Squirrels are less active in times of cold weather, and instead focus their energy on staying warm in their home. They only have brief periods of activity when eating stored food and going to the bathroom. In areas where the winters do not get very cold, squirrels are more active year-round. They still store food in case it is needed, but do not have the lengthy periods of inactivity.
Squirrels will adapt their lifestyles if necessary in order to survive. Mostly vegetarians, they will eat birds' eggs and insects when vegetation is unavailable. Squirrels, who are normally territorial over their homes, will share their homes with others when body heat is needed to keep warm. When the weather warms up, the squirrels part ways.
Hope this helps,took a lot of time to write :D
