Types of Squirrel Sleeping Habits

Squirrels are known for their playful and lively nature, but they also have unique sleeping habits. In this section, we will discuss the various types of squirrel sleeping habits.

Tree Nesting

Tree nesting is a common sleeping habit of squirrels. They often build their nests in tree cavities or construct them by weaving twigs and leaves high up in the branches of trees. Tree nesting provides a secure and elevated location away from predators and other threats.

Squirrels build their nests in different shapes and sizes depending on the species and location. Some nests are spherical, while others are flattened, and some are even shaped like a bottle. They also use different materials such as leaves, twigs, moss, and bark.

Ground Nesting

Ground nesting is another common sleeping habit of squirrels. They dig burrows in the ground, which serves as their shelter and resting place. Ground nesting provides a safe and insulated location, especially during cold weather.

Squirrels usually dig their burrows in soft soil or under tree roots. They also create multiple entrances and exits to avoid being trapped inside and to provide an escape route when needed.


Denning is a sleeping habit of squirrels that involves taking shelter in natural or human-made structures. Squirrels may use hollow logs, rock crevices, or even attics and chimneys as their den. Denning provides a secure location that protects squirrels from predators and other dangers.

Squirrels may also use human-made structures such as birdhouses or abandoned buildings as their den. These structures provide an excellent alternative to natural shelters, especially in urban areas where natural habitats are scarce.

Factors Affecting Squirrel Sleeping Habits

Squirrels are known to be adaptable creatures, and their sleeping habits are no exception. Their sleeping habits are affected by various factors such as temperature, predators, and food availability. In this section, we will delve into each of these factors and how they affect the sleeping habits of squirrels.


Temperature is one of the most significant factors affecting squirrel sleeping habits. Squirrels are known to be active during the day and sleep at night, but during extreme weather conditions, they may alter their sleeping patterns. For instance, during hot summer days, squirrels may take naps during the day and remain active during the cooler nights. In contrast, during winter months, they may sleep for longer hours to conserve energy and stay warm.


Predators can also influence squirrel sleeping habits. Squirrels are preyed upon by a variety of animals, including hawks, owls, and snakes. To avoid being preyed upon, squirrels sleep in safe and secure locations, such as tree cavities or underground burrows. They may also sleep in groups to increase their chances of survival. When predators are present, squirrels may sleep less and remain alert to avoid being caught off guard.

Food Availability

Food availability is another crucial factor affecting squirrel sleeping habits. Squirrels need to eat frequently to maintain their energy levels, and they may adjust their sleeping patterns based on food availability. For instance, during periods of food scarcity, squirrels may sleep for longer hours to conserve energy. Conversely, when food is abundant, they may sleep less and spend more time foraging.

Daily Sleep Patterns of Squirrels

Squirrels are known to be active during the day, but they also engage in various sleep patterns. Understanding a squirrel’s daily sleep patterns can help us appreciate their behavior and habitat better. Here are some interesting facts about a squirrel’s daily sleep patterns:

Diurnal vs. Nocturnal

Squirrels are diurnal animals, meaning they are active during the day and sleep at night. During the day, they spend most of their time foraging for food and socializing with other squirrels. When night falls, they retreat to their nests to sleep. However, some species of squirrels, like the flying squirrel, are nocturnal. They are active at night and sleep during the day.

Sleep Duration

Squirrels usually sleep for short periods throughout the day, totaling up to 14 hours in a 24-hour cycle. They take naps that last between 15 minutes to an hour or more. During these naps, they may appear motionless or curled up in their nests.

Sleep Interruptions

Squirrels are light sleepers and can easily be awakened by loud noises or disturbances. They may wake up to check their surroundings for potential predators or other threats. When they feel safe, they go back to sleep. This means that squirrels may have multiple sleep interruptions throughout the day, which could affect their energy levels and overall health.

To summarize, squirrels are diurnal animals that sleep for short periods throughout the day. They take naps that last between 15 minutes to an hour or more and are easily awakened by disturbances. Understanding a squirrel’s daily sleep patterns can help us appreciate and protect these fascinating creatures.

Seasonal Changes in Squirrel Sleeping Habits

Squirrels are known for their energetic and agile nature. However, during certain times of the year, their sleeping habits change drastically. Here, we will discuss the seasonal changes in squirrel sleeping habits, including hibernation, torpor, and winter nesting behaviors.


During winter, when the temperature drops, squirrels undergo a state of hibernation. Hibernation is a deep sleep state that helps them conserve energy and survive through the harsh winter conditions. During hibernation, the squirrel’s heart rate and breathing slow down significantly, and their body temperature drops. They do not eat, drink or excrete waste during this period.


