Appearance:

Plumage like other crossbills; male red, female and juveniles green. Both sexes and all ages with two broad, white wing-bars, which distinguishes it from congeners. Nonetheless, the species is easily overlooked when in mixed flocks with other crossbills. Build slightly more slender and long-tailed than other crossbills. Often discovered through its contact call.

Sound:

Contact call a "chep chep" similar to crossbill but softer, interspersed with characteristic, toy-trumpet call with redpoll-like timbre, but with a more flat intonation. Song more like redpoll than a crossbill, with rattling and chittering notes.

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.
