Appearance:

Anonymous, indistinct plumage and secretive behaviour makes it an easily overlooked bird (except when singing). Upperparts brown-grey, tail rufous brown. Underparts dull white. Throat with faint streaking on each side. Very similar in appearance to Nightingale, but tail is not as rufous, and contrasts more with the grayer/brownish back. Overall more drab appearance. Thrush-like behaviour despite the small size, with jumping gait, raised tail and drooping wings.

Sound:

Alarm call alternates between a thin, high pitched, "piuu", and a characteristic dry, rattling, frog-like "rrrrr". Song a highly distinct mix of extremely resonant, full-bodied notes and species specific, dry, rolling, rattling sounds. Can only be confused with Nightingale, but lacks this species' interwoven series of slightly ascending, plaintive 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.
