Great Curassow

The Great Curassow is a very large game bird of tropical forest, eliminated from most areas by hunting. Rarely found except in protected parks or very remote areas. 

Usually seen on the forest floor, like in this image, either singly or in small groups, but also feeds in trees. Males often sing from high in canopy and their song is a very low-pitched, almost subliminal, booming sound.

Both sexes have distinctive curly crest. Female plumage is variable: some have bold barring, others have darker and mostly unbarred plumage. Cornell All About Birds
