Appearance:

Male shiny black with bright yellow bill and yellow eye-ring. Female dark brown above. Throat and chest in slightly paler tones with diffuse dark spots. Juveniles similar to females, but with fine buff streaking all over. More long-tailed than Redwing and Song Thrush. Flight action with alternating bursts of wing-beats and with little undulation (see Fieldfare).

Sound:

One of the most appreciated song birds. Very melodious and resonant, with long mellow notes and a large register. Less high pitched sounds than Song Thrush, and seldom repeats a phrase. Timbre fuller than both Song Thrush and Mistle Thrush. Well defined pauses between phrases, giving the song a relaxed pace. Large repertoire of calls. Most characteristic is a hysterical rattle often given when flushed. Sometimes preceded by a hard "tok tok", which then accelerates into a panicky arpeggio-like crescendo. Contact call a thin redwing-like "srrreee". Alarm calls: a sharp "tink, tink" or a very high pitch falling whistle.

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.
