Eastern Gray Squirrels
The Eastern Gray Squirrel (Sciurus carolinensis), or the Grey Squirrel, depending on region, is a tree squirrel native to the eastern and midwestern United States and to the southerly portions of the eastern provinces of Canada. The native range of the Eastern Gray Squirrel overlaps with that of the fox squirrel (Sciurus niger), with which it is sometimes confused, although the core of the fox squirrel's range is slightly more to the west.
A prolific and adaptable species, the Eastern Gray Squirrel has been introduced to, and thrives, in several regions of the western United States. It has also been introduced to Britain, where it has spread across the country and has largely displaced the native Red Squirrel, Sciurus vulgaris. In Ireland, the red squirrel has been displaced in several eastern counties, though it still remains common in the south and west of the country. There are concerns that such displacement might happen in Italy and that Grey squirrels might spread from Italy to other parts of Mainland Europe.
As the name suggests, the Eastern Gray Squirrel has predominantly gray fur but it can have a reddish color. It has a white underside and a large bushy tail. Particularly in urban situations where the risk of predation is reduced, both white- and black-colored individuals are quite often found.
Like many members of the family Sciuridae, the Eastern Gray Squirrel is a scatter-hoarder; it hoards food in numerous small caches for later recovery.Eastern Gray Squirrels breed twice a year, December to February and May to June, though this is slightly delayed in more northern latitudes.
