If you’re unsure of the sex of your pet’s western grey squirrel, you may not know how to spot the difference between a male and a female. Luckily, there are several ways to determine the sex of a western grey squirrel. Below, we’ll discuss testicular regression, size, and color. You can also see whether the sex of your pet’s fur matches its markings on its body.

Female

The mating behavior of the female western gray squirrel is unclear. Western gray squirrels are known to bite each other during breeding season, and have highly territorial behaviors. This species mates once a year, from December to June. The gestation period is approximately 43 days and the young are born without fur. The litter size ranges from three to five young. Baby western gray squirrels weigh about one ounce and are approximately one inch long. They become sexually mature when they reach around six months old.

The native range of the western gray squirrel in Washington state is very limited compared to the rest of its range. The species is found in only three isolated populations. In Washington, they inhabit transitional forests with mature Oregon white oak, ponderosa pine, and Douglas-fir. It also inhabits riparian areas with various tree species. The species is considered low-density, and the WDFW believes its population is not as diverse as it once was.

Testicular regression

The western gray squirrel is a threatened species in Western Washington and Oregon. The animal is known for its unique physical traits. The adult western grey squirrel has seven toes and nine plantar tubercles on each hind foot, and extra digits are articulated with supernumerary cuneiforms. This form of polydactylism is rare in wild adult rodents, and the western grey squirrel is associated with the Oregon white oak.

The testes start growing in late November and begin to descend into the scrotum. They are typically dark brown or black, and may be stained with urine. Male squirrels go through two periods of spermatogenesis. They breed throughout the year, and in a good mast year, they tend to have two litters. However, the testes in females do not retract into the scrotum.

Size

The size of the western gray squirrel is usually between eighteen and twenty-four inches. It can weigh between twelve and thirty-two ounces. The fur of this species is silver gray with white undersides and a long, bushy tail. The tail is not tufted and measures between eighteen and twenty-one centimeters (four to seven inches). These animals shed their fur twice per year, during the late spring and fall molting seasons.

The Western gray is a woodland creature that needs a continuous stretch of mature oak trees. They are more likely to feed in an up-a-tree location than on the ground. In addition, they prefer fungi that grow underground. Western grays do not use fragmented habitats. They also prefer to stay in solitary burrows. Their diet includes pinecones, acorns, and seeds.

Color

If you want to identify a particular gray squirrel, you can learn its sex by watching its mating ritual and chase. Male squirrels have different genitalia from females. You can even distinguish the two by the way their undersides look during breeding season. You can also look for the presence of testicles to determine the sex. This article provides information on how to tell the sex of a gray squirrel and the signs you should look for.

The western gray squirrel, Sciurus griseus, lives primarily in the western United States. They inhabit the mountainous regions of California, Oregon, and Washington. Their home ranges are between 0.5-7 hectares in size. Males have larger homes. The western grey squirrel weighs between 350 and 950 grams. They have large ears, but no tufts. They spend their time on the ground and in trees.

Calling

Despite the fact that they have the same name, how to tell the sex of a western gray squirrel can be tricky. The answer to this question depends on the species. Male gray squirrels are larger than females and weigh about one and a half pounds at maturity. They measure about 18 inches long and have large, bushy tails that are not much different from each other. A male gray squirrel usually mates with only one female at a time.

Eastern gray squirrels have predominantly gray fur, but can have a brownish hue on their backs. They also have large bushy tails, and are often found in urban settings. Interestingly, you can also find the melanistic form, which is almost entirely black and is dominant in certain geographic areas and populations. The black tails and undersides of these squirrels are genetic differences between the two sexes.
