Aquatic Warbler

Acrocephalus paludicola (Vieillot, 1817) AQ AQUWA 12420
Family: Passeriformes > Acrocephalidae

Similar to a Sedge Warbler in general appearance, but with a buff crown stripe and more patterned back, Aquatic Warbler is a rare passage visitor to Britain.

Aquatic Warbler has a restricted breeding range, with 80% of the global population thought to breed in Poland. Autumn movements to the wintering grounds in western Africa result in records of birds along the English Channel coasts. Numbers here fallen in recent years, most likely a result of declines in the breeding populations linked to habitat loss.
