Aquatic warblers in Salreu



Aquatic warblers Acrocephalus paludicola are the rarest and the only internationally threatened passerine in mainland Europe. Apart from a very small remnant population in Western Siberia, its breeding grounds are completely confined to Europe. Drainage has meant that this species has declined. Its stronghold is now the south of Belarus, where 70% of the world's population breeds. This time of the year Aquatic warblers show up also in the wetlands of Salreu. These birds are on their way to Africa, where they spend the winter. They use the food rich marshes of Salreu to build up strength for the next part of their journey. JMN and I managed to ring two of these birds on September 4.




Typical Aquatic warbler habitat in Salreu: sedges and rice fields.
