National Bison Day

If ever there was an animal that deserved some recognition, it's the bison. Since 2012, National Bison Day has been observed on the first Saturday of November to acknowledge the animal's cultural, historical, and economic significance—as well as its remarkable comeback. Bison were once plentiful in North America. Tens of millions strong in the 1800s, they roamed in great herds, helping to diversify and maintain the prairie habitat. They've also played several important roles in Native American cultures. Indigenous peoples have used every part of the bison for food, utensils, and clothing—and they pay tribute to the giant beasts in religious rituals.

Settlement of the American West caused habitat loss for the bison and that, combined with overhunting, nearly wiped out the species altogether—until ranchers, conservationists, and politicians teamed up to save them. In 1913, 14 bison from the Bronx Zoo were shipped to a wildlife refuge to revive the population. Fast forward to today, and more than 20,000 bison roam on public lands in the United States.
