Large, raucous forest raptor. Unmistakable by virtue of its size, social habits, and loud, incessant calls. At a distance, note slow flight and contrasting white belly. Found in regions of continuous lowland forest; does not occur in extensively disturbed areas. Mostly observed in the canopy and mid-story where it knocks down wasp and bee nests to the ground to feed on the larvae; also consumes fruit. Groups will approach and mob humans passing through their territory.
