The alpha wolves of yellowstone ()

Over the course of his four decades observing wolves in the wild, including 28 in Yellowstone National Park, retired ranger Rick McIntyre has recorded over 100,000 wolf sightings, more than any other person on the planet. A renowned wolf behaviorist, he was one of the first park rangers to work on the Yellowstone Wolf Reintroduction Project and educate the public about the park’s wolves.
