Interesting Facts about Squirrels

Squirrels are very interesting animals. You can find them everywhere in the world. I grew up in Switzerland and we had squirrels there too. They are not as common as they are here in eastern Canada. In Switzerland, you mainly find the common dark brown squirrels.

As kids, our parents used to take us to the mountains where we spent 2 weeks of our summer holidays. In those days we frequently saw marmots. They have a very interesting security system. One marmot is responsible for watching for danger while the others eat or play around. As soon as there is danger, the marmot keeping watch whistles and they all disappear in their burrows.

We live in the countryside, and we see many different squirrels. I always wanted to know more about them, especially the grey, black and red squirrels and the chipmunks.

I thoroughly enjoyed researching and writing this blog post. Here is what I came up with.

General InformationRed Squirrel

  • The squirrels are rodents.
  • Rabbits, squirrels & other rodents have teeth that never stop growing. They have to chew on tough foods, like nuts, leaves, and bark, to wear them down.
  • They are members of the Sciuridae family.
  • A group of squirrels is called scurry or dray.

Good to know

Life Span

  • The eastern grey squirrel could live about 4 years. however it typically only lives up to 18 months due to diseases, human interactions, and predators.
  • The American red squirrel can live up to eight years. They have a high mortality rate under the age of 3 years old.
  • The mountain marmot lives between 15 and 18 years
  • And the Siberian chipmunk even gets up to 28 – 35 years old.


  • The African pygmy squirrel only weights 16 g
  • Siberian chipmunk  comes in a bit heavier at 50-150 grams
  • The Eastern grey squirrel averages 400-600 grams
  • The heaviest of them all is the Alpine marmot at 2.8-3.3 kg

Gestation Period

  • Squirrel 44 days
  • Alpine marmot 33-34 days
  • Siberian chipmunk 28-35 days


  • Young ones are usually born between March and April, with a second litter arriving around July to August.
  • Females give birth to 1-9 babies, though somewhere in the range of 3-5 is typical.
  • Each baby is completely dependent on its mother for the first five to eight weeks of its development and stays close to the nest during this time.
  • During the birthing season, squirrels move closer to human homes and sometimes take residence behind walls, in attics, sheds, and chimneys.
  • After weaning, the young ones venture out with their mother to find more natural shelters.
  • It is important not to block holes during that time, even if the humans find the babies inside.


The squirrel has many predators. Because they are small rodents, some of them are:

  • Red and grey fox
  • Owls, hawks, eagles, and various other birds
  • Snakes
  • Pine martins, raccoons, coyotes, and bobcats
  • Wild and domestic cats
  • Dogs
