Eastern Fox Squirrel?

The best bird photo I could come up with from my morning bird walk was this squirrel photo.  I assumed it was an Eastern Fox Squirrel until I got home and started checking other photos which made me start to wonder.  I Googled “eastern fox squirrel” and selected the Oregon Department of Fish and Wildlife’s web site, which says that “The ears are short, rounded, and without tufts.” Now clearly this guy does not have small rounded ears, and the ears do have tufts. So, I am rather stumped.  But checking on all the other squirrel options, I am pretty much stuck with Eastern Fox Squirrel, just one that has big ears! If anyone has a better idea let me know.
