The bare-throated bellbird (Procnias nudicollis) is a species of bird in the family Cotingidae.
The male bird has striking white plumage and a patch of bare blue-black skin around the eyes, beak and throat.
Like other bellbirds (Procnias), the beak of P. nudicollis has a short bill with a very wide opening.
The male has one of the loudest calls of any bird: a high-pitched sound like a hammer striking an anvil or bell. Before making such a call, an individual should inhale deeply to increase the air pressure in the interclavicular air sacs.
The bare-throated bellbird is native to Brazil, Paraguay and Argentina.[1]
Unlike many other cotingids, they migrate seasonally to different altitudes in Paraguay and eastern Brazil depending on fruit production and the age class of the migrating individuals.
Its natural habitats are tropical or subtropical moist lowland forests and subtropical or tropical moist montane forests.
Despite its vulnerable condition, a young male was photographed in 2007 searching for food on one of the campuses of the Federal University of Rio de Janeiro, an unusual urban environment located on an artificial island in the vicinity of the heavily polluted Guanabara Bay.
