Identifying chipmunks can be tricky! With their adorable cheeks and busy nature, these little rodents often leave us wondering: what chipmunk am I looking at? This guide will walk you through identifying the common chipmunk species found in North America.

Key Features for Chipmunk Identification

Before diving into specific species, let's cover some general features to look for:

Size and Shape: Chipmunks vary in size, from the petite least chipmunk to the larger eastern chipmunk. Note the overall body length and the relative size of the head, body, and tail.
Coloration: Look closely at the fur's base color and any stripes or markings. These patterns vary greatly between species and even within a species depending on location.
Tail: The tail's length, busyness (amount of fur), and coloration can be distinctive features.
Location: Knowing the geographic region where you saw the chipmunk significantly narrows down the possibilities.

Common North American Chipmunk Species

Here are some of the most frequently encountered chipmunk species in North America:

1. Eastern Chipmunk (Tamias striatus)
