The Clamorous Reed-warbler (Acrocephalus stentoreus) has a loud and far carrying song - hence its name. Like most warblers, clamorous reed warbler is insectivorous, but will take other small prey items. It breeds from Egypt eastwards through Pakistan, Afghanistan and northernmost India to south China, southeast Asia and south to Australia. There are a number of races differing in plumage shades. The migratory northern race has the richest brown upperparts, and the endemic Sri Lanka subspecies is the darkest form.
