Adult Rooks are differentiated from the crow family by the skin color around the bottom of the bill, i.e. a bare gray-white skin. In contrast to a Carrion crow, the feathering around the legs of a Rook appears fuzzy and relaxed. The juvenile Rook appears more similar to a crow as it does not have the bare patch at the bottom of the bill and a fully feathered face.

Juvenile Rooks face fully covered with black facial feathers, and it takes around six months for them to get rid of these facial feathers.

Rooks are known to communicate with other Rooks by making different sounds, usually referred to as call, based on the situations. The Rook bird call is described as 'kaah' or 'caw' and is more similar to a Carrion crow call but less harsh and loud with variable pitch. It usually gives calls both in flight and while in rest. A single Rook gives a call in flight, whereas a Carrion crow gives a call in groups of three or four. The Rook swings its tail and bows while making each caw in a resting position. They make other sounds like a high-pitched squawk, a semi-chirruping call, and a burring sound around the rookery.

Did you know...

Nesting behavior in Rooks is colonial, and they often build nests on remnants of the previous year's nest. A Rook builds a nest on small trees or bushes in hilly areas. Its nest is cup-shaped, composed of sticks, small twigs, and branches that are broken off trees and lined with grass, dead leaves, and roots. Both the adults take part in nest-building, with the males finding the necessary materials while the females arrange them in the nest. They use the nest for breeding. Bill twinning is usually considered as the affiliative behavior shown by the Rooks.

The primary threat to the Rooks is humans. Rookeries were regarded as nuisances in Britain, and they practice holding Rook shoots where humans shot the young birds before they try to fly. These events are considered social, and a source of food as the Rook is a great delicacy.
