Squirrels are omnivores–they eat seeds, nuts, leaves, bulbs, roots, mushrooms, insects, worms, eggs, small birds, and other small animals. They are rodents that have hairy tails and strong hind legs; there are over 350 species of squirrels worldwide.In the eastern U.S. and adjacent Canada the common "park squirrel" is the eastern gray squirrel. All members of the squirrel family except the flying squirrels are diurnal, which means they are active during the day–this is rare among wild mammals!

Squirrels are considered pests when they enter homes and buildings to nest; when they raid birdfeeders; when they feed on gardens, trees and landscape plantings; and when they dig holes in gardens and lawns to bury and retrieve food.
