Horned Guan

The horned guan is 75 to 85 cm (30 to 33 in) long. Its most distinctive feature is the tall, red, fleshy "horn" on its forehead. It has a small head, long strong legs, and a long broad tail. The sexes are alike in plumage but males have a taller horn and longer wings, tail, and legs than females. Adults have a glossy black head, neck, and upperparts with a bluish sheen. Their tail is black with a wide white band near its base. Their throat, breast, and upper belly are whitish with black flecks and their lower belly and flanks are brown. They have a small red dewlap, a white iris, a yellow bill, and red legs and feet. Juveniles resemble adults but are duller and have a smaller horn.

The horned guan is found in the southern Mexican state of Chiapas, possibly in Oaxaca, and in southern Guatemala. Reports from Honduras have not been confirmed. Its distribution is not continuous but highly local. 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. In elevation it mostly ranges between 2,300 and 3,100 m (7,500 and 10,200 ft) but locally occurs as low as 1,200 m (3,900 ft) and as high as 3,350 m (11,000 ft).

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 including the ground. Many seeds pass intact through its system, which suggests that it might be a significant dispersal agent.
