The raven occurs nearly in the entire northern hemisphere. In the western palaearctis it breeds in the whole of the scandinavian area, in eastern Europe to the Ural, in the south in Turkey, Greece, southern Italy, the mediterranean isles, in Spain and Portugal. Furthermore it also breeds in Morocco, Algeria and Tunesia. The raven is a resident bird, i.e. it is not migratory but stays in the breeding area for the whole year. This applies at least to adult animals which often stay as a pair for many years.
Young animals leave their parents breeding territory and travel some hundred kilometres.
After three years they become sexually mature and establish breeding territories of their own. They build nests on trees and on rocks but can also use abondened nests of birds of prey. Nests can be used for a number of years. May. Ravens are omnivorus. They prey on small mammals but also on insects, young birds, amphibians and others.
