The Amazonian Umbrellabird is a large, bizarre cotinga of the Amazon basin. Its namesake umbrella-like crest is distinctive in all plumages, although it is larger and more conspicuous in males. Males also have a long, feathered wattle dangling off their chests. Birds can sometimes be spotted as they forage at upper levels in the forest for fruit and arthropods, but the species is more often seen in lumbering flight over rivers or openings, its crest pushed back into a spike on the back of the head. The deep, booming call of the male carries can be heard at some distance. The Amazonian Umbrellabird occurs both in the foothills of the Andes and in the adjacent lowlands; it is not known whether the foothills populations are in direct contact with those in the lowlands, or if the populations are somewhat disjunct.
