Join us on a journey as we uncover the intricate details of where, when, and how squirrels rest, shedding light on their nocturnal routines and evolutionary adaptations.

Where Do Squirrels Sleep?

Squirrels are master architects when it comes to crafting their sleeping abodes. These cozy nests, known as dreys, are meticulously constructed from twigs, leaves, and other natural materials. Positioned high in the branches of trees, dreys offer squirrels protection from predators and the elements, creating a haven where they can rest undisturbed.

Types of Squirrel Nests

Squirrels are ingenious nest builders, using different types of structures depending on the species, environmental conditions, and time of year. Here are the primary types of squirrel nests you might come across:

  1. Dreys: The most common type of squirrel nest, dreys are typically found high in the branches of trees. They are made from twigs, leaves, and bark, and lined with softer materials like moss, feathers, or fur. Dreys are usually spherical and have one or more entrance holes. Squirrels often build several dreys within their territory for shelter and to escape predators.
  2. Tree Cavities: These natural or woodpecker-made holes in trees provide excellent protection from the elements and predators. Tree cavities are preferred especially in winter because they offer better insulation than dreys. Squirrels line the interior with grass, leaves, and fur to make them cozy and warm.
  3. Ground Nests: Although less common, some ground-dwelling squirrels build nests underground. These nests, similar to burrows, provide excellent protection and are primarily used by species like the ground squirrel. They consist of complex tunnel systems with multiple entrances and can also be used for storing food.
  4. Nest Boxes: In areas where natural nesting sites are scarce, squirrels may use nest boxes if they are available. These are man-made alternatives that mimic the safety of tree cavities and are sometimes used in squirrel rehabilitation or conservation efforts.

Each type of nest serves a specific purpose, whether for rearing young, staying warm, or evading predators, highlighting the adaptability and resourcefulness of squirrels in various environments.

Squirrels Sleep Location

Squirrels sleep in a variety of locations depending on their species and habitat. Here are some common places where squirrels are known to rest:

  1. Tree Nests (Dreys): Most squirrels build nests, called dreys, in the branches of trees. These nests are typically constructed from twigs, leaves, and other natural materials, providing shelter and protection from the elements.
  2. Tree Cavities: Some squirrels, such as the Eastern gray squirrel, may seek refuge in natural or woodpecker-made holes in trees. These cavities offer excellent protection from predators and harsh weather conditions.
  3. Underground Burrows: Ground-dwelling squirrels, like ground squirrels, construct elaborate burrow systems underground. These burrows provide insulation and safety from predators, as well as a place to raise their young.
  4. Nest Boxes: In urban or suburban areas where natural nesting sites are limited, squirrels may utilize man-made nest boxes placed in trees or on poles. These boxes provide a secure alternative to natural nesting locations.
  5. Dense Vegetation: Squirrels may also sleep nestled in dense foliage or shrubbery, particularly during warmer months when tree nests may be too hot or exposed.

Regardless of the location, squirrels choose sleeping spots that offer protection from predators, shelter from the elements, and a sense of security, ensuring they can rest undisturbed and recharge for their next active period.

Seasonal Changes Squirrels’ Sleeping Habits

Squirrels’ sleeping habits can vary significantly with seasonal changes, largely due to variations in temperature and the availability of food. Here’s how these factors influence squirrel behavior throughout the year:


In spring, as temperatures rise and food becomes more plentiful, squirrels are very active. They spend less time sleeping during the day and are more frequently seen foraging and rebuilding or repairing their nests. This season is also mating season for many squirrel species, which increases their activity levels even further.


During the hot summer months, squirrels may adopt a pattern of resting during the hottest part of the day to avoid excessive heat and dehydration. They are typically active during the cooler hours of the morning and late afternoon. In regions with particularly hot climates, squirrels might exhibit more crepuscular (active at twilight) behaviors to cope with the temperature extremes.


Autumn is a critical time for squirrels as they prepare for winter. They are highly active, gathering and storing food for the cold months ahead. During this season, you might notice squirrels are active for longer periods throughout the day, reducing their sleep hours to maximize food collection and nest preparation.


In winter, many squirrel species sleep more due to the colder temperatures and reduced food availability. They may enter a state of torpor, a light hibernation-like state where their body temperature, heart rate, and respiratory rate lower to conserve energy. Squirrels tend to stay in their nests longer during the cold weather, venturing out primarily during warmer parts of the day to forage.

Overall, the changes in squirrels’ sleeping habits are primarily driven by environmental cues and survival strategies adapted to their specific habitat and climate. These seasonal behaviors ensure they maintain the energy needed for their active and often visible daytime period.

Sleep effects in urban environment squirrels

Urban environments significantly influence the sleeping habits and overall behavior of squirrels. These changes arise due to differences in food availability, human interaction, and habitat structure compared to their natural, more rural settings. Here’s how an urban setting might affect squirrels’ sleep:

1. Increased Light Pollution

Urban areas are often much brighter at night due to street lights, vehicle headlights, and other sources of artificial lighting. This light pollution can disrupt the natural sleep cycles of squirrels, potentially leading to altered patterns of activity. Squirrels may become more nocturnal in urban settings, changing their active and resting periods.

2. Temperature Variations

Cities tend to be warmer than rural areas due to the heat island effect, where buildings, roads, and human activities increase the ambient temperature. Warmer temperatures can affect the periods when squirrels are active, often leading to more nighttime activity to avoid the daytime heat.

3. Noise Disturbances

Urban noise can also disrupt squirrel behavior. Constant urban noise from traffic, construction, and human activity can lead to heightened stress levels in squirrels, potentially affecting their sleep quality and duration.

