Groundhog Day is on its way, when dozens of towns across the country look to local groundhogs to determine how long winter weather will wait around. With the meteorological swings DuPage County has experienced this season, surely no one would blame local groundhogs if they rejected the whole weather-predicting business and stayed in their underground dens on their big day. And they could count on the Forest Preserve District of DuPage County to support their right to hibernate in peace.
The District does not hold such an event because local groundhogs, also known as woodchucks, have yet to naturally wake up from hibernation by Feb. 2. The farther north a groundhog lives, the earlier it begins hibernation and the later it awakes from that state. In DuPage County, groundhog hibernation begins in late October or early November and ends in late February or early March, depending on environmental factors such as snow and temperature.
Waking a groundhog before it would emerge naturally can cause a threat to the animal’s health. “During hibernation, a groundhog’s heartbeat, metabolism and respiration slow, allowing it to live on its body fat,” explains Sandy Fejt, site manager at Willowbrook Wildlife Center, the District’s wildlife rehabilitation and education center. “If a groundhog is awakened from hibernation too early, it might not have the energy to find food and survive in cold winter temperatures.”
Fejt goes on to note that most towns’ prognosticating mammals are captive creatures that are not harmed by their participation in Groundhog Day celebrations. Willowbrook Wildlife Center does have a groundhog among its dozens of permanently injured animal residents, but he’ll most likely be snoozing on his species’ big day. “At Willowbrook, we strive to help visitors learn how our wild animal neighbors behave in their natural settings,” Fejt explains.
Groundhog Day marks the halfway point between the winter solstice and the vernal (spring) equinox. What started as a remnant of pagan festivals of rebirth and renewal and a Christian holiday known as Candlemas Day turned into a day of weather prediction. Legend has it that if the groundhog emerges from its hibernation hole on Feb. 2 and sees its shadow, there will be six more weeks of winter. If no shadow appears, spring is expected to arrive soon. Around the world, the behavior of bears, hedgehogs and other animals has been taken as an indication of the coming of spring.
