L 41-49cm, WS 81-94cm.\n\nBreeds in colonies (rookeries) in agricultural areas. Builds loose stick nests close together in crowns of tree clumps near farms, parks, highway sides and in villages; in spring, before trees in leaf, nests like large witches brooms.\nForages in flocks on ploughed fields, on pasture and along ditch sides, often accompanied by Jackdaws.\nRelative bold where not persecuted. Omnivore, but takes mostly insects and earthworms.\nMigratory in far NE.\n\nThis Crow is relative scarce in the Netherlands, except the North and South, where the Habitats are still intact.
Sitting on a birch branch, Rook watches the actions of the photographer. A very smart bird.

The rook (Corvus frugilegus) is a member of the family Corvidae in the passerine order of birds.  This species is similar in size to or slightly smaller than the carrion crow, with black feathers often showing a blue or bluish-purple sheen in bright sunlight. The feathers on the head, neck and shoulders are particularly dense and silky. The legs and feet are generally black and the bill grey-black. Rooks are distinguished from similar members of the crow family by the bare grey-white skin around the base of the adult's bill in front of the eyes. The feathering around the legs also looks shaggier and laxer than the congeneric carrion crow.
