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.

Oromia is the largest National Regional State of Ethiopia. Here we present the first comprehensive checklist of its birds. A total of 804 bird species has been recorded, 601 of them confirmed (443) or assumed (158) to be breeding birds. At least 561 are all-year residents (and 31 more potentially so), at least 73 are Afrotropical migrants and visitors (and 44 more potentially so), and 184 are Palaearctic migrants and visitors (and eight more potentially so). Three species are endemic to Oromia, 18 to Ethiopia and 43 to the Horn of Africa. 170 Oromia bird species are biome restricted: 57 to the Afrotropical Highlands biome, 95 to the Somali-Masai biome, and 18 to the Sudan-Guinea Savanna biome. -
An Introduction to the Bofedales of the Peruvian High Andes
An introduction to the bofedales of the Peruvian High Andes M.S. Maldonado Fonkén International Mire Conservation Group, Lima, Peru _______________________________________________________________________________________ SUMMARY In Peru, the term “bofedales” is used to describe areas of wetland vegetation that may have underlying peat layers. These areas are a key resource for traditional land management at high altitude. Because they retain water in the upper basins of the cordillera, they are important sources of water and forage for domesticated livestock as well as biodiversity hotspots. This article is based on more than six years’ work on bofedales in several regions of Peru. The concept of bofedal is introduced, the typical plant communities are identified and the associated wild mammals, birds and amphibians are described. Also, the most recent studies of peat and carbon storage in bofedales are reviewed. Traditional land use since prehispanic times has involved the management of water and livestock, both of which are essential for maintenance of these ecosystems. The status of bofedales in Peruvian legislation and their representation in natural protected areas and Ramsar sites is outlined. Finally, the main threats to their conservation (overgrazing, peat extraction, mining and development of infrastructure) are identified. KEY WORDS: cushion bog, high-altitude peat; land management; Peru; tropical peatland; wetland _______________________________________________________________________________________ INTRODUCTION organic soil or peat and a year-round green appearance which contrasts with the yellow of the The Tropical Andes Cordillera has a complex drier land that surrounds them. This contrast is geography and varied climatic conditions, which especially striking in the xerophytic puna.

Spectacled Eiders He Spectacled Eider Is Truly a Breed Apart
WILDLIFE AND GLOBAL WARMING Navigating the Arctic Meltdown © GARY KRAMER/GARY KRAMER.NET SPECTACLED EIDERS he spectacled eider is truly a breed apart. A diving duck named for its distinctively T“spectacled” appearance, the eider spends much of the year in places so remote that its wintering grounds were only discovered in 1999, with the help of space-age satellite tracking. With its American population decimated by poisoning from ingesting lead shot, the eider was listed as a threatened species in 1993. Now global warming poses an additional peril to this unique bird, with the potential to alter both the eiders’ breeding and wintering habitats. A Rare Bird Pacific; more nutrients are flushed into the shallow seas by The spectacled eider is a medium-sized sea duck, slightly Alaska’s great river systems.

E-mail: [email protected] 2Instituto de Ciencias Marinas y Limnológicas, Facultad de Ciencias, Universidad Austral de Chile, Valdivia, Chile. Resumen. – Biología reproductiva y comportamiento del Cisne de Cuello Negro (Cygnus melano- coryphus). – El cisne de cuello negro (Cygnus melanocoryphus) es la única especie del género Cygnus que habita en Sudamérica. Si bien, el resto de las especies del género han sido extensamente estudia- das, para C. melanocoryphus aún no se ha descrito la mayor parte de su biología reproductiva. En este estudio evaluamos el comienzo y extensión de la temporada reproductiva, y el tamaño de nidada utili- zando datos recolectados en el Santuario Carlos Anwandter (SCA), Valdivia, Chile; correspondientes a 18 temporadas reproductivas. Por otro lado, estudiamos el comportamiento de las parejas durante el periodo de incubación, durante una temporada reproductiva. Se estimó el presupuesto de tiempo y dis- tancia con respecto al nido en seis parejas nidificantes. El periodo de nidificación se puede extender desde junio a enero y está influenciado por el tamaño de la población reproductiva y las condiciones cli- máticas. El tamaño de nidada se mantiene constante con una moda de tres huevos (promedio 3.13 ± 0.017; n = 5897). Ambos miembros de la pareja desarrollan actividades de vigilancia y mantención del nido, sin embargo, la incubación es una tarea exclusiva de la hembra, mientras que la defensa activa del nido es realizada por el macho. -

Australian Wood Duck (Chenonetta Jubata)
Australian Wood Duck (Chenonetta jubata) Also known as the ‘Maned Duck’ or ‘Maned Goose’ QUICK FACTS Male Australian Wood Duck • They are nicknamed ‘Maned Goose’ because people think they look more like miniature geese than ducks. • Wood Ducks love heavy rainfall because this is when the tastiest bugs emerge. They also love laying eggs after heavy rain. • They are better adapted to walking than swimming or diving. Length: Weight: 44–50cm 700–955g Identification: Female Australian Wood Duck The Australian Wood Ducks have earnt the nickname ‘Maned Goose’ because of their very goose-like appearance. The feathers around their neck and breast also give the impression of a lion’s mane. In flight, Australian Wood Ducks’ wings come out on show. Their wing tips are black and their wings are a pale grey with a white bar on the underside of the wing. Like many ducks, male and female Australian Wood Ducks vary in size and appearance. Males tend to have a darker head and smaller mane with speckled brown-grey bodies, a black undertail and black lower belly. Females have paler heads with white stripes above and below their eyes. Their breast and flanks are also speckled with a white undertail and white lower belly. BEHAVIOUR DISTRIBUTION & HABITAT Unlike most ducks, Australian Wood Ducks do not favour Australian Wood Ducks are found across most of Australia. swimming and will only enter open water if they’re Flocks of hundreds of birds can be found gathering disturbed. Instead, they prefer to waddle around and graze in southern areas of Australia in autumn and winter.
