About the California Ground Squirrel
The California ground squirrel (Otospermophilus beecheyi), also known as the Beechey ground squirrel, is a common and easily observed ground squirrel of the western United States and the Baja California Peninsula. It is common in California with its range spanning through much of the state, as well as northeastern Nevada in areas around Reno and Lake Tahoe.
Formerly placed in Spermophilus, as Spermophilus beecheyi, it was reclassified in Otospermophilus in 2009, as it became clear that Spermophilus as previously defined was not a natural (monophyletic) group. John Richardson, who originally described the species as Arctomys (Spermophilus) beecheyi, or "Beechey's marmot", named it after Frederick William Beechey, an early 19th-century British explorer and naval officer. The squirrel's upper parts are mottled, with the fur containing a mixture of gray, light brown and dusky hairs. The shoulders, neck and sides are a lighter gray. The fur around the eyes is whitish. The underside is lighter, buff or grayish yellow. Head and body are about 30 cm (12 in) long and the tail an additional 15 centimetres (5.9 in). They can weigh from 280 to 738 g (9.9 to 26...
