Behavior

Belding's Ground Squirrels are famously social creatures, living in dense colonies where they communicate through a complex system of vocalizations. You will often hear them before you see them; they emit high-pitched whistles to warn the group of aerial predators and trills to signal ground threats. Their most iconic behavior is the 'picket-pin' stance, where they stand perfectly vertical on their hind legs to scan the horizon for danger, looking much like a wooden stake driven into the ground.

These squirrels are highly seasonal and spend more than half the year in hibernation. In the high-altitude meadows they call home, they emerge as the snow melts to frantically feed and reproduce. Because they are active during the day, they are easy to observe, but they are cautious. While they may become accustomed to humans in campgrounds or mountain residential areas, they generally maintain a safe distance and will scurry to their burrows at the first sign of a threat.

Camera Tips

To capture the best footage of Belding's Ground Squirrels, camera placement is everything. Since these animals rarely climb and spend their lives close to the ground, you should mount your camera just 6 to 12 inches off the deck. Aiming the camera toward a prominent 'sentinel' rock or a mound of freshly turned dirt near a burrow entrance is your best bet for capturing that iconic standing posture. Ensure your camera is tilted slightly upward if it is very low to the ground to avoid cutting off their heads when they stand tall.

Because these squirrels are fast and twitchy, use a camera with a high trigger speed (0.3 seconds or less) and set your device to 'burst mode' or short video clips. A single photo often captures only a blur or a tail, but a three-shot burst is likely to catch the moment they pause to sniff the air. If your camera allows for it, a wide-angle lens is preferred to capture the social interactions of multiple squirrels within the colony rather than just a single individual.

In terms of timing, your window of opportunity is narrow. Depending on the elevation, these squirrels may go into hibernation as early as late July or August and won't reappear until the following spring. Focus your efforts in late June and early July when the juveniles are emerging from the burrows; this is when activity levels are at their peak and the squirrels are most playful and less wary of new objects like a camera housing.

While we don't recommend feeding wildlife, you can naturally attract them to your camera's field of view by placing it near their favorite forage, such as patches of succulent mountain grasses or wildflowers. If you are using a camera in a backyard setting near a mountain cabin, placing the camera near the edge of a mowed lawn and a wilder sagebrush patch provides the perfect 'edge' habitat where they feel comfortable foraging while remaining close to their escape tunnels.

Frequently Asked Questions

Belding's Ground Squirrels are strictly diurnal, meaning they are active during daylight hours. They usually emerge shortly after sunrise once the sun has warmed the ground and are most active during the mid-morning and early afternoon. They may retreat to their burrows during the hottest part of the day in mid-summer.
If you live in their high-elevation range, the best way to attract them is to provide a mix of open, short-grass areas for foraging and nearby cover like sagebrush or rock piles for protection. They are naturally drawn to irrigated lawns in dry mountain climates, but avoid using pesticides which can be harmful to these colonial foragers.
Their diet consists almost entirely of plants. They love the tender shoots of grasses, clover, and various mountain wildflowers. As hibernation approaches in late summer, they pivot to eating seeds and bulbs to maximize their fat reserves for the long winter sleep.
They are generally not found in low-elevation suburban sprawl. However, in high-altitude communities like those around Lake Tahoe or in the eastern Sierra, they are very common in mountain 'backyards,' parks, and golf courses where meadows and human landscapes meet.
Look at the back and sides. Golden-mantled Ground Squirrels have distinct white stripes bordered by black on their sides (similar to a chipmunk but larger). Belding's Ground Squirrels lack these side stripes, having a more uniform grayish-brown body with a subtle reddish wash on the back.
