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. It is sometimes mistaken for the American red squirrel or eastern gray squirrel in areas where the species coexist, though they differ in size and coloration.The word Sciurus came from the ancient Greek words skia, meaning shade, and oura, meaning tail. Niger refers to the black coloration. Wikipedia →
