Closely related to A. rapax and A. heliaca (presumably also A. adalberti), and in the past often considered conspecific with first of those (see A. rapax). Races differ little in plumage, and size variation at least partly clinal; species sometimes treated as monotypic#R. Two subspecies recognized.

Subspecies and Distribution
  • A. n. orientalis Cabanis, 1854 – SE European Russia E to L Balkhash (E Kazakhstan), or perhaps to Tien Shan and Altai; also Inner Anatolia (Turkey)#R; winters in Middle East, Arabia and E & S Africa.
  • A. n. nipalensis Hodgson, 1833 – Altai and Tibet E to NE China; winters mainly in S & SE Asia.
