From Wikipedia, the free encyclopedia
A chough is any of two species of passerine birds that constitute the genus Pyrrhocorax of the Corvidae (crow) family. These are the red-billed chough (Pyrrhocorax pyrrhocorax) and the Alpine chough (or yellow-billed chough) (Pyrrhocorax graculus). The choughs have black plumage and brightly coloured legs, feet and bills and are resident in the mountains and rocky sea-cliffs of southern Eurasia and North Africa. They have long broad wings and perform spectacular aerobatics. Both species pair for life and display fidelity to their breeding sites, which are usually caves or crevices in a cliff face. They build a lined stick nest and lay three to five eggs. They feed, usually in flocks, on short grazed grassland, taking mainly invertebrate prey, supplemented by vegetable material or food from human habitation, especially in winter.
