This is a male Yellow-shafted Northern Flicker. The males have a black stripe extending from the bill to the neck. This stripe is absent in the female. Both sexes have the red mark on the back of the head, which this one shows us, below. Notice the yellow feathers in the wing and the underside of the tail which gives this species the "yellow-shafted" name.
These are male Red-bellied Woodpeckers. They are year-round residents of the eastern half of the USA from the Gulf of Mexico to the southern Great Lakes.
The red area on the back of the neck extends only to the back of the head on the female, but goes clear over the top and down to the bill on the male Red-bellied Woodpecker. Notice in the picture above the reddish area on the belly for which this species is named.
