Geographic range
Where Does the Eastern Chipmunk Live?
Native to North America, the Eastern Chipmunk is widely distributed throughout the eastern half of the continent. Its core range extends from southeastern Canada across the northeastern and Midwestern United States, reaching as far south as the Gulf Coast states, though it is absent from the Florida peninsula. This adaptable species thrives wherever there is sufficient ground cover, from the deep Appalachian woods to the leafy suburbs of major metropolitan areas.

Behavior
Eastern Chipmunks are energetic, diurnal rodents known for their industrious nature. They spend the majority of their daylight hours foraging for food to store in their extensive underground burrow systems, which can reach over 3 meters (10 feet) in length. While they are expert climbers, they spend most of their time on the forest floor or atop stone walls and fallen logs, which they use as 'lookout' posts and transit highways.
These animals are primarily solitary and highly territorial, often defending their burrow entrances with sharp 'chipping' vocalizations that sound remarkably like bird calls. Although they are not true hibernators, they enter a state of torpor during the winter, waking up every few days to consume the cache of seeds and nuts they spent the autumn collecting.

Camera Tips
To capture the best footage of an Eastern Chipmunk, camera placement is everything. These rodents are ground-dwellers, so your camera should be mounted no more than 3 to 6 inches off the ground. Aiming the lens along a 'natural highway' like the top of a stone wall, a fallen log, or the edge of a garden bed will yield the most consistent results. Because they are small and fast, ensure your camera has a rapid trigger speed—ideally under 0.3 seconds—to avoid capturing nothing but a disappearing tail.
If you are looking to 'bait' a specific spot for your camera, a handful of black oil sunflower seeds or unsalted peanuts placed on a flat, photogenic rock works wonders. This encourages the chipmunk to pause and stuff its cheek pouches, giving you a perfect window for high-quality photos or video. Focus your camera's focal point on the bait station to ensure the fine detail of their fur and whiskers is captured sharply.
Timing is also key for chipmunk photography. They are most active during the early morning and late afternoon when the light is soft, which also helps prevent the high-contrast 'hot spots' that midday sun can cause on their white stripes. During the autumn 'hoarding' season (September and October), their activity levels skyrocket as they prepare for winter, making this the absolute best time to observe their fascinating cheek-filling behavior.
