Squirrels are fascinating creatures that many people enjoy watching in their backyards. You might wonder, do squirrels get cold? The answer is yes, squirrels can get cold, but they have some clever ways to keep warm in colder weather. These furry animals adapt to their environment, storing fat and finding shelter to survive chilly temperatures.
In winter, tree squirrels often sleep more in their nests, while ground squirrels may hibernate in burrows. They also rely on their body fat to provide energy and warmth when food becomes scarce. Understanding how squirrels deal with the cold can help you appreciate these animals even more.
As you read on, you’ll discover more about how squirrels stay warm, the impact of extreme cold on them, and what you can do to help them during the winter months.
Understanding Squirrels and Cold Weather

Squirrels have developed various strategies to cope with cold weather. These strategies include specific behaviors that differ by species as well as physical adaptations that help them stay warm and survive through winter.
Species-Specific Winter Behaviors
Different squirrel species have unique ways of handling winter conditions. Tree squirrels, like gray and red squirrels, do not hibernate. Instead, they rely on their food stores. They gather nuts and seeds in the fall, which they bury to access when food is scarce.
Ground squirrels, such as the 13-lined ground squirrel and arctic ground squirrel, take a different approach. These squirrels enter a state called torpor, which is a form of hibernation. During this time, they lower their body temperature and metabolism, allowing them to conserve energy while staying underground.
Some species, like flying squirrels, may also spend more time in nests with family or friends, ensuring warmth through sharing body heat. These behaviors are vital for their winter survival.
Physical Adaptations for Winter
Squirrels have evolved physical traits that help them survive in cold weather. For instance, many squirrels grow thicker fur during winter months. This fur acts as insulation, keeping body heat from escaping.
In addition, squirrels accumulate extra body fat in the fall. This fat not only provides energy during food shortages but also adds an extra layer of insulation. For example, some ground squirrels create nests 2-6 feet underground, where temperatures remain more stable and warmer compared to above ground.
These physiological changes allow squirrels to maintain their body temperature. When conditions worsen, their bodies work efficiently to cope with the cold, helping them endure the harsh winter months.
Squirrel Habitats and Behavioral Strategies
Squirrels have unique habitats and clever strategies to stay warm during cold weather. They find various shelters and use their foraging skills to prepare for winter. Understanding these behaviors helps appreciate how they survive freezing temperatures.
Nesting and Shelter Against the Cold
Squirrels build cozy nests called dreys, made from leaves and twigs. These nests are often located high in trees, providing safety from predators. In winter, squirrels may also use tree cavities or share a den for extra warmth.
Their fur acts as natural insulation, keeping body heat close during chilly days. Squirrels can bulk up with an extra thick layer of fat, which builds their fat reserves. This insulation helps them stay warm when the temperatures drop.
In addition to outdoor nests, squirrels know how to find shelter in underground burrows. These spaces help protect them from harsh weather and offer additional warmth when needed.
Foraging and Food Storage
Foraging is essential for squirrels, especially when preparing for winter. They gather nuts, seeds, and tree buds from various food sources. Common finds include acorns, walnuts, and hickory nuts.
To keep enough food for the cold months, squirrels use a technique called scatter hoarding. They bury or hide food in multiple locations. This helps them avoid detection from other animals and reduces the chances of losing all their food stores.
Their high metabolic rate means they need to eat regularly. By having a well-planned food reserve, squirrels can thrive even during freezing weather. This ability to store food gives them a better chance of surviving the winter months.
