This photo shows a mountain goat that later dropped his head and actively displaced bighorn sheep at a high-elevation snow patch in Glacier National Park in Montana. Joel Berger, a wildlife researcher from Colorado State University, found that mountain goats displace bighorn sheep 95% of the time when there are salt licks involved. In the Tetons, wildlife managers have worked to rid the landscape of non-native goats to prevent competition with sheep.
