5 Fascinating Winter Habits of Squirrels: From Nest-Building to Hibernation

The Fascinating World of Winter Animals: Understanding Squirrel Behavior and Hibernation

Winter is the season of dormancy, where nature slows down to preserve its energy. For animals, survival during this period is paramount, and they resort to various techniques to stay alive.

One such animal is the squirrel, known for its acrobatic skills and love for nuts. During winter, squirrels go through a transformation that enables them to survive harsh conditions.

In this article, well explore the world of squirrel behavior and hibernation, shedding light on what makes these creatures thrive even in the coldest times.

Burial of food supplies

One of the most intriguing behaviors of squirrels during winter is the storage of nuts and seeds. The act of burying food for the winter season is known as caching, and squirrels are remarkably good at it.

They have a keen sense of smell, which helps them locate their food after months of burying it. Squirrels also have an excellent memory, which allows them to remember the specific location of their buried treasure.

But why do squirrels store food in the first place? The answer is simple: to survive.

During winter, food is scarce, and the squirrels need to have a constant supply to avoid starvation. By storing food, they can survive for up to six months without having to venture out to look for food.

Squirrels have been observed burying nuts and seeds in several locations, from the ground to tree trunks and even in between rocks.

Survival techniques

Apart from storing food, squirrels have other survival tactics they use during winter. One such technique is nesting.

Squirrels build their nests in trees, using a combination of twigs, leaves, and moss. The nests provide warmth and comfort for the squirrels, helping them to conserve energy in the cold.

Another technique squirrels use is fattening up. They do this by consuming as much food as they can before winter sets in.

The extra weight gained builds up their fat reserves, which they use as fuel during hibernation. The more fat reserves a squirrel has, the more likely it is to survive during winter.

Hibernation in squirrels

Many people believe that all animals hibernate during winter, but this is not entirely true. In fact, only a few animals go into true hibernation.

Squirrels are not among them. Instead, they go into a state of torpor, which is a type of sleep that allows them to conserve energy while still being able to wake up and move around.

Ground squirrels, on the other hand, do go into true hibernation. During hibernation, their metabolism slows down to the point that they can survive on little or no food for several months.

This is achieved through a complex process known as HIT (Hibernation-Induced Torpor), which triggers a series of physiological changes in the squirrel’s body.

Hibernation in animals

Apart from squirrels, several other animals hibernate during winter. These include bears, woodchucks, little brown bats, jumping mice, eastern chipmunks, and poorwill birds.

Hibernation is triggered by a combination of factors, such as a decrease in food supply, a drop in temperature, and the ability to store fat reserves. During hibernation, animals experience a slowed-down metabolism, lower body temperature, and reduced heart rate.

This helps them conserve energy, thereby avoiding starvation during the winter months. Hibernation is not a one-size-fits-all approach, as each animal has its own hibernation tactics to ensure survival.


In conclusion, winter is a critical period for animals, and survival is paramount. Squirrels, like many other animals, have a range of behaviors and techniques they use to survive during this difficult season.

From caching to hibernation, these tactics enable squirrels to thrive even in the harshest winter conditions. So, the next time you see a squirrel burying nuts, or a bear entering its hibernation den, remember that these behaviors are essential for their survival and that makes them all the more fascinating.

Winter Habits of Squirrels:

Nest Building,

Food Collection, and

Fattening Up

Winter is a challenging time for many animals, including squirrels. Despite the harsh conditions, squirrels have adapted to survive through various habits.

In this article, we’ll dive deeper into the winter habits of squirrels, including their nest building, food collection, and fattening up.

Nest Building

One of the first winter habits a squirrel will engage in is building a nest. Squirrels create their nests, called dreys, using twigs, leaves, and moss.

They often build these nests in tree branches or hollows to protect themselves from cold and wind. Their nest-building habits can begin in the fall, with squirrels gathering materials and storing them in a convenient location.

When the time comes to build the nest, they’ll assemble the materials to form a cozy abode. The construction process can take several days, with squirrels working tirelessly to create a comfortable haven for themselves.

Some common materials squirrels use to build their dreys include twigs, bark, leaves, and even grass and other plant materials. While dreys are usually constructed in trees, squirrels sometimes build their nests in holes and other cavities in the ground.

Food Collection

Squirrels are active food collectors during winter, hoarding food for future use. They collect and store berries, nuts, seeds, and insects, among other things.

These food sources are critical for the squirrels’ survival, as they will sustain them throughout the winter season. Squirrels have several methods for collecting and storing food.

One technique involves scavenging, in which squirrels explore their surrounding to gather a variety of food sources. Once theyve collected enough food, squirrels will store it in a variety of locations, including tree hollows or knotholes, underground burrows, or even in cache piles on the ground.

Another method of food collection involves the burying and caching of nuts and seeds. Squirrels use their sharp sense of smell to locate their buried food during the winter months.

In some cases, so precious is their stash that they’ll even go to the extent of guarding them from other squirrels and predators.

Fattening Up

Squirrels start fattening up in the fall, consuming a surplus of food to build up their energy reserves. Squirrels gain body fat during the warmer months to sustain their energy and body heat during the winter.

This extra fat serves as an energy reserve when food sources are scarce. Fattening up is one of the critical aspects of squirrel winter habits.

The more body fat they can gain, the more likely they are to survive the winter season. They’ll continue to eat throughout the winter season, but their food sources will be gradually depleted.

Hence, it’s easy for squirrels to emerge from winter hibernation, weak and starved, which is why this activity is so essential. Spotting Squirrels During Winter: Activity,

Ideal Habitats, and

Different Habits Among Species

Spotting squirrels during winter can be challenging, given the behaviors and habitats of these creatures.

Understanding their activity patterns and ideal habitats can enhance your chances of seeing these adorable animals during the colder months.

Activity During Winter

Squirrels are mostly active during the morning and late afternoon hours of winter. This is when they leave their nests to scavenge for food and check their cache piles.

During the hottest parts of the day, its common for the squirrels to take refuge in their nests, conserving their energy and avoiding the cold. Another notable squirrel activity during winter is the building of new or repair of existing nests.

Some species are known to migrate during the winter season, with others, such as the gray and red squirrel, being year-round residents.

Ideal Habitats

Squirrels are tree-dwellers, and tree habitats are the best place to spot them during winter. Following nut-burying habits typically leads to the animal’s nest, so keep an eye out for any signs that squirrels have been active in certain areas.

These can include mounds of leaves and twigs around the base of trees, along with freshly dug holes in the ground.

Different Habits Among Species

While all squirrels share similar winter habits, there are some distinct differences in their behavior. For instance, ground squirrels go into true hibernation, slowing their metabolism and lowering their body temperature significantly.

Gray squirrels, on the other hand, remain active at all times. They tend to spend most of their winter days in a single tree, only venturing out for brief periods to harvest food.

They typically inhabit tree hollows and knotholes and are known for their resourcefulness in finding food sources amid the snow. Finally, red squirrels are known to have a robust caching habit.

They are also known for their vocalization and are sometimes referred to as the “chatterbox of the forest.” These squirrels are playful and curious, making them a joy to spot during winter.


Squirrels are fascinating creatures that have adapted to survive the harsh winter conditions through several unique habits, such as nest building, food collection, and fattening up. By understanding the behavior and ideal habitats of different squirrel species, spotting these creatures during winter becomes much easier, leading to unforgettable moments of appreciation and admiration for these clever creatures.
