What Are the Advantages of the Gray Squirrel?
The eastern gray squirrel prefers mature woodland ecosystems where mast-producing trees are abundant, providing ample food for the animal. This species favors oak-hickory hardwood forests over coniferous forests due to their greater abundance of mast forage. Eastern gray squirrels live only in parts of eastern Canada that are not covered by the boreal forest. The eastern gray squirrel is an excellent example of a small, native rodent.
Habitat
The eastern gray squirrel can enter estrus as early as five months of age, although females do not become fertile until about one year of age. The male stimulates ovulation in the female during the time of estrus. Male eastern grays reach sexual maturity between one and two years of age. The reproductive lifespan of female gray squirrels is eight to twelve years, and males live for up to 20 years. However, in captivity, eastern gray squirrels are more likely to live a shorter life than they do in the wild.
The eastern gray squirrel is found in the eastern half of the United States. These animals live in forests with a combination of deciduous and mixed forest types. The species thrives in tall trees that offer plenty of food sources and nesting spots. It prefers oak-hickory hardwood forests over coniferous forests, and is most common in parts of the eastern United States and Canada without a boreal forest.
Life expectancy
The average gray squirrel lives between six and twelve years. However, in captivity, some squirrels have been known to live up to 20 years. The lifespan of these creatures is dependent on the environment in which they live. Some free-range squirrels may live up to 13 years, while others may not reach that age. The Smithsonian National Museum of Natural History estimates the lifespan of the gray squirrel at eleven months to twelve years.
Although grey squirrels are tough and can survive the winter months without any trouble, there are many threats to their health. Despite their tough exteriors, the creatures are susceptible to predators and can even succumb to parasitic infections. These diseases can lead to extensive loss of fur and eyesight and even cause death. To combat these threats, the grey squirrel must stay healthy by eating a variety of food sources and exercising as often as possible.
Food supply
In the Fall of 1972, scientists examined the effects of supplemental food supply on gray squirrel reproduction. The scientists found that the mast in one Experimental woodlot was scarce or nonexistent. In May 1973, one of the Experimental woodlots emigrated and the remaining squirrels remained in the Control woodlots. The researchers concluded that supplementation of food supply increased the survival rate of gray squirrels and improved reproduction rates. In this article, we review the findings of this study to better understand the role of food supply in the gray squirrel population.
When temperatures drop and the snow flies, gray squirrels remain in their dens and rely on cached mast stores and fat reserves for their winter food supply. This allows them to remain active throughout the winter, as long as temperatures don’t drop below freezing. However, they must be cautious in their foraging activities, as any risk they take has to pay off. If the foraging attempts do not produce enough profit, the gray squirrel will not be able to maintain the protective fat layer.
Hunting seasons
The hunting seasons of the gray squirrel vary greatly in most regions, but the general pattern is the same: autumn and winter. In the late summer and early fall, the gray squirrels are active, but not nearly as abundant as in the spring. As a result, hunters should concentrate their efforts in the early morning and late evening, when the leaves are still on the trees. By early winter, the gray squirrels become late risers, preferring to wait until the weather is warm enough to leave their tree cavities and nests.
The House Fish and Game Committee reverted the bill’s intent on Jan. 25. At Rep. Tim Lang’s request, the committee changed the bill to allow hunting during the week. Depending on the type of license, the junior season could last anywhere from six days to eighteen. Currently, the gray squirrel hunting season is open six days a week from Sept. 11 to Nov. 13, except for Sunday, Nov. 14. In addition, it can be hunted on Saturdays, Sundays, and holidays.
Distribution
The gray squirrel’s invasion of the United States has resulted in some interesting challenges in ecology, conservation, and forest management. Its destructive habits, such as digging holes in trees for food, make them an increasingly common pest of the woods. Because of this, the Forest Commission has published annual distribution maps of gray and red squirrels in state-managed forests. To better understand their distribution and ecology, it is helpful to look at historical data.
The gray squirrel is native to eastern North America and western Canada, with its current range extending west of the Mississippi to Canada. Although native to eastern North America, gray squirrels are now found in England, Ireland, Northern Italy, and Western Canada. The species was introduced to the English countryside in the 1870s and rapidly adapted to native forests. This species is slightly larger than its cousin, the Red squirrel, but weighs only half as much as it does.
