Endangered
Horned Guan
Oreophasis derbianus
The horned guan is an endangered species in an ancient group of birds of the family Cracidae, that are related to the Australasian megapodes or mound builders (Megapodiidae).
Appearance
Its most distinctive feature is the tall, red, fleshy "horn" on its forehead. The sexes are alike in plumage but males have a taller horn and longer wings, tail, and legs than females. Their tail is black with a wide white band near its base.
The horned guan is 75 to 85 cm (30 to 33 in) long.
Range and habitat
The horned guan is found in the southern Mexican state of Chiapas, possibly in Oaxaca, and in southern Guatemala. It inhabits humid subtropical montane evergreen forest, cloudforest, and pine-oak forest. Its habitat is characterized by much undergrowth of tree ferns, epiphytes, mosses, and vines.

Diet and breeding
The horned guan feeds mostly on a very wide variety of fruits. Green leaves are a significant part of its diet with flowers and possibly insects eaten in small amounts. It forages singly or in small groups at all levels of the forest among them the ground.
Most of the information about the horned guan's breeding biology comes from Mexico in a study published in 1995. Its breeding season appears to span at least from January to March. Its nest is an oval structure of dry leaves and roots place high in a tree and usually near running water.
