Do Squirrels Hibernate? The Surprising Answer!

If you’ve ever watched a lazy grey squirrel sit atop a tree, you likely wondered if they hibernate throughout the chilly winter season like many animals in cold climates. While it’s natural to assume so, the answer may surprise you: some do and some don’t! In this post, we’ll explore why different squirrels embark on separate paths each winter by discussing their habitats and behaviours during colder months. After reading this article, not only will you know the answer to whether squirrels hibernate or not. But also understand more about these curious creatures that we often see around us daily.

Do Squirrels Hibernate?

Do squirrels hibernate? It’s a question that has puzzled animal lovers for ages. The answer is “It depends”. While some species of squirrel do plan ahead and go into a deep sleep during colder months, others stay active all year round. This means that one species of squirrel may be snoozing through the winter while another stays out running, gathering food, and playing games like chasing each other up trees. When deciding whether or not a particular species of squirrel hibernates, the best bet is to do your research; it may surprise you!

How Long Do Squirrels Hibernate For?

Although do squirrels hibernate is a question with an answer most people may not know. The truth is that many species of squirrel do indeed enter periods of inactivity, otherwise known as hibernation. Depending on the particular species and the habitat they live in. Some have been observed to hibernate for up to nine months of the year. While others do not hibernate and instead remain active throughout winter.

During their period of deep sleep, a squirrel’s heart rate and body temperature will significantly drop. While they remain hidden away in a den or burrow beneath the ground. Squirrels do not really progress through a true hibernation like other animals do where their bodies shut down completely. But instead, basically, stay dormant until the weather warms up or food becomes more available.

What Do Squirrels Do During Hibernation?

Have you ever been out in a meadow, or somewhere with lots of trees and noticed those small, furry creatures darting around? Those are squirrels. They may seem like they never rest, but do you know do they actually do during hibernation season? It’s true that squirrels do sleep during the colder months in order to conserve energy.

The main difference is that during regular sleep, marmots wake up every few hours whereas, with hibernation, they can sleep for days. Hibernation gives them time to rest and take advantage of food sources when conditions become favourable.

Furthermore, hibernation allows them to store the extra fat from their summer foraging for leaner times ahead. So next time you see a squirrel darting around, keep in mind the hidden efforts behind its energy-saving strategies.

Do All Species of Squirrels Hibernate?

While many people may assume the answer to do all species of squirrels hibernate is a resounding yes, the reality is that not all do. In temperate climates where food availability can decrease significantly in winter. Some species may do limited hibernation or enter into a state of torpor, which is similar to hibernation but may occur more frequently.

Other squirrel species live in regions with milder winters and do not enter into a prolonged period of dormancy at all – instead. They rely on energy conservation techniques like searching out food caches that they have stored away during the summer months. Thus it can be seen that while many squirrels do hibernate some do not. It really depends on their habitat and climate.

How Does The Environment Affect a Squirrel’s Hibernation Period?

One of the most interesting characteristics of squirrels is that they do in fact hibernate during the winter months. In some regions, this may mean that squirrels remain inactive for several months depending on their environment and temperature.

The colder the temperatures are and the shorter the days become, the longer a squirrel’s hibernation period may be. Moreover, air temperature affects how much energy a squirrel can save by entering into a deeply dormant state. Warm temperatures require more energy to keep the body warm than cold temperatures.

Additionally, different species of tree squirrels have various lifestyles which can also affect how long a hibernation period lasts.

Therefore, the environment plays a critical role in enabling tree squirrels to successfully make it through winter with stored reserves of energy.


All in all, squirrel hibernation is truly a fascinating topic that can vary and depend on many different factors. Even within the same species, some squirrels may decide to hibernate while others may not due to variations in climates and living conditions. Likewise, it is interesting to note that squirrels can respond quickly to changes in temperatures over short periods of time. While more research is needed to understand what causes some squirrels to enter a state of torpor while others remain highly active all year round. One thing is certain: looking further into this process will help us gain a deeper understanding of how our environment is linked with animals’ behaviour.
