Three-toed Woodpeckers are smaller and darker than the more familiar Great Spotted Woodpecker. Distinguishing features include a long white patch running down the back, black and white bands on head, and dark crosswise striping on underparts. Additionally, Three-toed Woodpeckers have no red colouring in their plumage. Juveniles and males have yellow caps.
Three-toed Woodpeckers’ legs are dark. As the species’ name indicates, they have only three toes on each foot (other woodpeckers have four). Their beaks are dark bluish grey with a black tip, and their irises may be blue and white (adults) or brown (juveniles).
