Interesting timing of your post...saw similar looking gray squirrel here in the back yard last week (NW Wake County)...sort of a light orange-ish/red-ish color tail...by the time I scrambled to get a camera it had moved on through...hope to get a shot if it shows up again. Searched the Internet, didn't find any specific reason, only that they can have varying color tails.This picture was taken at the shop where I work. Any of you guys ever seen one? It’s body almost had a red tint to it also. I’ve seen fox squirrels but nothing like this one.
