Along with C. monedula sometimes separated in Coloeus, but recent studies#R#R found them to form a basal clade within present genus. The two are sometimes considered conspecific, but they seem to replace each other geographically in vicinity of L Baikal and N Mongolia, meeting on very narrow front, but with very few reports of mixed pairings. Dark immature of present species at one time thought to be a different species (“C. neglectus”). Confusing variety of intermediate specimens were also given names (e.g. griseiventris and nigriventris). Other synonyms are fuscicollis (Baikal) and khamensis (Xinjiang, in W China). Monotypic.

Distribution:

S part of E Siberia from NW L Baikal E to Amurland and Ussuriland (SE Russia), S through Mongolia to E & NE China (E from NE Xinjiang and E Qinghai, S to SE Xizang, Yunnan and Jiangsu) and N Korea. N breeders migrate S to as far as SE China, S Korea and S Japan.
