GOLDEN CHIPMUNK
Callospermophilus lateralis chrysodeirus
EASTERN CHIPMUNK
Tamias striatus
Spermophiles are nearly circumpolar in distribution, ranging through northern lands from central Europe across Bering Strait to the Great Lakes in North America. Many species exist in North America, varying greatly in form, size, and color. They occur mainly in the western part of the continent from the Arctic coast of Alaska to the southern end of the Mexican table-land. Some species are represented by enormous numbers and do great injury to cultivated crops. Among the larger and best known of the injurious species, the California ground squirrel, with its several geographic races, occupies most of the Pacific coast region from Oregon to Lower California. It has a broad vertical distribution, extending from the seashore to about 10,000 feet altitude on the western slope of the Sierra Nevada in California, and thrives under contrasting climatic conditions, as the humid northwest coast region and the most arid deserts of Lower California.
