Hairy woodpeckers are found throughout North America in mature forest and wooded areas. They are a black and white woodpecker with a white back patch, white spots on the wings, and a large bill. The males have a red patch on the back of the head, while the females lack the red. Downy woodpeckers are almost identical, except the are smaller in beak and overall size. Hairy woodpeckers eat mostly insects and are a big help in controlling bug populations. They will also eat fruit, seeds, and suet.
