Appearance:

Small, short winged warbler. Similar to Scrub Warbler (Scotocerca inquieta) and Graceful Warbler (Prinia gracilis), but both wings and tail much shorter. Tail fan-shaped with black and white tips. Heavily streaked back, buff underparts and pale throat and vent. Pale area around eye. Flight diagnostic, with whirring wings and short, slightly spread, fan-like tail. Song flight even more distinct, with long undulations synchronised with voice.

Sound:

Male song a diagnostic, monosyllabic, high-pitched "cist", repeated in an even rhythm about once every second, while in bounding song-flight or perched. Alarm call a short, clipping "witt", repeated in series.

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.
