Neotropical bellbird (or simply bellbird) is the common name given to passerine birds of the genus Procnias, found in the Neotropics. They are members of the cotinga family. In some parts of their range, they are sometimes referred to as "araponga". They are all restricted to tropical or subtropical humid forested regions, often in low mountains or foothills. As indicated by their common name, they all have very loud voices.
Three of the four species are restricted to South America, while the last, the three-wattled bellbird, is restricted to southern Central America.
They are strongly sexually dimorphic. Males have an at least partially white plumage, and facial wattles or bare facial skin. Females lack the wattles/bare facial skin, and are overall olive with yellowish streaks below.
The Bearded Bellbird (Procnias averano) also known as the campanero or anvil-bird, is a passerine bird which occurs in northern South America. The male is about 28 cm (11 in) long with white plumage apart from a brown head and black wings. At his throat hang several black, unfeathered wattles. The female is a little smaller with olive-green head and upper parts, yellow underparts streaked with green and a yellow vent area. The male has a loud, repeated metallic hammering call, as well as various other vocalisations.
There are two subspecies, the nominate subspecies is only found in northeastern Brazil, while the other subspecies occurs in Tobago, Venezuela, Colombia, Guyana, eastern Bolivia and northern Brazil. This bird is found in moist tropical forests where it feeds mainly on fruit and berries which are picked on the wing. The nest is a rather flimsy mass of stems and slender twigs built far out on a branch of an isolated tree. A single buff-colored egg is laid and incubated solely by the female.
Like other cotingas, the bearded bellbird has a broad hooked-tipped bill, rounded wings, strong legs and a striking appearance. The male is approx 28 cm 11 in long, and weighs 180 g (6 1⁄2 oz). His plumage is white or greyish-white apart from the black wings and warm brown head. He sports a grotesque "beard" of un-feathered, black stringy wattles.
The female is smaller, and her upperparts are olive-green (duskier on the head), most of the underparts are yellow streaked with green, and the vent is pure yellow. She lacks the facial wattles ("beard"). Both sexes have dark eyes, a black bill and grey to black legs.
The males' advertising calls are a very loud dull Bock repeated every few seconds and a somewhat less loud, metallic hammering tonk-tonk-tonk-tonk. It sounds like a hammer rapidly hitting an anvil and is repeated 20-30 times. (see Videos).
The bearded bellbird is native to Trinidad and Tobago, Colombia, Guyana, Venezuela, Bolivia and northern Brazil where it occurs in humid forests and woodland. It is mainly resident, but some populations take part in altitudinal migrations; breeding at altitudes of up to 1,900 m (6,200 ft) and spending the non-breeding season in the lowlands.
These arboreal bellbirds feeds entirely on fruit and berries, mainly taken on the wing. Lauraceae and Burseraceae are particularly favored, and the young are fed regurgitated Lauraceae by the female.
