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

Bison mating season is still going on in the park. Male bison are particularly aggressive right now, though all bison and other wildlife can be dangerous. Remember to always keep your distance—25 yards from bison and elk; 100 yards from all other wildlife. #Yellowstone #NationalPark #WhatWildlifeDoWednesday #Bison | Yellowstone National Park
