Short-Tailed Albatross Recovery Plan U.S. Fish and Wildlife Service Short-Tailed Albatross Recovery Plan September 2008 Disclaimer: Recovery plans describe actions which the best scientific information indicates are required to recover and protect listed species. The Endangered Species Act of 1973, as amended, requires Recovery Plans to be prepared for all listed species whose conservation status would benefit by having such a plan. Recovery plans must incorporate: (1) a description of site-specific actions necessary to achieve conservation and survival of the species; (2) objective, measurable criteria, which, when met, would allow removal of the species from the list; and (3) estimates of the time and costs required to implement measures in the plan. Plans are published by the U.S. Fish and Wildlife Service and the NMFS, sometimes prepared with the assistance of recovery teams, contractors, state agencies, and others. The recovery plan is an advisory document. It provides a guide, but it does not obligate any party to carry out the actions it describes. The parties involved will consider their available funds and other priorities when deciding whether to fund the tasks and achieve the objectives presented in this recovery plan. Nothing in this plan should be construed as a commitment or requirement that any agency obligate or pay funds in contravention of the Anti-Deficiency Act, 31 U.S.C. 1341, or any other law or regulation. Recovery plans do not necessarily represent the views or the official positions or approval of any individuals or agencies involved in the plan formulation, other than the U.S. Fish and Wildlife Service. They represent the official position of the Fish and Wildlife Service only after they have been signed by the Regional Director. Approved recovery plans are subject to modification as dictated by new information, changes in species status, and the completion of recovery actions.

  • Waved Albatross Phoebastria Irrorata
    Waved Albatross Phoebastria irrorata Kingdom Animalia Phylum Chordata Class Aves Order Procellariiformes Family Diomedeidae Common Name Waved or Galapagos Albatross, Albatros de las Galapágos Nearest Relatives There are four families and 93 species of albatrosses, storm-petrels, petrels and shearwaters in the order Procellariformes, which means tubenose. All birds in this order have long, hooked, grooved bills with internal “tubes” that aid in expulsion of salt and also contribute to an unusually acute sense of smell. These birds are all highly pelagic, spending most of their time hunting at sea. They are agile fliers and are awkward or unable to walk on land. Procellariformes are closely related to penguins (Sphenisciformes). The waved albatross is the only albatross species found in the Galapagos though there are several species of petrel, storm-petrel and shearwater as well as the Galapagos penguin. They are most closely related to three other species in the genus Phoebastria, the northern pacific albatrosses. Physical Description This is the largest bird in the Galapagos with a wingspan of up to 2.5 meters and weighs up to 4 kg. The back, wings and tail are light to dark brown becoming lighter grey with wavy barring on the breast, hence the name. The head and neck are mostly white with some buffy yellow/orange on the nape. It has a large, yellow, hooked bill. These birds are easily recognizable by their size and may often be seen floating in large groups offshore. Geographic range Many consider the waved albatross to be endemic to the Galapagos; it is found only on Española (Hood) Island.

The Waved Albatross breeds almost exclusively on Isla Española in the Galapagos Archipelago, and its at-sea distribution is restricted to the eastern Pacific Ocean mostly between the Galapagos and the adjacent mainland of South America from central Ecuador to central Peru, but occasionally ranging farther. A decrease in adult survival and a likely reduction in population size have been recently associated with increased mortality from incidental and intentional catch in fisheries. These, together with other potential threats in breeding sites, led to a recent upgrading of the species under the IUCN Red List as Critically Endangered as it is considered to be facing an extremely high risk of extinction in the wild.

Lena Loop Rd, Juneau, AK 99801, USA 3US Fish and Wildlife Service, 1011 E. Tudor Road, Anchorage, AK 99503, USA All three North Pacific albatross species forage in marine waters off Alaska. Despite considerable foraging range overlap, however, the three species do show broad-scale niche segregation. Short-tailed albatross (Phoebastria. albatrus) range most widely throughout Alaska, extensively using the continental shelf break and slope regions of the Bering Sea and Aleutian Archipelago in particular, and the Gulf of Alaska to a lesser extent. Due to small population size, however, short-tailed albatrosses are generally far less prevalent than the other two species. Black-footed albatrosses (P. nigripes) are most abundant in the Gulf of Alaska, and in late summer near some Aleutian passes, occupying foraging habitat similar to short-tailed albatrosses.

