Appearance:

Small and short-winged Sylvia with large head and high crown. In all plumages; evenly warm rufous wing-panel (lacking dark centered greater coverts of Whitethroat), very short primary projection, dark tail, thin pointed bill, narrow dark centres to tertials, pure white chin and (incomplete) white eye-ring. Adult male with lead-grey head, dark/black lore and often grey lower throat. Female and immature differs from Whitethroat by short primary projection, smaller size, slender build and thinner bill. Told from immature Subalpine Warbler by warmer rufous wings with only narrow dark centres to tertials.

Sound:

Alarm call a dry, mechanical rattle; "trrrrrrrrrrrt", often rather long, but also given in pulses "trrrrrt-trrrt-trrrrrrrrr". More confluent and softer than similar call of Sardinian Warbler. Song rather weak and squeaky, but may be confused with several congeners. It typically starts with a few fluting notes then quickly giving way to fast alternating between clear tones and rattling pulses of "trrrrt". Phrases are short with marked pauses in between, and the structure is quite fixed even though each phrase is slightly different (in contrast to Sardinian and Subalpine Warbler). Sometimes bursts out in longer, more continuos flight-song.

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.
