A new report from the Common Wadden Sea Secretariat‘s Joint Monitoring Group of Migratory Birds in the Wadden Sea (JMMB) outlines the latest information on moulting Common Shelduck. The Wadden Sea is of great international importance for moulting Common Shelduck as almost the entire breeding population in western Europe moults there. Traditionally, these Shelduck moulted in the German part of the Wadden Sea, but since the millennium the number moulting there has decreased whilst they have increased in the Dutch part of the Wadden Sea.
This report outlines the results from coordinated aerial surveys undertaken in Germany and the Netherlands in August 2010, 2011 and 2012. Recommendations are made for future trilateral (Germany, Netherlands and Denmark) monitoring of moulting ducks across the Wadden Sea.
The report can be downloaded from the Common Wadden Sea Secretariat website.
