What Is the Squirrel Population in the United States?
If you live in the United States, you may be wondering, “What is the squirrel population like?” If so, there are three main species of squirrel: Red squirrels, Grays, and Foxes. Despite the similarity in habitat, there are some differences between the three species. In addition to their unique looks and personalities, these three species can also be found in suburban areas. So, which is the largest squirrel population in the country?

Gray squirrels
There are several ways to maintain a healthy gray squirrel population. The most important is to provide a diverse range of quality habitat for the species. For example, gray squirrels like mature oak trees, which are rich in cavities. By providing these species with a diverse range of habitat, we can ensure their presence. And a large part of this is by reducing fire fuel. For this reason, forest managers are designing habitat conservation and enhancement practices.
A gray squirrel’s home range can be anywhere from 1.5 to 8 acres, although in high-density areas, home ranges are smaller. Gray squirrels develop social hierarchies and are grouped by sex and age. Dominant gray squirrels are likely to have a larger home range than their subordinates. And if a female becomes pregnant, she may not give birth. It may also remain in the same location for more than a year.
The Eastern gray squirrel’s gestation period is approximately 44 to 45 days. Young are born with full coats of fur, and weaning occurs within the first week of life. The young may remain with the mother until the age of 12 weeks. After that, sexual maturity occurs, and the female is then ready to reproduce. Once a female reaches sexual maturity, she will give birth to two litters a year, usually in late winter and midsummer. The young are born blind and hairless, but develop a furry coat by the end of the summer or early fall.
Red squirrels
Recent research shows that red squirrels are under-represented in some areas of the continental U.S., particularly the northeast. A recent study of alarm calls in Red squirrels identified a 45,5-hectare area in downtown Fairbanks, Alaska, as a prime red squirrel habitat. Moreover, the study also found that red squirrels abandon their winter food caches in the summer, while they defend prime territories throughout the year. This is a big boon to the red squirrel population, but it also raises the issue of how to protect them from habitat loss and degradation.
The diet of the Red Squirrel is primarily comprised of conifer seeds, but this does not exclude other foods. These animals also clip mushrooms and consume them. In addition to eating seeds, they also tap maple trees to obtain sap. Once the sap evaporates, they return to consume it. Red squirrels are active throughout the year, and they travel through snow tunnels. However, there is concern over the red squirrel’s ability to breed.
Several studies have looked at red squirrel density in different regions. One study suggested a correlation between density and amount of white spruce cones, which are vital for red squirrels’ diet. Another study found that annual fur harvests and ovulation rates correlated with red squirrel population density in Alberta. Hence, red squirrels may be under or over-dispersed in some areas.
Fox squirrels
The Eastern Fox Squirrel is a common pest in the United States. They are known to eat plants, bird eggs, and carrion. These squirrels also use residential areas as nesting and food sources. Their diets are primarily comprised of nuts, fruits, and seeds from oak, hickory, and walnut trees. Additionally, they enjoy the seeds and buds of hawthorne and mulberry trees.
The eastern fox squirrel is one of the most dangerous species in the United States. It has many predators and has developed a distinct alarm call. Increasing overhunting of these animals has also threatened their survival. This species of squirrel has become a popular subject of wildlife-friendly conservation. But there is still a great need for more research into its ecology and biology. While many researchers have focused on the Western fox, there are still several subspecies in the United States.
The Eastern Fox Squirrel is a social mammal. It spends most of its time on the ground and does not engage in territorial behavior. Although it is not territorial, it does use its scent markings to communicate with other squirrels and defend its nest aggressively. Male fox squirrels are more aggressive during mating season and during the dispersal of young. And while it is not uncommon to find an adult female fighting a male squirrel, the latter can also be aggressive.
Jessica Watson is a PHD holder from the University of Washington. She studied behavior and interaction between squirrels and has presented her research in several wildlife conferences including TWS Annual Conference in Winnipeg.
