You’ll spot squirrels most often in the early morning and late afternoon. They don’t really stick to a strict bedtime like humans do. Squirrels stay active during the day, sleeping in short bursts and napping between quick bouts of foraging and play. If you know this, you can usually guess when they’ll dart past your yard or curl up in a nest.
As you read on, you’ll see how their daily routines shift with food, weather, and safety. Squirrels pick their sleeping spots based on warmth and quiet, and honestly, it’s pretty interesting to watch those choices play out.
When Do Squirrels Sleep?
Squirrels sleep at different times depending on which kind they are, the weather, and their age. You’ll find out when they rest each day and how their routines change with night, day, and cold weather.
Squirrel Sleep Patterns and Daily Routines
Most tree squirrels, like gray and red squirrels, get busy during daylight hours. You’ll catch them foraging in the morning and again in the late afternoon.
They take quick naps between feeding trips, heading back to a drey or tree hollow to rest. Flying squirrels flip the script—they come out at night, leaving tree cavities after dusk to hunt for food.
Ground squirrels spend a lot of time resting in burrows. They pop out to forage when it feels safe.
Squirrels break up their sleep into lots of short naps, not one big chunk. They rack up about 10–15 hours of sleep a day, but baby squirrels sleep way more.
Adults save energy by staying still in safe spots when it’s too hot or cold outside.
Nighttime vs. Daytime Sleep Habits
If you look outside at night, you probably won’t see tree squirrels moving around. They tuck themselves into dreys or tree cavities, curling their tails over their bodies and staying on alert for danger.
Flying squirrels, though, use the dark to forage and sleep in cavities during the day. When the midday sun gets too bright, most squirrels chill out in shaded nests or hollows to dodge heat and predators.
Ground squirrels often slip underground during dangerous or hot hours. Burrows keep them cool and hidden.
Squirrels wake up a lot, always checking for food or threats. Their sleep stays pretty light and breaks easily if there’s noise or sudden movement.
You might spot them sitting upright and frozen before they dash off—that’s their mix of resting and staying vigilant.
Seasonal Changes and Torpor
Squirrels shift their sleep habits with the seasons. In winter, tree and flying squirrels slow down and sometimes stay in nests for days if it’s freezing out.
They enter a lighter state called torpor, dropping their heart rate to save energy. Ground squirrels go even further and hibernate.
They hole up in burrows for months, letting their body temperature and metabolism drop way down. The hibernation stretch depends on the species and where you live.
Torpor doesn’t last forever. On mild winter days, squirrels will leave the drey to grab some food.
When it gets really cold, several flying squirrels or tree squirrels might share a cavity to keep warm. Communal nesting isn’t rare in winter.
Baby Squirrels: Sleep Needs and Schedules
Baby tree squirrels—kits—sleep a ton. When they’re tiny, they can sleep up to 20–22 hours a day.
Their mom keeps them cozy in a drey or cavity and comes back often to feed them. You’ll usually find kits snuggled together for warmth and safety.
As they grow, kits wake up more often to nurse and start moving around. After a few weeks, they have short, active spurts and begin exploring the nest.
Their sleep patterns slowly shift toward what adults do over several months.
If you ever care for orphaned or rescued baby squirrels, you’ll need to feed them often and keep their nest warm.
Their sleep is crucial for growth, so caretakers follow strict routines until the young ones are ready to handle things on their own.
Where and How Squirrels Sleep
Squirrels pick specific places and materials to stay warm, hide from predators, and raise their young. You’ll spot them in nests made of twigs and leaves, tree cavities lined with soft stuff, or underground burrows—depends on the species and time of year.
Tree Squirrels and Dreys
Tree squirrels build round nests called dreys in branch forks or thick foliage. A typical drey is about basketball-sized, with a twig frame lined with leaves, moss, and shredded bark to hold in heat.
You’ll often see dreys high up in oak, maple, or pine trees where branches meet. Dreys shield squirrels from wind and light rain, but heavy storms can be a problem.
Mother squirrels use dreys for raising kits. You might spot them carrying fur and leaves into the nest during spring.
Tree squirrels usually stay active by day and head back to dreys at night or when the weather turns cold.
Squirrels Sleeping in Trees and Leaf Nests
Some squirrels skip dreys and use tree cavities instead. Cavities show up in older trees or after woodpeckers have been around.
Inside, squirrels line the hollow with fur, leaves, and feathers for extra warmth. Flying squirrels really like cavities, and sometimes they’ll sleep together to save heat.
Leaf nests on branches do the same job as dreys but look a bit messier and more leafy. If you spot holes or gaps in a tree trunk, there’s probably a cavity there.
Check out high branches where leaves stay thick—squirrels go for sheltered spots that block wind and hide them from hawks and other predators.
Ground Squirrels and Burrow Habits
Ground squirrels dig burrow systems into soil, rocky banks, or open fields. Burrows usually have several entrances, nesting rooms, and even spots to stash food.
You’ll see California ground squirrels and others using tunnels 2–4 feet deep to dodge cold and stay safe from predators.
Burrows help ground squirrels hibernate or go into long torpor during winter. While hibernating, their body temperature and heart rate drop way down to save energy.
You’re most likely to see ground squirrel action from spring through fall when they come out to forage and tidy up their burrow entrances.
Squirrel Sleeping Locations in Bad Weather
When heavy rain, snow, or strong winds roll in, squirrels look for the driest, warmest spot they can find.
Tree squirrels usually stay inside their dreys, or sometimes they rush into hollow trunks as storms approach.
You might catch a squirrel curling its tail over its back, trying to shed water during a quick shower.
Ground squirrels dive deep into their burrows when the weather gets rough.
Flying squirrels—and even some tree squirrels—will squeeze together in cavities or dreys to huddle and keep warm.
If food runs low, squirrels might just stay curled up in their nests for longer stretches, barely venturing out at all.
