Woodchucks, also known as groundhogs, are medium-sized rodents belonging to the family Sciuridae. They are primarily found in North America and are known for their burrowing habits. Woodchucks have a stocky body, short legs, and a bushy tail, typically weighing between 5 to 14 pounds. They are herbivores, feeding on grasses, fruits, and vegetables. These animals are most active during the day, especially in the spring and summer. Woodchucks hibernate during the winter months, retreating to their burrows to conserve energy. They are also famous for their role in Groundhog Day, a popular tradition in the United States.
