There are more than 200 species of squirrels (family Sciuridae) around the world. The smallest squirrel species, like the African pygmy squirrel (Myosciurus pumilio) weigh only half a pound and measure five inches long. The black giant squirrel (Ratufa bicolour) is the largest species, weighing up to four pounds and growing up to 36 inches long. Squirrels nurse in similar ways regardless of species, and baby squirrels eat an omnivorous diet after weaning off their mothers' milk.
Squirrel Mating
While female squirrels only mate two or three times a year, males can mate continuously. When trying to get the attention of a female, the male proceeds to slap trees with his paws and chatter loudly. After mating, the males leave the female alone to raise their babies, often called pups. Once the young have left the nest, the male may try to mate with the same female again.
Squirrel Breeding
After mating, squirrel gestation is usually around 35 to 45 days. Most squirrels birth between two and eight babies per litter. A mother squirrel can have several litters per year. The mother will build her nest in a burrow or high up in a tree, depending on whether she is a ground or tree-dwelling squirrel. When they are first born, baby squirrels are blind and entirely reliant on their mothers to survive.
Female squirrels are very protective of their young. If an unprotected nest of baby squirrels is found, they should be left alone. Mothers will leave the nest at times to eat, but they will not go too far. If she hears her babies being disturbed, she will run back to the nest.
In the wild, North American red squirrels (Tamiasciurus hudsonicus) sometimes adopt the orphaned babies of close relatives. Whether or not she adopts a relative's babies depends on how many of her own she has.
Adopting other babies can put her own at risk as there are more mouths to feed. For example, if she only has two of her own, she may adopt nieces and nephews if they are orphaned, but if she has three, she may only adopt grandchildren or siblings that she is more closely related to.
Mothers Nursing Baby Squirrels
Squirrels have up to ten mammary glands with parallel sets of nipples running down their chest. A lactating female is easily recognizable as her nipples elongate and she loses the hair around them. These body changes make it easier for her babies to latch onto a nipple when feeding. Squirrels feed their babies milk every two to four hours until they are weaned onto solid foods and are ready to leave the nest.
Once their eyes have opened and they are ready to start weaning to solid foods, they follow their mother around the nest site. If the population density in an area is low, the young females will build nests nearby to raise their young.
If the population density is high, they will have to venture further once they leave their mother.
When Do Squirrels Leave the Nest?
The time it takes for a baby squirrel to become independent varies between species. For example, North American gray squirrels (Sciurus carolinensis) open their eyes at around four weeks old and are ready to leave their mothers by the time they are ten weeks old. Grey squirrels typically have two litters per year.
Prevost's squirrel (Callosciurus prevostii), native to Southeast Asia, generally has three litters per year and the young are fully independent at six weeks old.
Nursing Orphaned Baby Squirrels
Baby squirrels are best left with their mothers, but those that end up being hand-fed in captivity should be fed warm puppy formula with a syringe. Drinking formula gives them the best nutrition possible next to drinking their mother's milk.
Baby squirrels also need to have their genitals massaged several times a day to stimulate them to urinate and defecate, something their mother would normally do.
By the time they are two to three months old, they should be eating a mostly solid diet of fruit, vegetables, nuts and seeds. Weaning from milk to solids should be done over several weeks as their digestive system needs time to adapt to solid foods. A highly nutritious diet is vital for healthy growth and development.
Squirrel Lifecycle: When Squirrels Mate and Have Babies
Have you ever seen two squirrels chasing one another across your yard or up and down trees? They’re not merely playing; they’re flirting! The male squirrels are pursuing the females to mate with them, and afterward, the females will give birth to 2-8 baby squirrels.
Squirrel Mating: Mother Lures, Father Pursues
When a female squirrel is approximately one year old, and the weather starts warm from winter to spring, she will begin to emit specific pheromones and make chirping noises.
These scents and sounds attract male squirrels and alert them that a female is fertile. Males are fertile all year round, but females only once or twice a year, so the males become very excited when they hear and smell a female ready to produce young.
The males in the area will seek out the female and then chase her for the opportunity to mate with her. If two males are pursuing her at the same time, they will fight each other for the chance. Older male squirrels are normally larger and so will win the fight against a younger male. Most squirrels, with the exception of Red squirrels, are non-territorial, so this is the only time they will act aggressively toward one another. Even in this case, however, the squirrels do not injure one another. They merely chase and try to intimidate one another until one submits and flees the scene.
