Hairy Woodpeckers are usually found in mature mixed woods around campgrounds and picnic areas. This robin-sized bird can be recognized by the vertical white stripe on its black back, and its long bill. Like most woodpeckers, the Hairy Woodpecker feeds on tree boring insects, berries, acorns and sap. These woodpeckers are very often confused with Downy Woodpeckers which have the same markings but are smaller in size and have a shorter bill.
