During the Middle Ages, the raven was a common visitor to the gallows of central Europe. Since then it has completely disappeared in some places, in others, it is still plentiful, especially in the Alps, the Carpathians and areas north of Berlin. Its distribution embraces the whole of Europe but is irregular. The raven frequents woodland, cliffs, the tundra in the north and in eastern Europe may even be found on buildings. It is a resident bird but after fledging roams far afield.
The nest is often built as early as February by the female from materials which include twigs, moss and hairs, brought by the male. Pairs of birds, remaining together for life, generally use the same nest for years, making only necessary renovations. The 4 to 6 eggs are incubated mostly by the hen, though she is occasionally relieved by the male. The young hatch after 19 to 23 days and remain in the nest 40 to 42 days.
The parent birds bring them food in a special throat sac. The raven is an omnivorous bird but exhibits a preference for meat. It feeds mainly on carrion, but also on smaller animals which it can kill easily with its huge beak. In the vicinity of its nest, it will attack even a large predator fearlessly. In the wild, it is cautious and vigilant, even after the young have fledged, but if reared in captivity from birth it is quickly tamed.
