Eastern Gray Squirrel
For the eastern gray squirrel, mating can begin in December or January. The males will fight to determine dominance, and the winner will have a better chance to reproduce. The winner persues the female through the trees until they are stimulated enough to majority of litters are born in March, which the female squirrels are already preparing for now. The eastern gray squirrel does not hibernate in Washington; however, their activity will slow a bit. There are usually several dens that are occupied throughout the year as well as several nests built high in the tree canopy. This would be the best scenario with the eastern gray squirrel. Unfortunately, it is more common to find these squirrels in homes or commercial buildings. Eastern gray squirrels are notorious for getting into man made structures, so much so that they are most commonly found in urban areas as opposed to the other native squirrels in Western Washington. Manmade structures, such as our nice, cozy homes, have become the new norm in terms of where they will co-habitate. Squirrels have been known to store their food cache in attics during the winter, where normally the cache would be stored underground, in tree hollows, or rotting trees.
