C. sclateri is a synonym. Has hybridized in captivity with C. alberti and members of genus Penelope. Described form C. estudilloi now known not to be a hybrid involving present species (see C. alberti). Taxon pinima formerly regarded as a race of present species, but here separated as a full species on basis of AMNH 6482, a female, being much smaller than female fasciolata (wing 295 vs mean 349 mm, tail 302 vs mean 347 mm; n=6 fasciolata) (expected score: 3), much darker above with greatly reduced barring (almost absent on undertail) (2) and much paler below, virtually whitish vs rusty-buff on belly (2). Race grayi also distinctive, especially in strength of buff barring on female’s upperparts, but individual variation of this taxon appears considerable. Proposed race xavieri, described from a male of captive origin having ochre flanks and upper thighs#R, now thought to be possibly based on individual with a plumage aberration. Two subspecies recognized.
