How to Tell If a Squirrel is a Boy Or Girl
There are a few ways to determine whether a squirrel is a boy or a girl. Males and females have very different characteristics. For example, female ground squirrels emerge from hibernation later than their male counterparts, and Grey squirrels produce two litters of 2-4 young. While males have two distinct types of genitalia, females have only one.
Grey squirrels produce 2 litters of 2-4 young
The gray squirrel is a small, native species found in eastern U.S., including southern Quebec, New Brunswick, Ontario, eastern Texas, and northern Manitoba. The species has been introduced to areas outside its native range, and is now found in every county of Maryland. A male grey squirrel will typically produce two litters of 2-4 young during their lifetime. While the gray squirrel is not common anywhere in the United States, it has been adapted to life in urban areas.
Female grey squirrels are usually pregnant for 44 days. Females begin reproductive life when they are one and a half years old, and they may give birth to young as early as 5.5 months old. Once they reach sexual maturity, the male will typically mate with the female. The male will reach sexual maturity at about 11 months of age, but may delay his maturation by up to two years if he lives with a dominant female. Male gray squirrels typically have two litters a year, with the first born occurring in the winter and second litters in the summer.
Female red squirrels mate with as many males as possible
If you’ve ever wondered why red squirrels are so promiscuous, the answer may surprise you. This promiscuous behavior has nothing to do with genetics, but it has to do with how many males knock on a female’s door. According to University of Guelph researcher Eryn McFarlane, female red squirrels will entertain as many males as possible, ranging from one to fourteen.
The female red squirrel enters her “heat” period only one day a year. During this time, she releases three or four eggs to be fertilized. She also leaves her scent around to encourage males to chase her. When she is ready, she will mate with as many males as she can find. However, McFarlane is still researching why some females attract more males than others.
While multi-female mating is common in the animal kingdom, it’s unclear why females would choose to mate with as many males as possible. Although this strategy may have evolutionary benefits for female red squirrels, it also poses a host of problems. For starters, multiple partners increase the chances of surviving. But, if the females were more selective in choosing mates, it could end up causing problems.
Female ground squirrels emerge from hibernation later than male counterparts
In general, female ground squirrels emerge from hibernation a few weeks later than their male counterparts. This is because females spend longer in hibernation than males, and females have lower body temperatures. They also lose more weight than males. In the arctic, female ground squirrels enter hibernation in August and males emerge from hibernation three weeks later.
The timing of females emerging from hibernation is dependent on the timing of the late spring snowmelt. Females emerge from hibernation later than males, which allows their offspring to grow more and prepare for winter hibernation. Females may also mate during early spring but the timing of the first emergence is variable, up to six weeks later. Late spring snowstorms can suspend mating and cause heavy mortality.
Male and female ground squirrels are similar, with the exception of size. Males are larger and weigh about 5-10 pounds more than females. The male’s scrotum is larger than the female’s, and the female’s nipples are more prominent during mating season. Males are larger than females, and their testes are much closer to their anus.
Female flying squirrels glide
Although the gender of a flying squirrel is ambiguous, it is known that females have a slightly increased gliding rate compared to males. The ratio of glide speed to flight speed is dependent on the direction of wind and localized variation in wind speed. Gliding squirrels can reach speeds of up to 40 mph and are capable of extending their range over a great distance. Researchers have studied the gliding speed of flying squirrels in both the laboratory and the field, and have documented glide speeds of up to 70 km/h.
While some species of flying squirrels glide, they are not considered to be true gliding animals. Instead, they glide from tree to tree using a furry membrane called patagium, which connects their wrists and ankles. This membrane acts like a hang glider, slowing their descent and allowing them to control their direction. Because flying squirrels cannot fly, they glide instead. While the ability to glide is impressive, it does not mean that flying squirrels are capable of flight.
How can you tell if a squirrel is a boy or girl?
You can determine the gender of a squirrel by looking at its genitalia.

What is another way to tell the difference between a male and female squirrel?
Male squirrels are typically larger than female squirrels.
How can you tell if a squirrel is a boy or girl if you can’t see its genitalia?