Once a male catches up with and wins the undisturbed opportunity to mate with the female (mating only takes about a minute), he finishes by ejaculating a waxy plug into the female’s vagina.
This plug prevents the sperm of other males from impregnating her, though it can fail, and one litter can be produced by multiple fathers.
The female will continue to attract males with her pheromones and chirping for about two weeks to ensure that she is pregnant. After a male has mated with her, he might return to her to mate again but will not be involved with her during her pregnancy or afterward. He has no other role to play than mating with her to produce young.
It is essential that the female produce these pheromones and vocalizations because squirrels are color-blind. They see everything in shades of black, white, and gray, and squirrels do not mate with other species of squirrels. An Eastern gray squirrel does not mate with an American red squirrel, nor does a Northern flying squirrel mate with a Fox squirrel. They rely on scent, sound, size, and fur markings to help them know and mate with their own species.
Squirrel Mating Seasons and Identifying Your Squirrels
The five most common squirrel species in America are the Eastern gray, the American red, the Fox squirrel, Northern flying, Southern flying, and Ground squirrel.
You can identify each by sight, and they each have slightly different mating habits.
Eastern gray squirrels are gray or silver with a white belly. They are about 18-20 inches long, including their tail. Some are all white (albino) and others are all black. They are common in the Eastern United States, meaning east of the Mississippi River. They like to live in nut-bearing trees and will build their nests out of sticks and other materials on tree branches or in hollowed cavities of tree trunks. They’ll take over holes that a woodpecker made or damaged areas where a tree branch fell off as long as it’s high enough off the ground to protect them from foxes, coyotes, snakes, and other predators. The ideal height for a squirrel nest is 40-60 feet off the ground. Eastern gray squirrels commonly breed in late winter or early spring, and then again in the middle of summer.
American red squirrels can be found all over the United States. They are smaller than gray squirrels, about 9-10 inches long, with reddish-brown fur and a white underbelly.
They grow tufts of fur on their ears in the winter and like to make their nests in conifer (evergreen) trees rather than leafy deciduous trees. You can also tell if you have Red squirrels in your area if you find a large cache of nuts hidden in a hollowed log or in the ground. They do not hide nuts one by one but in a large pile. They will also chase other squirrels out of their territory, even if the other squirrels are larger. They mate twice per year in late winter and mid-summer, but the females are only fertile one day each breeding season. The male who mates with her will do so multiple times in a row to ensure that she becomes pregnant on that one day.
Fox squirrels are very similar to Gray squirrels but have spread from the eastern to central states. The difference in appearance is that Fox squirrels have reddish-gray fur with orange-tinted bellies. They mate most often in January and only bear one litter per year.
Flying squirrels are nocturnal while others are active during the day.
They are 8-10 inches long, the same size as Red squirrels, and have grayish-brown fur with white undersides. You can tell if you have Flying squirrels by tapping on the trunks of your trees with a stick. The sleeping fliers will poke their heads out of the nests to see what all the racket is about and to determine if they need to escape to a safer location. Southern flying squirrels breed in late winter or early spring and then again during the summer months. Squirrels of the Northern variety only breed during the first period. You can tell the difference between the two because Southern fliers live in deciduous trees while Northern fliers live in conifers. Northern flying squirrels are also a little darker in color.
Ground squirrels live in… the ground! This family of species includes marmots, prairie dogs, groundhogs, and chipmunks. They burrow in hidden holes in the ground and live in a broader community than other species. Squirrels that often rise up on their hind legs are most likely ground squirrels.
They breed in the early spring.
Besides Red squirrels, most species do not compete for territory. If there is enough food in a given area, they are happy to live nearby, even sharing space with other species. If you enjoy watching the squirrels, you can encourage them to live in your yard and grow their population with specially made squirrel feeders . It might be fun to see how many varieties of squirrels you can attract.
Squirrel Gestation Periods and Habits
A squirrel gestation period (the time that they are pregnant) lasts less than a month to a month and a half. An Eastern gray squirrel’s gestation period is 44 days; an American red’s 40 days; a Fox squirrel’s 45 days; a Flying squirrel’s 40 days; and a Ground squirrel’s gestation period is 25-30 days.
During the squirrel’s gestation period, the female continues to find food for herself and maintain her nest. She will hide food away for the coming months while also eating enough for her growing babies and to build up her own nutrients for nursing them once they are born.
