With Winter knocking very loudly on the door, there is one animal which above all others, seems to have its work cut out preparing for the long, cold days to come. I refer of course to the Grey Squirrel (Sciurus carolinensis).
Sciurus vulgaris). Their habit of feeding at ground level - not up in the trees as the Reds do - gives the Greys the edge by being able to eat fallen acorns. The Greys also eat tree bark, all sorts of seeds and nuts, fungi and will even steal birds eggs and hatchlings. With such a wide variety of food stuffs, it's easy to see why they have thrived far more than the Reds.
