Individual Grey Petrels exhibit consistent foraging behaviour across years when not breeding

Karine Delord (Centre d'Études Biologiques de Chizé, Villiers-en-Bois, France) and colleagues have published open access in the journal Marine Ornithology on aspects of foraging behaviour of the globally Near Threatened Grey Petrel Procellaria cinerea.

The paper’s abstract follows:

“There is growing interest in the consistency of individual differences in animal behavior as it relates to life history traits and fitness. Despite the relatively large number of studies investigating repeatable behaviors, studies have only recently investigated repeatability in foraging or migratory behaviors, and this has seldom been explored between years. We examined the individual consistency in foraging behavior of the Grey Petrel Procellaria cinerea, a pelagic long-distance migrant. We analyzed how foraging, activity, and migratory patterns were repeatable across different seasons. We used tracking data to monitor the migratory movements and behavior of individuals during the non-breeding period over five years. Despite the small sample size, we found that there was a relatively high individual consistency in wintering strategies across years, with birds displaying high fidelity to their non-breeding destinations during consecutive years. Activity parameters, date of departure of inward migration, duration of migration, and duration spent in non-breeding areas were repeatable as well. The duration of the non-breeding period was the most repeatable, reflecting consistent departure times and, to a lesser extent, consistent arrival times. A high overall repeatability was seen in the timing of the return migration. With respect to sex, males tended to be more consistent in their migration strategy (i.e., timing of migration, time spent in non-breeding areas) than females. Although conditions during the Holocene have generally been stable in the Southern Ocean, species lacking variability in migratory traits are probably at a considerable disadvantage in terms of their capacity to respond to the rapid environment changes currently underway.

BOU John & Pat Warham Studentship for tubenose and penguin research opens for the third time for 2020 applications

The BOU John & Pat Warham Studentship is now open for the third year for a 3.5 year studentship starting between 1 January 2020 and 31 March 2021.  The studentship is funded by the John and Pat Warham Scholarship Fund, a legacy left to the British Ornithologists’ Union (BOU) by the late John and Pat Warham and aims to provide training to PhD level in research on any aspect of the biology or ecology of Sphenisciformes (penguins )and Procellariiformes (tubenoses) by citizens of Commonwealth countries who are also members of the BOU.

John Warham (1919-2010) was one of the pioneers in conducting field research on mainly New Zealand albatrosses and petrels as well as on penguins, publishing two important books on the former group at the end of his long career (click here to read his obituary in ACAP Latest News). His wife Pat helped with field work in their early years together.

Papers for ACAP’s Eleventh Advisory Committee meeting in Brazil next month are now available online

The Eleventh Meeting of ACAP’s Advisory Committee (AC11) will be held over 13-17 May 2019 in Florianópolis, Brazil.  Documents and Information Papers, including a draft agenda (AC11 Doc 01) for the four-day meeting are now available on this web site from where they may be downloaded and consulted.  Note, however, that some documents are password-protected so only their abstracts are publicly available.  For convenience a meeting document (AC11 Doc 05) lists all the papers to be tabled by title and author(s). The meeting will be chaired by Nathan Walker from New Zealand, with Brazil’s Tatiana Neves assisting as Vice-chair.

AC11 will follow the Ninth Meeting of the Seabird Bycatch Working Group (SBWG), and Fifth Meeting of the Population and Conservation Status Working Group (PaCSWG) in the previous week at the same venue, the Jurerê Internacional Il Campanario Hotel.  AC11 will hear summary reports of both these working groups.

The Jurerê Internacional Il Campanario Hotel in in Florianópolis: venue for the Advisory Committee's Eleventh Meeting

On Thursday 16 May AC11 delegates will be given the opportunity to go on all-day boat-based excursion to the Anhatomirim Environmental Protection Area (AEPA).  The 4400-ha area, created in 1992, falls within the IUCN Protected Area Category V (protected landscape/seascape).  It aims to protect biological diversity and ensure the sustainable use of natural resources.  Specific goals include protecting the feeding and breeding areas of the resident population of the globally Endangered Tucuxi Sotalia fluviatilis, a freshwater dolphin, and protecting remnants of Atlantic Rain Forest and survival of local fishing communities.  Globally Vulnerable La Plata River Dolphins or Franciscana Pontoporia blainvillei, Common Bottlenose Dolphins Tursiops truncatus and Southern Right Whales Eubalaena australis,also occur within the AEPA.  Also falling within the AEPA and to be visited on the outing is the 18th-Century Santa Cruz de Anhatomirim Fortress on Anhatomirim Island which forms a part of a suite of 19 coastal fortresses (“Brazilian Fortresses Ensemble”) which was placed on Brazil's Tentative list for World Heritage status in 2015.

