About

The crow that we are most familiar with is the carrion crow. It is completely black and makes a hoarse, cawing sound.carrion crows make big nests out of twigs, rags, bones, and anything else they can find, which they hide in tall bushes; they do not nest in colonies like rooks, but are mostly solitary. Carrion crows are birds of farmland and grassland, but are extremely adaptable and will come to gardens for food, often seeming to be quite fearless. They feed on dead animals (as their name suggests), invertebrates and grain, as well as stealing eggs and chicks from other birds' nests. Although now classed as a separate species to the similar hooded crow, the carrion crow can interbreed with its cousin, and hybrids occur where their ranges cross.

How to identify

The carrion crow is all-black, with a glossy sheen. Unlike the Rook, it has a black bill with no bare patches, and does not sport any feathery 'trousers' on its legs. It is smaller than the Raven and has a square-ended tail.

Distribution

Widespread, but absent from the north-west of Scotland, Northern Ireland and the Isle of Man.

Did you know?

A good way to decide if a black crow is a Rook or a carrion crow is to use this simple verse: 'A rook on its own is a crow. A crow in a crowd is a rook.' This is because carrion crows are mainly solitary birds.