Torpor is a temporary state of reduced activity and metabolism that some squirrels undergo during winter. This state helps them conserve energy and survive when food is scarce. Unlike hibernation, torpor is not as deep, and squirrels can wake up and forage for food if necessary. They may enter torpor for a few hours or days, depending on the availability of food.

Winter Nesting Behaviors

During winter, squirrels also change their nesting behaviors to adapt to the cold weather. They may build larger and more insulated nests, using materials such as leaves, twigs, and moss. They may also burrow into the ground or use natural cavities in trees to stay warm. Some squirrels may even share their nests with others to conserve body heat.

Sleeping Habits of Urban Squirrels

Urban environments present unique challenges for squirrels, but they have proven to be highly adaptable creatures. In this section, we will explore the sleeping habits of urban squirrels and how they have adapted to their new surroundings.

Adaptation to Urban Environments

Squirrels have been able to adapt to urban environments by finding new food sources, nesting locations, and avoiding predators. In urban areas, squirrels may feed on bird feeders, gardens, and even trash cans. They have also been known to nest in attics, buildings, and even inside cars.

Sleeping in Attics and Buildings

One of the most common places for urban squirrels to sleep is in attics and buildings. They may enter through small holes or gaps in the roof, walls, or foundation. Once inside, they will typically build a nest using materials like leaves, twigs, and debris. Squirrels will often sleep during the day and be active at night, using attics and buildings as a safe place to rest.

Sleeping on Power Lines

Squirrels have also been known to sleep on power lines. While it may seem dangerous, squirrels have a unique ability to balance and grip onto objects. They can use their tails to help them balance and move along the power lines. Power lines provide a safe place for squirrels to sleep, away from predators and ground-level dangers.

Overall, urban environments have presented new challenges for squirrels, but they have been able to adapt and thrive in these environments. Whether it’s nesting in attics or sleeping on power lines, squirrels have found ways to make these new environments their own.

Sleeping Habits of Squirrels in Captivity

Squirrels are known for their playful and energetic nature, but what happens when they are taken out of their natural habitat and placed in captivity? In this section, we will explore the sleeping habits of squirrels in captivity, including sleep deprivation, nesting materials, and sleeping in cages.

Sleep Deprivation

Sleep deprivation can have a significant impact on the health and well-being of squirrels in captivity. When squirrels are kept in cages, they may not have access to the same sleeping patterns they would have in the wild. For example, they may be exposed to artificial light, which can disrupt their circadian rhythms and prevent them from getting enough sleep.

In addition, squirrels kept in captivity may be subjected to stress, which can also affect their sleep patterns. They may be constantly on alert and unable to fully relax, which can lead to sleep deprivation and other health issues.

Nesting Materials

In the wild, squirrels create elaborate nests out of natural materials such as twigs, leaves, and moss. When they are in captivity, it is important to provide them with similar materials to create a comfortable sleeping environment. This can include providing them with nesting boxes or baskets filled with soft materials like shredded paper, hay, or even old t-shirts.

By providing squirrels with nesting materials, they are more likely to feel safe and secure in their sleeping environment. This can help them to relax and get the sleep they need to stay healthy.

Sleeping in Cages

When squirrels are kept in captivity, they are often housed in cages that are much smaller than their natural habitat. This can make it difficult for them to get the exercise they need and can also impact their sleep patterns. Squirrels may not have the space they need to fully stretch out and get comfortable, which can lead to sleep disturbances and other health issues.

To help improve their sleeping environment, it is important to provide squirrels with a cage that is large enough for them to move around in comfortably. This can help them to get the exercise they need and can also improve their sleep patterns.

Sleep-Related Behaviors of Squirrels

Squirrels are known to exhibit a variety of sleep-related behaviors that are fascinating to observe. These behaviors include sleep-twitching, snoring, and dreaming.


Sleep-twitching is a common behavior among squirrels that occurs during the REM (Rapid Eye Movement) stage of sleep. During this stage, squirrels may twitch or move their limbs as if they are running or jumping. This behavior is believed to be a result of their active lifestyle and the need to constantly be alert and aware of their surroundings.


Yes, squirrels can snore! This may come as a surprise to some, but squirrels are known to snore while they sleep. This behavior is more common in larger species of squirrels, such as the fox squirrel. Snoring is believed to be a result of the relaxation of the muscles in the throat and airways, which can cause a vibration and produce the sound of snoring.


Like humans, squirrels are believed to dream during their sleep. This has been observed through the presence of REM sleep, which is associated with dreaming. While we do not know exactly what squirrels dream about, it is possible that they dream about their daily activities, such as foraging for food or evading predators.

In conclusion, sleep-related behaviors of squirrels are not only interesting to observe but also provide insight into their active lifestyle and their ability to adapt to their environment. Whether it’s sleep-twitching, snoring, or dreaming, squirrels are fascinating creatures that continue to amaze us with their unique behaviors.
