The Alpine chough, or yellow-billed chough, is a crow-family bird with glossy black plumage, a short yellow bill and red legs. It is 37 to 39cm long with a wingspan of 75 to 85cm, slightly smaller than the red-billed chough but with a proportionally longer tail and shorter wings. The juvenile is duller, with a dull yellow bill and brownish legs (Wikipedia, general species account).
It breeds in high mountains from Spain eastwards through southern Europe and North Africa to Central Asia and Nepal, and may nest at a higher altitude than any other bird; its eggs have adaptations to the thin air. It pairs for life and uses a cave or crevice in a cliff, building a lined stick nest with three to five eggs. It feeds in flocks on short grazed grassland and readily approaches tourist sites for food.
