(Peters 1931, 1, 200); "Medium-sized kite, with variably large and conspicuously hooked bill, heavy but rounded pigeon-like head, longish wings and tail, and short legs with weak feet. Perches in trees, usually skulking within canopy, but unobtrusive and sluggish rather than shy  ... Wide range of plumages apparently mimics various faster or stronger raptors that are otherwise different in shape or behaviour" (Ferguson-Lees & Christie 2001).
