Appearance:

Differs from Barn Swallow in all plumages by pale throat and black under tail coverts, which are visible at greater distance than the red rump. Rufous cheeks and collar. Underparts finely streaked, giving the bird a slightly "dirty" look from a distance, with less contrast to the upperparts than in Barn Swallow. Immature birds with short streamers and buff cheeks and rump. Build more compact than Barn Swallow, with shorter bill, rounded wings and slightly shorter streamers. Flight slower and with more frequent gliding.

Sound:

Less vocal than Barn Swallow. Song slower, and less energetic. Each phrase starts with a few staccato notes, leading to a short, twittering sequence of a few seconds length, with some drawn notes. Timbre is metallic and "broken", and quite diagnostic.

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.
