A bison was seen scratching its chin on a rock at the National Bison Range in Charlo, Montana, video from April 20 shows.
This footage filmed by Cristina Stahl from the US Fish and Wildlife Service (USFWS) shows the large mammal in action. “Bison are masters at finding a good scratching post!” the USFWS wrote in a caption, adding that trees and signs were other prime objects for them to rub against.
