Crax globulosa


, 1825,

Rio Solimões, Brazil


C. carunculata and C. yarrellii are synonyms. A close relationship between present species and C. blumenbachii has been claimed, especially because of very similar male plumages, and genetic data do indicate that the two species are each other’s closest relatives#R; nevertheless, vocal differences between them are considerable. Present species has hybridized in captivity with C. alberti. There are high levels of gene diversity in present species, as well as a small amount of genetic differentiation among populations#R. Monotypic.


Scattered sites in Amazon Basin in W Brazil (E to R Madeira), SE Colombia (in Amazonas and perhaps elsewhere), E Ecuador (probably extirpated), NE Peru and N Bolivia; range very incompletely known.
