From Wikipedia: Arizona Woodpeckers grow to be about 20cm in length. Their plumage is mainly brown and white in coloration, brown on top with a dark rump with white underparts speckled with brown spots. Arizona Woodpeckers usually have white bars on their wings, and have two white stripes across their face which join with another white bar on their neck. Male Arizona Woodpeckers also have a red patch on the nape of their head which is lacking on females.
