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:

A featureless, bulky bunting. Larger than Yellowhammer, but with a shorter tail. Combination of size, build, flight-pattern and sound important for identification. Recalls the bigger larks in build. Takes off with a loose and surging flight, often with legs dangling underneath. Undulations particularly strong just before landing. Wings dark, and tail without white feathers or markings. "Tooth" in upper mandible visible at close range when singing. Bill and legs yellowish pink. Often shows an indistinct, dark breast patch.

Sound:

Song diagnostic. A brittle, jingling and accelerating phrase of about 2 seconds duration. Repeated in a monotonous manner, to form a typical soundscape of fields where it is numerous. Often compared to the sound of a chain of small keys. The phrase starts with a few staccato, ticking sounds that progress into a dry trill, followed by a short ritardando. Calls with a dry "chep" or a brittle "vitt".
