Birds showing notable sexual dimorphism ranging from South America to Central America

The large pheasant-like birds with curly crests and crissum are contrastingly colored with the white and reddish-brown combination. Males are more brightly colored than females. Great curassow is the massive and heaviest member of the genus.

They are commonly found in small groups and build their small oval-shaped nests in trees, except for the Blue-billed curassow, which makes large nests from sticks and dead leaves. The female usually lays a clutch of two eggs in the nest.

The ground-feeding birds of the genus prefer semi-deciduous and moist habitats as they feed on worms, seeds, fruits, small leaves, and insects. The species of the genus readily hybridize and produce fertile offspring.
