The yellow-pine chipmunk (Neotamias amoenus) is a species of order Rodentia in the family Sciuridae. It is found in parts of Canada and the United States. These chipmunks are normally found in brush-covered areas, and in California, they inhabit an elevation range of around 975 to 2,900 metres (3,200 to 9,510 ft).
Their body color is dark and reddish, mixed with cinnamon, with five longitudinal dark (black or mixed black) stripes that are separated by four lighter stripes. The outer pair of pale stripes is creamy white and narrower, and the more median pair is a gray or smoke gray. The sides of the head each have three dark stripes, with two lighter in between, and the crown is black or smoke gray.
Males and females have similar brain size and roughly the same tail length, ear length from notch, and length of lower tooth row, but females are larger in other body measurements; average body mass varies, with large males weighing an average of 49.7 g (1.75 oz) and large females averaging 53.5 g (1.89 oz). Though male-biased size sexual dimorphism is common among mammals, N. amoenus exhibits female-biased dimorphism.

Possible
About 30% of wildlife watchers report a Yellow-pine Chipmunk sighting in Olympic National Park on a given day, based on 270 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 5th most-seen of the 27 mammals we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
June to September
In those months about 40% of wildlife watchers report a Yellow-pine Chipmunk in Olympic National Park on a given day, against under 5% in November to April, the lowest months. Those are among Olympic National Park's driest months, with about 70 mm of rain a month against 370 mm in November.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Yellow-pine 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.
Yes
Of the 5 parks where we can rate Yellow-pine Chipmunk sightings, Olympic National Park has the highest daily chance: about 30%. Next come Glacier National Park (United States, about 20%) and Yellowstone National Park (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the Yellow-pine Chipmunk is recorded against all the mammals logged in Olympic National Park (270 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.
