Habitat

Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.

Description

The bird measures an average of 73 centimeters in length and weighs an average of 1.2 kilograms, being very similar in appearance to its smaller relative, the rusty-margined guan (P. supercilliaris).

Diet

It eats fruit, flowers and buds taken from the ground or plucked from tree branches, and acts as a seed disperser for various species of trees and palms, such as the endangered palm Euterpe edulis, or the palms of the genus Syagrus (e.g. queen palm and licuri).[3]
