Melanistic fox squirrels with completely black fur occur naturally in populations throughout the eastern United States, with some regions reporting melanistic individuals comprising up to 30 percent of local populations.

Specialized facial vibrissae allow fox squirrels to detect obstacles and navigate through dense canopy at night, with whisker sensitivity enabling precise three-dimensional spatial awareness in low-light conditions.
- 11
Territorial disputes between male fox squirrels often escalate into dramatic chasing sequences that can span multiple trees and cover distances exceeding 30 meters at speeds up to 20 miles per hour.

Litters of three to four young fox squirrels are typically born in spring after a gestation period of 44 to 45 days, with females nursing their offspring for approximately eight weeks before weaning.
- 09
Mating calls from male fox squirrels produce high-pitched chirping sounds reaching frequencies up to 8 kilohertz, audible across distances of approximately 100 meters during breeding season.
- 08
Fox squirrels employ sophisticated spatial memory to relocate thousands of buried acorns across their territory, recovering approximately 74 percent of cached nuts through scent detection over multiple seasons.
- 07
A fox squirrel's territorial range typically spans 4 to 15 hectares, with males maintaining significantly larger home ranges than females in the same population.
- 06
In urban environments, fox squirrels construct multiple dreys or leaf nests within their home range, often maintaining three to five separate nests for shelter and raising young.
- 05
Fox squirrels can rotate their hind feet 180 degrees, allowing them to descend tree trunks headfirst with their claws gripping the bark.
- 04
Their front teeth never stop growing throughout a fox squirrel's entire lifespan, requiring constant gnawing on nuts and bark to maintain proper length.
- 03
During harsh winters, fox squirrels can survive up to eight days without food by relying on their cached acorn stores buried throughout their territory.
- 02
Eastern fox squirrels display four distinct color morphs ranging from black to orange-red, with some individuals exhibiting predominantly white undersides and darker backs across their geographic range.
- 01
Weighing up to 1.1 kilograms, fox squirrels are North America's largest tree squirrels and can leap distances exceeding 4.5 meters between branches.
