In Canada, some have rufous bellies and tails. Black phase is common in northern parts of its range.

Mating, Breeding, Gestation Habits

During the mating season which is twice a year, December to January and late May to July, a type of chasing occurs.

The female gives off a scent that attracts males. A line of males can be seen chasing one female.

While this chase may seem like the female is trying to get away its really a test of the agility of the male.

The male that keeps up with her shows that he has strong genitics to pass on.

The ones immediately behind her in the chase are the most dominant males and one will likely mate with her.

Their home or nest is a leafy nest located in a cavity or fork of a tree.

Do Gray Squirrels Mate For Life?

The Female Eastern Gray chooses a male for each liter she has. The males do not help in raising or the feeding of the young.

Males will breed with multiple females during each breeding season, but neither mate for life.

Cavities suitable for squirrel nests occur most often in older trees, particularly white oaks, elms, sycamores and soft maples.

These are preferred home sites especially for winter and for nurseries, because they provide good protection from weather and enemies.

Squirrel Squawking

In summer, you will notice that Eastern Gray squirrels are most active at your feeders in the early morning and again in mid-afternoon.

In the winter when the days are shorter, noontime is their peak activity time.

The primary natural foods include; nuts, fruits and buds of hickory, pecan, walnut, elm, mulberry, and field corn.

To bury a nut, a gray squirrel digs a hole about 3 to 4 inches deep, puts the nut inside the hole then, pushes it down whit its nose and pulls the soil over it with its front paws.

When it wants to retrieve the nut, it goes to the general area and locates it either by the smell of the nut or by the squirrels own scent left when burying the food.