  • An Assessment for Fisheries Operating in South Georgia and South Sandwich Islands
    FAO International Plan of Action-Seabirds: An assessment for fisheries operating in South Georgia and South Sandwich Islands by Nigel Varty, Ben Sullivan and Andy Black BirdLife International Global Seabird Programme Cover photo – Fishery Patrol Vessel (FPV) Pharos SG in Cumberland Bay, South Georgia This document should be cited as: Varty, N., Sullivan, B. J. and Black, A. D. (2008). FAO International Plan of Action-Seabirds: An assessment for fisheries operating in South Georgia and South Sandwich Islands. BirdLife International Global Seabird Programme. Royal Society for the Protection of Birds, The Lodge, Sandy, Bedfordshire, UK. 2 Executive Summary As a result of international concern over the cause and level of seabird mortality in longline fisheries, the United Nations Food and Agricultural Organisation (FAO) Committee of Fisheries (COFI) developed an International Plan of Action-Seabirds. The IPOA-Seabirds stipulates that countries with longline fisheries (conducted by their own or foreign vessels) or a fleet that fishes elsewhere should carry out an assessment of these fisheries to determine if a bycatch problem exists and, if so, to determine its extent and nature. If a problem is identified, countries should adopt a National Plan of Action – Seabirds for reducing the incidental catch of seabirds in their fisheries. South Georgia and the South Sandwich Islands (SGSSI) are a United Kingdom Overseas Territory and the combined area covered by the Territorial Sea and Maritime Zone of South Georgia is referred to as the South Georgia Maritime Zone (SGMZ) and fisheries within the SGMZ are managed by the Government of South Georgia and South Sandwich Islands (GSGSSI) within the framework of the Convention on the Conservation of Antarctic Marine Living (CCAMLR).

  • Identification of Infrasonic and Seismic Components of Tremors in Single
    Kurokawa and Ichihara Earth, Planets and Space (2020) 72:171 https://doi.org/10.1186/s40623-020-01302-2 FULL PAPER Open Access Identifcation of infrasonic and seismic components of tremors in single-station records: application to the 2013 and 2018 events at Ioto Island, Japan Aika K. Kurokawa1* and Mie Ichihara2 Abstract Infrasonic stations are sparse at many volcanoes, especially those on remote islands and those with less frequent eruptions. When only a single infrasound station is available, the seismic–infrasonic cross-correlation method has been used to extract infrasound from wind noise. However, it does not work with intense seismicity and sometimes mistakes ground-to-atmosphere signals as infrasound. This paper proposes a complementary method to identify the seismic component and the infrasonic component using a single microphone and a seismometer. We applied the method to estimate the surface activity on Ioto Island. We focused on volcanic tremors during the phreatic eruption on April 11, 2013, and during an unconfrmed event on September 12, 2018. We used the spectral amplitude ratios of the vertical ground motion to the pressure oscillation and compared those for the tremors with those for known signals generated by volcano-tectonic earthquakes and airplanes fying over the station. We were able to identify the infrasound component in the part of the seismic tremor with the 2013 eruption. On the other hand, the tremor with the unconfrmed 2018 event was accompanied by no apparent infrasound. We interpreted the results that the infrasound with the 2013 event was excited by the vent opening or the ejection of ballistic rocks, and the 2018 event was not an explosive eruption either on the ground or in the shallow water.

