Squirrels are small to medium-sized mammals found in forests, grasslands, parks, gardens, and even busy neighborhoods. They are known for their bushy tails, quick movements, climbing skills, and habit of storing food. From tree squirrels and ground squirrels to flying squirrels, each type has unique features, habitats, and behaviors that make it interesting to learn about.
1. Eastern Gray Squirrel
The Eastern Gray Squirrel is one of the most common and recognizable squirrels in North America. Known for its bushy tail, quick movements, and strong climbing ability, this squirrel is often seen in parks, forests, gardens, and neighborhoods. It plays an important role in spreading tree seeds and helping forests grow naturally.
Characteristics

Habitat
This squirrel lives in hardwood forests, city parks, suburban yards, and areas with many trees. It prefers places where oak, walnut, maple, and hickory trees are available because these trees provide food and nesting sites. In urban areas, it easily adapts to human surroundings and may nest in tree cavities or leafy nests.
Diet and Behavior
Eastern Gray Squirrels mainly eat nuts, seeds, berries, fruits, buds, and fungi. They are famous for burying nuts in the ground and returning later to eat them. However, they do not find every buried nut, which allows many seeds to grow into new trees. They are quick, alert animals and often use their tails to communicate warnings.
