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:

A medium sized thrush with evenly brown to olive-brown upperparts. Underparts boldly covered with arrow-shaped spots. Chest with buff tones. Faint face patterns and buff underwing coverts distinguishes it from all other thrushes in the region. Lacks the white cheek-spot of Mistle Thrush, and the colour of the back of the head is not paler than the back. Sexes alike. Juveniles with buff-spotted upperparts. Quite short-tailed and compact, with rounded wings. Jerky, and not very undulated, flight pattern.

Sound:

Very melodious, varied and a master imitator. Still easily distinguished by its tendency to repeat introductory motives two or more times, and its many high pitched themes. Each phrase is loud and penetrating and the tempo deliberate. Most heard (but easily overlooked) contact call is a dry and very short "zip", sometimes given as a two syllable call "zip-ip".
