Western Jackdaw

The Western Jackdaw is a compact crow measuring 34–39 centimetres. Its mostly black plumage contrasts with a grey nape and a conspicuously pale iris. Four recognised subspecies differ chiefly in how dark or pale the head and nape appear. The bird is highly vocal and social, and its smaller proportions separate it from many other familiar crows. Northern and eastern populations migrate south for winter, while much of the population elsewhere remains resident. (Wikipedia, Western Jackdaw account)

Western Jackdaws occupy farmland, open woodland, coastal cliffs, and towns. They feed opportunistically on plant material, invertebrates, and discarded human food. Birds live in groups with a complex social structure, but breeding pairs are monogamous. A pair builds a simple stick nest inside a cavity in a tree, cliff, or building. The female incubates a clutch of roughly five pale blue or mint-green eggs marked with brown or grey, and the young leave the nest after four to five weeks. (Wikipedia, Western Jackdaw account)
