Chachalacas, Guans and Curassows (Cracidae)

Red-billed Curassow (Crax blumenbachii) - HBW 2, p. 362

French: Ortalide à tête grise German: Rotschnabelhokko Spanish: Pavón Piquirrojo
Other common names: Blumenbach's/Red wattled Curassow

Taxonomy: Crax blumenbachii Spix, 1825, state of Rio de Janeiro.
All members of genus form superspecies. In past, the sexes were thought to constitute two different species; male was described as "C. rubrirostris". A close relationship has been claimed between present species and C. globulosa, especially because of very similar plumage of males; but voice very different and precludes the possibility of their being conspecific. Monotypic.

Distribution: SE Brazil. Formerly fairly widespread from S Bahia S to NE Rio de Janeiro; currently restricted to a few scattered forest patches. One record from Bolivia repeatedly claimed to refer to present species, but erroneously.
