Squirrel | Facts, Diet, Habitat & Pictures

Squirrel Overview


Squirrels are small, agile mammals often seen in parks and forests. They have bushy tails that curve over their backs, which they use for balance and communication. Squirrel fur can range from gray and brown to reddish hues. Squirrels have sharp, curved claws for climbing trees and a keen sense of vision and smell.

Origins And Evolution

Squirrels are rodents that trace their origins back to the Eocene epoch, approximately 40 million years ago. They evolved from a common ancestor with the rat-like rodent group. Early squirrels were small and ground-dwelling, gradually developing adaptations for tree-dwelling life.

Their evolutionary path led to the development of distinctive features like their large, expressive eyes, sharp claws for climbing, and their signature long, bushy tails. These adaptations helped squirrels thrive in arboreal environments.

They spread across different continents, evolving into diverse species, such as tree squirrels, ground squirrels, and flying squirrels, each adapting to their specific habitats.

The evolutionary success of squirrels can be attributed to their ability to efficiently forage for nuts and seeds, which they store for winter survival. This adaptation, combined with their agility and clever behavior, has allowed them to become one of the most recognizable and adaptable mammal groups in the world.

Behavior and Lifestyle

They are renowned for their agile and acrobatic behavior, often seen leaping between trees and scampering up and down trunks with ease.  They are territorial animals, marking their territories with scent markings and engaging in vocal communication, such as chattering and barking, to defend their domains.
