We all know that squirrels spend the winter in burrows, tunnels and food caches. But how do they survive the cold temperatures? There are three main ways they cope with cold temperatures: By sharing a nest and staying close to each other, they generate body heat by shivering. A melanistic black grey squirrel has a major advantage when it comes to body warmth. Read on to find out how squirrels survive the winter.

Food caches

The process of hiding food and using memory is known as “caching.” This behavior enables the squirrels to retrieve the food that they need in a short amount of time. These stores are known as food caches. The number of food caches differs according to the mast crop. Typically, mature squirrels hide thousands of nuts throughout the year. Because they can’t keep track of all of these caches at once, other animals can take advantage of them and take away up to 25 percent of the food that they’ve cached.

These stores are strategically located. Many squirrels create food caches underground, a practice known as hoarding. They use shallow holes to store nuts and seeds that they collect throughout the year. They also group together to create communal hoards. Squirrels also forage on birds’ eggs, animal bones, and mushrooms. This way, they can store fat and stay warm throughout the Oakville winter.


Ground squirrels spend six months of the year inactive in their burrows. While this isn’t an alarming trait, it isn’t exactly a pleasant one. It means less work for you, but it also means less damage to your lawn. Ground squirrels burrow into lawns and gardens, causing damage to plants. While ground squirrels can squeeze through a hole as small as one-half inch, you need to consider the danger this poses to your property.

Squirrels have a variety of methods for surviving the winter months, including increasing their fat reserves in the autumn and finding suitable burrows. Their burrows are usually underground, but they will occasionally come out to consume food cached earlier in the year. To stay warm, squirrels will either eat food cached earlier in the winter, or make new burrows. They may also change their fur to store more heat.


If you want to learn how squirrels survive the winter, you should learn about their winter home. In a snow-covered yard, you can find a squirrel in a tunnel. The animals live in tunnels during the winter to conserve energy. During the summer, they leave their burrows to feed and hide from predators. However, during the winter, they remain active and make use of the burrows to find food and rest.

These tiny creatures live in the subnivean zone. This is an opening under the snow that is home to many small mammals. The ground temperature is around 32 degrees Fahrenheit in this area, making it ideal for the animals to survive the winter. They also build complete underground quarters and reproduce any time of the year. The animals’ main predators are weasels, which are able to hunt them in their burrows.


While most mammals can stay in torpor for the entire winter, squirrels can only do so for about 20 days at a time. They must wake up from their winter hibernation every 20 days to rewarm themselves to their normal mammalian body temperature of 37 to 40 C. While in torpor, they cannot run or fight off predators, and they must use the time to build up fat reserves and rebuild their body heat. In addition to using this time to rest, squirrels will also seal the entrance to their hibernaculum with dirt.

Scientists are studying how skeletal muscle breaks down during hibernation, and this process releases nitrogen compounds that are vital for the production of muscle proteins. Since squirrels maintain muscle mass while hibernating, it is unknown whether they also build up new protein stores during this time. To learn how squirrels do this, scientists are studying ground squirrels in the Arctic region. These animals lose enormous amounts of neurons during hibernation, but when they wake up, they rewire those connections. This study could eventually lead to treatments for degenerative brain diseases in humans.

How do squirrels prepare for winter?

Answer: By stocking up on food and storing it in their nests or dens.

How much food do squirrels need to store?

Answer: They need to store enough food to last them the entire winter.

Where do squirrels find food during the winter?

Answer: If they are lucky they are able to find food that they have stored.

However if they can’t find their food they will have to look for food sources.

How do squirrels keep warm during the winter?

Answer: By keeping their nests or dens well insulated.

Do all squirrels hibernate during the winter?

Answer: No not all squirrels hibernate.

What is the difference between hibernation and torpor?

Answer: Hibernation is a prolonged state of inactivity in which an animal’s metabolism slows down and they can survive on stored energy.

Torpor is a brief state of inactivity in which an animal’s metabolism slows down.

How do squirrels survive if they don’t hibernate or store enough food?

Answer: If they can’t find food they will slowly starve to death.

What are some of the predators of squirrels?

Answer: Owls hawks snakes and foxes are some of the predators of squirrels.

How do squirrels avoid being eaten by predators?

Answer: By being very alert and by being quick to run up a tree or into their nests.

What happens to squirrels if they get too cold?

Answer: If they get too cold they will die.

What happens to squirrels if they get too hot?

Answer: If they get too hot they will die.

What are some common diseases of squirrels?

Answer: Some common diseases of squirrels include mange rabies and distemper.

How do squirrels usually die?

Answer: Most squirrels die of old age starvation or predators.

What is the life span of a squirrel?

Answer: The life span of a squirrel is usually about 5 years but some can live up to 10 years.

Do baby squirrels have a better chance of surviving than adults?

Answer: No baby squirrels have about the same chance of surviving as adults.
