Facts about this animal
The Horned Guan has a dull white breast, with conspicuous blackish midstreaks on the feathers. The rest of the plumage is black. It has a conspicuous white bar across the middle of the tail. The belly is dull black with scattered whitish edgings of the feathers. The upper surface of the wings and tail has a dark bluish or greenish-blue sheen. The head, neck and throat are velvety black, the feathers fo the forehead are very plushlike, covering the cere and the nostrils. The hindneck has a dark bluish or greenish-blue sheen.
The horn is bony, upright, nearly cylindrical and scarlet, arising from the brightly coloured bare part of the crown. In msles, it is up to 55-60 mm in high, in females up to 45 mm. The bill is horn or straw coloured and the eyes are conspicuously white. It has orange-red to vermillion coloured legs.
Horned guans are arboreal and rarely come down to the ground. They feed mainly on fruit and leaves.
Horned guans build their nests high in the leafy tree branches, some reaching up to 20 m off the ground. Males will mate with several females. Each hen will produce two eggs in a clutch, which she will incubate for about 36 days, which is one of the longest documented incubating periods in the Cracidae family.
