Groundhog

The groundhog, also known as a woodchuck, whistle-pig, or in some areas as a land-beaver, is a rodent of the family Sciuridae, belonging to the group of large ground squirrels known as marmots. Other marmots, such as the yellow-bellied and hoary marmots, live in rocky and mountainous areas, but the woodchuck is a lowland creature. It is widely distributed in North America and common in the northeastern and central United States. Groundhogs are found as far north as Alaska, with their habitat extending southeast to Alabama.
In the wild, groundhogs can live up to six years, with two or three being average. In captivity, groundhogs are reported to live from 9-14 years, with the original Wiarton Willie being said to have lived for 22. Common predators for groundhogs include wolves, coyotes, foxes, bobcats, bears, large hawks, and dogs. Young groundhogs are often at risk for predation by snakes, which easily enter the burrow.
