Squirrels are members of the family Sciuridae (/sɪˈjuːrɪdeɪ, -diː/), a family that includes small or medium-sized rodents. The squirrel family includes tree squirrels, ground squirrels (including chipmunks and prairie dogs, among others), and flying squirrels. Squirrels are indigenous to the Americas, Eurasia, and Africa, and were introduced by humans to Australia. The earliest known fossilized squirrels date from the Eocene epoch, and among other living rodent families, the squirrels are most closely related to the mountain beaver and dormice.

Squirrels in the context of Red Rock Canyon State Park (California)
Red Rock Canyon State Park is a state park in the U.S. state of California which features scenic desert cliffs, buttes and spectacular rock formations. The park consists of approximately 27,000 acres (110 km) within the Mojave Sector of the Tehachapi District of the California State Park System, and is located along State Highway 14 in Kern County, about 80 miles (129 km) east of Bakersfield and 25 miles (40 km) north of Mojave, where the southernmost tip of the Sierra Nevada converges with the El Paso Mountains.
Each tributary canyon is unique, with vivid colors due to alternate layers of white clay and red sandstone, further accented by pink volcanic rocks and brown lava formations. The canyon was formed 3 million years ago. After wet winters, the park's floral displays are notable. Three overlapping desert ecosystems provide for the wildlife that includes eagles, falcons, roadrunners, hawks, coyotes, kit foxes, bobcats, lizards, mice and squirrels. Red Rock Canyon provides magnificent views of the pristine desert landscape, includes two natural preserves, and offers, among other recreational activities, camping, sightseeing, equestrian activities, hiking, and opportunities for solitude.
Squirrels in the context of Scavenger
Scavengers are animals that feed on dead and decaying organic matter. Often the term is used to describe the consumption of carrion, the bodies of animals that have died from causes other than predation or the bodies of animals that have been killed by other predators. However, the term is also used to describe animals that feed on rotting plant matter or refuse.
Vultures and burying beetles are examples of scavengers that feed on carrion, pink bud moth and stag beetle larvae are examples of scavengers that feed on rotting plant matter, and raccoons and squirrels are examples of scavengers that feed on refuse. Carrion-eating scavengers are called necrophages.
