Eli5: Why are there so many squirrels in cities?

634 views

I get why cities support crows, rats, raccoons, and other animals that eat our garbage, but squirrels don’t. What do cities offer squirrels?

In the 19th century grey squirrels were introduced in to US city parks and encouraged to thrive so that they would entertain visitors to the parks. Once a population was so established it was easy for them to survive as those parks also had plenty of nut trees.

Grey squirrels aren’t too fussy, they will happily eat some food scraps left by humans, which is one reason why they outcompete red squirrels

A city provides a smorgasbord of hiding places for both their food caches and their sleeping spaces.

Ever find a random pizza crust on your porch in a corner? Or my favorite was finding 2 walnuts on the kickstand of my bike.. That’s squirrels hiding food from other animals

Many of their natural predators are not big fans of humans and are not found in large quantities in cities. They still have access to their normal food source inside a city so their population size is larger.
