ROOK


Meaning of ROOK in English

(Corvus frugilegus), the most abundant Eurasian bird of the crow family Corvidae (q.v.). It resembles the carrion crow in size (45 cm [18 inches]) and in black coloration, but the adult rook usually has shaggy thigh feathers and has bare white skin at the base of its sharp bill. The species ranges discontinuously from England to Iran and Manchuria and is migratory. Rooks nest in large colonies (rookeries) in tall trees, sometimes within towns. Their nests are solidly constructed of twigs and soil and are used year after year. The birds lay three to five light greenish, heavily speckled eggs, and the young are able to fly about a month after birth. Rooks dig for larvae and worms in meadows and plowed fields and may pull up grain seedlings and young potato plants.
