Jackdaws are pigeon-sized members of the crow family, mainly dull black in colouring. They have paler grey colouring on their heads and necks below and behind their eyes, but the extent of this paler colouring varies between individuals, and some birds have a pale wreath-like ring around their necks. They have shortish black beaks and black legs. Their irises are greyish white (adults) or grey-blue (juveniles).

Jackdaws are very sociable, and their flocks have well-defined hierarchies. Pairs tend to stay close together within larger flocks.
