Distribution: Indomalayan. MYANMAR and south-central CHINA south to Indochina and northern Malay Peninsula, JAVA, and SULAWESI. more....

Subspecies: Monotypic.

Taxonomy: Forms a superspecies with B. rufipennis, B. teesa, and B. indicus. Amadon (1982) included Butastur in the sub-buteos, but later removed it from that group (Amadon and Bull 1988) and emphasized its similarity of Kaupifalco. Griffiths (1994) also thought that Butastur and Kaupifalco are sister taxa, based on her study of syringeal morphology. The results of Lerner et al. (2008) from analyses of mitochondrial and DNA genes showed that Butastur forms a monophyletic group that is a buteonine genus and not related to Kaupifalco.

Movements: Probably non-migratory.

Habitat and Habits: Inhabits open, lightly wooded cultivation and forest edge, and occasionally urban areas. Often soars very high. Occurs singly and in pairs (Coates and Bishop 1997).

Food and Feeding Behavior: Feeds on small mammals, reptiles, and frogs. Hunts from tree perches in or nearopen areas (Coates and Bishop 1997).

Conservation: Categorized globally as a species of "Least Concern" by BirdLife International.
