Studying distribution of Black-footed Albatrosses at sea off California

Pamela Michael (Hawai’i Pacific University at Oceanic Institute, Waimanalo, Hawai'i, USA) and colleagues have published in the on-line/open-access journal PLOS ONE on aspects of the at-sea distribution of Black-footed Albatrosses Phoebastria nigripes.

The paper’s abstract follows:

“At-sea surveys facilitate the study of the distribution and abundance of marine birds along standardized transects, in relation to changes in the local environmental conditions and large-scale oceanographic forcing.  We analyzed the form and the intensity of black-footed albatross (Phoebastria nigripes: BFAL) spatial dispersion off central California, using five years (2004–2008) of vessel-based surveys of seven replicated survey lines.  We related BFAL patchiness to local, regional and basin-wide oceanographic variability using two complementary approaches: a hypothesis-based model and an exploratory analysis. The former tested the strength and sign of hypothesized BFAL responses to environmental variability, within a hierarchical atmosphere—ocean context.  The latter explored BFAL cross-correlations with atmospheric / oceanographic variables. While albatross dispersion was not significantly explained by the hierarchical model, the exploratory analysis revealed that aggregations were influenced by static (latitude, depth) and dynamic (wind speed, upwelling) environmental variables.  Moreover, the largest BFAL patches occurred along the survey lines with the highest densities, and in association with shallow banks. In turn, the highest BFAL densities occurred during periods of negative Pacific Decadal Oscillation index values and low atmospheric pressure.  The exploratory analyses suggest that BFAL dispersion is influenced by basin-wide, regional-scale and local environmental variability. Furthermore, the hypothesis-based model highlights that BFAL do not respond to oceanographic variability in a hierarchical fashion.  Instead, their distributions shift more strongly in response to large-scale ocean—atmosphere forcing.  Thus, interpreting local changes in BFAL abundance and dispersion requires considering diverse environmental forcing operating at multiple scales.”

ACAP wraps up two weeks of meetings in La Serena, Chile today

Friday the 13th is traditionally an inauspicious day but ACAP’s Advisory Committee was pleased to close two weeks of successful meetings in La Serena, Chile today by adopting the final report of its Ninth Meeting (AC9).

Before the report could be adopted elections were required to appoint Chief Officers for the Advisory Committee and its three Working Groups for the next three-year period, which will conclude at the end of the Advisory Committee meeting (AC11), expected to be held in 2019 after the Sixth Session of the Meeting of the Parties in 2018.  Another important decision to be confirmed today is where and when will ACAP meet again, with AC10 due to be held next year.  Watch this space!

To ready themselves for today’s important session, attendees were taken yesterday by our gracious Chilean hosts on an all-day outing inland into the fertile Elqui Valley.  Setting off with what we all thought was a packed lunch of sandwiches and fruit (which was intended to be just a snack, known as padkos – literally "road food" – in South Africa) we ended up sitting down for a splendid three-course lunch in Vicuña’s Terral Hotel & Spa.  Before that we made a visit to the village of Monte Grande in the foothills of the Andes to visit a small museum dedicated to the internationally renowned Chilean poet and diplomat Gabriela Mistral (1889 –1957), who won the Nobel Prize for Literature in 1945 "for her lyric poetry which, inspired by powerful emotions, has made her name a symbol of the idealistic aspirations of the entire Latin American world".  Pablo Neruda, also an internationally recognized Chilean poet (who wrote a poem on the Wandering Albatross entitled Oda a un Albatros Errante) had met Mistral  when he was a teenager.

Following this literary visit the comfortable bus took us to the Tourist Centre and Museum Pisco Capel near the town of Vicuña where we visited the underground museum, the pisco distilling and bottling factory and - for those among us not teetotallers - a tasting bar.  Pisco is described as “a colourless or yellowish-to-amber coloured brandy produced in the wine-making regions of Peru and Chile”.

 

After a group photograph next to an interesting cactus (that came with its own warning not to touch), a short drive took us to the above-mentioned lunch and then back to La Serena for an evening of reading and commenting on the draft AC report.  Before dawn today the report was ready for adoption due to the nocturnal activities of an ever hard-working Secretariat.  Cheers!

Pollutant levels in Critically Endangered Balearic Shearwaters measured

R. Costa (Departamento de Biologia & CESAM, Universidade de Aveiro, Campus de Santiago, Aveiro, Portugal) and colleagues have an in-press paper with the journal Marine Pollution Bulletin that looks at trace element and organic pollutant levels in ACAP-listed and Critically Endangered Balearic Shearwaters Puffinus mauretanicus.

