Description Most of the plumage is black or greyish black except for the cheeks, nape and neck, which are light grey to greyish silver. The iris of adults is greyish white or silvery white, the only member of the genus outside of the Australasian region to have this feature. The iris of juvenile jackdaws is light blue. The bird is sociable, moving around in pairs (male and female) or in larger groups, though the pairs of birds stay together within the flocks. Kai...

Distribution and habitat Jackdaws are found over a large area stretching from North West Africa through virtually all of Europe, Iran, north-west India and Siberia, where they inhabit wooded steppes, woodland, cultivated land, pasture, coastal cliffs and villages and towns.

Behaviour
Diet The jackdaw mostly takes food from the ground but does take some food in trees. It eats insects and other invertebrates, weed seeds and grain, scraps of human food in towns, stranded fish on the shore, and will more readily take food from bird tables than other Corvus species.

Nesting Jackdaws usually nest in colonies in cavities of trees, cliffs or ruined and sometimes inhabited buildings, usually in chimneys, and even in dense conifers. Eggs, normally 4-5, are incubated for 17-18 days and fledge after 30-35 days. In most birds and reptiles, an egg (Latin ovum) is the zygote, resulting from fertilization of the ovum. ...

Social behaviour Konrad Lorenz studied the complex social interactions that occur in groups of jackdaws and published his detailed observations of their social behaviour in his book King Solomon's Ring. To study jackdaws, Lorenz put coloured rings on the legs of the jackdaws that lived around his house in Altenberg, Austria for identification, and he caged them in the winter because of their annual migration away from Austria. His book describes his observations on jackdaws' hierarchical group structure, in which the higher-ranking birds are dominant over lower ranked birds. The book also records his observations on jackdaws' strong male–female bonding; he noted that each bird of a pair both have about the same rank in the hierarchy, and that a low-ranked female jackdaw rocketed up the jackdaw social ladder when she became the mate of a high-ranking male. Lorenz being followed by his imprinted geese Konrad Zacharias Lorenz (November 7, 1903 in Vienna – February 27, 1989 in Vienna) was an Austrian zoologist, animal psychologist, and ornithologist. ...

Jackdaws have been observed sharing food and objects. The active giving of food is rare in primates, and in birds is found mainly in the context of parental care and courtship. Jackdaws show much higher levels of active giving than documented for chimpanzees. The function of this behaviour is not fully understood, although it has been found to be compatible with hypotheses of mutualism, reciprocity and harassment avoidance.[2] Type species Simia troglodytes Blumenbach, 1775 distribution of Species Pan troglodytes Pan paniscus Chimpanzee, often shortened to chimp, is the common name for the two extant species in the genus Pan. ...
Jackdaws in culture and custom In some cultures, a jackdaw on the roof is said to predict a new arrival; alternatively, a jackdaw settling on the roof of a house is an omen of death and coming across one is considered a bad omen.[3]
