Have you ever seen a grey squirrel dash up a tree or leap from branch to branch and wondered—do they live alone or have families? The truth is, there’s a whole hidden world behind that fluffy tail. Grey squirrels may seem like solo adventurers, but their family life is full of surprises.
In this guide, we’ll explore the social lives of grey squirrels, how they find mates, where they raise their babies, and what happens when the little ones grow up. From the first chase to the final goodbye, let’s follow the full journey of a grey squirrel family.
The Foundation: Grey Squirrel Social Structure
Most people think squirrels are loners—but that’s not totally true. Grey squirrels are territorial and don’t form packs, but they aren’t completely isolated either. In areas with lots of food, they can tolerate each other and even show playful or warning behaviors. They use tail flicks, chirps, and scent markings to communicate.

The Mating Game: Courtship and Reproduction
The Energetic Mating Chase
When it’s mating season, male squirrels get very active. You might see them darting across trees in a big chase. Several males will try to impress one female by chasing her high into the treetops. This chase shows off their speed, strength, and agility.
When Do Grey Squirrels Have Babies?
Grey squirrels usually have babies twice a year: once in late winter (January–February) and again in mid-summer (June–July). This timing helps make sure the babies are born when food is easier to find.

Do Grey Squirrels Mate for Life?
Nope! Grey squirrels are not monogamous. They follow a polygynous system—meaning males and females mate with multiple partners. The males don’t stick around once mating is done.
Building a Home: The Squirrel Nursery (The Drey)
Once a female is pregnant, she starts preparing her nest, called a drey. This is usually a round ball of leaves and twigs built high in the trees. In winter or before babies arrive, the mother makes it extra warm with moss, shredded bark, and grass. Dreys are sturdy and protect the babies from wind and rain.

The Mother’s Role: A Dedicated Single Parent
After giving birth, the mother takes full charge. The male plays no part. She nurses the babies, keeps them warm, and guards the nest. If danger comes, she will fight off predators to protect her kits.
What a Litter of Squirrel Kits Looks Like
When baby squirrels are born, they are blind, hairless, and tiny. They can’t survive without their mom. Most litters have 2–4 kits. These early days are all about nursing and staying warm.

Growing Up Fast: The Life of a Young Squirrel
Developmental Milestones: From Birth to Branching
- 3–4 Weeks: Fur starts to grow.
- 5 Weeks: Their eyes open.
- 7–8 Weeks: They begin to explore outside the nest. This is called “branching.”
- 10–12 Weeks: They are fully weaned and start learning how to find food.
Learning the Ropes: Lessons from Mom
Mom teaches her babies how to survive. She shows them how to find nuts, crack them open, build a nest, and hide from predators. These skills help them live on their own.

Leaving the Nest: Dispersal and Independence
At around 12 weeks old, young squirrels leave the nest. This is called dispersal. They go off to find their own territory. It’s a risky time—many young squirrels don’t survive their first year due to predators or starvation.

Grey Squirrel Family FAQ
A group of squirrels is called a “scurry” or “dray.” But in real life, squirrel families usually mean a mom and her babies.
No. Male squirrels don’t take care of the young. That job belongs only to the mother.
Baby squirrels usually stay with their mom for 10 to 12 weeks before going off on their own.
A Mother’s Fleeting Legacy
Grey squirrel families don’t last forever. They’re built around one strong, hardworking mom and her babies. In just a few months, the little ones grow up and move away. But during that short time, the mother gives them everything they need to survive.
So next time you see a grey squirrel in your yard, remember—there’s a lot more to her story than meets the eye.
