Legge's hawk-eagle (Nisaetus kelaarti) is a bird of prey. Like all eagles, it is in the family Accipitridae. It breeds in the Indian subcontinent, from southern India to Sri Lanka. Its specific name kelaarti honors the physician-zoologist E.F. Kelaart. The English common name honours William Vincent Legge, who described the species in 1878. Legge's hawk-eagle is a medium-sized eagle and fairly large-sized raptor. The typical adult has brown upperparts and pale underparts, with barring on the undersides of the flight feathers and tail. The breast and belly are heavily streaked. The wings are broad with a curved trailing edge, and are held in a shallow V in flight. Sexes are similar, but young birds are often whiter-headed. Legge's hawk-eagle was formerly considered to be a subspecies of the mountain hawk-eagle, but it is smaller and has unstreaked buff underwing coverts. A 2008 study based on the geographic isolation and differences in call suggested that this be treated as a full species, Nisaetus kelaarti.
