Subspecies
Black Kite (Milvus migrans) and Black-eared Kite (Milvus lineatus) (Sibley and Monroe 1990, 1993) have been lumped following AERC TAC, a treatment supported by review by the BirdLife Taxonomic Working Group of the Milvus phylogeny presented by Johnson et al. (2005) which nests lineatus within the migrans clade. Johnson et al. (2005) show that yellow-billed populations belonging to aegyptius and parasitus do form a separate clade but the authors point out that further studies are needed to help clarify sister relationships within the group. For these reasons it is felt premature to split members of Milvus migrans.
Hybridizes with Red Kite (Milvus milvus) on Cape Verde Is. Several of subspecies frequently awarded separate species status, most notably lineatus and aegyptius (incorporating parasitus). Intergradation indicates probably best regarded as single species, with several well marked subspecies.
The following 7 subspecies are recognised:
migrans (Boddaert, 1783) - North-western Africa and Europe east to central Asia (Tien Shan) and south to Pakistan. Winters south to Africa south of Sahara.
lineatus (Gray, JE, 1831) - Siberia east to Amurland and Japan south to northern India, northern Burma and northern China and Ryukyu Is. Winters south to southern Iraq, southern India and south-eastern Asia. Considered by some authors to be a distinct species, Black-eared Kite (Milvus lineatus).
formosanus Kuroda, Nagamichi, 1920 - Taiwan and Hainan.
govinda Sykes, 1832 - Eastern Pakistan east through India and Sri Lanka to Indochina and Malay Peninsula.
aegyptius (Gmelin, 1788) - Widespread. Considered by some authors to be a distinct species, Yellow-billed Kite (Milvus aegyptius).
parasitus (Daudin, 1800) - Africa south of Sahara, Cape Verde Is, Comoro Is and Madagascar. Considered by some authors to be a subspecies of Yellow-billed Kite (Milvus aegyptius).
affinis Gould, 1838 - Sulawesi and possibly Lesser Sunda Is; eastern New Guinea and New Britain; northern Australia south (in east) to Victoria.
