The plumage of Hairy Woodpeckers is a mix of black and white (but see below). Its wings, lower back, and tail are black with white spots; its upper back and outer tail feathers are white. Its underside is white, and its head is marked with wide alternating black and white stripes. Males have a red spot at the backs of their heads which females lack. Hairy Woodpeckers closely resemble Downy Woodpeckers but are larger and have much longer bills.
