eastern gray squirrel

All I can say is they looks nothing like western grays!

Karen, the fox squirrels I have seen all keep a reddish underbelly year round. It's what gives them their distinct name. They are also much larger than the eastern greys. This looks like a typical eastern grey, although it has quite a bit of brown in it's coat, it could simply be a mutated color phase of the Grey squirrel. Only recently have I seen the fox squirrel in her NY, also finding more and more of the eastern Black Squirrels here as well. http://en.wikipedia.org/wiki/Black_squirrel It's a recessive color phase, however for some reason it's becoming more and more prominent in this area.

If I remember correctly, they do the same thing that Douglas Squirrels do and their bellies turn white in fall/winter

My impression was that fox squirrels didn't have the white belly, while eastern grays do. I may be wrong - I don't know much about squirrels.

Looks more like a fox squirrel
