Appearance:

Small green and yellow finch with contrasting dark wings and tail. Underparts whitish with grey streaking. Secondaries, inner primaries and outer tail feathers with yellow base. Relatively long and pointed bill as opposed to Serin. Male distinct with black crown and bib, bright yellow chest, throat and hind-cheeks. Female less contrasty, with more prominent streaking. Juveniles paler and duller than adults, with even heavier streaking than females.

Sound:

Distinct calls and song. Most often heard is the sharp and disyllabic contact call: "doo-lee", with both notes descending. Sometimes given a in monosyllabic manner "dlyy". The contact call is also prominent in the improvised song. Other typical sounds in the song includes a peculiar wheeze, like someone sucking their teeth, and lots of expert mimicry.

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.
