they have a special tactic to hide themselve
The groundhog lives in a den or burrow. They hibernate during the winter. Actually groundhogs may dig as many as six or seven dens taking advantage of the food in the area.
Groundhogs, or woodchucks, typically give birth to their young in a burrow during the spring after a gestation period of about 31 to 32 days. A mother groundhog usually has a litter of 2 to 6 pups, which are born blind and hairless. She nurses them for about 4 to 6 weeks, during which she stays close to the burrow to protect them from predators. After weaning, the young groundhogs begin to venture outside the burrow, learning to forage for food before becoming fully independent by late summer.
When a groundhog digs a burrow, it displaces the dirt, which is typically pushed out of the hole and forms a mound or pile around the entrance. This mound of dirt can help provide a barrier against predators and can also serve as a marker for other groundhogs. The groundhog uses the burrow for shelter, nesting, and hibernation, so the dirt removal is essential for creating a safe living space.
Groundhog Day is celebrated on February 2 in the US and Canada. According to folklore, if a groundhog emerging from its burrow on this day fails to see its shadow, it will leave the burrow, signifying that winter will end soon. If the groundhog sees its shadow, the groundhog will supposedly retreat into its burrow, and winter will continue for six more weeks.
When a groundhog feels threatened, it typically seeks safety by quickly retreating to its burrow or a nearby hiding spot. They may also emit a series of loud warning calls to alert other groundhogs in the area of potential danger. If cornered, a groundhog may stand its ground and display aggressive behavior, such as hissing or growling, to deter predators.
Groundhogs are one of the few species that enter into true hibernation, and often build a separate "winter burrow" for this purpose. This burrow is usually in a wooded or brushy area and is dug below the frost line and remains at a stable temperature well above freezing during the winter months.
Winter is just as long to a groundhog as to us, but supposedly, groundhogs can predict the season changes. According to the legend, if the groundhog on leaving its burrow does not see his shadow, it will leave the burrow , which it means that winter will soon end. If, however, it "sees his shadow" and is frightened, it will go back into the Burrow, meaning that winter will last six more weeks.
Normally just one at a time, with multiple entrances.
A groundhog typically digs one main entrance to its burrow, but it often creates multiple secondary entrances or escape routes. These additional entrances help the groundhog quickly exit if threatened by predators. The burrow system can be extensive, with several chambers for sleeping, nesting, and hibernating.
When a groundhog emerges from its burrow, it typically checks its surroundings for signs of danger, such as predators. If the weather is mild and it feels safe, it may forage for food, primarily consisting of grasses, leaves, and vegetables. The groundhog's behavior upon emerging can also indicate whether it has seen its shadow, which is famously linked to the folklore of Groundhog Day predicting the length of winter.
The North American Groundhog takes approx. 3.5 minutes to dig a 3 Ft. burrow.
