The Horned Curassow is a large bird of central Bolivian forests. A blue-grey casque rises above its red bill, and it feeds on fruit.
Glossy black plumage contrasts with the white belly and undertail. A blue-grey, horn-like casque sits at the base of the red bill.
Horned Curassows occupy humid Bolivian foothill forests and give deep booming songs.
A nest in Amboró held one egg. During nine observation days, the female incubated alone, leaving at night and returning near dawn.
Afternoon activity included preening and rearranging leaves and sticks in the nest.
