[AS.] A bird like the crow, but smaller, with the base of its beak bare of feathers and quite white, and with a harsh, croaking voice. It feeds on grubs and worms, but will pull up new grass and potatoes, pick turnips, and steal eggs.

Rooks are sociable birds, and build their nests together and live as one family. They usually settle in a clump of high trees, which is called a rookery.
