  • Disaggregation of Bird Families Listed on Cms Appendix Ii
    Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1. Through Resolution 11.19, the Conference of Parties adopted as the standard reference for bird taxonomy and nomenclature for Non-Passerine species the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World, Volume 1: Non-Passerines, by Josep del Hoyo and Nigel J.

  • Western Shore of Admiralty Bay, King George Island, South Shetland Islands
    Measure 4 (2014) Annex Management Plan for Antarctic Specially Protected Area No 128 WESTERN SHORE OF ADMIRALTY BAY, KING GEORGE ISLAND, SOUTH SHETLAND ISLANDS Introduction The Western Shore of Admiralty Bay is located on King George Island, South Shetland Islands, ~125 kilometers from the northern Antarctic Peninsula. Approximate area and coordinates: 16.8 km2 (centered at 58° 27' 40" W, 62° 11' 50" S). The Area is wholly terrestrial, and the primary reasons for designation are its diverse avian and mammalian fauna and locally rich vegetation, providing a representative sample of the maritime Antarctic ecosystem. Long term scientific research has been conducted on the animals within the Area. The Area is relatively accessible to nearby research stations and tourist ships regularly visit Admiralty Bay, and the ecological and scientific values of the area need protection from potential disturbance. The Area was originally designated as Site of Special Scientific Interest (SSSI) No. 8 in Recommendation X-5 (1979, SSSI No. 8) after a proposal by Poland. The SSSI designation was extended through Recommendation XII-5 (1983), Recommendation XIII-7 (1985) and Resolution 7 (1995). A revised Management Plan was adopted through Measure 1 (2000). The site was renamed and renumbered as Antarctic Specially Protected Area (ASPA) No 128 by Decision 1 (2002). The Area lies within Antarctic Specially Managed Area (ASMA) No. 1 Admiralty Bay, King George Island, South Shetland Islands, designated under Measure 2 (2006). The biological and scientific values of the Area are vulnerable to human disturbance (e.g. oversampling, disturbance to wildlife, introduction of non-native species). Therefore, it is important that human activities in the Area are managed to minimize the risk of impacts.

  • Parallel Evolution in the Major Haemoglobin Genes of Eight Species of Andean Waterfowl

However, confirmation is scarce in natural populations. Here we studied the major haemoglobin genes of eight Andean duck lineages and compared them to 115 other waterfowl species, including the bar-headed goose (Anser indicus) and Abyssinian blue-winged goose (Cyanochen cyanopterus), two additional species living at high altitude. One to five amino acid replacements were significantly overrepresented or derived in each highland population, and parallel substitutions were more common than in simulated sequences evolved under a neutral model. Two substitutions evolved in parallel in the aA subunit of two (Ala-a8) and five (Thr-a77) taxa, and five identical bA subunit substitutions were observed in two (Ser-b4, Glu-b94, Met-b133) or three (Ser-b13, Ser-b116) taxa.

During extreme excitement the male will often roll his head on his back, or even bathe. I have not observed Preening-behind-the- wing, but W. von de Wall (pers. comm.) has observed a male per- form it toward a female. Finally, Wing-flapping appears to be used as a display by males, and it is especially conspicuous because each sequence of it is ended by a rapid stretching of both wings over the back in a posture that makes visible the white axillary feathers, which contrast sharply with the black underwing surface. Copulatory behavior. Precopulatory behavior consists of the male swimming up to the female, his neck stretched and his crest de- pressed, and making occasional Bill-dipping movements. He then suddenly begins to perform more vigorous Head-dipping movements, and the female, if receptive, performs similar Bill-dipping or Head- dipping movements.

Scientific rationale and objectives The inshore marine systems and resources of the Falkland Islands make up one of the nation’s most diverse, unique, and valuable assets. From its historical reputation as a safe harbour to its present dependence on fishing and wildlife-based revenues, this archipelago is defined by the sea and its resources. Though perhaps best known ecologically for its bird life, the islands hold numerous organisms and environments that are all closely linked. Of the ten bird species of global conservation concern that breed within the Falklands, eight are seabirds and two are closely associated with offshore islands that contain seabird colonies. These species rely on the marine productivity of the waters around the Falkland Islands and in turn cycle nutrients among the soils, plants, and invertebrates of coastal areas. Knowledge and management of the marine environments are thus important for the knowledge and management of all Falklands ecosystems. Surprisingly, very little of the Islands’ immense coastline has been the subject of scientifically sound investigation, and identification of shallow marine species and habitat types is still in its infancy.
