Appearance:

A large and long-tailed thrush. Slate grey lower back, rump and head. Brown upper back and yellow buff breast with dark spots. The all dark tail contrasts with the grey rump. Tail colour combined with white underwing distinguishes it from all other thrushes when flying. Flight undulated in long waves, with alternating glides and bursts of wing-beats.

Sound:

Very vocal. Scolding call a hard "check", often given in decelerating series. Contact call in migration a soft, pleasant but, buzzy "weet". Song a mix of dry contact calls; "trrrt trrrrt", and high pitched, drawn out, chattering improvisations. Typically bursts into continuos, squeaky chattering at takeoff.

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.
