The rook
The seed-eating crow is a social bird that lives in large colonies. These birds are omnivorous and feed on a variety of foods including insects, seeds, fruit and food scraps. During the nesting season, black-crowned nightingales build bulky nests out of twigs, which they place in tall trees, usually in colonies. Some populations are migratory while others are sedentary.
