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.

Changes to Category C of the British List†
Ibis (2005), 147, 803–820 Blackwell Publishing, Ltd. Changes to Category C of the British List† STEVE P. DUDLEY* British Ornithologists’ Union, Department of Zoology, University of Oxford, South Parks Road, Oxford OX1 3PS, UK In its maintenance of the British List, the British Ornithologists’ Union Records Committee (BOURC) is responsible for assigning species to categories to indicate their status on the List. In 1995, the British Ornithologists’ Union (BOU) and the Joint Nature Conservation Committee (JNCC) held a conference on naturalized and introduced birds in Britain (Holmes & Simons 1996). This led to a review of the process of establishment of such species and the terms that best describe their status (Holmes & Stroud 1995) as well as a major review of the categorization of species on the British List (Holmes et al. 1998). The BOURC continues to review the occurrence and establishment of birds of captive origin in Britain. This paper sum- marizes the status of naturalized and introduced birds in Britain and announces changes to the categorization of many on the British List or its associated appendices (Categories D and E): Mute Swan Cygnus olor Categories AC change to AC2 Black Swan Cygnus atratus Category E* – no change Greylag Goose Anser anser Categories ACE* change to AC2C4E* Snow Goose Anser caerulescens Categories AE* change to AC2E* Greater Canada Goose Branta canadensis Categories ACE* change to C2E* Barnacle Goose Branta leucopsis Categories AE* change to AC2E* Egyptian Goose Alopochen aegyptiacus Categories CE* change -
What Makes a Good Alien? Dealing with the Problems of Non-Native Wildfowl Tony (A
What makes a good alien? Dealing with the problems of non-native wildfowl Tony (A. D.) Fox Mandarin Ducks Aix galericulata Richard Allen ABSTRACT Humans have been introducing species outside their native ranges as a source of food for thousands of years, but introductions of wildfowl have increased dramatically since the 1700s.The most serious consequence of this has been the extinction of endemic forms as a result of hybridisation, although competition between alien and native forms may also contribute to species loss. Globally, non-native wildfowl have yet to cause major disruption to ecosystem functions; introduce new diseases and parasites; cause anything other than local conflicts to agricultural and economic interests; or create major health and safety issues in ways that differ from native forms. The fact that this has not happened is probably simply the result of good fortune, however, since many introduced plants and animals have had huge consequences for ecosystems and human populations.The potential cost of greater environmental and economic damage, species extinction, and threats to the genetic and species diversity of native faunas means that we must do all we can to stop the deliberate or accidental introduction of species outside their natural range. International legislation to ensure this is remarkably good, but domestic law is generally weak, as is the political will to enforce such regulations.The case of the Ruddy Duck Oxyura jamaicensis in Europe will show whether control of a problem taxon can be achieved and underlines the financial consequences of dealing with introduced aliens.This paper was originally presented as the 58th Bernard Tucker Memorial Lecture to the Oxford Ornithological Society and the Ashmolean Natural History Society, in November 2008. -
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. -

Notes on Some Argentine Anatids
NOTESON SOME ARGENTINEANATIDS' MILTON W. WELLER ROM mid-August, 1964, until late July, 1965, I was engaged in field work F in Argentina studying waterfowl. Although special emphasis was placed on the Black-headed Duck (Heteronetta atricapilla) , 28 species of anatids were observed in various parts of Argentina. Because so little is known of these species, some general observations are summarized and discussed in the hope that it will point out gaps in our knowledge and encourage additional work on this interesting group. Field work was financed by Grant GB-1067 from the National Science Foundation. Studies of museum specimens in the United States were financed by a Chapman Grant of the American Museum of Natural History, and aided materially in appraising the significance of plumage sequences in Neotropical ducks. AQUATIC HABITATS Although the distribution of Argentine birds was considered by Dabbene (1910) and by Olrog (19591, little comment has been made on the distribution of water types and their influence on waterfowl distribution. Some helpful botanical comments are given by Cabrera (1953) for the Buenos Aires region and, Wetmores’ (1926) observations on both botany and ornithology are excellent. Although time did not permit detailed botanical work during this study, some obvious differences in life-form of marsh vegetation were recorded in the areas visited (Fig. 1) in relation to the species composi- tion of waterbirds. The most extensive zone of freshwater and semipermanent marshes is found in an area roughly bordered by the cities of Venado Tuerto (Santa Fe), Buenos Aires, General Lavalle, Mar de1 Plats and Azul (Buenos Aires). -
The Birds of Wimbledon Common and Putney Heath 2015
The Birds of Wimbledon Common and Putney Heath 2015 Male Wheatear on the log pile 1 The Birds of Wimbledon Common and Putney Heath 2015 The Birds of Wimbledon Common and Putney Heath 2015 espite coverage on the Common being rather poor again this year, a total of 96 species were D recorded, four more than in 2014. Of these, 45 bred or probably bred, with no doubt the highlight of the year being the successful breeding of a pair of Skylarks on the Plain, the first to do so since 2007. Much credit for this achievement must go to Wildlife & Conservation Officer, Peter Haldane, and his staff, who have persevered over the years to create a suitable and safe habitat for this Red-listed bird. Credit is also due to Chief Executive, Simon Lee, for his valuable cooperation, and indeed to the vast majority of the visiting public, many of whom have displayed a keen interest in the well-being of these iconic birds. Signage on the Plain this year was extended to the two uncut sections during the autumn and winter months, thus affording our migrants and winter-visiting birds a sanctuary in which to feed and shelter safely. Another outstanding high note this year was the Snow Bunting found on the Large Mound in January, a first for the Common since records began in 1974; and yet another first for the Common came in the form of three Whooper Swans at Rushmere in December. There was also a surprising influx of Lesser Spotted Woodpeckers during the spring, a bird that in the previous few years had become an extremely scarce visitor. -
Nesting Biology. Social Patterns and Displays of the Mandarin Duck, a Ix Galericulata
pi)' NESTING BIOLOGY. SOCIAL PATTERNS AND DISPLAYS OF THE MANDARIN DUCK, A_IX GALERICULATA Richard L. Bruggers A Dissertation Submitted to the Graduate School of Bowling Green State University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY December 1974 ' __ U J 591913 W A'W .'X55’ ABSTRACT A study of pinioned, free-ranging Mandarin ducks (Aix galericulata) was conducted from 1971-1974 at a 25-acre estate. The purposes 'were to 1) document breeding biology and behaviors, nesting phenology, and time budgets; 2) describe displays associated with copulatory behavior, pair-formation and maintenance, and social encounters; and 3) determine the female's role in male social display and pair formation. The intensive observations (in excess of 400 h) included several full-day and all-night periods. Display patterns were recorded (partially with movies) arid analyzed. The female's role in social display was examined through a series of male and female introductions into yearling and adult male "display parties." Mandarins formed strong seasonal pair bonds, which re-formed in successive years if both individuals lived. Clutches averaged 9.5 eggs and were begun by yearling females earlier and with less fertility (78%) than adult females (90%). Incubation averaged 28-30 days. Duckling development was rapid and sexual dimorphism evident. 9 Adults and yearlings of both sexes could be separated on the basis of primary feather length; females, on secondary feather pigmentation. Mandarin daily activity patterns consisted of repetitious feeding, preening, and loafing, but the duration and patterns of each activity varied with the social periods.
