Wellenbindenspecht

Bestimmung

The ochre-backed woodpecker is about 25 to 27 cm (9.8 to 11 in) long. Males have a wide dull red malar area and cheek; females have a streaky black malar instead of red. Adults of both sexes have a buffy or cinnamon-tinged ochre head including the long pointed crest, chin, throat, and neck. Their upperparts are cinnamon-buff to orange-ochre with black markings that vary in shape from round to heart-like. Their flight feathers are mostly black; the secondaries have wide cinnamon-buff bars and the tertials are cinnamon-buff with black bars and tips. Their tail feathers are black with pale buffish edges or bars on the outermost pair. Their underparts are sooty, often with buff-cinnamon feather edges, and the rear flanks and undertail coverts have wide cinnamon to buff bars. The adult's bill is horn-colored or sometimes blue-gray to blackish with a paler mandible, their iris red or red-brown, and their legs blue-gray. Juveniles are similar to adults but are duller and have more brownish black on their head.

Taxonomie

The ochre-backed woodpecker was long treated as a subspecies of the blond-crested woodpecker (C. flavescens), but following a 2011 publication, regional and worldwide taxonomic systems gradually moved to accept it as a full species. The ochre-backed woodpecker is monotypic.
