Found throughout Illinois, fox squirrels are a delightful sight to see scurrying through the trees. Here are some facts about their behavior and habitat:

  1. Fox squirrels are diurnal, meaning they’re most active during the day. They spend their time foraging for food, such as nuts, seeds, fruits, and insects.
  2. They’re also known for their impressive climbing and jumping abilities, which allow them to move quickly and easily through the trees.
  3. Fox squirrels tend to prefer forested areas with mature trees, but they can also be found in urban and suburban environments with abundant trees and green spaces.

In terms of habitat, fox squirrels are adaptable and can thrive in a variety of environments. They prefer areas with a mix of mature trees and open spaces, as this provides them with both food and shelter.

However, they can also be found in more urban environments, such as parks and residential areas, as long as there are sufficient trees and green spaces available.

Overall, fox squirrels are a fascinating and important species in Illinois’ ecosystem.

3. The Red Squirrel

One fascinating thing about red squirrels is their ability to store food for the winter. They’re known to hoard their winter food supply in multiple locations, called middens, which can contain up to 8,000 cones.

This behavior helps them survive the harsh winters in Illinois, where temperatures can drop below freezing.

Red squirrels prefer habitats with coniferous forests, where they can find their primary food source, pine seeds.

They’re also known to eat fungi, nuts, and fruit.

However, their populations in Illinois are threatened due to habitat loss and fragmentation. Conservation efforts have been put in place to protect their habitats and promote their survival.

These efforts include the creation of wildlife corridors and increasing public awareness about their importance in the ecosystem.

4. The Flying Squirrel

You’ll be amazed by the flying squirrel’s ability to glide from tree to tree with their specialized skin flaps, called patagia, that stretch from their front to hind legs.

These flaps help the squirrel glide effortlessly through the air, allowing them to cover distances of up to 150 feet. This glide mechanism is also incredibly precise, as the squirrel can control its direction and speed by adjusting its limbs and tail.

Flying squirrels are primarily nocturnal, meaning they’re most active at night. During the day, they rest in tree cavities or nests made from leaves and twigs.

Their diet consists of nuts, seeds, and insects, which they forage for at night. Despite their name, flying squirrels can’t actually fly, as they don’t have the ability to generate lift.

Instead, they glide through the air using their patagia and rely on their strong hind legs to land safely on the next tree.

Overall, the flying squirrel is a fascinating mammal with unique adaptations that allow it to thrive in the forests of Illinois.
