- Groundhogs are large ground squirrels known as marmots.
- They are widely distributed in North America and common in the northeastern and central United States.
- The groundhog is the largest sciurid in its geographical range.
- They are well adapted for digging, with short but powerful limbs and curved, thick claws.
- They can live up to six years, with two or three being average.
- Mostly herbivorous, they primarily eat wild grasses and other vegetation, including berries and agricultural crops, when available.
- They are excellent burrowers, using burrows for sleeping, rearing young, and hibernating.
- They usually breed in their second year, but a small proportion may breed in their first.
- Groundhog Day is a day celebrated on February 2. According to folklore, if it is cloudy when a groundhog emerges from its burrow on this day, then spring will come early.
