TWSG News No. 13, December 2001 ABOUT THE GROUP The Threatened Waterfowl Specialist Group (formerly Threatened Waterfowl Research Group) was established in October 1990 and is co-ordinated from The Wildfowl & Wetlands Trust at Slimbridge, UK, as part of the IUCN-SSC/Wetlands International Waterbird Network. The TWSG and its bulletin aim to identify Anatidae taxa that are threatened with extinction, to gather and exchange information on these taxa and to promote their conservation. We also cover other waterbird families not covered by other Specialist Groups (Anhimidae, Heliornithidae, non-marine Laridae). Membership is worldwide and includes 880 organisations, groups and individuals who are active or interested in threatened waterfowl research and conservation. Addresses of TWSG members, further information about the TWSG, this bulletin, and/or membership can be obtained from Baz Hughes at the address TWSG NEWS below.

TWSG News No. 13, December 2001 TWSG News No. 13, December 2001 EDITORIAL THREATENED WATERFOWL SPECIES AND SUBSPECIES Since the last issue of TWSG News 16 months ago, our membership has grown from 735 In the following list of globally threatened and near threatened Anseriformes species and contacts in 115 countries to 880 in 137 countries. This has followed two rounds of strategic subspecies, species categorisations follow the 2000 Red List (BirdLife International 2000) invitations, to known threatened waterfowl conservationists who were not already TWSG whilst sub-species were categorised during the compilation of the IUCN-SSC Anseriformes members, and to all BirdLife International Partners, Partner-Designates and Representatives.

The TWSG would welcome During the same time, membership of the TWSG-Forum list-server has grown from 85 to comment on this list of threatened Anseriformes, especially notification of new data which 290. On the administrative front, we have finally taken the plunge and switched our may lead to re-categorisation of any taxa. databases to Microsoft software, however from the number of computer viruses I now receive (the joys of running a global list server!), we probably won’t be following suit with our e-mail client! SPECIES We continue our efforts to provide information and assistance to threatened waterfowl conservationists worldwide, especially those in global hotspots for threatened waterfowl, such as South America, Eastern Europe, Far-east and South-east Asia. As part of the COMMON NAME LATIN NAME Wetlands International initiative to implement a target driven, objective-led approach to working, we have produced a work plan for the next three years outlining our forward strategy. This includes ongoing support for White-headed Duck, Marbled Teal, Ferruginous Duck, and White-winged Duck, and a major new initiative with BirdLife International to save EXTINCT SINCE A.D. 1600 the Brazilian Merganser. We will be working closely with BirdLife, Wetlands International and New Zealand Swan Cygnus sumnerensis the Ramsar Bureau on a project to identify key sites for threatened waterfowl and to provide Mauritius Sheldgoose Alopochen mauritania Ramsar Contracting Parties with guidance on designating such sites for threatened species. Réunion Island Sheldgoose Mascarenachen kervazoi We will also complete the IUCN Anseriformes Action Plan in 2002 (at last!). Chatham Island Shelduck Pachyanas chathamica Mauritius Duck Anas theodori Sincere thanks to TWSG Assistant Coordinators Andy Green, Murray Williams and Tom Amsterdam Island Duck Anas marecula Rothe who continue to provide much appreciated assistance and support. We also owe a Labrador Duck Camptorhynchus labradorius debt of gratitude to WWT volunteer Graham Lawton who has single-handedly rebuilt the Auckland Islands Merganser Mergus australis TWSG and WWT threatened species web sites (see http://www.wwt.org.uk/threatsp ). Finally, I would like to thank all contributors to this issue of TWSG News, without whom it CRITICALLY ENDANGERED simply would not exist. The participants of the workshop on White-headed Duck Crested Shelduck Tadorna cristata conservation and reintroduction held in Italy in May 2001 kindly allowed us to publish their Campbell Island Teal Anas nesiotis workshop contributions. Nancy Drilling continues her ground-breaking work on White-winged Pink-headed Duck Rhodonessa caryophyllacea Duck in Sumatra and we include important contributions on the status and distribution of Madagascar Pochard Aythya innotata threatened waterfowl from Africa, Eastern Europe, Russia and various CIS countries. Special Brazilian Merganser Mergus octosetaceus thanks to Stephen Garnett who allowed us to publish an extract from his action plan for Australian birds.
