Wallcreeper (Tichodroma muraria)
Alpine Chough (Pyrrhocorax graculus)
Unmistakable. Grey, cliff-climbing bird with long, thin and curved bill. Wings with colourful pattern in carmine red, black and white spots. Habitually flicks wings when foraging (see videolink below), but still hard to spot when not flying. Flight jerky and butterfly-like, and also recalls Hoopoe. Wings appear dark from below, except for white pearls on primaries. Male with blackish throat in breeding season.
Sound:Alarm call a thin trilling "vuiirrrrrrr". Flight call one or several soft whistles, often with (very) short trill as attack or tail. Song variable in length, but main characteristic a sequence of 4-6 long, ascending whistles with timbre recalling whistling kettle. More complex and varied phrases are mixed with the long whistles. Both male and female sings.

CCAll 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.
