The rook (Corvus frugilegus) is similar to the Carrion Crow but is more untidy in its appearance. The plumage is all black with a reddish or purplish gloss but around the base of its beak - nostrils and chin - is bare skin. The untidy appearance is because of the slightly peaked head and the thigh feathers, which look like baggy trousers. The bill is longer and more pointed than that of the Carrion Crow, and the legs are black. A member of the Corvidae family in the passerine order of birds, they feed and roost in flocks in winter, often together with jackdaws. Rooks are resident in Great Britain, Ireland and much of north and central Europe.
