The Red-billed Curassow, Crax blumenbachii, is an endangered species of Cracid that is endemic to lowland Atlantic Forest in the states of Espírito Santo, Bahia and Minas Gerais in southeastern Brazil. Its population is decreasing due to hunting and deforestation, and it has possibly been extirpated from Minas Gerais. It is currently being reintroduced to Rio de Janeiro by means of individuals bred in captivity. As suggested by its common name, the male has a largely red bill, but this is lacking in the female.
