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:

Large, long-tailed eagle. Juveniles unmistakable, with white base of tail, dark terminal band and base of flight-feathers forming a white wing panel. Adult: dark brown with golden tinge to head. Variable amount of white wing panels and base of tail in intermediate plumages. Differs from other eagles by; wings held in shallow V when soaring, narrow wing base, flight feathers paler than coverts and body. Flight pattern elegant with a handful deep beats and typical alternate glides.

Sound:

Not very vocal. A short, clear, yelping "kew". Sometimes in series in mellow tempo. Also mewing, Buzzard-like calls.
