Great Spotted Woodpeckers are black-and-white woodland birds found across Eurasia and parts of North Africa. They are only rare visitors to the United States. A red patch below the tail and broad white shoulder patches help distinguish them from familiar North American woodpeckers.
Hairy Woodpeckers have a long white stripe down the center of the back and a pale lower belly. Great Spotted Woodpeckers have two large white shoulder patches and red below the tail.
Why they get mixed upBoth are black-and-white woodpeckers with red on some birds, and Hairy Woodpeckers occur in Alaska.
