UPDATED. Fourth International Forum on the sub-Antarctic to be held in Hobart, Australia, June 2020

UPDATE

Registration will open in January 2020.

During the 11th Meeting of ACAP's Advisory Committee meeting in Brazil this week, delegates and observers were informed of upcoming conferences of relevance to seabird biology and conservation.  The Australian Delegation reported on the intention to host a two-day conference on sub-Antarctic islands, homes to many ACAP-listed species, next year.  Details follow.

 The Tasmanian Government of Australia will join with the New Zealand Department of Conservation to host the Fourth International Forum on the sub-Antarctic in Hobart, Tasmania over 29-30 July 2020.

 

“The Forum will be multidisciplinary, interactive and inclusive, encouraging discussion of the common challenges and pressures that face the sub-Antarctic.  It will bring together all those passionate about the sub-Antarctic - scientists, tourism operators, fishers, land managers, heritage experts and policy makers - to share knowledge and experience, explore connections and develop partnerships for a collective future.”

Within the overarching themes of policy, management and science, the Forum will include sessions on climate, conservation, biosecurity, geoscience, tourism, fishing, heritage connectivity, and management challenges.

Immediately after the Sub-Antarctic Forum, Hobart will host the 2020 Scientific Committee on Antarctic Research (SCAR) Open Science Conference and the SCAR Delegates Meeting.  Click here for SCAR’s first pre-conference circular.

“A Black-footed Albatross was found entangled in discarded balloons and strings on Marina State Beach in June 2013”

Erica Donnelly-Greenan (Moss Landing Marine Laboratories, Moss Landing, California, USA) and colleagues have published in the Marine Pollution Bulletin on surveys of entangled seabirds on the coast of California.  Sooty Shearwaters Ardenna grisea made up 8%.  A few Arctic or Northern Fulmars Fulmarus glacialis were also reported, as was a Black-footed Albatross Phoebastria nigripes entangled with a balloon.

The paper’s abstract follows:

“Marine fauna in the California Current System is susceptible to entanglement in anthropogenic debris.  We examined beach survey data from six California counties to describe trends of entangled marine birds and mammals (1997–2017). Surveyors reported 357 cases of entanglements among 65,604 carcasses. Monterey County had the greatest average entanglement rate (0.007) of surveyed counties, however, was not statistically different from Santa Cruz (p > 0.05). Twenty-six seabird species (97%) and three marine mammal species (3%), and three non-marine birds were affected. Numerically, Common Murre (23%), Brandt's Cormorant (13%), Western Gull (9.6%), Sooty Shearwater (8%) and Brown Pelican (7%) were the most affected due to abundance, but their entanglement rates were not statistically different (p > 0.05). The most vulnerable species were those frequently documented as entanglement despite low deposition numbers (Merganser spp. 25%). Entangling material consisted primarily of monofilament line (some hooks/lures), but other entanglement items were reported.”

At-sea mortality of Atlantic Yellow‐nosed Albatrosses is related to storms off Brazil

Davi Tavares (Department of Theoretical Ecology and Modelling, Leibniz Centre for Tropical Marine Research, Bremen, Germany) and colleagues have published open access in the journal Animal Conservation on at-sea mortality of three seabird species based on stranding data, including of the ACAP-listed and globally Endangered Atlantic Yellow‐nosed albatross Thalassarche chlororhynchos.

The paper’s abstract follows:

“Large‐scale climatic processes such as the El Niño‐Southern Oscillation (ENSO) can have severe effects on the survival of seabirds in their breeding regions. However, there is a fundamental lack of understanding about how environmental factors are related to the mortality of these organisms in non‐breeding areas of the tropics. We investigate here the direct and indirect effects of ENSO and oceanographic variables on the mortality of three migratory seabird species targeted by conservation programmes focused on human impacts: the Atlantic yellow‐nosed albatross Thalassarche chlororhynchos, the Magellanic penguin Spheniscus magellanicus and the Manx shearwater Puffinus puffinus in a non‐breeding area in Brazil, tropical Atlantic. We find that the intensification of ENSO increases the mortality of Manx shearwaters by enhancing the local storm activity. The mortality of Atlantic yellow‐nosed albatrosses and Magellanic penguins is also related to a local increase in storm activity but regardless of the ENSO signature. Increased mortality of Magellanic penguins is observed when biological productivity falls below the annual average (1.7 mg m−3). Adverse climatic conditions are highly deleterious for migratory seabirds and single storm episodes can cause massive deaths, thus exacerbating population declines. We argue that conservation and management strategies for migratory seabirds studied here should not only focus on direct human impacts but should also consider mitigating the effects of climate variability.”

