Ground squirrel

Earely antelopes are seen, but wolves, rabbits, and sundry ground squirrels abound.

Many ground squirrels sit up and look like prairie dogs, but a ground squirrel can be recognized by its longer face and tall.

2003, University of California Agriculture and Natural Resources, Integrated Pest Management for Walnuts, UCANR Publication 3270, page 23, In some areas, ground squirrels may present a potential health problem because they carry ectoparasites that may transmit diseases such as bubonic plague to humans. The adult California ground squirrel has a head and body 9 to 11 inches (23-28 cm) long and a somewhat bushy tail that is about as long as the body.

Pocket gophers appear to be abundant in the APWRA on both sides of Altamont Pass Road, whereas ground squirrels appear to be abundant only on the north side.