She will be very busy as the male squirrels do not assist her. Though squirrels are friendly with one another, they do not usually live in community. The exceptions to this rule are Ground squirrels, who are very communally oriented, and when squirrels choose to nest together for warmth. Even then, however, they do not share food resources. Each squirrel is expected to find their own. A female squirrel might also choose to build a new nest during this time if she deems her current location unsuitable or risky for young ones.
Squirrel Childbearing: Litter Size and Caring for Young
How many babies can a squirrel have? Most species have 3 or 4 babies at a time, but they could have as many as 9, and Ground squirrels could have up to 15 at one time!
Eastern gray squirrels give birth to their young in late winter or early spring and then again in July or August. They have anywhere from 2-9 babies in their nest. The babies will be pink with no fur, and their eyes will be closed.
The mother will keep them warm and nurse them for about 2 months before they are ready to start climbing and venture out of the nest. Even then, she will help them gather food for approximately one more month until they are ready to leave her and build their own nests. Once they leave in the spring, she will rest for a few weeks and then signal again that she is fertile. Males will chase her and the cycle will start again. Giving birth to a new litter in the summer months will allow her enough time to nurse them as they grow fur and become independent for the coming winter season.
American red squirrels have their babies in the nests in late spring or early summer. They usually have 3-6 babies at a time, but can have up to 8 in one litter. They also will nurse their babies for about two months and then might or might not have a second litter before winter. Red squirrels in northern states tend to not have another litter later in the year to better protect potential young from a harsh winter.
Their counterparts in southern states will have a second litter as the winters of their environment are less severe.
Fox squirrels give birth in the later part of February or during the first week of March. They can have 2-7 babies with most litters only being about 2-4 in number. They nurse their young in their nests for the typical 2-month period but then do not have another litter until the next year.
Flying squirrels have 2-7 babies twice per year. They bear the first litter in late spring or early summer and the second in early autumn. Most litters are made up of 2, 3, or 4 little ones that they will raise for two months.
Ground squirrels are the most prolific breeders. They usually have 7 or 8 babies at one time but can have as many as 15. Their numbers are controlled by the fact that they only breed once per year in late winter or early spring.
Baby squirrels are utterly helpless during the first 4-6 weeks of their life.
The mother will spend her time nursing them every 3-4 hours, grooming them, keeping them warm, gathering her own food, and ensuring that the nest is safe from predators and human activity. She will often build a second nest in case of danger and carry the young one by one to a new location if she senses a problem.
How Many Babies Can a Squirrel Have?
A squirrel reaches sexual maturity at 10-12 months. At this age, the males and females are fertile and can begin mating. A female, however, will not have more than one litter the first year of her adult life. When she is two years old, a female will have two litters per year if her species follows a semi-annual breeding pattern.
Squirrels typically live 2-3 years but can live up to 10 years. If a female squirrel has an average of 3 babies at a time, twice per year except for the first year, that means that each squirrel will have 6-54 babies in her lifetime. Fox squirrels and American red squirrels that only breed once per year will have half this many (3-27).
Ground squirrels could have 7-80 based on their average litter size. That’s a lot of squirrels!
Facts:
To sum up what we’ve learned, here are some general facts to remember.
- Squirrels breed once or twice per year.
- They mate in the early spring, and some breed again in the summer.
- Squirrels are pregnant for 25-45 days.
- They have their babies in nests in trees or in holes in the ground.
- The babies do not have any fur, can’t open their open eyes, and can walk for about a month.
- The mother takes care of the baby squirrels by herself for three months.
- Female squirrels have one litter their first year and usually two after that for up to 10 years.
- Most squirrels have 3 or 4 babies at a time, but Ground squirrels have 7 or 8.
When squirrels have babies
Have you ever seen two squirrels chasing each other in your yard or trees? They don't just play; they flirt! Male squirrels chase females to mate with them, after which the females will give birth to 2-8 cubs.
Squirrel mating: mother seduces, father pursues
When a female squirrel is about a year old, and it gets warm from winter to spring, she begins to secrete certain pheromones and make chirping sounds. These smells and sounds attract male squirrels and warn them that the female is fertile. Males are fertile all year round, but females only once or twice a year, so males get very excited when they hear and smell a female ready to produce offspring. nine0003
Males in the area will search for a female and then chase her to get a chance to mate with her. If two men are chasing her at the same time, they will fight each other for a chance. Older male squirrels are usually larger and therefore will win a fight with younger males. Most squirrels, with the exception of red squirrels, are not territorial, so this is the only time they will act aggressively towards each other. However, even in this case, the proteins do not injure each other. They simply stalk and try to intimidate each other until one of them complies and flees the scene.

