The western jackdaw, also known as the Eurasian or European jackdaw, is a black-plumaged crow-family bird 34–39cm long. Four subspecies are recognised, differing mainly in how dark or pale the grey on the head and nape is. It is found from north-west Africa through all of Europe, except the subarctic north, and eastwards through central Asia to the eastern Himalayas and Lake Baikal (Wikipedia, general species account).
It is mostly resident, though northern and eastern populations migrate south in winter. It is gregarious and vocal, living in small groups. About five pale blue or mint-green eggs with brown to grey speckles are laid and incubated by the female. The source does not describe its status in China (Wikipedia, general species account).
