The western jackdaw, also called the Eurasian or European jackdaw, is a black crow-family bird 34–39 cm long with a grey nape and a distinctive pale iris; immatures have duller, less demarcated plumage and four subspecies differ in the paleness of the head and nape. It is found from north-west Africa through Europe, except the subarctic north, and east through central Asia to the eastern Himalaya and Lake Baikal, including Afghanistan, Pakistan and north-western India (Wikipedia, general species account).
It is mostly resident, although northern and eastern populations migrate south in winter. It is gregarious and vocal, living in small groups with a complex social structure. Pairs are monogamous and build simple stick nests in cavities. About five eggs are laid and incubated by the female, and the young fledge in four to five weeks. It is not in SoIB 2023 as a separate category (Wikipedia, general species account).
