River Warbler

Locustella fluviatilis (Wolf, 1810) VW RIVWA 12370
Family: Passeriformes > Locustellidae

River Warbler, Jon Heath

Records of this rare visitor from eastern Europe peak in September, but the occurrence of several singing males in the summer has led some to speculate it may eventually breed here.

The River Warbler's song often mimics the sounds made by local invertebrates (such as cicadas or bush-crickets), sometimes even mimicking different species during the day and night.
