Forms superspecies with C. aeruginosus, C. maillardi, C. spilonotus and C. approximans; sometimes all considered conspecific, but present species differs from closest ally, C. aeruginosus, in some aspects of plumage and morphology, probably in breeding behaviour and display, and in lack of pronounced sexual dimorphism in plumage.
