Presentatie op de Landelijke Dag 2012 van spreker Martin Flade. Samenvatting: Fight for a small brown bird: Current status of the globally threatened Aquatic
Warbler (Acrocephalus paludicola) – Martin Flade (universiteit Brandenburg)
The Aquatic Warbler is the only globally threatened passerine species breeding on mainland Europe,
listed as Vulnerable in the IUCN Red List of Globally Threatened Species due to its rapid decline in the
past and the current limited area of occupancy of <500>95%. Although most current breeding sites are now protected, some peripheral breeding populations
are either decreasing in numbers (Pomerania, Lithuania) or have almost disappeared (West Siberia,
Hungary). However, Aquatic Warblers spend only about 3-4 months at the breeding sites and 2-3
months on migration, but about 5-7 months in the non-breeding areas in sub-Saharan West Africa.
This lecture summarises our current knowledge on breeding sites, population sizes and trends, on
migration routes and wintering sites and the threat status in Europe and West Africa.
