Chipmunks of the Olympic Peninsula


Two chipmunk species live on the Olympic Peninsula: Townsend’s Chipmunk, Tamias townsendii, and the Olympic Chipmunk, Tamias amoenus caurinus, a Yellow-pine Chipmunk subspecies that is endemic to the Olympics.

While Townsend’s Chipmunk tends to live at lower elevations, they can be found at higher elevations as well. Olympic Chipmunks live at high elevations, and are common in the Hurricane Ridge area.

Our photographs here are organized by elevation: near sea level, around 2000 feet, and around 5000 feet. The ones near sea level are Townsend’s chipmunk. Our best guess is that the photos taken at around 2000 feet are of Townsend’s Chipmunk. The chipmunks photographed at around 5000 feet are likely Olympic Chipmunks but could possibly include some Townsend’s Chipmunks.

We have looked for, but have not found, a way to distinguish the two species in photographs. Townsend’s Chipmunk is larger than the Olympic Chipmunk but it is difficult to judge size in photographs (and even in the field). The sources we read describe the Olympic Chipmunk as having more brightly contrasting stripes. They also refer to the presence in Olympic Chipmunks of a dark stripe from nose to eye.
