From the angle of the shot, I can't see red or yellow coloring on the under wing so i'll have to chalk it up to being a Northern Flicker but it is either the Red shafted or the gilded Flicker.
Could also be a downy
The woodpeckers, piculets, wrynecks, and sapsuckers are a family, Picidae, of near-passerine birds. Members of this family are found worldwide, except for Australia, New Guinea, New Zealand, Madagascar, and the extreme polar regions. Most species live in forests or woodland habitats, although a few species are known to live in treeless areas, such as rocky hillsides and deserts.
