In winter, bats, ground squirrels, marmots, jumping mice, bears and other true hibernators become inactive. By entering a state of deep dormancy they lower their body temperature to just above freezing and reduce their activity for several weeks. Fat accumulated throughout the summer provides vital energy during hibernation.
