Bison Adaptations in Winter

Casey Anderson, a wildlife filmmaker, explores Yellowstone National Park in winter, highlighting the American bison's remarkable adaptations to survive harsh conditions. Bison have thick woolly coats and large bodies that generate heat, allowing them to thrive in extreme cold. They conserve energy by moving in single file and utilize Yellowstone's geothermal areas for warmth and food access. Casey contrasts his reliance on animal-inspired clothing with the bison's natural adaptations.
