Slim, long-winged, mid-sized raptor with oddly cuckoo-like markings. Has fairly weak, floppy flight and rarely soars. Generally uncommon species of thick savannah, woodland, and forest edge. Call is a long, mournful whistle. Although its shape is distinctive with practice, cuckoo-hawks can be confused with many other raptor species. Note the widely spaced rufous barring on the belly, and the small crest. Cuckoo-hawks are much slower and weaker fliers than any of the goshawks or sparrowhawks.
