what is it?
The river warbler ( Locustella fluviatilis ) is an Old World warbler in the grass warbler genus Locustella . It breeds in east and central Europe into western Asia. It is migratory, wintering in east Africa. The genus name Locustella is from Latin and is a diminutive of locusta , "grasshopper". This refers to the song of the common grasshopper warbler and some others in this genus. The specific fluviatilis is Latin for "of a river".
