Ochre-backed Woodpecker (Celeus ochraceus)

Male.

It was previously always considered as a subspecies of the blond-crested woodpecker but the authors of a molecular phylogenetic study published in 2015 argued that it should be treated as a distinct species. This recommendation was accepted by the International Ornithologists' Union and the online edition of the "Handbook of the Birds of the World", but the South American Classification Committee of the American Ornithologists' Union has yet to rule on its status.
