The fox squirrel (Sciurus niger), also known as the eastern fox squirrel or Bryant's fox squirrel, is the largest species of tree squirrel native to North America. Despite the differences in size and coloration, they are sometimes mistaken for American Red Squirrels or Eastern Gray Squirrels in areas where the species co-exist.
