The horned guan is a large, approximately 85 cm long, turkey-like bird. is distributed in humid mountain forests of southeast Mexico-(Chiapas) and Guatemala of Central America. Its diet consists mainly of fruits, green leaves and invertebrates. This species is the only survivor of a very ancient lineage of cracids that has been evolving independently from all other living members of this family for at least 20, possibly as much as 40 million years. Due to ongoing habitat loss, small population size, limited range and hunting in some areas, the horned guan is evaluated as Endangered on the IUCN Red List of Threatened Species.
