Orange-and-black wings fill the sky as NOVA charts one of nature's most remarkable phenomena: the epic migration of monarch butterflies across North America. NOVA's filmmakers followed monarchs on the wing throughout their extraordinary odyssey. To capture a butterfly's point of view, camera operators used a helicopter, ultralight, and hot-air balloon for aerial views along the butterflies' transcontinental route.
In "The Incredible Journey of the Butterflies," the monarchs take to the air on a two-month, 2,000-mile flight over fields, forests, cities, plains, open water, deserts, and finally mountains to congregate in a tiny, high-altitude region of central Mexico where they've never been before. Incredibly, they arrive by the millions at the same time each year. Unfortunately, illegal logging in the Mexican butterfly sanctuaries threatens the unique habitat that monarchs depend on for their survival.
