White-backed Woodpeckers can be distinguished from the more common Great Spotted Woodpecker by the pure white patch on their lower back and rump, the more extensive reddish colouring on their lower belly and vent, and the narrow streaks running along their flanks. Their mainly black wings have distinct white bands. Their facial markings include black moustache-like stripes that do not extend back as far as the nape. Males and juveniles have red caps, but females have black caps. White-backed Woodpeckers have dark grey legs and beaks, and reddish brown irises.
