The Black-faced Hawk is a rather small, black and white hawk of northern South America. It is white below and on the head, with black wings, black eye patches, a black tail with a single white band near the base, and orange cere and legs. It closely resembles the White-browed Hawk (Leucopternis kuhli), but has less black streaking on the head and neck and white spots on the back. These two species were long thought to be allopatric, with Black-faced distributed north of the Amazon River and White-browed to the south. Recent evidence indicates that Black-faced also is present south of the Amazon River, in some areas apparently in sympatry with White-browed. Both species occur in the interior and edges of tall lowland forest. Like other Leucopternis hawks, it apparently feeds on reptiles, although very little information is available. The nest and breeding behavior of this species are undescribed.
