Looking a little odd for the camera: hybrid Black-Footed and Laysan Albatrosses illustrated

Cameron Rutt (Blooming Glen, Pennsylvania, USA) writes in the journal Western Birds on hybridization in the Black-Footed Phoebastria nigripes and Laysan P. immutabilis Albatrosses.  Nice pics, including of birds flying and on the sea.

The paper’s abstract follows:

“Although the Laysan (Phoebastria immutabilis) and Black-footed Albatrosses (P. nigripes) have been known to hybridize for more than a century, little has been published regarding plumage variation of the hybrid progeny.  During six months of field work on Laysan, Hawaii, I noted 13 possible hybrids (five presumed F1 hybrids, three possible F2 backcrosses with the Black-footed Albatross, and at least four possible F2 backcrosses with the Laysan Albatross).  Apparent F2 backcrosses with the Black-footed Albatross differ from it most noticeably in their black-and-white underwings and much more extensive white circling the face.  Apparent F2 backcrosses with the Laysan Albatross differ from that species most noticeably in their extensive gray smudging throughout the body and darker underwing coverts.  Apparent F2 backcrosses interbreed with the Black-footed Albatross, the first evidence of any hybrid pairing with that parental species.”

Getting older, getting colder: male Wandering Albatrosses forage south as they age

Audrey Jaeger (Centre d'Etudes Biologiques de Chizé, France) and colleagues, publishing in the journal Ecology, look at changes in the foraging zones utilized by Wandering Albatrosses Diomedea exulans as they age.

The paper’s abstract follows:

“Evidence of age-dependent changes in foraging behavior of free-ranging individuals is scarce, especially at older stages.  Using the isotopic niche as a proxy of the trophic niche during both the breeding (blood) and inter-nesting (feather) periods, we report here empirical evidence for age-, gender- and breeding status-dependent foraging ecology and examine its potential consequences on subsequent reproduction and survival in an extremely long-lived species, the wandering albatross.  Immature wandering albatrosses of both sexes forage in the subtropics (δ13C) and feed at the same trophic position (δ15N) than the adults.  In contrast to immature birds, adult females forage on average at northern latitudes than males, with both sexes feeding in the subtropics during the inter-nesting period, and males, not females, favouring subantartic [sic] waters during incubation.  In contrast to adult females, males showed a unique pattern among birds and mammals of a continuous change with age in their main feeding habitat by foraging progressively further south in colder waters during both the breeding and inter-nesting periods.  In males, foraging at higher latitudes (lower feather δ13C values) is associated with a lower probability to breed during the following years compared to other birds, but with no effect on their probability to survive.  Foraging in cold and windy waters may be linked to foraging impairment that might explain different life history trade-offs and lower investment in reproduction with age.  This key point requires further longitudinal investigations and/or studies examining foraging success and energy budget of birds feeding in different water masses.”

A Chilean workshop discusses the achievements and progress of the National Plan of Action for the Pink-footed Shearwater

The Vulnerable Pink-footed Shearwater Puffinus creatopus, a Chilean breeding endemic species, breeds on Mocha and Juan Fernández Islands off central Chile (click here).  The species is a transequatorial migrant reaching western North America including the Gulf of Alaska and southern Bering Sea.

International concern about the species is reflected in its recent listing as Threatened by the Committee on the Status of Endangered Wildlife (COSEWIC) in Canada and as of Common Concern by the Canada/Mexico/U.S. Trilateral Committee.  This has triggered several site-specific Conservation Plans for the species. In Chile, the Corporación Nacional Forestal (National Forestry Corporation) developed a National Plan of Action for the Pink-footed Shearwater in 2007.

A workshop was held in Valparaíso in the Instituto de Fomento Pesquero (Fisheries Development Institute) on 15 January.  The workshop’s main goal was to assess the status of the Chilean National Plan of Action for the Pink-footed Shearwater and share the state of knowledge for the species by reviewing the main activities implemented for addressing threats both on land and at sea.

