Named for Frederick William Beechey, who explored much of Northern California in 1826-28 as captain of His Majesty's Ship Blossom, this squirrel is also sometimes called the Beechey Ground Squirrel. Description: Gray, light brown and dusky fur are mixed to give the California Ground Squirrel's upperparts a mottled appearance. A band of slightly darker fur, flecked with light gray, extends from the head over the middle of the back. Gray fur forms a cape over the sides of the head and shoulders. This gray cape may have a protective function, breaking up the animal's body outline and making it more difficult for a predator to spot. Light buff or grayish yellow fur covers the undersides. Whitish fur rings the eyes and perhaps protects the squirrel's eyes from too intense sunlight. Black fur edges the outer rims of the ears. The tail, five to seven inches long and more than half the length of the head and body, is covered with mixed yellowish gray and black hairs and is lighter on the underside. Generally, California Ground Squirrels measure between sixteen and nineteen inches total length. Habits: California Ground Squirrels live in burrows. Hillsides or low earth banks are preferred sites because the burrows can be excavated horizontally, although many burrows are dug down vertically several feet to assure protection. Burrows, which are about four or five inches in diameter, may vary in length from five feet to more than thirty-five feet and may be used by many generations of ground squirrels. Some burrows house single squirrel occupants, while others may be colonial homes for several squirrels. Short burrows many have a single opening, but longer branched burrows often have two or more openings. In studying California Ground Squirrels, one group of scientists found a squirrel home with six females and five males which consisted of tunnels totaling 741 feet in length and had thrity-three openings. The deepest tunnel was twenty-eight feet below ground. Although mo
