The subjects of WSSG are species of the genera Scolopax , Gallinago and Lymnocryptes that in several respects differ remarkably from all other wader species. For this reason a separate research unit was established.

This is the final point of this workshop which allows everybody to remember important information on our work in the Woodcock 3 Snipe world. A very exciting news published in 2013 is the rediscovery of Moluccan Woodcock Scolopax rochussenii during a French ornithological survey of the Obi archipelago in 2010. This species has not been observed since the beginning of 1980s and is classified as HEndangeredI by IU N and 1ird4ife International. ,uring the expedition, its vocaliJation was registered for the first time and knowledge about its habitats was improved. In addition to usual papers published in the WSSG Newsletters, you will find in this issue two new articles which show the dynamism of biologists involved in Woodcock 3 Snipe research. First, Spanish colleagues have launched a study of migration of ommon Snipe and Jack Snipe using geolocators (G4S). Thirty birds were equipped in 2013 and results are expected in the coming months. Secondly, .ussian colleagues have explored the Woodcock roding behaviour in Sakhalin Island. To my knowledge, it is the first time we get this kind of data at the eastern side of the breeding range, close to the Pacific coast, and their contribution is precious. In the western part of Europe, the major research topic remains the migration of Woodcock thanks to satellite tracking. After a pioneer period instigated by Spanish colleagues, the biologists of the Game onservancy Trust in GreatA1ritain are now the leaders with near 30 tagged birds. One of the main results so far is a higher proportion of Siberian birds than expected among woodcocks wintering in Western Europe. Technological improvements should encourage other countries to participate in this very exciting research field, using also GPS. Finally, I remind you that the whole WSSG NewslettersLcollection is now available on the Wetlands International website at the page of our Specialist Group. It is a great opportunity to have a look on our work carried out during near 40 years. I wish you a very happy New 0ear and much success with your scientific work. 5ves Ferrand Coordinator Office national de la chasse et de la faune sauvage .esearch ,epartment M Migratory 1irds Unit 39, 1d Albert Einstein S 423NN, 44323 Nantes edex A France Telephone O P33 2 N1 2N 07 88; Fax O P33 2 40 48 14 01 E-mail O yves.ferrandRoncfs.gouv.fr The Moluccan Woodcock Scolopax rochussenii , a species recently rediscovered (from La Bécasse des bois Histoire naturelle , Effet de lisière Editeur ; © .
