Merriam's chipmunk

Merriam's chipmunk is a chipmunk of the squirrel family found in central and southern California, including the western slope of the Sierra Nevada, and in a small area of northern Baja California in Mexico. It has grayish-brown fur with dark and light dorsal stripes, light gray or white stripes around the eyes, a white underbelly and a very bushy tail that often measures over 80 percent of the length of the head and body. It lives mainly in forest and chaparral-covered shrubland, most often below about 1,200 meters though it has been seen as high as 2,940 meters, and it depends on understory brush, trees, rocks, logs and plant litter for food and shelter. The diet is mainly herbivorous: acorns are a major food, especially from valley oaks, and the chipmunk carries seeds and acorns in its cheek pouches to cache them in the ground, while also taking berries, insects and larvae. Females call to attract males when mating.
