The western gray squirrel (Sciurus griseus) dwells in the forests of Western United States and can be found to an elevation of about 6,500 feet.
This rodent feeds mainly on seeds and roots (especially pine seeds and acorns) but will take berries, fruits, fungi, insects and tree buds. Western gray squirrels make food caches, but are inefficient at recovering their stashes, leaving many seeds to germinate.
Although western gray squirrels do not hibernate, they become less active in the winter.
As in these pictures, taken at North Mountain Park in Ashland OR, western gray squirrels spread their tails over their heads when alert.
