The White-eyed Buzzard (Butastur teesa) is a medium sized hawk, unrelated to the true buzzards of the genus Buteo, found in South Asia. Adults are characteristic, having a rufous tail, a distinctive white iris and a white throat with a contrasting mesial stripe and bordered by dark moustachial stripes. The head is brown and the median coverts of the upper wing are pale. They do not have typical carpal patches found on the underside of the wings of true buzzards but the wing lining appears dark in contrast with the flight feathers. They often sit upright on perches for prolonged periods and will soar on thermals in search of insect and small vertebrate prey. They are vociferous in the breeding season and several birds may be heard calling as they soar together.
