South Carolina, USA.
Usually treated as conspecific with C. cafer and C. mexicanoides owing to high level of interbreeding between taxa at their geographical boundaries, but here allowed species status on account of considerable phenotypic differences. Thus, present species differs from C. cafer on account of its black vs red moustachial stripe in male (3); presence of red nape fringe (ns); grey-pink vs pale grey face, neck sides, throat and upper breast (3); dull grey vs pale greyish-brown crown (ns); yellow vs red shafts of wing and tail feathers, with yellowish vs reddish basal undertail (3); broad hybrid zone from Alaska through the Great Plains (1). Races chrysocaulosus and gundlachi are morphologically close to auratus and clearly belong with this species, although the former has been mentioned as sometimes treated as a separate species#R. Four subspecies recognized.
