How to recognize it

Large black corvid with blue-violet sheen
Adults show a bare whitish patch at the bill base
Walks on the ground, probing soil with the bill
Often seen in flocks; nests colonially in tall trees

The rook is the kind of urban edge presence you notice in noisy groups before you look closely. In adults, the bare pale patch at the base of the bill stands out, but what stays in memory is the busy, communal way it moves and feeds.

Rooks spend a lot of time in flocks, on the ground or coming and going from the treetops where they nest together. Their call is a rough, familiar caw, and in larger gatherings the sound can become quite constant.

They favor open country, pasture, and arable land, along with settlements where tall trees are available. They feed mainly by probing the soil for grubs and other invertebrates, but they also take cereals and other plant food, and in the north some populations move south for winter.
