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:

Plumage green, grey and yellow. Note bright, yellow base of primaries and sides of tail in all ages and plumages. Deep and heavy conical bill. Tail forked and quite short. Plump build. Female more grey than male, with back diffusely streaked in brown and underparts greyish. Juveniles similar to females, with even more drab colours and heavier streaking (also on underparts). Strongly undulated flight. Often appears somewhat clumsy when trying to perch on feeders etc.

Sound:

Song composed of various sequences of linked sounds, repeated in a vibrating manner; "trrrrrrrrr", "chechechecheche". Sometimes resembles Brambling when making the wheezy "rrrrrrrrr" sound, but differs in being harsher and by "pulling" the pitch downwards (or sometimes upwards) at the end. Contact call a fairly resonant "chep-chep", resembling Redpoll, but less nasal and with a fuller tone. Also a sharp, drawn, ascending "kooeee", (perhaps not obviously recognized as a finch).
