White-winged Guan

The White-winged Guan is a large critically endangered species of bird found in northwestern parts of Peru where it lives in ravine habitats. They feed on plant material like fruits, flowers, leaves, and seeds.

White-winged Guans have a mostly black plumage, with a green iridescence. The wing primary feathers are white, giving the species its common name. The bare skin on the face is purple and it has a reddish wattle.

It was thought to be extinct before being rediscovered in 1977. There were no known records of the bird being alive for about a hundred years prior to rediscovery. As of 2017 the species is considered to be critically endangered with threats including habitat destruction and hunting.

From IUCN Red List:
The White-winged Guan is listed as Critically Endangered on the IUCN Red List and was last assessed in 2015 by BirdLife International. This species qualifies as Critically Endangered because it has an extremely small population with a severely fragmented distribution. Awareness campaigns directed at local people, further surveys and concerted conservation action (the beginnings of which are apparent) appear to be improving its status such that the population may have ceased to decline. If this is confirmed, the species may warrant downlisting in the future.