Once the male catches up with the female and is able to mate quietly with the female (mating only takes about a minute), he ends up ejaculating a wax plug into the female's vagina. This plug prevents other males from fertilizing her, although this can fail and one litter can be produced by multiple fathers.
The female will continue to attract males with her pheromones and chirping for about two weeks to make sure she is pregnant. After a male has mated with her, he may return to her to mate again, but will not bond with her during or after her pregnancy. He has no other role than to mate with her in order to produce offspring. nine0003
It is very important that females produce these pheromones and vocalizations because squirrels are color blind. They see everything in shades of black, white and gray, and squirrels don't mate with other squirrels. The eastern gray squirrel does not mate with the American red squirrel, and the northern flying squirrel does not mate with the fox squirrel.
They rely on scent, sound, size, and fur markings to help them recognize and mate with their own species.
Mating seasons of squirrels
nine0002 The five most common squirrels in America are the Eastern Grey, American Red, Red Fox, Northern Flying, Southern Flying, and Ground Squirrel. You can identify each by face, and they each have slightly different mating habits. Oriental gray squirrels gray or silver with white belly. They are about 18-20 inches long including the tail. Some are all white (albinos) and others are all black. They are common in the eastern United States, that is, east of the Mississippi River. They love to live in walnut trees and build their nests of twigs and other materials on tree branches or in hollow tree trunks. They will deal with holes made by a woodpecker or damaged areas where a tree branch has fallen off if it is high enough off the ground to protect them from foxes, coyotes, snakes and other predators. The ideal height for a squirrel nest is 40-60 feet above the ground.
Eastern gray squirrels usually breed in late winter or early spring and then again in midsummer. nine0003
American Red Squirrels can be found throughout the United States. They are smaller than gray squirrels, about 9-10 inches long, with reddish-brown fur and a white underbelly. In winter, they grow tufts of fur on their ears and like to nest in coniferous (evergreen) trees rather than deciduous trees. You can also tell if there are red squirrels in your area by finding a large stash of nuts hidden in a hollowed out log or in the ground. Nuts are hidden not one at a time, but in a large pile. They will also drive other squirrels out of their territory, even if the other squirrels are larger. They mate twice a year in late winter and midsummer, but females are fertile for only one day during the breeding season. The male who mates with her will do this several times in a row to ensure she gets pregnant one day. nine0003
Fox squirrels are very similar to gray squirrels but have spread from the eastern states to the central states.
The difference in appearance is that foxes have reddish-gray fur with an orange belly. Most often they mate in January and bring only one litter per year.
flying squirrels are nocturnal while others are active during the day. They are 8-10 inches long, the same size as red squirrels, and have greyish-brown fur with a white underside. You can find out if you have squirrels by tapping the tree trunks with a stick. Sleeping fliers will stick their heads out of nests to see what's wrong and determine if they need to escape to a safer place. Southern flying squirrels breed in late winter or early spring, and then again during the summer months. Squirrels of the northern variety reproduce only in the first period. You can tell the difference between the two because the southern fliers live in deciduous trees while the northern fliers live in conifers.

Gophers live... in the ground! This family of species includes marmots, prairie dogs, marmots, and chipmunks.
They burrow into hidden holes in the ground and live in a wider community than other species. Squirrels that often rear up on their hind legs are most likely ground squirrels. They breed in early spring.
With the exception of red squirrels, most species do not fight for territory. If there is enough food in an area, they are happy to live nearby, even sharing space with other species. If you enjoy watching squirrels, you can encourage them to settle in your yard and increase their population with specially made squirrel feeders. It would be interesting to see how many varieties of squirrels you can attract. nine0003
Pregnancy periods and squirrel habits
The gestation period (the time they are pregnant) lasts from one to one and a half months. The eastern gray squirrel's gestation period is 44 days; 40 days american redhead; 45 days of chanterelle; 40 days flying squirrel; Gopher pregnancy is 25-30 days.
During the gestation period, the female continues to find food for herself and maintain her nest.
