sub the raven-birds probably has Dohlen this at the most strongly established group-behavior. they like to live together in larger troops with solid-joined ranking and brood in colonies normally. Konrad Lorenz explored the social-behavior in detail at "tame" free-flying Dohlen and portrayed very descriptively.

Shape Dohlen live in the restrained areas of Eurasia, with what individual populations differ in the plumage-color. The eastern race ("Halsbanddohle") has a whitish neck and neck, while the birds in the German area mainly black and only at the neck easily gray is colored. Dohlen differ in its more inferior size (until heavily 250 g and 33 cm long), the daintier beak and its more agile movements from the rooks, with whom they often are socialized in large flocks in the winter.

Food The food of the Dohlen is very versatile, they look for insects, worms and other small animals, but they like to assume also vegetable food.

Reproduction As cave-breeders, Dohlen build its nests in tree-caves, rock-holes and wall-niches, with what they often here-manage gigantic quantities of branches in order to create a base for the nest built and carefully padded out of brushwood. Frequently, Dohlen brood near human settlements so that they hand over a familiar picture around around the towers of rural places. In approximately 18 days of erbrütet mainly the female 3-7 young, of which care is taken by both alto-birds, until they leave the nest after 28-32 days. The squabs then are fully airworthy in the age of 36 days while they still are almost bare in the birth and entgegensperren a big blood-red pharynx with shining-yellow Randwülsten the parents.
