As we move into the bison mating season (the rut) groups of bison will be at their largest. Give wildlife the right of way when they cross the road, stay inside your vehicle, and use pull-outs when you stop for photos. #YellowstonePledge | Yellowstone National Park

Sound on to hear bison bellows! 🔊 Mating season is in full swing at Neal Smith National Wildlife Refuge in Iowa. Bison bulls compete for a chance to mate, making deep vocalizations that echo across the prairie. 🎥 Nancy Corona/USFWS | U.S. Fish and Wildlife Service