The workshop was led by Marcelo García (Subsecretaría de Pesca y Acuicultura de Chile) and Jorge Azócar (Instituto de Fomento Pesquero) with the participation of Charif Tala and Sandra Diáz (Ministerio de Medio Ambiente de Chile), Moises Grimber, Javier Meza and Guillermo Reyes (Corporación Nacional Forestal), Peter Hodum, Valentina Colodro and Verónica Lopez (Oikonos), Holly Freifeld (American Bird Conservancy), Erin Hagen (Island Conservation), and Luis Cabezas (BirdLife Albatross Task Force Chile).

The discussions resulted in a schedule of activities which will have the dual purpose of developing the National Plan of Action based on the new scheme of the Chilean institutions and progressing the incorporation of the Pink-footed Shearwater into Annex 1 of the Agreement on the Conservation of Albatrosses and Petrels (click here).

A second meeting is due to be held in April this year at the Instituto de Fomento Pesquero.

“Shy-type” albatrosses attending trawlers in the south-western Atlantic: updating at-sea records and their interaction with fisheries

Shy Thalassarche cauta and White-capped T. steadi Albatrosses are two taxa for which specific status has recently been postulated; however, owing to their close morphological resemblance they are frequently referred to as “shy-type” albatrosses.  White-capped Albatross, a New Zealand breeding endemic, is well known in South American seas, particularly in the Humboldt Current.  Conversely, Shy Albatross, an Australian breeding endemic, is less pelagic than many other albatrosses, although its range extends to southern Africa.  Both albatross species are listed as Near Threatened, due to their high mortality rates as a result of interactions with longline and trawl fisheries in southern Indian and south-eastern Atlantic Oceans.

Shy-type albatrosses have been previously recorded in the south-western Atlantic region in Brazilian waters, and later on onto the north and north-west of the Falkland Islands (Islas Malvinas)*.  However, these records do not come from observations made on board fishing vessels or from land-based interviews with fishers.  Birds, chiefly juvenile and non-breeding adults, have been recently recorded interacting with commercial longline fisheries off the Argentine-Uruguayan Common Fishing Zone and being caught by this fishery as well as off southern Brazil.

More recently, shy-type albatrosses have been recorded attending high-seas trawlers in Patagonian waters off Argentina.  Over the period 2008 to 2011 22 sightings of shy-type albatrosses comprising up to 49 individuals were made from these trawlers, chiefly between 39ºS to 44°S and 55ºW to 60ºW.  The records collated so far indicate (1) that shy-type albatrosses may be more widely distributed in the region that previously thought, and (2) that the Patagonian Shelf may be an important foraging area for these species.

The support of ACAP Parties such as Argentina, Brazil, Uruguay and the United Kingdom in conducting at-sea surveys has enabled a better understanding of the global ranges of threatened or potentially threatened species of albatrosses and petrels and this work needs to be continued as our knowledge of many species’ foraging ranges is still incomplete.

The South Pacific Regional Fisheries Management Organisation adopts a measure to mitigate seabird bycatch in longline and trawl fisheries

The Second Commission Meeting of the South Pacific Regional Fisheries Management Organisation (SPRFMO) was held last month in Manta, Ecuador (click here).  ACAP was represented at the meeting by its Executive Secretary, Warren Papworth.

A conservation and management measure (COMM-02-08) for minimising the bycatch of seabirds in the SPRFMO convention area was proposed for consideration at the meeting by the Government of New Zealand.

The Commission subsequently adopted a conservation and management measure (CMM 2.04) based on the New Zealand proposal (click here for the meeting’s report).  CMM 2.04 substantially reflects ACAP’s best-practice advice for minimising seabird bycatch in demersal longline and trawl fisheries and the adoption of this CMM by the SPRFMO Commission is warmly welcomed.

The Commission also requested its Secretariat to explore the possibility of a memorandum of understanding on data exchange with ACAP.

The South Pacific Regional Fisheries Management Organisation is an intergovernmentalorganisation committed to the long-term conservation and sustainable use of the fishery resources of the South Pacific Ocean and in so doing safeguarding the marine ecosystems in which the resources occur.
