The Least Chipmunk, Tamias minimus, is perfectly named! This is a very small chipmunk, weighing only 32 to 50 grams with a total length of 185-216 mm. The Least Chipmunk loves to use its tail and will run with the tail straight up and flicker it back and forth while perching.
Chipmunks can be distinguished from other squirrels by their distinct striping through the eyes.
