Yungas manakin
The Yungas manakin is a species of bird in the family Pipridae. It is found in Argentina, Bolivia, and Peru.
Taxonomy and systematics
The Yungas manakin was originally described in 1889 as Chiroxiphia pareola boliviana, a subspecies of the blue-backed manakin. A study published in 1987 noted how it differed in morphology, song, and courtship display from C. pareola ''sensu stricto''. Following the study's suggestions, taxonomic systems elevated it to species rank with its current English name.The Yungas manakin is monotypic.
Description
The Yungas manakin is long and weighs about. The species is sexually dimorphic, though both sexes have a short tuft of feathers on the forecrown. Adult males have a small dark red patch in the center of their crown and a pale blue back. The rest of their plumage is black. Adult females have olive-green upperparts with browner wing coverts and flight feathers. Their underparts are a paler green that becomes paler still on the lower belly and undertail coverts. Both sexes have a brown, gray-brown, or reddish brown iris, a black or blackish bill, and highly variable purplish brown to pale yellowish cream legs and feet.Distribution and habitat
The Yungas manakin is found along the eastern slope of the Andes from Cuzco Department in southern Peru south through Bolivia into far northern Argentina. There are also a few records further north in Peru's San Martín Department. The species' range extension into Argentina appears to be relatively recent. The IOC and Clements taxonomy ranges do not include Argentina but the independent South American Classification Committee has records in that country.The Yungas manakin is true to its name; its range is entirely within the Yungas biome. It inhabits humid montane forest, where it apparently favors the edges with fruiting trees. In elevation it ranges between in Peru and between in Bolivia. One individual apparently wandered up to.
