When Do Ground Squirrels Sleep?
Have you ever wondered when do ground squirrels sleep? These tiny mammals hibernate in burrows and dens. During the winter, they sleep in their nests during estivation. If you know the right time of the year to visit the burrows, you can also see them on a snowy day. But, what exactly happens during the day? Are they active during the daytime?

Ground squirrels hibernate in their burrows
During the cold months, ground squirrels hide in their burrows and keep their body temperature steady. However, in warmer climates, ground squirrels use their burrows as a sort of shade, entering and exiting them to keep their body temperature consistent. They are often less active during the day. The best time to bait your ground squirrel population is after the entire population has risen to full activity.
Young males and females start to emerge from their dens in late April or early May. The male ground squirrel is usually the first to come out of hibernation. They stay close to their burrows until the snow melts. By the beginning of June, male ground squirrels begin to breed and raise a litter of five to ten young. After hibernating, young ground squirrels develop quickly, and by late spring or early summer, they begin to leave their burrows.
They sleep during the night
During winter, ground squirrels spend most of their time hibernating, but some of them come out of their burrows earlier and don’t become active until late February or March. In general, male ground squirrels come out of hibernation earlier than females, around 10-14 days earlier. While the females sleep most of the day, they spend the summer running around and gathering food. While this isn’t the reason that ground squirrels sleep during the day, it does explain why they don’t spend the majority of the night sleeping in the burrows of other species.
In general, ground squirrels sleep between twelve and fifteen hours a day, but there are some exceptions. During the winter, ground squirrels hibernate by going into burrows and drastically lowering their metabolic processes. These animals may sleep for up to five months at a time, while remaining awake for just twelve to twenty hours a day. However, if you are trying to attract these animals to your property, make sure to provide them with a safe place to sleep.
They sleep in their dens
Ground squirrels make their dens underground. These burrows can range from 15 to 30 feet long, and are often located in a hollow, attic, or barn. They use the same hole for multiple dens, but they may share one. When there are young, they tend to sleep together in the same den for warmth. During winter, they often leave their burrows and live in trees. Ground squirrels also sleep in their dens underground.
Squirrels don’t always need to sleep in the same den. Many of them sleep in the same den as another species, so their dens can be close together. You can see them resting on their bodies by looking for their distinctive bushy tails. This tail covers the entire body, and it almost doubles as a soft blanket for them. During the day, they blink their eyes in order to avoid debris.
They sleep in their nests during estivation
Squirrels, which sleep during the hottest months of the year, engage in a process known as estivation. This period helps them to accumulate body fat and survive hot, dry conditions. Many species sleep in their nests during estivation, including flying squirrels and tree squirrels. Flying squirrels build nests inside the hollows of tree branches, drays, or even find old woodpecker holes and cavities.
Animals often hibernate to protect themselves from hot weather, which causes them to lose energy and experience a state of torpor. This process is similar to hibernation, though it lasts a much shorter time. Many animals, such as salamanders and snails, hibernate to conserve energy and fight off environmental stresses. In arid areas, arid climates, land turtles and water turtles will dig nests of loose soil and leaf matter and bury themselves in muddy creek banks to conserve moisture. When cooling rains arrive, they resume their normal lives.
They sleep in their dens during parturition
Female ground squirrels sleep in their subterranean chamber during parturition. 85% of females begin sleeping in the future parturition site in the middle or late stages of pregnancy, while the remaining 25% slept there for at least 15 nights. Two females stayed in the future parturition chamber the entire time, while the rest slept elsewhere. Despite this unusual behavior, it is not understood why females choose to sleep in their dens during parturition.
Adult female Richardson’s ground squirrels spend 35 to 37 weeks hibernating alone. Most of this time is spent in torpor, a state of a semi-dormant state that is characterized by a high degree of risk. Therefore, it is preferable to avoid disturbing the hibernaculum during parturition. Moreover, sleeping in the den limits the risk of odors and contamination of bedding.
