Appearance:

Small and compact, green and yellow bird. Smaller than Linnet and Siskin, with heavily streaked flanks, and stubby, deep and grey bill. Rump yellow in adults, but immature birds lack yellow tones in plumage altogether. Wing-bars narrow and much less marked than in Siskin, forehead in males bright yellow. Fairly long-winged with deeply forked tail. Flight light and bouncing. Song-flight of male characteristic, with butterfly-like gliding and slow-motion wing-beats.

Sound:

Song a hectic, jingling, continuous trill, like the pouring of broken glass. The highest notes are constantly modulated to form vague motifs. Timbre comparable to Corn Bunting. Ringing trill also used as contact call, with slightly falling pitch "trrilrlitlitlit". Alarm call a short, redpoll-like "weee-eeet", with an accented high-pitched middle part.

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.
