In adult birds, eyes are bright, sometimes blue, young individuals are dark-eyed. The beak and legs are black.

Galka - a sociable bird, from early spring until late autumn, they fly together with rooks. Together following the tractors during the spring plowing, the birds are looking for earthworms, insects and their larvae in the earth.

In the autumn, after the departure of the rooks, they join the gray ravens, spend the night on trees in yards and in city parks. In the morning they fly out of town to landfills or fields, where they feed. In winter, waste from garbage can play an important role in their nutrition, and sometimes they help to survive.
