The Western Jackdaw is a passerine bird in the crow family. The name derives from the word "jack", meaning "small", and "daw", its native English name. Found across Europe, western Asia and North Africa, it is mostly resident, although northern and eastern populations migrate south in winter. Four subspecies are recognised, which mainly differ in the colouration of the plumage on the head and nape. Linnaeus first described it formally. Later analysis of its DNA shows that, with its closest relative the Daurian Jackdaw, it is an early offshoot from the genus Corvus, and possibly distinct enough to warrant reclassification in a separate genus, Coloeus. Measuring 34 – in length, the Western Jackdaw has black plumage with a grey nape and distinctive pale-grey irises. It is gregarious and vocal, living in small groups with a complex social structure in farmland, open woodland, on coastal cliffs, and in urban settings. An omnivorous and opportunistic feeder, it eats a wide variety of plant material and invertebrates, as well as food waste from urban areas. Western Jackdaws are monogamous and build simple nests of sticks in cavities in trees, cliffs, or buildings.
