Remarkable Color Variations Perhaps no North American mammal displays greater color variation than the Fox Squirrel, with regional populations exhibiting dramatically different coat patterns and colorations across their extensive range. The fox squirrel (Sciurus niger), also known as the eastern fox squirrel or Bryant's fox squirrel, [3] 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 co-exist, though they differ in size and coloration.
[5]. Squirrels come in a variety of colors across different states in the United States. The most common squirrel colors are gray, brown, black, and fox red.
There are several key factors that influence squirrel color variation between states. Appearance: The fox squirrel (Sciurus niger) weighs from one to three pounds, and exhibit color variations which range from a buff color to gray, and in some instances black. The under parts are usually lighter, and typical specimens have white noses and ears with black faces and feet.
They are noted for their long, bushy tails and for their strong hind legs which allows them to leap easily. Black squirrels are not a separate species but are melanistic forms of common species like the Eastern Gray Squirrel or Fox Squirrel. Their fur is jet black or brownish-black, depending on genetic makeup.
Another white coloration is leucism, a partial reduction in all types of pigment, rather than a complete absence of melanin. Many black fox squirrels display white patches on their nose, ears, and paws, creating a striking contrast against their dark fur. These markings help distinguish them from other dark.
This larger size gives the fox squirrel a commanding presence and distinguishes it from other members of the squirrel family. Not only are they larger, but fox squirrels also have a unique coloration. While their reddish-brown fur is the most common, some individuals may exhibit variations in color, ranging from gray to black.
The main difference between Fox squirrels and Gray squirrels are in the color of their fur. Fox squirrels have a more diverse range in colors, including gray, red, and black, while Gray squirrels only come in shades of white belly with a rusty or black outline to their tail. Fox Squirrel: Glaucomys Volans Page Contents Description Of The Fox Squirrel Weighing from one to three pounds, the fox squirrel (Sciurus niger) exhibits color variations ranging from a buff color to gray, and sometimes black.
The lower parts are generally lighter, and typical specimens have black faces and feet with white noses and ears. An albino Fox Squirrel photographed in Denton, Texas near the campus of UNT. You can pictures of this squirrel and his albino sibling here: Fox Squirrel Albinos in Denton, Texas.
There is one other possible color variation that may occur in Fox Squirrels from time to time. Melanism is the exact opposite of albinism.
