All over Virginia it's a common sight to see squirrels foraging for acorns in the fall. The gray squirrel is primarily herbivorous, but it will also eat insects, eggs and young birds, making it more omnivorous than the fox squirrel.
Squirrels commonly cache food, especially nuts, for future use.
The gray squirrel can eat approximately 100 pounds per year per individual and may bury 1000 nuts per year. It can also differentiate edible mushrooms from poisonous ones. Squirrels will move to a new location when the nut supply is exhausted. They obtain minerals from bones, antlers and turtle shells as well. Red squirrels are a species of upper elevations, so they are found only in the western, mountainous parts of the state in mixed hardwood forests.
