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:

Medium sized, green woodpecker with black mask. Crown red in all plumages. Females with black moustache stripe, males with red framed in black. Juveniles heavily marked with small black and white spots all over, and less prominent black mask. Bigger and more heavily built than Grey-headed Woodpecker, with longer and stouter bill. Often foraging on the ground. Flight undulated.

Sound:

Song similar to Grey-headed Woodpecker, but not as soft and fluty. Each phrase consist of a series of short "klee", with a laughing quality. Pitch drops slightly throughout the phrase, but not as markedly as in Grey-headed, and tempo is fairly constant (no ritardando). Short "kek" calls when excited and in flight. Drumming of 1.5 seconds duration with decelerating tempo, but not often heard. Another call is similar to Black Woodpecker; a series of resonant "klit-klit-klit-klit-klit-klit", but is less clear, has a more determined start and has less obvious rising pitch at the end of each syllable.