Brazil has previously hosted the Agreement; the Second Meeting of the Advisory Committee (AC2) was held in Brasilia in June 2006.  This year’s Advisory Committee and working group meetings follow on from AC10, held in Wellington, New Zealand in September 2017 and the Sixth Session of the Meeting of Parties (MoP6) held in South Africa’s Kruger National Park last year in May.  The Seventh Session (MoP7) is due to be held in 2021 in Australia – when ACAP will be 20 years old.

Florianópolis is the capital and second largest city of the State of Santa Catarina in the southern region of Brazil.  It is served by an international airport.  A coastal city situated on Santa Caterina Island with a humid subtropical climate, it has a population of roughly half a million.  The island is connected to the Brazilian mainland by bridges and is known for its many tourist beaches.

Only three pairs of Wandering Albatrosses are breeding on Macquarie Island this year

Three pairs of globally and nationally Vulnerable Wandering Albatrosses Diomedea exulans are breeding on Australia’s Macquarie Island this current season, according to information received by ACAP Latest News from Tasmania's Department of Primary Industries, Parks, Water and Environment (DPIPWE).

Based on the published literature and previous ACAP Latest News postings, the annual breeding population of Wanderers on Macquarie has fluctuated over the last half a century or so, but with an overall downward trend. With only three pairs currently breeding on Macquarie the population of Wandering Albatrosses is approaching  the smallest known for the species on the island.

Macquarie Island is a World Heritage-status Nature Reserve; its Wandering Albatrosses breed in the most south-westerly part of the island, well away from beaches where tourists are landed.  Their breeding sites around Caroline Cove and Petrel Peak fall within a Special Management Area (Category 1 – Very sensitive area) with ordinarily only researchers monitoring the species being allowed to visit with scientific permits and/or access authorisations from 1 August to 31 May.

With reduced disturbance by strict zonation of the island (and the successful removal of introduced mammals by the Macquarie Island Pest Eradication Project (MIPEP) and its precursors), the main threat to the island’s remaining Wanderers is thought to be interactions of especially pre-breeding birds with tuna longline fisheries on the high seas.

Where do Indian Yellow-nosed Albatrosses from Prince Edward Island go to at sea?

Azwianewi Makhado (Department of Environmental Affairs, Oceans and Coasts Branch, Cape Town, South Africa) and colleagues have published in the journal Emu – Austral Ornithology on the at-sea movements of globally Endangered Indian Yellow-nosed Albatrosses Thalassarche carteri breeding on Prince Edward Island.

The paper’s abstract follows:

“Demographic parameters of wild animals are often closely associated with their foraging distribution and behaviour, and understanding these attributes can assist in identifying causes of population changes. The Indian Yellow-nosed Albatross (Thalassarche carteri) is endangered but little information is available on its at-sea distribution and behaviour. It breeds only in French (Iles Amsterdam, St Paul, Kerguelen and Crozet) and South African (Prince Edward Island, PEI) territories in the south-west Indian Ocean, with PEI supporting about 20% of the global population. This study aimed to investigate the at-sea distributions of adult Indian Yellow-nosed Albatrosses provisioning chicks at PEI and to compare them with distributions of Yellow-nosed Albatrosses breeding at other localities. Using satellite transmitters, we identified two areas that were particularly favoured for foraging. Parents whose partners were brooding small chicks frequently moved north-east of PEI to shallow, productive waters where cold, nutrient-rich water upwells and results in enhanced levels of chlorophyll-a. By contrast, parents with older chicks that could be left unattended often foraged along the Agulhas Bank where eddies and shear forces promote vertical mixing. The at-sea distribution of birds breeding at PEI was located between those reported for Indian Yellow-nosed Albatrosses breeding at Ile Amsterdam and Atlantic Yellow-nosed Albatrosses (T. chlororhynchos) breeding at Gough Island, so that birds from these localities may face different threats at sea. Our study is the first to highlight key feeding areas for Indian Yellow-nosed Albatrosses from PEI and to demonstrate partitioning of foraging grounds by Yellow-nosed Albatrosses from different localities.”
