Townsend's chipmunk (Neotamias townsendii) is a species of rodent in the squirrel family, Sciuridae. It lives in the forests of the Pacific Northwest of North America, from extreme southwestern British Columbia through western Washington and western Oregon. Townsend's chipmunk is named after John Kirk Townsend, an early 19th-century ornithologist.
A large chipmunk, adults can be 36 cm (14 in) from nose to the tip of its tail. In much of its range, it is the only chipmunk; it can be identified by its tail which is grayish above and reddish below, and by its brown coloration with indistinct tawny stripes.
Townsend's chipmunk hibernates in regions where the winter is harsh, but in other parts of its range that have a more mild climate it can be active year-round. It is omnivorous, eating a variety of plants and insects and even birds' eggs. Townsend's chipmunks in the Oregon Coast Range have higher population densities in areas with dense shrubbery, especially salal (Gaultheria shallon). In the summer and early fall, Townsend's chipmunks eat blackberries, salal berries, and thimbleberries. In the late fall, they eat acorns, huckleberries, maple seeds, thistle... Wikipedia →

Possible
About 20% of wildlife watchers report a Townsend's Chipmunk sighting in Olympic National Park on a given day, based on 147 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 27 mammals we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
June and July
In those months about 30% of wildlife watchers report a Townsend's Chipmunk in Olympic National Park on a given day, against under 5% in December to March, the lowest months. Those are among Olympic National Park's driest months, with about 60 mm of rain a month against 370 mm in November.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Townsend's Chipmunk sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Olympic National Park, in our data
Olympic National Park is the only park on Wallace's Line with enough records to rate Townsend's Chipmunk sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Townsend's Chipmunk is recorded against all the mammals logged in Olympic National Park (147 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
