Merriams chipmunk

Merriam's chipmunk (Neotamias merriami) is a species of chipmunk in the Sciuridae family, found in central and southern California, as well as a small area in northern Baja California, Mexico. Its fur is grayish-brown with dark and light dorsal stripes, along with light gray or white eye stripes and a white underbelly. The tail is bushy and can measure over 80% of the head and body length. This species experiences molting and has a dental formula of 1.0.2.3.1.0.1.3 × 2 = 22.

Merriam's chipmunk inhabits forests and chaparral-covered shrublands, particularly along the western slope of the Sierra Nevada mountains. It is most commonly found at elevations under 1,200 meters, though it can be observed up to 2,940 meters. The species utilizes trees, shrubs, logs, rocks, and plant litter for food and shelter.

The diet of Merriam's chipmunk is herbivorous, focusing on seeds, nuts, berries, acorns (especially from valley oak trees), insects, and larvae. It forages daily and stores food in its cheek pouches for caching.

Reproduction involves females attracting males through calls lasting 10 to 15 minutes. Males respond by running and jumping around the female; after she squats, mating occurs with 12-24 thrusts, lasting about 15 seconds.
