The Carrion Crow (Corvus corone) is a British bird of the family Corvidae, order Passeriformes, closely related to Corvus cornix, the hooded crow. The carrion-crow, or simply the crow, is about 45 cm inches in length, and about 92 cm between the tips of the wings. Its plumage is compact and glossy blue-black with some greenish reflections. Its favourite food is carrion of all kinds; but it also preys upon small quadrupeds, young birds, frogs, lizards, etc, and is a confirmed robber of the nests of game birds and poultry. It is not gregarious, being generally met with either solitary or in pairs. It builds a large isolated nest, with from four to six eggs, generally of a bluish-green with blotches of brown. The carrion-crow is easily tamed, and may be taught to articulate words.
