When do groundhogs hibernate?

We usually leave our summer dens by late August or early September to find our winter dens. We begin hibernation in late September or October. During hibernation, we fall into a very deep sleep. When it gets really cold, our body temperature will drop to just below freezing, and our heart rate and breathing slows way down. Why Groundhog Day is celebrated on February 2 I don't know. We do not emerge from hibernation until March or sometimes even April (in colder areas). Remember, if the ground is white, we're outta sight!


So I think it might be best to let him alone for right now and if he's around in the spring and there are no babies I'll move him.
