For reasons which have been variously assigned, the present species, the _Pyrrhocorax graculus_ of ornithologists, has now become one of the rarest and most local of British birds. Once fairly common, not only in certain inland localities, but on the sea-girt cliffs, many of its colonies have now become deserted. It is a bird of the rock-bound coast, easily recognized by its blue-black plumage and long, curved, red bill. It is not necessary here to indicate the places where colonies still exist. The Chough is a gregarious bird, and many of its habits resemble those of the Jackdaw or the Starling. Its flight is often curiously erratic, the bird, after rising a little way, dropping again with wings closed. Upon the ground it runs quickly, its bright red legs and feet being conspicuous. The note is very like that of the Jackdaw, a chuckling or cackling _chow-chow_; hence the bird’s name of Chough, which, by the way, is often used with the prefix “Cornish,” although the bird is just as scarce in Cornwall as elsewhere now. The food of this bird is chiefly composed of beetles, worms, grubs, and grain. The Chough breeds in colonies, which resort to lofty ocean cliffs, especially such where caves and fissures are plentiful. The nest is very similar to that of the Jackdaw, and varies a good deal in size. Sticks, heather stems, and dry stalks of plants form the outside; the cavity is lined with dry grass, roots, wool, and similar soft material. From four to six eggs are laid in May, creamy-white in ground colour, blotched and spotted with various shades of brown and gray. When disturbed, the Choughs fly out of their nest-holes, and behave generally in a very Jackdaw-like manner. The Chough appears to be a sedentary species in all parts of its distribution. ROCK PIPIT.
