During the day they will often lay very still in a cool shady spot and nap. This behavior is seen even in captive squirrels. I made a hyperlink of the title for any that would be interested to view it!Įven during warm weather, squirrels are most active in the early morning and late afternoon. I made a video titled," How Squirrels Stay Warm In Winter ," that shows this communal sleeping arrangement exhibited by a pair of females I released a few years ago, along with some other facts about how they stay warm in winter. My suspicion is that it is divided upon sex lines, IE., females group together and males group together, because it has been my observation that females will not tolerate males at any time except mating season. ![]() Even though squirrels can be territorial, this rule is dropped when the weather turns bad. This communal sleeping arrangement carries over into adulthood, especially when it is bitter cold. If you have ever raised more than one baby squirrel, you know that they sleep in a ball of bodies and keep each other warm. It is a characteristic they learned when they were babies. This is the main way squirrels stay warm in Winter, and how they manage to survive during the coldest of Winters. When I say that they stay hunkered down with their friends during bitter cold weather, that's exactly what I mean. ( Yes, it is estimated that a squirrel will find and bury 3 years worth of food every Summer and Fall!) They are the ultimate survivalists! When there is a break in the weather, they will venture out to retrieve some of the three years worth of food they squirreled away during the Summer and Fall. Squirrels do not hibernate in winter, but they do not like bitter cold weather, so they will stay hunkered down in their den or drey when it is really cold, opting to stay warm with their friends rather than venture out. They are ready to produce offspring during the summer following their birth.The short answer is, "No, squirrels do not hibernate, but they do sleep a lot!" Complete weaning occurs after 2 months of age, by they often continue living for their mother until 3 months old. At about 40 days old, young squirrels leave the nest. Their fused toes separate by the 6th day of their lives, while the eyes open after 31 days old. They are extremely tiny and weigh only 5 - 6 grams at birth. The babies are born undeveloped with closed eyes and ears, fused toes as well as a cylindrical tail. Males usually don't participate in rearing the offspring. The gestation period lasts for 37 - 42 days, yielding 1 - 6 young with an average of 2 - 4 per year. They most likely have different mates during each breeding season, which means they may exhibit either polygynous (one male mates with multiple females) or polygynandrous (promiscuous) (both males and females have multiple mates) mating systems. ![]() The most commonly heard calls of this squirrel are soft, low chirping sounds and a cluck, which is emitted when the animal is feeling danger.Ĭurrently, there is very little information on the reproductive system of this species. Primary forms of communication include vocalizations, scent, and touch. ![]() Northern flying squirrels are terrestrial feeders, spending a lot of time looking for food. They are able to glide for as long as 5 - 45 meters at a time (20 average), though flights as long as 90 meters have been recorded. These rodents are one of the most aerodynamically sophisticated gliding mammals. ![]() Since they don't hibernate, multiple individuals may live in a single den during this period to conserve heat. The winter dens of this species are usually cavities in conifer trees. During the year, each individual may have several dens. They have two periods of activity during the day: one occurs an hour after sunset, lasting around 2 hours, whereas the other begins 2 hours before sunrise, lasting for 1.5 - 2 hours. Northern flying squirrels are strictly nocturnal animals. During the winter months, these squirrels gather into same-sex units in order to keep warm. In addition, multiple individuals have been known to live in the same nest. They often form groups of 8 individuals, typically including matures squirrels and juveniles. Northern flying squirrels are social animals.
