Also known as a Woodchuck, this is a rodent belonging to the group of large ground squirrels. They are the largest members of the squirrel family. At about 20 inches long, Groundhogs weigh around 13 pounds. These mammals are found only in North America, from Canada down to the southern United States.
Groundhogs have sharp claws that they use to dig impressive burrows in the ground. Their burrows can be anywhere from 8 to 66 feet long, with multiple exits and a number of chambers.
Their favored habitat is woodland areas on the edge of open fields. Groundhogs are solitary creatures that can eat about a pound of food per sitting. A Groundhog’s diet can include fruit, plants, tree bark and grasses. One reason why they eat so much is because in the Winter they hibernate and live off their fat.
While hibernating, the Groundhog’s heartbeat slows from 80 beats per minute to 5 beat per minute; their respiration reduces from 16 breaths per minute to as few as 2 breaths per minute; and their body temperature drops from about 99 degrees Fahrenheit to as low as 37 degrees.
In February, males will come out of hibernation and search for females’ burrows. When he finds one, he heads on in. It is believed that males do this to introduce themselves to possible mates.
Groundhog Day is a popular tradition celebrated in the United States and Canada on February 2. It derives from the Pennsylvania Dutch superstition that if a groundhog emerging from its burrow on this day sees a shadow due to clear weather, it will retreat to its den and Winter will persist for six more weeks, and if he does not, due to cloudiness, Spring season will arrive early.
The Groundhog is also referred to as a Chuck, Wood-shock, Groundpig, Whistlepig, Whistler, Thickwood Badger, Canada Marmot, Monax, Moonack, Weenusk and Red Monk.
