seabird Group Newsletter and Science Officer for Northern Ireland at the British Trust for Ornithology has her say: “Albatrosses are some of the most inspiring birds on the planet and sadly some of the most threatened. World Albatross Day is a fantastic initiative to celebrate these extraordinary masters of the oceans, and most importantly, raise awareness of their fight for survival with people all around the world.”

Saskia Wischnewski, Seabird Group Executive Committee Member (Social Media) and Seabird Conservationist with the UK’s Royal Society for the Protection of Birds Centre for Conservation Science  writes “There is nothing that beats observing these majestic birds in their element and I will never forget spotting my first Wandering Albatross at sea as it soared effortlessly between humongous waves.  Although I’ve never had the chance to work with albatrosses myself, the struggles they face are very similar to the ones that affect our local seabird community.  It’s great to be part of a campaign that celebrates these magnificent creatures while raising awareness of the threats albatrosses and other seabirds encounter all around the world.”
