| The fact that monarchs migrate to spectacular winter sanctuaries in Mexico was not known until 1975. A Canadian biologist, Dr. Fred Urquhart, had been searching for their destination for nearly 40 years. It took a network of volunteers and several hundred thousand tagged monarchs before the monarch's winter home in Mexico was finally found. National Geographic announced Dr. Urquhart's discovery in the August, 1976 issue of its magazine.
