Look who had a "hayday"! 🦬 Takoda, Teetoka, Willow and Juniper made the most of the fall-themed enrichment provided by their zookeepers – there were even two full-sized repurposed pine trees! National Bison Day is not just a time to treat the bison at the Zoo but also to learn about their wild counterparts. Bison graze all day, an activity that helps promote grassland diversity and is crucial for prairie health. This keystone species once roamed almost all of the continental United States, but was near extinction in the late 19th century. Conservation efforts have helped this species rebound in a big way, which is great for the species and American prairies. See the bison at the Detroit Zoo to learn more today! #DetroitZoo #Bison #NationalBisonDay #Enrichment #Heyday #AnimalFun
