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:

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".
