Eastern Gray Squirrel

Sciurus carolinensis

Also known as Eastern Grey Squirrel, Gray Squirrel, Grey Squirrel

Eastern gray squirrels spend their days foraging among mature oak and hickory branches, relying on a bushy tail for balance and thermal insulation during cold winter months. Each autumn, individual squirrels scatter-hoard thousands of nuts, inadvertently planting vast numbers of hardwood trees that shape forest ecosystems. They communicate through sharp chatter calls and flicking tail signals to warn neighbors of approaching predators.

May bite or scratch if cornered or hand-fed; observe from a safe distance.
Responsible observation
  • Observe Quietly: Watch their arboreal acrobatics from a distance without sudden movements.
  • Avoid Hand Feeding: Offering food directly by hand encourages aggressive begging and risk of bites.
  • Spot Leaf Nests: Look for bulky leaf nests called dreys high in tree forks during late fall.
