In this ~45 minute interview from October 2019 Rick McIntyre, a 42 year veteran of the National Park Service, discusses his book - The Rise of Wolf 8: Witnessing the Triumph of Yellowstone’s Underdog.
"For decades, Rick McIntyre has been one of Yellowstone’s most dedicated and passionate wolf-watchers. And in his new book, he tells the remarkable story of Wolf 8, one of the first wolves reintroduced to Yellowstone in the mid-'90s, and how the pup went from being runt of the litter to alpha male."
"From June 2000 to August 2015 [Rick] went out into the field for 6,175 consecutive days, and by the end of the day of February 27, 2019, he had 100,000 wolf sightings. He also has compiled more than 12,000 pages of detailed notes."
