Genus Procnias
Bearded Bellbird - There are two subspecies; the nominate taxon, P. a. averano, in northeastern Brazil and P. a. carnobarba in Venezuela, Trinidad, extreme northeastern Colombia, western Guyana and far northern Brazil.
Bare-throated Bellbird - Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. It is threatened by habitat loss and by poaching for cage birds. It raises the attraction of collectors because of the adult males's showy coloration and call - a sharp sound like that of a hammer striking an anvil or a bell, emitted by the male in the wild while it perches on a high branch in order to attract a mate. A fruit-eating species, it acts in the ecology of the Atlantic rainforest as a dispersor of seeds
Three-wattled Bellbird - One of four species of bellbird that live in Central and South America, the Three-wattled Bellbird is between 25 cm and 30 cm long. The body, tail, and wings of the male are uniformly chestnut-brown; its head, neck, and upper breast are white; and it has a black eye-ring, eye-stripe, and bill. Its name comes from the three worm-like wattles of skin that hang from the base of the bill. These wattles can be as long as 10 cm when extended during songs and interactions. The wattles remain flaccid even when extended. The male shakes the wattles, but otherwise they hang straight down; they are neither erectile nor under muscular control. The side wattles do not stick out to the sides and the central one is not extended directly skywards as shown on some old illustrations and specimens. The female bellbirds are smaller and less striking in appearance, being overall olive with yellowish streaking below, pure yellow vent and no wattles.
