Appearance:

Small member of the thrush family, with erect posture and large head. Distinct white or buff supercilium in all plumages. Base of primaries shiny white in adults, especially adult male. Coarsely spotted buff rump. Base of tail with white triangular patches. Juveniles with white speckles on upperparts and whitish throat. Lacks the white base of primaries, but supercilium bold.

Sound:

Contact call resembles many of it relatives. A short, soft "peeu", followed by a hard "check" (like hitting two rocks together). The "peeu"-sound is depper and more resonant than similar sounds by Wheatear and Stonechat. Song variable with lots of mimicry. The short phrases starts with dry, rattling or sneering trills, followed by clear whistling notes and expert mimicry. More varied, both in tone and tempo, than both Stonechat and Wheatear.

Appearance:

All black plumage, red legs and relatively short and straight, yellow bill. Note that immature Red-billed Chough has yellowish-brown bill, but never as pure yellow as in Alpine Chough, and the whole bill is curved. Easily confused with Red-billed Chough at a distance where both species occur, but note more narrow, less fingered wings, and longer, more rounded tail. Resembles Jackdaw in size, but flying Alpine Choughs differs by two-toned underparts of wings (darker coverts). Flight acrobatic, but a little more stilted than Red-billed Chough.

Sound:

Diagnostic and very different from Red-billed Chough. A sharp, quite high-pitched, whistling trill "chreeeee". Usually alternated with pure-toned high-pitched whistles, falling abruptly in pitch with a "clipping" ending.
