The adult has an unstreaked pale brown back and buff underparts, with a warm brown rump. There is a clearer whitish supercilium and the bill is short and pointed. The sexes are identical, as with most warblers, but young birds are richer buff below. Like most warblers, it is insectivorous. The song is fast and similar to Marsh Warbler, with much mimicry and typically acrocephaline whistles added. Its song is weaker and more rhythmic than that of its relative.
It breeds in temperate central Asia. It is migratory, wintering in Pakistan and India. It is a rare vagrant to western Europe.
