The eastern fox squirrel is a medium-sized tree squirrel with some remarkable physical characteristics. Their dorsal pelage is buff to orange, while their venter is rufous, with some varieties in the southeastern United States being black.

Fox squirrels have 8 mammae, which is a notable feature of their anatomy. Their tail is well furred, and ear tufts often develop in winter.

One of the most distinctive features of the eastern fox squirrel is its ability to climb, made possible by sharp recurved claws, well-developed extensors of digits and flexors of forearms, and abdominal musculature.

Here are some key physical measurements for the eastern fox squirrel:

Fox squirrels are a medium-sized tree squirrel with no sexual dimorphism. They have a distinctive physical appearance that sets them apart from other squirrel species.

The dorsal pelage, which is the fur on their back, is buff to orange in color. In some varieties, found in the southeastern United States, the fur can be black.

Their venter, or belly, is a rufous color, which is a reddish-brown hue. This is a key feature to look for when trying to identify a fox squirrel.

Fox squirrels have sharp recurved claws, well-developed extensors of digits and flexors of forearms, and abdominal musculature, all of which are adaptations for climbing.

Here are some key physical features of fox squirrels:

Fox squirrels can range in mass from 696.0 to 1233.0 grams, or 24.53 to 43.45 ounces, with an average mass of 800.0 grams, or 28.19 ounces. Their length can range from 454.0 to 698.0 millimeters, or 17.87 to 27.48 inches, with an average length of 595.0 millimeters, or 23.43 inches.

Fox squirrels show a lot of variation in their pelage coloration, especially when it comes to brightness. The greatest variation is along the L axis, which measures brightness.

The coloration of fox squirrels' heads is quite uniform, with a narrow range and low standard deviation along all three color axes. This means that head coloration is relatively consistent across the population.

Ventral areas, on the other hand, have a wide range and large standard deviation for all color axes. This suggests that there's a lot of variation in the coloration of fox squirrels' bellies.

The dorsal metrics, including shoulder, dorsum, and rump, are similar along the a and b axes, which measure green to red and blue to yellow coloration, respectively. This means that these areas have a similar color tone.

However, the L value, which measures brightness, is different for each of these areas. The shoulder and dorsum have similar L values, but the rump has a higher L value and lower standard deviation. This indicates that the coloration of the rump lightens compared to the central portion of the dorsum and the base of the tail.

The eastern fox squirrel is a master of adapting to its surroundings, and its habitat is no exception. These woodlots are typically 10 to 20 acres in size with a sparse understory and are separated from one another by large acreages of agricultural croplands.

Fox squirrels have a keen eye for food sources, and they make use of various tree species for sustenance. Hickory, oak, beech, black walnut, maple, elm, and buckeye trees are all favorites for their nuts and other edible resources.

Leaf nests are a common sight in these woodlots, constructed from leaves and twigs in the crotches of tree branches. Dens, on the other hand, are formed in hollow tree trunks or branches, providing a cozy shelter for the squirrels.

Fox squirrels are opportunistic eaters, and their diet reflects this. Nuts from hickory, oak, and beech trees are staples, as are fruits from blackberry, dogwood, wild cherry, and wild grape bushes. They also enjoy a good corn snack, as well as the buds of maple, elm, and willow trees, and insects are a tasty bonus.

The eastern fox squirrel is a fascinating creature. It's one of four squirrel species in Ohio, and it's the largest of them all.

Native to the Midwest prairie edge, the fox squirrel wasn't originally an Ohio inhabitant. They preferred open areas and fewer dense woodlots.

Only after settlement cleared some of the dense woods away did the fox squirrel start to make Ohio its home.

Eastern fox squirrels have a unique predator in the Cooper's hawk, which is known to prey on them in urban areas.

They are also vulnerable to foxes, coyotes, and domestic cats, which are common predators in their range.

Red-tailed hawks and great horned owls are other birds of prey that may target eastern fox squirrels.

These predators often attack squirrels in trees, where they are most vulnerable.

Eastern fox squirrels have a few natural defense mechanisms, including their agility and ability to jump quickly to safety.

However, their reliance on human-altered landscapes can make them more susceptible to predators.

In some areas, eastern fox squirrels have adapted to living alongside humans and can even be found in urban parks and backyards.

Despite these adaptations, their populations are often threatened by habitat loss and fragmentation.

The eastern fox squirrel is found throughout a significant portion of North America. They inhabit the eastern and central United States, extending south into northern Mexico and north into Canada.
