What is a "squirrel"?

Squirrels are small to medium-sized rodents known for their bushy tails, sharp teeth, and excellent climbing abilities. They are found in various parts of the world, including North America, Europe, Asia, and Africa. Squirrels have a slender body with a long, fluffy tail that they use for balance and communication. They have large eyes and ears, and their fur can vary in color depending on the species. Squirrels are known for their acrobatic and agile movements, often seen running and leaping through trees, and easily navigating branches and obstacles. They primarily feed on nuts, seeds, fruits, and sometimes insects, and are known for their ability to cache food, burying it in various locations to retrieve later. Squirrels are diurnal animals, meaning they are active during the day, and may live in nests called dreys or in tree hollows, depending on the species. They are known for their chattering vocalizations and can be highly territorial.
