It is a resident breeder in southern China, Myanmar, Thailand, Cambodia, Laos, Vietnam and Indonesia. It is a species of deciduous forest and second growth up to 800 m.
The adult Rufous-winged Buzzards is 38–43 cm long. It has a grey head and underparts, with some streaking on the crown, neck, and breast. The rest of the upper parts are rufous grey, and the upper tail is bright rufous. In flight, from above it shows rufous-chestnut flight feathers and the rufous upper tail, and from below it has a grey body, white underwing coverts, and greyish flight feathers and undertail.
