Appearance:

Adult male unmistakable if seen well. Body and head bright yellow, lores, wings and tail black. Females and young males less distinct, with lime-green back, pale, streaked underparts and black wings and tail. Bill quite strong with reddish colour in adults, and grey in young birds. Despite the bright plumage the bird is difficult to see due to skulking behaviour in foliage. Usually spotted when moving from tree to tree in undulating flight. Then resembles a large thrush or woodpecker, quickly darting upwards into the next tree-top.

Sound:

Varied repertoire, but song and common contact call very distinct. Song a series of 1-2 seconds long phrases of 3-5 yodeling, clear, fluting notes, interspersed with 2-3 second pauses. Tone very full-bodied, melodic and pleasing. Contact call surprisingly different: A forced, drawn "weeackt", slightly resembling Jay, but less harsh, and much more nasal. Other sounds include a Wryneck-like warning call.

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.
