Question: when are squirrels born in minnesota?
Answer: Reproduction. Gray squirrels mate twice a year, typically from December to February and /or June through August. They nest in tree hollows or in a tree-top den, which is a 12- to 19-inch ball-shaped nest made of leaves, twigs and bark. Mother squirrels have 2 to 4 babies, which are born hairless and weigh 1/2 ounce.
