How to Tell Gray Squirrel Genderhow to tell gray squirrel gender

If you are wondering how to tell gray squirrel gender, you are not alone. There are many ways to identify a gray squirrel, and we are going to discuss some of the most common features. The first thing to look for is its belly color. Males have gray bellies. Females are tan. You can also look for its reproductive longevity. Lastly, look for its nuts. A female gray squirrel will have a lighter belly color.


If you’re wondering how to tell gray squirrel gender, you’re not alone. There are many ways to determine a squirrel’s gender. One way is to observe its mating ritual. While you may think the size of its testicles will give you the answer, it doesn’t always. You can also look for smell and size differences. Here are some tips to help you determine whether the gray squirrel you’re watching is a male or a female:

The coloration of gray squirrels depends on the melanin gene’s location. Most gray squirrels of wild type have a white abdomen. This is due to regulatory genes that suppress melanocytes in these regions. This adaptation helps the gray squirrel blend in against the light sky. Some gray squirrels will have a tan belly instead. The coloration of a gray squirrel’s belly may vary depending on where it lives.

Belly color

If you’re wondering how to tell gray squirrel gender by belly color, the answer is quite simple. Just observe the animal’s behavior and try to distinguish sexes from each other. Male squirrels have larger scrotums and testes while females have prominent nipples and vaginal area. You’ll know which is which if the animal is sitting up and feeding its young. You can also tell whether a gray squirrel is a male or a female by its anus and genital opening.

The belly color of a gray squirrel can be white or tan. The reason for this is the color of its melanin glands. Gray squirrels have regulatory genes in certain locations that suppress the melanin production. These genes prevent melanocytes from reaching these white regions. This adaptation helps the squirrel blend in with light sky. However, there are some gray squirrels that have tan belly colors.


You can tell a gray squirrel’s gender by looking at its body. Females have a larger body than males, and they lack testicles. The testicles of males appear large and prominent during breeding season, so a female squirrel won’t have them. When they do have testicles, they are visible on the underside of their body. During the non-breeding season, female squirrels are completely covered in nuts.

If your subject doesn’t like nuts, it may not be the right species. Because females grow smaller, they may have trouble finding nuts, but if you know the gender of the squirrel, you can tell by the amount of nuts they eat. Once you’ve identified the sex of your gray squirrel, the next step is to determine which nut is their favorite. A few nuts from females will signal a female, while others will signal an unmated female.

Reproductive longevity

In the wild, grey squirrels live up to nine years. While this life span is much shorter than the average, some have been found to live up to 20 years in captivity. Reproductive longevity varies by environment and food availability. In the early 1980s, a study by John Gurnell in Southern England found that female grey squirrels have a much longer lifespan than males. This may be due to the fact that male gray squirrels spend a longer time in the breeding season.

In order to determine the reproductive longevity of gray squirrels, researchers studied the genital apparatus of the animal. This information was then used to estimate the reproductive phases of the female squirrel. This information was then used to develop a breeding program. The female squirrels were grouped into four distinct morphotypes: the regressive testicle, a nonregressive testicle, and a spermatogonia-free sex. The latter has larger nuclei but little cytoplasm and a low testicular weight.


There is a growing controversy in the scientific literature about gray squirrel gender and the origins of its distinctive coloration. While the coloration of gray squirrels varies regionally and locally, they are typically brown/gray on top and white underneath. Although gray squirrels are not genetically determined, the coloration is likely a result of the different pigments they produce, known as melanin. Melanin comes in two varieties, eumelanin and phaeomelanin. Different combinations of these two pigments create different hues. In addition to this, the squirrels’ bands of colored hairs result from this alternate use.

Gray squirrels were killed in the winter and euthanized in spring, which enabled researchers to study the effects of the environment on female and male gender development. After the research was complete, the gray squirrel carcasses were stored at -20 degC and performed a standardized postmortem and tissue sampling protocol. The resulting morphological and behavioral traits of the male and female were analyzed. Phylogenetic analysis revealed that female gray squirrels have more thoracic bone development than males.
