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:

In all plumages: Brown, unstreaked (or faintly streaked) back, grey bill, only faint wing-bars (or none), distinct white base to primaries and streaked throat. Both sexes with pale eye-ring and pale cheek patch. Breeding male distinct with slate grey head, cinnamon back, red chest and red forehead. Females and juveniles easily confused with Twite or Redpoll but note back and face pattern.

Sound:

Flight-call a quick and "bouncing" "gig-gig" or "tchett-tchett". Most often disyllabic utterances, while Twite seems to vary more the number of syllables. Tone harder and more bouncing. Song a varied, sweet stream of contact calls, mimicry and trills with a staccato feel. Most easily recognized by the frequently interwoven, disyllabic contact calls.