The paper’s abstract follows:

“This study presents the first data on trace element and organic pollutant concentrations in the Critically Endangered Balearic shearwaterPuffinus mauretanicuscollected in 2010 and 2011 in Portugal.  Trace element levels were below the threshold levels for adverse effects on birds, despite the Hg concentrations in feathers (4.35 μg·g–1 ww).  No significant differences were detected between individuals from 2010 and 2011 except for Se concentrations in liver, feathers and muscle (higher in 2010) and Ag in liver and muscle (higher in 2011).  No significant differences were detected in total concentrations of organochlorine compounds in Balearic shearwaters between years, although PCB congeners -101 and -180 presented higher concentrations in individuals from 2010.  The PCB congeners -138, -153 and -180, and 4.4-DDE were detected in all individuals.  This study on toxic elements and organic pollutants in wintering Balearic shearwaters provides baseline data from which deviations can be detected in the future.”

The Advisory Committee decides to compile the ACAP Breeding Site accounts into a single document

To date, 82 illustrated accounts of sites which support a breeding population of at least one ACAP-listed species have been posted to ACAP Latest News since February 2013. All known breeding sites for Argentina, Australia, Ecuador, Mexico, Norway and South Africa have now been covered, including ones with extinct colonies, such as Bouvet Island.

Approximately 50 sites remain to be written up. These include:

Chile: Islas Guafo, Ildefonso, Mocha, Robinson Crusoe and Santa Clara

France: Iles Apôtres, Cochons, de l’Est and Pingouins (Crozet Islands)

Japan: Mukojima (Ogasawara Islands)

New Zealand: Chatham (translocation site), Forty-Fours and Three Kings

Spain: Conills, Espartar, Vedrà and Vedranell (Ibiza, Balearic Islands)

USA: Barking Sands (Kauai), James Campbell Wildlife Refuge (Oahu; translocation site), French Frigate Shoals, Gardner Pinnacles, Lisianski, Ka’ula, Necker, Niihau and Pearl & Hermes Reef

Disputed Territories: Remaining individual islands in the Falkland Islands (Islas Malvinas)*, South Georgia (Islas Georgias del Sur)* and the Senkaku Islands

Antarctic Continent: Remaining colonies of Southern Giant Petrels Macronectes giganteus on and around the Antarctic Peninsula

On the second day of its meeting in La Serena, Chile ACAP’s Advisory Committee adopted the report of its Population and Conservation Status Working Group (PaCSWG3), which met last week.  The Advisory Committee agreed with its working group that the above and any other identified sites be written up under the guidance of ACAP’s Information Officer, John Cooper and posted to ACAP Latest News by the time of the Tenth Meeting of the Advisory Committee (AC10) next year.

During the PaCSWG meeting offers of help with compiling the outstanding site descriptions came from Patricia Pereira Serafini (Brazil, for Southern Giant Petrels on the Antarctic Peninsula), Verónica López (Chile, Pink-footed Shearwater Puffinus (Ardenna) creatopus), Juan Pablo Seco-Pon (Argentina), Sally Poncet (Falkland Islands (Islas Malvinas)*) and South Georgia (Islas Georgias del Sur)*), Igor Debski (New Zealand), Cristián Suazo (Chile; albatross colonies), Amanda Kuepfer (Falkland Islands (Islas Malvinas)*) and Beth Flint (USA; Hawaiian Islands).  French marine ornithologists will be approached seeking support for the outstanding accounts for their sub-Antarctic islands, and, of course, any other volunteers willing to be involved will be welcomed. J.M. "Pep" Arcos of Spain is currently drafting the remaining Spanish accounts for the Balearic Shearwater Puffinus mauretanicus.

Each breeding site account normally includes:

1. A brief description of the locality with its name, locality, size, habitat and vegetation,

2. Information on breeding ACAP-listed species: names, numbers, trends and monitoring efforts,

3. Conservation status: management plan, nature reserve, Important Bird Area and World Heritage Site status and alien control/eradication efforts past, present or planned,

4. Up to 10 or so selected references, and

5. Five to eight photographs with captions showing the locality, its habitats, colonies and ACAP species.

Once the outstanding accounts have been written it is intended that the earlier ones will be updated where necessary and all will be brought together into a single document.  It is expected that AC10 will then discuss quite how best to publish an ACAP breeding sites compilation.
