Downy Woodpecker

I think that Downy Woodpeckers are probably the best known woodpecker in most areas of the U.S. as they are found throughout most of the country and are generally quite common, often visiting trees in backyards. They are smaller than other North American woodpeckers including the look-alike Hairy Woodpeckers (size is not a good field mark as large Downy Woodpeckers are about the size of small Hairy Woodpeckers).
