Wildlife photography of four members of the Wapiti wolf pack feeding on a bison kill after a successful Winter hunt in Yellowstone National Park

Four wolves from a hunting band of the Wapiti Pack in Yellowstone National Park’s Hayden Valley take a short break from feeding on a bison kill after a successful hunt. Yellowstone is one of the best places in the world to watch, hear and photograph wolves. These packs and animals are carefully tracked and have rich stories to rival any human epic. The white wolf in the middle is a third-generation white alpha female. Both her grandmother and mother were white alpha females of their packs. An alpha male forced out of his pack to the north eventually found his way to the female you see here, and they started the Wapiti Pack with two successful litters. That male has since been forced out by younger males, but while still alive, he was known to sneak in to visit his pups.
