The Andean guan (Penelope montagnii) - the most widespread species of guan in the Andes - is relatively small, similar in size to a chicken. The plumage is overall brown with whitish edging to the feathers of the head, neck and chest. It has a red dewlap (a flap of skin that hangs beneath the lower jaw) and reddish legs. It has long neck and tail, and partially feathered throat and tarsi. The Andean Guan is threatened by the destruction of the habitat through heavy deforestation and fragmentation in its altitudinal range, involving population’s decline.
