Genus
Members of the genus Buteo are broad-winged, broad-tailed hawks, Well adapted for soaring. The bill, legs and talons are of average proportions. There is much colour variation both within the species, and, by way of phases, within individual species. In all cases the young are quite different from adults in that they are all well camouflaged with an overall brown appearance with varying amounts of striping below and paler mottling above.
The 25 species are spread worldwide with the exception of Australasia and much of the Indian sub-continent.
Physical charateristics
The pale morph resembles the Red-tailed in having a rufous tail, brown upperparts, and pale underparts, but is more uniformly streaked below. The dark morph is black overall, with a grayish tail banded narrowly in black.
