Recent molecular study found this species to form a monophyletic group with C. elegans and C. lugubris#R; has sometimes been treated as conspecific with C. lugubris. Until recently, considered conspecific with C. ochraceus, as intergradation of two taxa and intermediate form intercedens suggest morphological and geographical convergence, but differs in its pale plumage coloration of whitish-buff vs orange-ochre (2); pale barring on upperparts much narrower and not broken up into scaling and dotting (3); considerably larger size, on basis of published measurements#R in which no overlap in ranges of values for bill, wing, tail or tarsus (allow at least 2); also, zone of intergradation (e.g. SW Bahia to Espírito Santo) (at least 1). Recent molecular evidence supports species status for present form, although study failed to sample intercedens, which “some populations of C. ochraceus closely resemble”#R; more research on situation in intervening areas between taxa required. Described form roosevelti was in the past sometimes treated as a race of present species, but now regarded as hybrid probably between C. elegans jumanus and C. lugubris. Two subspecies recognized.
