based on a cagebird of unknown origin.
Formerly included C. daubentoni as a race. Form C. annulata was described from a female of the rare barred morph and an immature male of present species. Has hybridized in captivity with C. rubra and C. fasciolata, producing birds with green cere; also with C. globulosa, Penelope pileata and Mitu tuberosum. Form C. viridirostris, with green cere, thought to have been described from an abnormal specimen of present species or from hybrid between it and another member of genus, now shown by mtDNA-sampling to be an aberrant C. daubentoni or a hybrid between latter and another Crax#R#R; on the other hand, the morphologically similar specimen described as C. estudilloi, from an aviary bird in Mexico reputedly acquired in Bolivia, was found to be an aberrant C. alberti, although it may have been the offspring of a mixed pairing between a female of present species and a congener#R#R. Monotypic.
N Colombia; currently survives only in a few remnant forest patches from La Guajira and Magdalena S to Antioquia and W Boyacá#R.
