Squirrels are small rodents that are common in many parts of the world– despite their size, they can have a profound impact on their environment

In addition to their normal behaviors such as foraging for food, building nests, and storing acorns, they are one of the few rodents that enter a state of dormancy known as hibernation. In this article, we’ll discuss the basics of hibernation in squirrels, when and why they enter this state, and the potential implications of it.

What is Hibernation?

Hibernation is an act of dormancy in which an animal undergoes drastic changes in their metabolic activities, adapting to the changing environment and temperatures. During this period, their metabolic rate considerably slows down and their heartbeat also becomes very slow and weak. With these changes, the animal uses less energy and does not have to feed as often. Most mammals and reptiles that hibernate come out of it healthy and well-rested.

Why do Squirrels Hibernate? 

The primary reason why squirrels enter the state of hibernation is due to the changing temperatures. Most squirrels are accustomed to living in climates where temperatures can drop drastically during the winter, and though they often have ample food sources nearby, some species will enter into hibernation as a means of conserving energy.

Other reasons for hibernation in squirrels can often depend on the species, with some hibernating just because there is less food available during certain times of the year, while others may enter a “light” state of hibernation after they have reached a certain age.

When Do Squirrels Hibernate? 

The period in which squirrels enter into hibernation can differ depending upon the species and the climate, though it typically occurs in late fall or early winter. Generally, the period when squirrels are most likely to hibernate is during the coldest parts of the winter.

The Signs of Hibernation in Squirrels
There are a few key signs that a squirrel may be preparing to enter a state of hibernation, including the following:

• They eating far more food than usual in order to store up energy
• Excessively and continually storing food in their nests
• Spending more time in their nests, especially passing up opportunities to forage
• Becoming less active and spending more time in sheltered habitats
• Spending more time slowly running along branches and tree trunks rather than bounding from branch to branch

Effects of Hibernation 

Hibernation in squirrels can have both positive and negative effects. The main positive effect is that it helps the squirrels conserve energy and survive during the coldest parts of the winter. This is particularly essential for species that are less adapted to extreme temperatures, such as in the northern parts of North America.

However, hibernation can also be a dangerous state for squirrels. For example, if the temperature drops too far outside of the squirrel’s hibernation period, they will not be able to find food, and they may starve. Additionally, if the hibernation period lasts too long, the body can experience a significant decrease in muscle tone and bone density.

How to Help Prevent Hibernation? 

There are a few tips and tricks for helping prevent unnecessary or extended hibernation in squirrels.

• Providing food sources such as bird feeders and fruit trees throughout the winter can help ensure the squirrels don’t have to store up too much energy in anticipation of hibernation.
• Planting trees or shrubs that provide natural habitat and protection during winter can provide a safe spot for squirrels to hide and reduce hibernation.
• Building shelters or boxes can help to keep the squirrels warm during cold nights without entering hibernation mode.

Hibernation in squirrels is a complex process, with multiple factors playing a role in the decision. It’s important to take steps to ensure that the squirrels don’t enter a prolonged state of hibernation as this can lead to long-term health issues as well as disruption in the ecology of the area. By planting trees, providing plentiful food sources, and building suitable shelter, we can help protect squirrels from unnecessary hibernation.
