The groundhog (Marmota monax), also known as the woodchuck, is a rodent of the family Sciuridae, belonging to the group of large ground squirrels known as marmots. A lowland creature of North America, it is found through much of the Eastern United States, across Canada and into Alaska. It was given its scientific name as Mus monax by Carl Linnaeus in 1758, based on a description of the animal by George Edwards, published in 1743. The groundhog, being a lowland animal, is exceptional among marmots. Other marmots, such as the yellow-bellied and hoary marmots, live in rocky and mountainous areas. Groundhogs are considered one of the most solitary of marmot species. They live in aggregations, and their social organization and long-term pair bonds varies across populations. The groundhog's male and female interactions are usually limited to the mating season and copulation. However, certain populations of groundhogs have been observed to form long-term adult male-female association throughout the year, and often from year to year.
