Large and dramatic, horned guans are predominantly glossy black, with a unique horn of bare skin extending from the top of their head. About the size of a small turkey, horned guans are arboreal, meaning they prefer to spend their time in the trees and rarely come down to the ground. The guans feast mainly on fruit and leaves.

Horned guans build their nests high in the leafy tree branches, some reaching up to 66 feet off the ground. Males will mate with several females, with each hen producing two eggs in a clutch. Their incubation period is one of the longest documented in their family of cracids, lasting approximately 36 days.

Only 1,000-2,000 horned guans now exist in the wild. Their woodland habitat is being cleared by loggers and coffee farmers, who often clear entire hillsides at a time. Guans are also a source of much-needed protein and are being hunted for food.
