During the winter, skunks mostly huddle in their dens for warmth. While skunks do not hibernate, they do become significantly idler once temperatures begin to drop. The answers to these questions have as much to do with skunk behavior as they do with other environmental factors that are within your control. But what about the colder months? Can you encounter skunks in winter? Do skunks hibernate, or are they just as active? Are they likely to join you on your property to escape the cold? Any dog owner who has tried to wash the smell of skunk musk off a sprayed pet knows how persistent and pervasive that odor can be.ĭuring the spring and summer when families and their pets are more active outside, skunk encounters are more common. Bears, raccoons, and skunks are all 'light hibernators' that use torpor to survive the winter.Skunks can be among the most unpleasant of unwanted animal guests. Bees, snakes and some bats are also hibernators. Whether an animal hibernates or enters torpor has a lot to do with the size of the animal, smaller animals tend to hibernate and larger animals tend toward torpor.Īnimals that are true hibernators include rodents like chipmunks, deer mice, woodchucks and ground squirrels.

Females bears awaken from torpor to give birth. The energy lost is offset by how much energy is saved in the torpid state. Waking expends energy and involves violent shaking and muscle contractions, much like shivering. The main difference between hibernation and torpor is during torpor, the animal is able to wake up quickly to avoid danger, or if the opportunity exists exit the den to feed. But while they are inactive, they enter into a deeper than normal sleep that allows them to conserve energy and survive the winter. During their active period of the day, animals in torpor maintain a normal body temperature, breathing and heart rate.

Unlike hibernation, torpor is not voluntary and often lasts for shorter periods of time. Bears can sleep more than 100 days without eating, drinking, or passing waste! Bears can actually turn their pee into protein. A bear’s body temperature reduces slightly. Torpor also involves decreased breathing and heart rates, and lower metabolic rate. Like hibernation, torpor is a survival tactic used by animals to survive the winter months, and is triggered by colder temperatures and decreased food availability. Many animals once thought to hibernate, including bears, really only enter a lighter sleep-state called torpor. Waking takes time and uses up an animal's energy reserve. Many, like the chipmunk, wake up for brief periods, but for the most part, true hibernators remain in this low-energy state through the winter. Before hibernating, animals generally store fat to help them survive the winter. Hibernation is triggered by decreasing day length and hormonal changes in an animal that dictate the need to conserve energy. Chipmunks do not sleep through the entire winter however, they wake every few days to feed on stored food and to urinate and defecate. Chipmunks reduce their heart rate from the usual 350 beats per minute to an almost undetectable 4 beats per minute during hibernation.

Hibernation can last days, weeks, or months depending upon the species. During hibernation an animal lowers its body temperature, slows its breathing rate, heart rate, and metabolic rate-the rate its body uses energy. Hibernation is a voluntary state an animal enters to conserve energy, when food is scarce, and minimize exposure to the winter elements. Bears enter a lighter state of sleep called torpor. However, not many animals truly hibernate, and bears are among those that do not. When we think about strategies animals use to survive the winter, we often picture birds flying south and bears hibernating in caves. Other animals settle in for a long winters nap. The snowshoe hare takes it even further, their thicker winter coat matches the color of snow, an adaptation known as camouflage. Some migrate to areas less effected by cold, some resist or adapt to withstand the effect of winter events, growing a thicker coat of fur for example. Animals have developed many strategies to survive the winter, a time when food and water are scarce.