The diet of winter-breeding Great-winged Petrels Pterodroma macroptera was studied at sub-Antarctic Marion Island, Prince Edward Islands, southern Indian Ocean in August–October 1991 by multiple stomach flushing of weighed chicks after parental feeding. The Great-winged Petrel at Marion Island may be described as a cephalopod specialist, because squid formed the larger part of the diet in terms of diversity, frequency of occurrence and contribution by mass, and were the largest prey items taken. Fish and crustaceans formed relatively minor parts of the diet. These findings are broadly in accord with those of three previous quantitative studies at the same and other localities. Key words: Great-winged Petrel, Pterodroma macroptera, cephalopods, Marion Island, diet INTRODUCTION visited at irregular intervals in the evenings and later at night, and any chicks that had gained at least 10 g because of a parental feed Seabirds are important “top predators” in the Southern Ocean, and over this time period were subjected to multiple stomach-flushing.

  • BYC-08 INF J(A) ACAP: Update on the Conservation Status
    INTER-AMERICAN TROPICAL TUNA COMMISSION SCIENTIFIC ADVISORY COMMITTEE NINTH MEETING La Jolla, California (USA) 14-18 May 2018 DOCUMENT BYC-08 INF J(a) UPDATE ON THE CONSERVATION STATUS, DISTRIBUTION AND PRIORITIES FOR ALBATROSSES AND LARGE PETRELS Agreement on the Conservation of Albatrosses and Petrels (ACAP) and BirdLife International 1. STATUS AND TRENDS OF ALBATROSSES AND PETRELS Seabirds are amongst the most globally-threatened of all groups of birds, and conservation issues specific to albatrosses and large petrels led to drafting of the multi-lateral Agreement on the Conservation of Albatrosses and Petrels (ACAP). A review of the conservation status and priorities for albatrosses and large petrels was recently published in Biological Conservation (Phillips et al. 2016). There are currently 31 species listed in Annex 1 of the Agreement. Of these, 21 (68%) are classified at risk of extinction, a stark contrast to the overall rate of 12% for the 10,694 bird species worldwide (Croxall et al. 2012, Gill & Donsker 2017). Of the 22 species of albatrosses listed by ACAP, three are listed as Critically Endangered (CR), six are Endangered (EN), six are Vulnerable (VU), six are Near Threatened (NT), and one is of Least Concern (LC). Of the nine petrel species, one is listed as CR, one as EN, four as VU, one as NT and two species as LC. The population trends of ACAP species over the last twenty years (since the mid-1990s) were re-examined in 2017 by the ACAP Population and Conservation Status Working Group (PaCSWG). Thirteen ACAP species (42%) are currently showing overall population declines.

  • Feeding Ecology of Short-Tailed Shearwaters: Breeding in Tasmania and Foraging in the Antarctic?
    MARINE ECOLOGY PROGRESS SERIES Published June 18 Mar Ecol Prog Ser l Feeding ecology of short-tailed shearwaters: breeding in Tasmania and foraging in the Antarctic? Henri Weimerskirch*, Yves Cherel CEBC - CNRS, F-79360 Beauvoir, France ABSTRACT- The food, feedlng and physiological ecology of foraging were studied in the short-tailed shearwater Puffinus tenujrostris of Tasmania, to establish whether this species can rely on Antarctic food to fledge its chick. Parents were found to use a 2-fold foraging strategy, on average performing 2 successive short trips at sea of 1 to 2 d duration followed by 1 long trip of 9 to 17 d. These long foraging tnps are the longest yet recorded for any seabird. During short trips the parents tend to lose mass, feed- ing the chick with Australian krill and fish larvae caught in coastal and neritic waters around Tasma- nia. The prey are caught at maximum diving depths of 13 m on average (maximum 30 m).During long trips, adults gain mass and feed their chlcks with a very rich mixture of stomach oil and digested food composed of a high diversity of prey including myctophid fish, sub-Antarctic krill and squids. Prey are probably caught mainly in the Polar Frontal Zone, at least 1000 km south of Tasmania, at maximum depths of 58 m on average (maximum 71 m). Long foraging trips in distant southern waters gave at least twice the yield of trips in close waters but during the former, yield decreased with the time spent for- aging, as indicated by the inverse relationship between time spent forag~ngand adult body condition.
