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:

Fairly large warbler with long tail, giving the whole bird an elongated look. Tertials, secondaries and coverts with rufous fringes in contrast to greyish brown back. Underparts pale with buff flanks. Outer tail feathers white. Steep forehead and white throat. Males with slate grey head.

Sound:

Variable. Usually recognized by fairly concise phrase, usually with three ascending and descending parts. Often ends with more indistinct mimicry, or subsong. May omit characteristic phrase and sing more cryptic for periods of time, and may be more difficult to identify. Warning call a harsh, drawn "weeet", usually with accented ending, sometimes rising abruptly in pitch.
