While there has always been a good number of gray squirrels nearby, this is one of the few fox squirrels I recall seeing near our home. That bushy tail may be one of the reasons behind their name.

About one and a half times the size of a gray, the fox squirrel is North America's largest. Here it's feasting on last year's box elder seeds.

Like the gray and red squirrel, the fox squirrel's color phase may vary from region to region.

Adding to its ample girth.

Smaller than both the fox and gray, the red squirrel, above, seems to be the feistiest of the three, particulary when defending its territory.

Here it's easy to see where the red got its name.   

The entire time I watched, this red seemed preoccupied in one of walnut trees growing along the north border of our property.

Here again, the red tends to a walnut tree. It seemed to concentrate on forks in the tree, perhaps enhancing future buds. Whatever, the red squirrels have established themselves in the area around the six walnut trees that are clustered into a small area. The gray squirrels, meanwhile, have been relegated to the hickory and oak trees back near the creek.
