Male distinctive, and while his white patch on the secondary coverts identifies him as a sapsucker, he is patterned like no other sapsucker (or woodpecker). The female is somewhat more subtle, and is the only sapsucker to lack a white wing patch, but no other woodpecker shares her broadly pale back barred with brown and brown wings spotted with white.
