California ground squirrels are often regarded as pests in gardens and parks, since they eat ornamental plants and trees. They commonly feed on seeds, such as oats, but also eat insects such as crickets and grasshoppers, as well as various fruits. [10] The dental formula of O. beecheyi is 1.0.2.3 1.0.1.3 × 2 = 22. [11]
They also eat seeds and insects (ants, termites, and grasshoppers). Most of their foods are chosen for high water content because of the shortage of available water in their environment. The average water content of the food they eat is 80%. [3] The squirrels prefer seeds and parts of grasses and flowers, but can climb into shrubs and trees for ...
