Appearance:

Olive green upperparts, yellowish chest with gradual transition to off-white belly. Very similar to Chiff-chaff, and most field characters are subtle and often hard to see. Distinguished by (usually) pale, yellow-brown legs, dark framing to ear-coverts, stronger supercilium. Long primary projection (often 3/4ths the length of tertials) with irregularly spaced tips (visible when wing folded). Wings slightly more pointed than in Chiff-chaff, and not so fan-shaped. Juveniles often with whole underparts yellow. Frequently flicks tail, but not sideways (unlike Chiff-chaff). Generally also more calm when moving among the foliage.

Sound:

By far most easily identified by it's call or song. Contact/alarm call a soft, plaintive ascending "hoo-eet". Similar to Chiff-chaff, but first part more drawn, giving it a disyllabic feel. Song: A 3-5 second, falling phrase of soft, rippling "svi-svi" sounds, starting high with some attack, and then falling in a mellow manner. The phrase lacks any conclusion, and diminishes both in strength and tempo.

Appearance:

Male shiny black with bright yellow bill and yellow eye-ring. Female dark brown above. Throat and chest in slightly paler tones with diffuse dark spots. Juveniles similar to females, but with fine buff streaking all over. More long-tailed than Redwing and Song Thrush. Flight action with alternating bursts of wing-beats and with little undulation (see Fieldfare).

Sound:

One of the most appreciated song birds. Very melodious and resonant, with long mellow notes and a large register. Less high pitched sounds than Song Thrush, and seldom repeats a phrase. Timbre fuller than both Song Thrush and Mistle Thrush. Well defined pauses between phrases, giving the song a relaxed pace. Large repertoire of calls. Most characteristic is a hysterical rattle often given when flushed. Sometimes preceded by a hard "tok tok", which then accelerates into a panicky arpeggio-like crescendo. Contact call a thin redwing-like "srrreee". Alarm calls: a sharp "tink, tink" or a very high pitch falling whistle.
