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.

It was held in February at Abu Dhabi (United Arabian Emirates). This kind of meeting gives the opportunity to meet the Chairs of different Specialist Groups and exchange information. Concerning our species, contacts have been established with colleagues from South America, Madagascar and Indonesia where rare or endangered Woodcock and Snipe species are living. Within the framework of this meeting, a booklet was published to present every IUCN Specialist Group. The WSSG should therefore be more visible for a greater number of scientists and conservationists. The WSSG always shows a great dynamism. Our colleagues from Eastern Europe are very active, which is important for the monitoring on the breeding grounds. A new project on Common Snipe has been launched in Russia to provide a better estimation of its conservation status. As a game species, and because wetlands are threatened in many countries, a great attention must be paid to the Common Snipe. One year and a half ago, the 7 th WSSG Workshop was held in Saint-Petersburg. At this time, all the papers that were expected to be published have been received and most of them have been revised by David Gonçalvès, Andrew Hoodless and myself. We are in the final step and the Proceedings should be available in the course of the coming three months. I hope that you will be satisfied with the final result which is one of the centerpieces of the WSSG activity. I wish you a very happy New Year and much success with your scientific work.

High abundance of from the 19 th September to the 25 th October. It woodcocks was recorded during these trips in is the ninth ringing season. This autumn was the end of September and the first pentad of sufficiently warm and rainy. Total rainfall October (Figure 1).

We gather abundance sites were calculated for each year. information about the migration of woodcocks These rates correspond to the % of positive in our country based on long-term roding sites at which at least five roding males were survey data. This short report presents the data observed in each week. They can also be collected in spring 2012 compared to the regarded as a spatial pattern concentrated on results of the first three years of the preferred areas. Results may differ from programme.
