Breeding season starts in late April. Pairs stay together for several years. Usually several pairs are nesting in close proximity on rooftop chimneys, in caves and quarries. The nests are untidy stick structures. They will use long nest boxes. Lays 3-8 (average 4) eggs. | Breeding season starts in late April. Pairs stay together for several years.

Immature Daurian Jackdaws look similar to this species, but more solidly black on the head.
Distribution
Found in most of Europe, patchily in northern Africa, the Middle East and western and central Asia.
Accidental vagrant to northeastern United States and Canada.
Abundant in most of its range; populations decreased in most western European countries in the past but have now mostly recovered.
