Squirrels are generalist species found throughout Wisconsin. Gray (right) and fox (left) squirrels are generally 1-2 feet long, including their tail, and are commonly seen in hardwood forests. Red squirrels (pictured below right) are much smaller, with a deeper red coat, and are generally found in pine forests. Flying squirrels (below left) are a protected species. They are nocturnal and are rarely seen, and are sleek with an olive-brown coat. While squirrels can be entertaining to watch and enjoy, they also can be a nuisance, destroying gardens and lawns, and getting into buildings to eat stored seeds or gnaw on wiring.
