Squirrel Pictures
In the United States, squirrels blend easily into every type of landscape, from residential areas to forests to deserts. Discussions regarding the types of squirrels found in the United States often point to three general categories: Ground Squirrels; Tree Squirrels; Flying Squirrels.
Ground Squirrels, including prairie dogs and chipmunks, account for the vast majority of squirrel species. (56 of 66 documented species). Their practice of nesting in ground burrows accounts for their category name.
Most ground squirrels species spend their days foraging for food along the ground, however, some species are known to climb trees. Most people associate squirrel diets with nuts, however, all squirrels, including ground squirrels, eat a variety of foodstuffs including fruit, nuts, insects and mushrooms.
The California Ground Squirrel and Rock Squirrel are examples of the larger, bushy tailed species with mottled colored fur. The Golden-Mantled Squirrel and Harris' Antelope Squirrel are examples of some smaller, striped species.
Estimates vary, however, there are around ten different species of tree squirrels in the United States. They generally are medium sized squirrels that nest in tree cavities or limbs.
Gray Squirrels and Fox Squirrels rank among the most common tree squirrels found in residential areas across the United States. They are active year round, often visiting backyard bird feeders.
The Northern and Southern Flying Squirrels represent the Flying Squirrel genus (Glaucomys) in the United States. They are nocturnal mammals that nest in trees. Their ability to glide from tree to tree sets them apart from the other tree squirrel species.
