Although common on the neighbouring shores of the Continent, this species has occurred here very seldom. It is abundant throughout Europe in summer as far north as the southern shores of the Baltic, and nests commonly in France, Holland, and Belgium. It inhabits reed-beds or thick cover near the margins of streams, ditches, and ponds. It does not skulk like the Reed Warbler, but, on the contrary, is always sitting on the top of the tallest reeds and flying about from one clump to another.

The upper parts are warm olive brown, with light margins to the wing and tail feathers. There is a dull whitish streak from the bill over each eye. The under parts are buff; chin and belly whitish. Length 7·8 in.; wing 3·75 in.

It has been taken only in the South and East of England.
