Ever wondered where you’ll find the most squirrels, and what makes those spots so perfect for them? Cities and suburbs with lots of trees and reliable food—especially parks with old oaks—tend to draw the biggest squirrel crowds.
Let’s look at which regions and neighborhoods overflow with squirrels, and why. You’ll get real examples, side-by-side comparisons, and some reasons you can actually spot just by taking a walk outside.
Where Are the Most Squirrels Found?
Some U.S. states and world regions just have way more squirrels, and sometimes the squirrel-to-human ratio gets downright funny.
States and Regions with Highest Squirrel Populations
Across the U.S., states with big forests and a mix of cities and suburbs seem to win the squirrel sweepstakes. Oregon and Washington have all sorts of species, including the western gray squirrel and Douglas squirrel.
Michigan, Minnesota, and Wisconsin report lots of american red squirrels (Tamiasciurus hudsonicus) and northern flying squirrels (Glaucomys sabrinus). Tree squirrels like the eastern gray squirrel (Sciurus carolinensis) and fox squirrel (Sciurus niger) show up on most state lists.
California’s got both the california ground squirrel (Spermophilus beecheyi) and Humboldt’s flying squirrel. You’ll find the most species where forests, parks, and suburbs all meet up.
Global Squirrel Hotspots
Squirrels seem to love temperate forests in North America and Eurasia, and they do pretty well in tropical Asian forests too. You’ll spot tons of species where trees and food—nuts, seeds, you name it—are everywhere.
Regions with a mix of woods and human greenspaces, like parks and suburban yards, support big local squirrel numbers.
Head to temperate North America and you’ll run into gray squirrels, fox squirrels, and flying squirrels (Glaucomys volans, Glaucomys sabrinus). In Eurasia and Asia, you’ll see their local cousins—tree and ground squirrels that fit the local forest.

Squirrel-to-Human Ratios: Unique Cases
Some college campuses and small towns have more squirrels than people, at least during the day. You might notice eastern gray squirrels everywhere on campus lawns, or see rural towns packed with american red squirrels or fox squirrels compared to the number of humans.
When there’s plenty of food and not many predators, squirrel numbers just explode. High counts pop up near bird feeders, park picnic spots, and big old oaks loaded with acorns.
Species matter too—flying squirrels are sneaky and stay hidden at night, while the eastern gray squirrel is out and about, making the numbers seem even higher. For a deep dive into state-level counts, here’s a handy table: squirrel population by state.
Why Certain Places Have More Squirrels
You’ll see more squirrels where food, shelter, and not too many predators all come together. Climate, tree types, and what people do with their land make a big difference.
Habitat and Environmental Factors
Squirrels really just need three things: shelter (trees or burrows), food, and a safe spot to raise their babies. In forests with lots of oaks, pines, or nut trees, tree squirrels like the red squirrel and Eurasian red squirrel find plenty to eat and lots of places to nest.
Ground squirrels, like the European ground squirrel (Spermophilus citellus), go for open grasslands or steppe with soft soil for digging.
Rain and temperature play a role too. Mild winters and long growing seasons mean more seeds and fruit, so squirrel numbers go up. Tough winters or droughts cut down food and survival.
Soil type matters for ground squirrels—they need stable burrows. Tall, connected tree canopies let tree squirrels move around and dodge predators.
Urban Versus Rural Squirrel Abundance
In cities, you might actually spot more tree squirrels than in the countryside, depending on the local parks and gardens. Urban areas offer easy food—think bird feeders, trash, or people tossing nuts—and lots of planted trees for nesting.
You’ll often see eastern gray squirrels or Indian palm squirrels near homes and parks where folks feed birds or leave snacks out.
Rural and wild areas usually have more squirrel species, including ground squirrels and chipmunks. On the edges of farmland, ground squirrels sometimes take over crop fields and hedgerows.
Cities can pump up squirrel density, but rural woods and grasslands tend to have more types of squirrels overall.
Species Adaptation and Distribution
Different squirrels have their own tricks. Tree squirrels stick to branches and tree hollows. Flying squirrels glide between trees at night and love mature forests.
Ground squirrels dig deep burrows and live in colonies. Chipmunks go for smaller burrows and stuff their cheeks with seeds.
Some squirrels move into new places when people plant the right trees or chase off predators. The Indian palm squirrel (Funambulus palmarum) does great in South Asian cities and gardens.
Three-striped palm squirrels also fit right into landscaped areas. When you see lots of one species, it usually means the local food and shelter suit them perfectly.
Unique Squirrel Species Around the World
You’ll spot squirrel species on every continent except Antarctica and Australia. In North America, tree squirrels and chipmunks show up all over mixed forests.
Europe has the Eurasian red squirrel in its woodlands. You’ll also find the European ground squirrel in those wide, grassy areas.
Asia’s got a bunch of tree and palm squirrels, like the Indian palm squirrel and the three-striped palm squirrel. It’s honestly surprising just how many different types are out there.
Flying squirrels make their homes in forests with tall trees across Asia, Europe, and North America. Ground species like Spermophilus citellus hang out in open steppes and meadows in parts of Europe and Asia.
Curious about which squirrels live near you? Try checking your local park lists or wildlife guides—they’ll mention species like tree squirrels, ground squirrels, flying squirrels, red squirrels, and chipmunks.
