About 33 centimetres long, the jackdaw is a dark and compact bird with a strong bill, grey nape and whitish eyes.
The jackdaw is basically resident, although northern populations migrate south in winter. It breeds both in the immediate vicinity of human settlements and in natural parks and deciduous woods, as well as in mountainous areas and on coastal cliffs.
A highly intelligent and social bird, the jackdaw breeds in colonies and forages in flocks. It nests in chimneys, air shafts, tree holes, caves and rock crevices and is omnivorous.
