Groundhog Information

The groundhog (Marmota monax) is the largest member of the squirrel family. A groundhog is also called woodchuck or whistlepig. It has short legs, strong claws, and a stubby tail. Groundhogs are covered with two coats of fur. The outside fur keeps water out and the inside fur keeps in body heat. Groundhogs weigh between 4 and 14 pounds, and live most of their lives underground. The fox, wildcats, coyotes and hawks are their main natural enemies. Groundhogs are the only animals that have their own National holiday: Groundhog Day.
