North America's largest living woodpecker is the Pileated Woodpecker. They are roughly the size of a crow with a beak that can do some damage. Woodpeckers have a very specific set of tools that they use to extract breakfast from the trees they cling to. The toes of most woodpeckers are arranged in a two up and two back set up which allows for a much better hold on the trees they cling to. They also have a tongue that is extremely long in order to reach into holes hiding their food. So long that they need a special way to keep all that tongue in their heads seen here.
