Appearance:

Small and restless species easily confused with Sedge Warbler, Acrocephalus schoenobaenus, but showing both plumage and structural differences. Plumage differs from A. schoenobaenus in; broad, white supercilium ending without narrowing, dark crown (usually appears black), pure white throat, grey ear-coverts, dark legs and warm-rufous flanks, rump and neck. Facial markings recalling firecrest. Very short primary projection and longer, more evenly rounded tail recalling Wren when raised. Bill thinner than A. schoenobaenus. Skulky behaviour, forages low in vegetation, on ground or near water surface. Some variation in both size and plumage between western and eastern subspecies.

Sound:

Contact call a dry "trrrt", similar to corresponding call of Sedge Warbler. Song most resembling that of Reed Warbler (A, scirpaceus), but often includes diagnostic (unique among congeners), pure-sounding note sequence resembling crescendo of Common Nightingale (L. megarhynchos), before launching into typical Acrocephalus sounding song. This latter type can be sustained for some time without the diagnostic sequence and is more difficult to distinguish from A. scirpaceus. Note faster tempo and more variation.

Appearance:

Small, short winged warbler. Similar to Scrub Warbler (Scotocerca inquieta) and Graceful Warbler (Prinia gracilis), but both wings and tail much shorter. Tail fan-shaped with black and white tips. Heavily streaked back, buff underparts and pale throat and vent. Pale area around eye. Flight diagnostic, with whirring wings and short, slightly spread, fan-like tail. Song flight even more distinct, with long undulations synchronised with voice.

Sound:

Male song a diagnostic, monosyllabic, high-pitched "cist", repeated in an even rhythm about once every second, while in bounding song-flight or perched. Alarm call a short, clipping "witt", repeated in series.
