ITIS Reports — Oreophasis derbianus ITIS (the Integrated Taxonomic Information System) is a source for authoritative taxonomic information on plants, animals, fungi, and microbes of North America and the world. The horned guan (Oreophasis derbianus) is a large, approximately 85 cm (33 in) long, turkey-like bird with glossy black dorsal plumage, red legs, a white iris, a yellow bill, and a red horn on top of its head. The breast and upper belly are white, and its long tail feathers are black with a white band near the base. Both sexes are similar. The young are duller with a smaller horn, and have a brown tail and wings. The only member species in the monotypic genus Oreophasis, the horned guan is distributed in humid mountain forests of southeastern Mexico (Chiapas) and Guatemala in Central America. It is found at altitudes up to 3,350 m (10,990 ft). Its diet consists mainly of fruits, green leaves, and invertebrates. The female usually lays one or two eggs. The horned guan is not a true guan, but merely resembles these birds most in overall shape and color, whereas the horn is more reminiscent of the helmeted curassows. In fact, this species is the only survivor
