These birds belong to the Corvidae family. You can spot them by a patch of white, bare skin on their faces. This patch sits near the eyes and the base of the bill. It can make the bird's head look more domed than it really is. Rooks are very gregarious, which means they love to live in large groups. They often build their nests together in the tops of tall trees.

These groups of nests are called rookeries.

Finding food is a busy job for a rook. They mostly forage on the ground in open fields or pastures. They use their strong, grey-black bills to probe the soil. This helps them find grubs, worms, and other small creatures living in the dirt. About 60 percent of what they eat is plant matter. This includes things like cereals, seeds, fruit, and acorns. They also eat insects, snails, and even small mammals.

In towns, they might even find food scraps in rubbish bins.

Humans have studied these birds for a very long time. A Swedish naturalist named Carl Linnaeus gave them their scientific name in 1758. He wrote this in his famous book, Systema Naturae. The name Corvus means "raven" in Latin. The second part, frugilegus, means "fruit-gathering." This comes from words meaning "fruit" and "to pick." The common name "rook" likely comes from the bird's harsh, loud call.

This call sounds like a "caw" or "kaah."

Different types of rooks live in different places. The western rook lives from Europe to China. The eastern rook lives in parts of Asia, like Mongolia. In New Zealand, some rooks were introduced between 1862 and 1874. Now, they are seen as an invasive species there. In the wild, rooks often live in the Palearctic region. This area stretches from Scandinavia all the way to eastern Siberia. They usually stay in lowland areas near farms and villages.

Rooks are famous for being very intelligent. They can solve problems to get a reward. In tests, some rooks learned to use tools to get food. They even learned to push stones into tubes to move food toward them. They can also use sticks or bend wire to reach things.

This smartness is shared with other birds in their family. Like many birds, they also form strong bonds. A male and female rook often stay together for their whole lives. They work as a team to build nests and care for their chicks.
