When Do Squirrels Nest?

Squirrels continue building nests into September and October in order to survive winter. They'll usually build winter nests in more protected, covered areas in order to insulate themselves from the wind. All squirrel dreys tend to incorporate the existing architecture of the trees the squirrels build them around.

What time of year do squirrels give birth?

Squirrel birthing and mating season occur twice a year. Squirrel mating season happens once between December and February, then again in late June through August. With the gestation period lasting 38 to 46 days, female squirrels will give birth in early spring (February through April) or late summer (August/September).

Do squirrels come back to the same nest?

Squirrels are creatures of habit and are not as selective as other warm-blooded mammals in the rodent family. Squirrels usually have no problems returning to previous nests they have built and reuse them.
