Warm brown above and pale below; strong dark eyestripe contrasts with white eyebrow. Smallish reed warbler with long and strongly rounded tail, short bill with dark tip, and short primary projection. Difficult to separate visually from other small Acrocephalus warblers, especially Blunt-winged Warbler; note Paddyfield’s more prominent pale eyebrow which strengthens behind the eye, as well as longer-winged appearance. Also compare with Iduna warblers. Breeds in extensive reed beds; in nonbreeding season found in marshes, but also more scrubby areas. Distinctive, melodious song.
