The fox squirrel is the biggest tree squirrel. It’s around 10-15 inches long. It comes in three different colors, depending on where it lives. In the northeast, it’s gray on top and yellowish underneath. 

In the west, it’s gray on top and rust-colored underneath. In the south, it’s black and brown with a white stripe on its face and a white tip on its tail. Some people also call it the eastern fox squirrel.

There’s a type of fox squirrel called the Delmarva fox squirrel, which used to live in parts of Delaware, Maryland, Pennsylvania, and New Jersey. 

Now, it’s mostly found on the eastern shore of Maryland and Virginia. It looks like a regular fox squirrel, but it has a bushy tail and is gray with a white belly.


Fox squirrel range image

The fox squirrel, or eastern fox squirrel, has a broad distribution across North America, ranging from the eastern and central United States all the way to parts of northern Mexico and southern Canada. Specifically:

Eastern and Central United States

The fox squirrel can be found throughout the eastern and central regions of the United States, extending westward to states like the Dakotas, Colorado, and Texas. However, it is notably absent from certain areas including New England, most of New Jersey, western New York, and northern and eastern Pennsylvania.

Northern Mexico and Southern Canada

The species also extends its range into parts of northern Mexico and southern Canada, including regions in northern Mexico and provinces in southeastern Canada such as Ontario, Quebec, New Brunswick, and Nova Scotia.

This extensive range demonstrates the adaptability of the fox squirrel to various habitats and climates within its distribution, from the dense forests of the eastern United States to the grasslands and woodlands of the central regions, and even into urbanized areas. 

However, there are localized gaps in its distribution due to factors such as habitat suitability, landscape fragmentation, and historical population dynamics.


Fox squirrel Habitat Image

The fox squirrel, or eastern fox squirrel, thrives in a diverse array of habitats across its extensive range. 

From the lush expanses of deciduous forests to the mixed woodlands that blend deciduous and coniferous trees, these squirrels find ample resources for sustenance and shelter. 

Urban and suburban areas have become increasingly familiar territories for fox squirrels, where they exploit the abundance of trees in parks and neighborhoods, as well as human-provided food sources. 

Agricultural landscapes, including orchards and farmlands, also host populations of fox squirrels, although conflicts with farmers over crop consumption can arise. 

Additionally, in regions with open spaces like grasslands and scrublands, fox squirrels adapt to the presence of suitable tree cover. 

In the southern reaches of its range, the fox squirrel demonstrates its versatility by inhabiting swampy environments such as cypress and mangrove swamps, where they navigate the unique challenges posed by these ecosystems. 

This adaptability underscores the fox squirrel’s remarkable ability to thrive in a wide variety of habitats, making it a resilient and widespread species across North America.


Fox squirrel Diet Image

The fox squirrel has a diverse diet that includes a variety of foods found in its habitat. This includes acorns, hickory nuts, walnuts, beech nuts, mulberries, and hawthorn seeds. 

They also consume green shoots, buds, fruits, berries, and corn. Additionally, fox squirrels supplement their diet with insects such as moths and beetles.

One interesting behavior of fox squirrels is their habit of storing nuts for winter use. They carefully stash nuts in various locations, often burying them in the ground or hiding them in crevices in trees. 

Their keen sense of smell helps them locate these hidden caches during times of food scarcity in the winter months.

This behavior of caching food not only helps fox squirrels survive during lean periods but also plays a role in seed dispersal, as forgotten caches may sprout into new plants. 

Overall, the fox squirrel’s varied diet and clever foraging strategies contribute to its success as a species in diverse habitats across North America.

Life Cycle

The reproductive behavior and life cycle of the fox squirrel are fascinating and adaptable to various environmental conditions. Here’s a detailed breakdown:

Mating Behavior

Fox squirrels have a flexible mating season, with the ability to mate throughout the year, although peaks in mating activity typically occur in December and June.

During mating season, multiple males may pursue a female, engaging in chasing or following behaviors.

Competition among males is common, with the successful male earning the right to mate with the female and subsequently protecting her from other males.

Gestation and Birth

After mating, the female undergoes a gestation period of approximately 45 days before giving birth.

Birth typically occurs in a nest located in a hollow tree or other suitable nesting site.

The litter size ranges from two to four young, although larger litters are possible.

Early Development

Newborn fox squirrels are born hairless and blind, relying entirely on their mother for warmth, nourishment, and protection.

Their eyes begin to open around five weeks of age, gradually gaining sight.

The young are weaned from their mother’s milk at around eight weeks old.

Exploration and Independence

As the young squirrels grow, they become more active and curious about their surroundings.

They start climbing within the nest tree at around seven or eight weeks old, honing their climbing skills.

By about ten weeks old, they begin venturing down to the ground, exploring their environment more extensively.


Fox squirrel kits become increasingly independent by around three months of age, able to forage and navigate their habitat on their own.

At this stage, they continue to learn vital survival skills from observation and experience, preparing them for adulthood and eventual reproduction.

Throughout this life cycle, the fox squirrel exhibits remarkable adaptability and resilience, allowing it to thrive in a variety of habitats across its range.


the fox squirrel typically leads a solitary lifestyle, although it may tolerate the presence of other squirrels in shared feeding areas. 

Much of its day is devoted to foraging, gathering, and storing food for future consumption, activities essential for its survival, especially during times of scarcity.

When it comes to nesting, the fox squirrel shows adaptability to its surroundings. Ideally, it seeks out tree hollows as nesting sites, which provide natural protection from the elements and predators. 

However, in instances where suitable tree hollows are unavailable, the resourceful squirrel constructs leaf nests, known as dreys, in the crotches or branches of trees. 

These leaf nests serve as temporary shelters, offering a secure refuge for resting and raising offspring.

This behavior highlights the fox squirrel’s ability to utilize available resources creatively, ensuring its survival and reproductive success even in environments where natural nesting sites may be scarce or absent.


the fox squirrel is a fascinating critter native to North America. It’s known for being really good at adapting to different environments, whether it’s the woods or city parks. 

We’re fascinated by how smart and charming these little guys are. Let’s all pitch in to protect the habitats where fox squirrels live so that future generations can also enjoy watching them scamper around.
