To survive the winter, they are at their maximum weight shortly before entering hibernation. When the groundhog enters hibernation, there is a drop in body temperature to as low as 35 degrees Fahrenheit (2 °C), heart rate falls to 4–10 beats per minute and breathing rate falls to one breath every six minutes. During hibernation, they experience periods of torpor and arousal. Hibernating woodchucks lose as much as half their body weight by February. They emerge from hibernation with some remaining body fat to live on until the warmer spring weather produces abundant plant materials for food. Males emerge from hibernation before females. Groundhogs are mostly
895:(51–91 cm) below ground surface. It is about 16 inches (41 cm) wide and 14 inches (36 cm) high. There are typically two burrow openings or holes. One is the main entrance, the other a spy hole. Description of the length of the burrow often includes side galleries. Excluding side galleries, Schoonmaker reports the longest was 24 feet (7.3 m), and the average length of eleven dens was 14 feet (4.3 m). W. H. Fisher investigated nine burrows, finding the deepest point 49 inches (120 cm) down. The longest, including side galleries, was 47 ft 11.5 in (14.62 m). Numbers of burrows per individual groundhog decrease with 707:) than when they emerge from hibernation in spring. Adult males average year-around weight 3.83 kg (8 lb 7 oz), with spring to fall average weights of 3.1 to 5.07 kg (6 lb 13 oz to 11 lb 3 oz) while females average 3.53 kg (7 lb 13 oz), with spring to fall averages of 3.08 to 4.8 kg (6 lb 13 oz to 10 lb 9 oz). Seasonal weight changes reflect circannual deposition and use of fat. Groundhogs attain progressively higher weights each year for the first two or three years, after which weight plateaus. 785: 625: 1364: 990: 916: 172: 1252:. A percentage of the woodchuck population is infected with the woodchuck hepatitis virus (WHV), which is similar to human hepatitis B virus. Humans cannot contract hepatitis from woodchucks with WHV, but the virus and its effects on the liver make the woodchuck the best available animal for the study of viral hepatitis in humans. The only other animal model for hepatitis B virus studies is the chimpanzee, an endangered species. Woodchucks are also used in biomedical research investigating 981:. As birth of the young approaches in April or May, the male leaves the den. One litter is produced annually. Female woodchucks give birth to one to nine offspring, with most litters ranging between 3 and 5 pups. Groundhog mothers introduce their young to the wild once their fur is grown in and they can see. At this time, if at all, the father groundhog comes back to the family. By the end of August, the family breaks up; or at least, the larger number scatter, to burrow on their own. 147: 1034: 870: 750: 350: 115: 1152:

Groundhogs are well-adapted for digging, with powerful, short legs and broad, long claws. The groundhog's tail is shorter than that of other sciurids—only about one-fourth of body length. 1065:). Many of these predators are successful stealth stalkers that catch groundhogs by surprise before they can escape to their burrows; badgers likely hunt them by digging them out from their burrows. Coyotes in particular are sizable enough to overpower any groundhog, with the latter being the third most significant prey species per a statewide study in 884:. Groundhog burrows usually have two to five entrances, providing groundhogs their primary means of escape from predators. The volume of earth removed from groundhog burrows in one study averaged 6 cubic feet (0.17 m) per den. The longest burrow measured 24 feet (7.3 m) plus two short side galleries. 757:
