American Red Squirrel

Tamiasciurus hudsonicus

Also known as Pine Squirrel, Chickaree, Boomer, North American Red Squirrel

American red squirrels defend fiercely defined territories centered around massive piles of conifer cones called middens. Their energetic chitter-calls echo through the canopy, signaling boundaries to rivals and warning off potential intruders. Active year-round, these energetic rodents store thousands of green cones each autumn to survive harsh northern winters.

Responsible observation

  • Maintain Distance: Avoid cornering or attempting to feed wild squirrels to prevent defensive bites.
