The grasshopper buzzard (Butastur rufipennis) is a species of bird of prey in the family Accipitridae which is found in a narrow zone of sub-Saharan Africa north of the equator. Taxonomy The grasshopper buzzard forms a superspecies with the white-eyed buzzard (Butastur teesa), rufous-winged buzzard (Butastur liventer), and grey-faced buzzard (Butastur indicus) all of which occur in Asia. Description The adult grasshopper buzzard is grey brown above with a darker head and dark shaft streaks on all of its feathers. The feathers of the mantle and lesser coverts are narrowly with fringed rufous in fresh plumage, although this wears off. The grey tail has faint brown bars.

The secondary feathers are rufous shading to dark brown towards the tip, which is white. The chin and throat are whitish, with three black streaks on either side of throat. The breast is rufous and has narrow shaft streaks of black, the belly and thighs are also rufous but lack markings. The axillary feathers are greyish brown, spotted with white or buff.
