Read these fun and interesting Sonoma chipmunk facts about the species of mammals of the Pacific states.

Mammals comprise humans and other warm-blooded vertebrates with hair and fur. 40% of mammals are classified as rodents from the order Rodentia.

Among rodents are mice, rats, chipmunks, prairie dogs, squirrels, porcupines, guinea pigs, hamsters, and beavers.

The Neotamias sonomae or the Tamias sonomae, the Sonoma chipmunk, is yet another species of rodent from the genus Eutamias, specifically the genus Tamias or Neotamias. Sonoma chipmunks are further classified into two subspecies: the Tamias sonomae alleni and the Tamias sonomae sonomae.

They belong to the squirrel family of Sciuridae. The distribution range of Sonoma chipmunks is within Marin counties and Sonoma around the north of San Francisco Bay in California.

It is distantly related to the yellow-pine chipmunk and Townsend's chipmunk found within its geographic range.

This species classified as Neotamias, the subgenus of genus Tamias, is known to have two premolars.

While chipmunks are found living in burrows in the ground, the Sonoma chipmunk, in particular, is found within a precise range of its habitat including coniferous forests of redwood, black oak, spruce, douglas fir, pine, and laurel trees, and open, chaparral areas such as sagebrush plains.

Further, it has an omnivorous diet comprising seeds, nuts, berries, fruits, herbs, and buds of woody plants, insects, and eggs of birds. The Sonoma chipmunk, a member of the ground-dwelling squirrel family, has a cinnamon brown-gray fur with several black, brown, and white stripes running over its body with a long tail.

The species is known to have winter and summer fur as winter fur is duller and darker than its summer fur.

It was first documented in 1915 by an American zoologist and biologist, Joseph Grinnell. Yet, the species is not extensively studied.

If the uniqueness of a Sonoma chipmunk makes you interested in reading more about similar species, you can read about the chipmunk and the least chipmunk.
