The bison embodies a paradox: immense strength paired with quiet calm. Weighing up to 2,000 pounds and standing 6 feet tall, these giants roam North America's grasslands and river valleys in mobile herds. Photographed here in Yellowstone National Park, Wyoming, they once numbered in the tens of millions but were nearly eradicated in the 19th century—a loss that reshaped ecosystems and disrupted lifeways.

Today, on National Bison Day, observed each year in early November, we honor this iconic species' persistence and profound significance. It's only fitting that this celebration falls at the start of Native American Heritage Month: for countless Native Nations, these animals have been revered as teachers, providers, and spiritual relatives, with every part used thoughtfully for sustenance, clothing, tools, and fuel. That's why tribal communities lead efforts to help them reclaim prairie, wetland, and forest habitats, forming social herds led by matriarchs, sparring males, and curious calves.
