Large, mostly black bird found in the canopy of lowland forests. Male has wine-colored throat that can be puffed out expressively, but is often difficult to see in poor light. The overall dark color, stout silvery bill, and chunky proportions help identify this bird even at a distance. Also listen for the distinctive purring whistles, “prr-woop, prr-woop.” Typically found in small vocal groups that parade through the canopy, sometimes following mixed-species flocks. Compare with umbrellabirds, which are larger, have a puffy crest, and are much less vocal.
