Habitat
Yellow-cheeked chipmunks primarily inhabit coniferous and mixed evergreen forests in the Sierra Nevada mountains of California, preferring areas with rocky outcrops, logs, and dense underbrush for cover. They are found at elevations between 1,000 and 3,000 meters, avoiding open areas and thriving in habitats with abundant food sources like acorns and seeds.
Diet
This species feeds on a variety of seeds, nuts, berries, and fungi, supplemented by insects and occasionally small vertebrates. They exhibit foraging behavior during the day, using their cheek pouches to store and transport food back to their burrows. Feeding activity peaks in the morning and late afternoon when they are most active.
Behavior
Yellow-cheeked chipmunks are solitary and territorial, defending small home ranges with vocal calls and chases. They are diurnal, spending their active hours foraging on the ground or in low vegetation, and they hibernate during the winter months in underground burrows. Notable behaviors include storing food in burrows for winter survival and emitting alarm calls to warn of predators.
Conservation Status
The IUCN status of the yellow-cheeked chipmunk is Least Concern, with a stable population trend, though habitat loss from logging and development poses a potential threat.
