Appearance:

Olive green upperparts, yellowish chest with gradual transition to off-white belly. Very similar to Willow Warbler, and most field characters are subtle and often hard to see. Distinguished by (usually) black, or dark-brown legs, only faint dark framing to ear-coverts, less marked supercilium. Shorter primary projection (1/2 to 2/3'rds the lenght of tertials), with regularly spaced tips (visible when wing folded). Wings more fan-shaped and less pointed than in Willow Warbler. Juveniles much less yellow below than in W.Warbler. Generally leaves a duller and greyer impression than W. Warbler, but plumage very variable. Frequently flicks tail, even sideways. Generally also more active when moving among the foliage.

Sound:

Contact/alarm call a soft, plaintive ascending "hooeet". Similar to W.Warbler, but shorter with a monosyllabic feel. Song a very distinct: "chiff-chaff-chiff-chiff-chaff-chiff", in a regular clock-like rhythm. Each syllable at seemingly random pitch, but no large intervals tonally. Sometimes "get stuck" at one note.

Appearance:

Anonymous, indistinct plumage and secretive behaviour makes it an easily overlooked bird (except when singing). Upperparts brown-grey, tail rufous brown. Underparts dull white. Throat with faint streaking on each side. Very similar in appearance to Nightingale, but tail is not as rufous, and contrasts more with the grayer/brownish back. Overall more drab appearance. Thrush-like behaviour despite the small size, with jumping gait, raised tail and drooping wings.

Sound:

Alarm call alternates between a thin, high pitched, "piuu", and a characteristic dry, rattling, frog-like "rrrrr". Song a highly distinct mix of extremely resonant, full-bodied notes and species specific, dry, rolling, rattling sounds. Can only be confused with Nightingale, but lacks this species' interwoven series of slightly ascending, plaintive notes.