She will hide food for the coming months, as well as eat enough for her growing children and store her own nutrients to feed them after they are born. She will be very busy, as the males do not help her. Although squirrels are friendly with each other, they do not usually live in a community. An exception to this rule are ground squirrels, which are very socially oriented, and where squirrels prefer to nest together to keep warm. However, even in this case, they do not share food resources. Each squirrel is expected to find its food. The female squirrel may also build a new nest during this time if she considers her current location unsuitable or dangerous for the young. nine0003
Squirrel birth: litter size and pup care
How many babies can a squirrel give birth to? Most species have 3 or 4 babies at a time, but they can have up to 9, and gophers can have up to 15 at a time!
Eastern Gray Squirrels give birth in late winter or early spring and then again in July or August.
They have from 2 to 9 cubs in the nest. Babies will be pink with no hair and their eyes will be closed. The mother will keep them warm and feed them for about 2 months before they are ready to start climbing and exit the nest. Even so, she will help them gather food for another month or so until they are ready to leave and build their own nests. Once they leave in the spring, she will rest for a few weeks and then signal again that she is fertile. The males will chase her and the cycle will start again. Having a new litter during the summer months will give her enough time to nurse them while they grow their coat and become independent in the upcoming winter season. nine0003
American squirrels give birth in nests in late spring or early summer. They usually have 3 to 6 cubs at a time, but up to 8 cubs can be born in one litter. They will also nurse their babies for about two months and then may or may not have a second litter until winter. Squirrels in northern states tend not to have another litter later in the year to better protect potential young from the harsh winter.
Their counterparts from the southern states will have a second litter, as winters are less severe in their environment. nine0003
Fox squirrels give birth at the end of February or during the first week of March. They can have 2-7 cubs, while most litters have only 2-4 offspring. They nurse their young in nests for a typical two-month period, but then don't have another litter until the next year.
Twice a year flying squirrels give birth to 2-7 cubs. They carry the first litter in late spring or early summer, and the second in early autumn. Most litters consist of 2, 3 or 4 babies, which they will raise within two months. nine0003
Gophers are the most prolific breeders. They usually have 7 or 8 young at a time, but can have up to 15. Their number is controlled by the fact that they only breed once a year in late winter or early spring.
Squirrels are completely helpless during the first 4-6 weeks of their lives.
The mother will feed them every 3-4 hours, grooming them, keeping them warm, foraging for their own food, and making sure the nest is safe from predators and human activity. She often builds a second nest in case of danger and moves the young one by one to a new location if she feels a problem. nine0003
How many babies can a squirrel have?
Squirrel reaches sexual maturity at 10-12 months. At this age, males and females are fertile and can start mating. However, a female in her first year of adulthood will not have more than one litter.

Fox squirrels and American red squirrels, which only breed once a year, will have half that number (3–27).
Gophers could have 7-80 individuals depending on the average litter size. That's a lot of protein! nine0003

Residents of Novosibirsk rescue baby squirrels who are less than a month old
Everything is fine with the squirrels now.

Siberian Yelena Ermakova rescues two baby squirrels abandoned by her mother. The dramatic story took place in front of passers-by.
Siberians rescued little baby squirrels that were thrown out of the nest by their mother
— Squirrel threw all her baby squirrels out of the nest. They fell from a great height in different directions, - says eyewitness Victoria. “My sister caught one of the survivors right in the umbrella. The squirrel was inadequate. My sister and I took the babies to work with us. nine0003
And then the girls gave the babies to someone who knows a lot about squirrels. Elena Ermakova has been keeping a tame squirrel in her apartment for several years, named her Sonya and even started a page on Instagram for her pet.
- One squirrel only got a bruise, the second one was softened by an umbrella. All is well with them now. We feed the kids, take care of them. By the way, this is a girl and a boy,” says Elena.
The squirrels have no contact with the hostess's favorite, the squirrel Sonya.
There is a possibility that the crumbs born in the wild have fleas. While the cubs only sleep and feed on milk. Although one of them is already showing his character:
Babies are now syringe fed. Photo: https://www.instagram.com/squirrel_sonya/
“When you feed him with a syringe, he is picky and refuses,” says the Siberian.
Social media users were inspired by the cubs' story. Many were surprised by their mother's behavior:
— It's strange that this happens in nature. Such little ones, commentators write.
— This is how they get rid of sick or bad-smelling babies. Some kind of built-in instinct. But when loving people nurse such “miscarriages”, healthy squirrels grow out of them and often become tame. nine0003
- Poor kids! It's good that they have such wonderful saviors, and finally an adequate mom has appeared!
Recall that recently Elena Ermakova nursed another squirrel, which also fell out of the nest. Now he is in Tomsk, with a new family, it is interesting that the baby made friends with domestic cats.
