Appearance:

Small thrush with rufous flanks, strong white supercilium and whitish moustache stripe. Upperparts evenly brown, underparts white with dark spots on chest and sides. Underwing coverts rufous. Fairly compact build, with slightly more pointed wings and shorter tail than Song Thrush. Juveniles less brightly coloured, with buff spots on upperparts. Behaviour less secretive than Song Thrush.

Sound:

Song delivered in two parts. First a simple, melodic phrase of 3 - 6 notes, usually followed by a more silent, indistinct, fast and less melodic, chattering sequence. First part highly variable from place to place, but constant in individuals. Often causes confusion when a new dialect is heard at a distance, since only the first part is far-reaching, and the diagnostic two-part structure gets lost. Contact call a thin, drawn and sharp "sreee". Often heard at night during migration. Alarm call harder, dryer and more raucous than other thrushes.

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.