Studying albatross behaviour around fishing vessels with radar

Alexandre Corbeau (Centre d’Études Biologiques de Chizé, Villiers en Bois, France) and colleagues have published open access in the journal PLoS ONE on using GPS loggers on globally Vulnerable Wandering Albatrosses Diomedea exulans to detect fishing vessels via Radar.

The paper’s abstract follows:

“Seabirds are well known to be attracted by fishing boats to forage on offal and baits. We used recently developed loggers that record accurate GPS position and detect the presence of boats through their radar emissions to examine how albatrosses use Area Restricted Search (ARS) and if so, have specific ARS behaviours, when attending boats. As much as 78.5% of locations with a radar detection (contact with boat) during a trip occurred within ARS: 36.8% of all large-scale ARS (n = 212) and 14.7% of all small-scale ARS (n = 1476) were associated with the presence of a boat. During small-scale ARS, birds spent more time and had greater sinuosity during boat-associated ARS compared with other ARS that we considered natural. For, small-scale ARS associated with boats, those performed over shelves were longer in duration, had greater sinuosity, and birds spent more time sitting on water compared with oceanic ARS associated with boats. We also found that the proportion of small-scale ARS tend to be more frequently nested in larger-scale ARS was higher for birds associated with boats and that ARS behaviour differed between oceanic (tuna fisheries) and shelf-edge (mainly Patagonian toothfish fisheries) habitats. We suggest that, in seabird species attracted by boats, a significant amount of ARS behaviours are associated with boats, and that it is important to be able to separate ARS behaviours associated to boats from natural searching behaviours. Our study suggest that studying ARS characteristics should help attribute specific behaviours associated to the presence of boats and understand associated risks between fisheries.”

Possession and Marion: two more sub-Antarctic islands support next year’s inaugural World Albatross Day with banners

Two more sub-Antarctic islands have joined ACAP’s “World Albatross Day Banner Challenge”, both in the southern Indian Ocean.  These are France’s Possession Island in the Crozets group, and South Africa’s Marion Island, the larger of the two in the Prince Edward Islands.  Both islands are inhabited by teams from their national Antarctic programmes, TAAF and SANAP, and include marine ornithologists who are studying the islands’ breeding seabirds, including ACAP-listed and globally threatened albatrosses.

Possession and Marion join three other sub-Antarctic islands which had already made and photographed their home-made World Albatross Day banners in the field;   Bird (here) and Gough (here) Islands in the South Atlantic, and France’s Amsterdam Island (here) in the southern Indian.

On Possession the island’s ornithologist kindly organized the ‘WAD Banner’ and display.  He writes to ACAP Latest News: “I’m Florent Lacoste, CEBC-CNRS of Chizé, program 109.  I'm a VSC (Volontariat en Service civique) and I'm here to monitor different species of birds and marine mammals.  We [are] monitoring 14 species in Crozet: albatrosses (x3), petrels (x3), penguins (x4), fur seal (x2), southern elephant seal, killer whale.  We also study alimentary strategies and repartition [distribution] of these marine predators.  My field job is to put GPS, to ring, to take pictures for photo-identification (killer whale), to count penguin colonies, etc. …”.  Florent is clearly busy with this work load so ACAP is especially grateful to him and to his colleagues for contributing to the banner challenge!

A thousand-odd kilometres to the west doctoral student Stefan Schoombie on Marion Island also gave up his time to make a banner with his colleagues.  Short of a suitable cloth an old black-out blind was used instead to give a different look.  Stefan shares his views on World Albatross Day:

“Albatrosses are seldom seen by most, but are all so important to our oceans, never mind being among the most majestic of birds.  World Albatross Day is a great initiative to highlight the conservation crisis that these birds are facing."  Stefan is in his third year on the island where he conducted his MSc research on population dynamics and distribution of Phoebastria albatrosses in 2013/14 (M70), and 2015/16 (M72).  Now a member of the M76 Team, his Ph.D. research is entitled “Remotely sensing motion: the use of multiple technologies to detect fine-scale behaviour of breeding seabirds in a variable environment” through the FitzPatrick Institute of African Ornithology at South Africa’s University of Cape Town.  His field research is concentrating on Wandering Albatrosses Diomedea exulans this time.

More southern island banner photographs are expected as the summer breeding seasons get underway.  Following ACAP’s outreach, promises have come from elsewhere in the Southern Ocean: Australia’s Macquarie Island, for several New Zealand sub-Antarctic island groups, from France’s Kerguelen and from researchers based in the Falkland Islands (Islas Malvinas)*.  In the Northern Hemisphere it is hoped banners will be displayed on up to three of the USA’s Hawaiian Islands and on two islands belonging to Japan.  These banner displays in island breeding colonies around the world will all help raise awareness of what is intended to be an annual event: World Albatross Day on 19 June.

With thanks to Florian Lacoste and Stefan Schoombie for information and photographs.
