Recent molecular study found this species to be sister to the monophyletic group formed by C. flavescens, C. elegans and C. lugubris#R. Has sometimes been treated as conspecific with last of these. Usually treated as race of C. flavescens, as intergradation of two taxa and intermediate form intercedens suggest morphological and geographical convergence, but differs in its pale plumage coloration of orange-ochre vs whitish-buff (2); pale barring on upperparts much broader and more broken up into scaling and dotting (3); considerably smaller 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. Monotypic.
E Brazil from W Pará (S of Amazon) to Atlantic coast and S to E Bahia and Espírito Santo.
