![]() Fox squirrels have excellent vision and well-developed senses of hearing and smell. To help with climbing, the squirrels have sharp claws, developed extensors of digits and flexors of forearms, and abdominal musculature. In the South, there are isolated communities with uniform black coats. There are three distinct geographical morphs in coloration: In most areas, the animal's upper body is brown-grey to brown-yellow with a typically brownish-orange underside, while in eastern regions, such as the Appalachians, there are more strikingly-patterned dark brown and black squirrels with white bands on the face and tail. Individuals tend to be smaller in the West. There is no sexual dimorphism in size or appearance. The fox squirrel's total length measures 20 to 30 in (50.8 to 76.2 cm), with a body length of 10 to 15 in (25.4 to 38.1 cm) and a similar tail length. Despite the differences in size and coloration, it is sometimes mistaken for American red squirrels or eastern gray squirrels in areas where the species co-exist. 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. shermani – Sherman's fox squirrelįox squirrel's range (excludes introduced populations) rufiventer– western fox squirrel or Say's fox squirrel ![]() cinereus – Delmarva Peninsula fox squirrel ![]() avicinnia – mangrove fox squirrel or Big Cypress fox squirrel
