Appearance:

A social, compact, buff bird with full crest, short neck, black bib, black mask and red wax-like extensions to secondaries. Tips of primaries and tail yellow. May be confused with starling when seen in silhouette or when flying, but note fuller head, rounder and more compact body and shorter bill. Flight includes frequent glides, even when changing directions. Not very shy in winter. Hunts insects in flycatcher-like manner in summer.

Sound:

Contact call weak, but distinct and typically alert one to the presence of a flock. A thin, high pitched, ringing "tzrrrrrrr". Song more or less a variation on the contact call.

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.
