Eastern Chipmunk

Tamias striatus

Also known as: Eastern American Chipmunk

LCLeast Concern

Eastern Chipmunk is a striped ground squirrel that stores food in expandable cheek pouches. It digs complex burrows, gathers nuts and seeds by day, and gives sharp alarm calls from cover. National records follow eastern woodland and suburban edges, while Texas lies near the southwestern edge of the range. National occurrence records reveal where and when people have documented it, but they don't measure abundance or prove that an unreported area is empty.

LC – Least Concern

Widespread and abundant; not at risk.

Elevation

From 200 georeferenced records, the Eastern Chipmunk is recorded from 4 m13 ft to 1,027 m3,369 ft, with half of sightings below 211 m692 ft.

Each band shows the share of georeferenced sightings that fall within it. Records cluster where people live and hike, so low, populated elevations are over-represented. Read this as observation density, not true abundance.

Commonly confused with

Animals people sometimes mistake for the eastern chipmunk, and how to tell them apart.

Five dark lines and bright borders

The eastern chipmunk is a striped ground squirrel that carries food home in expandable cheek pouches. Five dark stripes run down the back between pale borders. Adults stay small, about six and a half inches long. Weight sits near three ounces. In the northern Great Lakes states the least chipmunk is the mix-up: much smaller, its dark stripes reaching farther onto face and rump.

Burrows, seed stores, and woodland edges

The burrow is the whole operation, a branching tunnel system with chambers for sleeping and caching nuts and seeds. Foraging runs by day along woodland edges, fencerows, and suburban yards, never far from cover. Disturb one and it scolds from safety, a sharp, repeated chip.

Reading a familiar animal’s records

Records follow eastern woodland and suburban edges, while Texas lies near the southwestern edge of the range. A cluster doesn’t measure population size, and a blank area doesn’t prove absence. Only repeated surveys separate real change from a shift in reporting.

Local shelter matters most

The species is listed as Least Concern, though its trend is officially unknown. A wide-ranging animal faces different pressures from one woodlot to the next. The help that matters is local: cover, food, undisturbed den sites. A global category doesn’t watch a particular stone wall.