4. Availability of Food Resources

Urban areas often provide abundant food sources for squirrels, such as garbage bins, bird feeders, and food scraps. This easy access to food can change their natural foraging behaviors and reduce the need for prolonged activity periods, thus altering their sleep patterns. Urban squirrels might not need to spend as much time foraging due to readily available food, which could lead to more time resting or engaging in other behaviors.

5. Predation and Safety

The reduced presence of natural predators in urban areas might allow squirrels to feel safer, thereby affecting where and when they choose to sleep. However, urban threats like cars and domestic pets can also alter their behavior, making them more cautious and potentially affecting their normal rest periods.

Overall, the urban environment presents numerous challenges for squirrels, including disturbances to their sleep patterns. Mitigating these effects through habitat conservation, noise reduction measures, and public awareness can help promote healthier sleep habits for urban squirrels.

When Do Squirrels Sleep?

Squirrels are primarily diurnal creatures, meaning they are most active during the day. However, their sleeping patterns can vary depending on factors such as food availability, environmental conditions, and the presence of predators. In quieter, less disturbed areas, squirrels maintain a more consistent sleep-wake cycle, while in urban settings, they may adjust their activity patterns to avoid human disturbances.

How Do Squirrels Sleep?

When it’s time to settle down for the night, squirrels curl up into a tight ball within their dreys, using their fluffy tails as makeshift blankets to ward off the cold. They may also tuck their heads under their tails or limbs, adopting a compact posture that maximizes warmth and minimizes exposure to potential threats.

Baby Squirrels Sleep

Baby squirrels, much like human infants, require a lot of sleep to support their rapid development and growth. When they are very young, they might spend up to 20 hours a day sleeping. This extensive amount of sleep is vital for their physical maturation, immune system strength, and the development of neurological pathways.

Nestled in their nests, typically made from leaves and branches and often located in the forks of trees, baby squirrels are generally born in litters of two to five. These nests serve not only as a home but also as a safe haven where they can rest undisturbed. The warmth and comfort of the nest, combined with the closeness to their mother and siblings, create an ideal sleeping environment.

During their sleep, baby squirrels are mostly motionless, which is crucial for their safety, keeping them hidden from predators. Their sleep is deep, facilitating the essential bodily functions that contribute to healthy growth. As they get older, the amount of sleep they need gradually decreases, and they become more active, exploring their surroundings and learning the skills necessary to survive in the wild.

Overall, the extensive sleep that baby squirrels indulge in is a fundamental aspect of their early life, crucial for their development into healthy adult squirrels.

Do Squirrels Dream While They Sleep?

Yes, squirrels do dream while they sleep. Like many other mammals, squirrels experience REM (Rapid Eye Movement) sleep, which is the phase of sleep associated with dreaming. During REM sleep, a squirrel’s brain activity increases, similar to what happens in the human brain during dreaming. This suggests that squirrels, like humans and many other creatures, likely have dreams that could involve scenarios related to their daily activities, such as foraging or escaping from predators. The function of dreaming in squirrels isn’t fully understood, but it might play a role in processing memories and learning, similar to what has been hypothesized in other animals.

Squirrels’ Safety in Sleep

Squirrels are always alert, Even in sleep, squirrels remain vigilant, ready to spring into action at the slightest sign of danger. Their choice of sleeping location is carefully selected to ensure quick escape routes and optimal vantage points, allowing them to evade predators and other potential threats. With squirrels spending a significant portion of their day asleep, it’s crucial to understand the potential risks they face and how to mitigate them. This comprehensive guide covers various aspects, including identifying safe sleeping spots, creating squirrel-friendly environments, and safeguarding against common threats such as predators and harsh weather conditions.

Discover practical tips for homeowners and nature enthusiasts to promote squirrel safety, such as providing secure nesting options, avoiding harmful chemicals in landscaping, and implementing deterrents for potential predators. By following these recommendations, individuals can play a vital role in protecting squirrel populations and fostering a harmonious coexistence between humans and wildlife.

Can squirrels sleep together?

It’s common for mother squirrels to sleep snuggled up with their babies. However, outside of breeding seasons, most adult squirrels prefer to sleep alone to maintain their territory.

When squirrels sleep together, it’s primarily a behavior observed in colder climates where staying warm is essential for survival. This communal sleeping, known as “nest cohabitation,” involves multiple squirrels sharing a nest to conserve body heat during the cold winter months. Squirrels build their nests, called “dreys,” out of leaves and twigs, often in the forks of trees. These nests are usually well-insulated, but the added body heat from multiple squirrels can make a significant difference in survival rates.

While many species of squirrels are solitary for much of the year, social sleeping arrangements are more common during the winter. It’s also more frequently observed in young squirrels who may stay with their siblings and mother while they are still dependent. Apart from warmth, sleeping together can offer additional protection against predators, as there are more individuals alert to potential threats upon waking.


The sleeping habits of squirrels are a testament to their remarkable adaptability and survival instincts. Whether nestled high in the treetops or nestled within the confines of a cozy attic, squirrels have perfected the art of finding rest in even the most challenging of environments.

By delving into the intricacies of squirrel sleep behavior, we gain a deeper appreciation for these resilient and resourceful creatures, marveling at their ability to thrive in the ever-changing landscapes of our world.

This comprehensive guide not only provides valuable insights into the sleeping habits of squirrels but also serves as a reminder of the importance of coexisting harmoniously with the diverse array of wildlife that surrounds us.
