Feared extinct for nearly a century until its dramatic rediscovery in 1977, the White-winged Guan has been the subject of an intensive captive-breeding and conservation campaign. This species is endemic to the foothills of the Tumbesian region in northwestern Peru, where it occurs in dry deciduous forest on slopes and in ravines. This is a distinctive member of the genus Penelope that has relatively dark plumage that contrasts with the namesake white primary patches. It feeds primarily on fruits but takes a variety of foods on occasion. Hunting and habitat destruction continue to threaten this species, but conservation efforts have made some headway in stabilizing its population.
