Least chipmunks are smaller (7-9 inches) with a more slender tail and extra white on the face. The simplest clue: if it looks like a typical chipmunk, it's eastern.

What habitats do chipmunks prefer in New Jersey?
Both types favor deciduous forests, rocky areas, and woodland edges. Eastern chipmunks adapt well to suburban gardens, stone walls, and parks. Least chipmunks stick to more remote, rocky slopes. Look for them near fallen logs, brush piles, and stone fences.
What are some common behaviors to help identify chipmunks?
Chipmunks are known for stuffing their cheeks with food and giving sharp, bird-like alarm calls. They often sit upright on rocks or logs. Eastern chipmunks are bolder around people, while least chipmunks tend to be more secretive. Watch for their fast, darting movements between cover.
