Red-billed Curassow Crax blumenbachii

The Red-billed Curassow, sometimes called Red-knobbed Curassow, was native to lowland Atlantic forest of southeast Brazil but has been exterminated from much of its former range by deforestation and hunting. The remaining, declining populations are critically endangered.

In addition to the red on the black bill, the male has glossy iridescent black plumage with a white underbelly (the similar-looking Wattled Curassow has a russet underbelly). The female does not have the red portion on the bill and has a russet underbelly and rear wings.
