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:

Very similar to Crossbill, but has thicker neck, bigger head, hardly any forehead and deeper bill. Upper mandible is more curved towards the tip than in Crossbill, and the lower mandible is s-shaped with a "bulge". The tip of the lower mandible is seldom visible from behind the upper. The chest is deeper, and many birds have a front heavy appearance. Adult males shows most distinct characters of the species, and other sexes/ages may be difficult to identify because of overlapping characters with Crossbill. Plumage similar to Crossbill, with dark wings and tail. Males with rufous red head and body, females green. Juveniles greyish green with streaking. Posture less erect than Crossbill, which, together with short tail, contributes to the front heavy impression.

Sound:

Contact call similar to Crossbill's "chepp", but is on average deeper and lacks the "cut-off" ending of each call. In sum: Parrot Crossbill; hard attack, soft ending, Crossbill: softer attack, cut-off ending. The song consist of improvised, resonant twittering and series of contact calls with no apparent phrases. It is generally slower than in Crossbill, with marked pauses.
