Rooks (Corvus frugilegus) are small passerine birds widely distributed in north and central Europe and some parts of Asia. They prefer farmlands and wooded steppes.
They sport a distinctive all-black plumage with a gray-white face. They have black legs and feet, feathered, rounded nostrils, and strong, thin beaks.
Adults can reach 45 to 47 cm in size and weighs from about 337 – 531 grams. Rooks feed mainly on earthworms, insect larvae, other small mammals, fruits, and cereal grains.
