Ochre-backed Woodpecker formerly was classified as a subspecies of Blond-crested Woodpecker (Celeus flavescens). Both species have a blond, crested head, and the males of both have a large red moustachial stripe, while females have a less prominent black moustache. The body plumage differs significantly, however: Blond-crested is mostly black, with a buffy rump, and narrow buff bars across the wings and the back; but in Ochre-backed, the underparts are dusky, although the feathers are tipped with cinnamon-buff, and the upperparts are predominately cinnamon-buff, spotted or streaked with blackish. Different as they are, these two species are reported to hybridize in eastern Brazil in Espírito Santo and southern Bahia. A further complication is that one subspecies of Blond-crested Woodpecker, intercedens, which occurs in the interior of eastern Brazil, is intermediate in appearance between the two. subspecies. Ochre-backed Woodpecker is a poorly known species of Celeus, although its biology probably is similar to that of other members of the genus.
