Scientific Name: Melanerpes formicivorus
Few birds are named after their primary food source, but in the case of the Acorn Woodpecker, it makes perfect sense. Groups of Acorn Woodpeckers collect acorns communally, and store them in oak trees riddled with small holes excavated for this purpose. A single large oak tree can contain thousands of stored acorns that can later be consumed by the woodpeckers.
If you spend some time outside looking for woodpeckers, you will notice that you usually see only one or two of the same species at a time. However, if you visit the West Coast or the southwestern U.S. where Acorn Woodpeckers can be found, you are likely to see anywhere from several birds to more than a dozen all visiting the same tree to store acorns.
