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.

Appearance:

Like a pale, giant Tawny Owl. Yellow bill, long, evenly barred, tail. Eyes dark. Facial disks pale, unmarked and almost fused, lacking the dividing wedge of Tawny Owl. In flight, note lack of pale base of primaries and much slower wing-beats than Tawny. Mild facial expression, but very aggressive at breeding ground.

Sound:

Song: 6 -10 evenly spaced "ho"'s, starting silently and gradually rising in volume and pitch. Also an accented "ho-ho, ho-ho-it, ho-ho", three middle notes ascending and the two notes before and after descending. A variety of barking social sounds.
