Where Does the American Bison Live?
Native to the North American continent, the American Bison primarily inhabits the Great Plains and the Rocky Mountain regions of the United States and Canada. While they once spanned from Alaska to Mexico and as far east as the Atlantic coast, their modern range is largely restricted to managed national parks, wildlife refuges, and private ranches. Reintroduction efforts have also established small, wild-roaming populations in parts of northern Mexico.

Behavior
American Bison are highly social ungulates that live in herds structured by sex and age. Outside of the mid-summer mating season, or 'rut,' bulls and cows typically live in separate groups. They are remarkably agile for their size, capable of clearing six-foot fences and swimming across wide rivers. Much of their day is spent grazing, punctuated by periods of rest where they chew their cud, similar to domestic cattle.
Interactions with humans should be approached with extreme caution. While they may appear slow or docile, bison are unpredictable and can charge at speeds of up to 35 miles per hour. One of their most distinctive behaviors is 'wallowing'—rolling in dry depressions in the earth to create a dust bath, which helps them shed their winter coat and provides relief from biting insects.

Camera Tips
Capturing the majesty of bison requires a focus on trail selection and equipment durability. Look for established game trails that show heavy hoof traffic or 'wallows'—the distinctive circular dirt pits where they bathe. These wallows are high-activity hubs that guarantee great footage. Because bison are massive and naturally curious, they may use a camera mounting post as a scratching post; use heavy-duty security boxes and mount the camera to a thick, sturdy tree or a reinforced steel post to prevent your gear from being crushed or knocked out of alignment.
For the best framing, mount your camera higher than you would for deer, ideally between 4 and 5 feet off the ground. Angle the lens slightly downward to capture the full scale of the animal rather than just its midsection. Bison are herd animals, so using a wide-angle lens is beneficial to capture the social dynamics of the group rather than a single individual. If your camera allows for it, set a longer video trigger to record their complex vocalizations and social interactions, which are much more frequent than most people realize.
Lighting can be a challenge due to their dark, light-absorbing fur. In bright sunlight, bison often appear as dark silhouettes, while at night, their fur can disappear into the shadows. Use a camera with high dynamic range and set the trigger to 'high' sensitivity to catch them as they move. During the winter, the contrast of their dark coats against white snow is visually stunning, so keep your cameras active year-round. Just be sure to check the battery life frequently, as cold weather and the bison's frequent movement can drain power quickly.
