White Bellbird

The white bellbird (Procnias albus) is a species of bird in the family Cotingidae, the cotingas. It is found in Brazil, French Guiana, Guyana, Suriname, Venezuela, and as a vagrant to Trinidad. == Taxonomy and systematics == The white bellbird has two subspecies, the nominate P. a. albus (Hermann, 1783) and P. a. wallacei (Oren & Novaes, 1985). It shares genus Procnias with three other species; it and the three-wattled bellbird (P. tricarunculatus) are sister species. The species' specific epithet has often been spelled alba, but albus is correct due to the masculine gender of Procnias. == Description == The white bellbird is about 27 to 29 cm (11 to 11 in) long; males weigh 210 to 222 g (7.4 to 7.8 oz). The species is dramatically sexually dimorphic though both sexes have a short bill that opens very wide. Males are unique. Females resemble female bearded bellbirds (P. averano). Adult males of the nominate subspecies have entirely white plumage. They have a single black wattle with a few white feathers that drapes from the base of the maxilla. Females do not have a wattle. Adult females have an olive-green head and upperparts. Their wings and tail are also olive-green…
