Tuesday, January 27 at 8 p.m. – NOVA: The Incredible Journey of the Butterflies
(Rochester, NY)– 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.
Stockard Channing narrates the film of breathtaking beauty and beguiling mystery. NOVA: The Incredible Journey of the Butterflies airs Tuesday, January 27 at 8 p.m. on WXXI-TV 21 (cable 11) and WXXI-HD (cable 1011 and DT 21.1).
Capturing a butterfly’s point of view with exquisite footage, NOVA follows monarchs on
the wing throughout their extraordinary odyssey. Camera operators used a helicopter,
ultralight, and hot-air balloon for stunning aerial views along the butterflies’ transcontinental route, together with ground-level shots captured by running with the traveling swarm
The film opens with caterpillars munching milkweed in southern Canada in late summer.
Soon each caterpillar transforms itself into a silky chrysalis; and about ten days later, a
delicate four-winged monarch emerges.
Then, at some unknown signal, 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.
Shedding light on this natural wonder are some of the world’s leading monarch researchers, including Lincoln Brower of Sweet Briar College, independent biologist Bill Calvert,
and Orley “Chip” Taylor of the University of Kansas.
Putting the monarch phenomenon into perspective, Taylor says, “You’ve got a butterfly
that’s originating in Toronto, or it’s originating in Detroit, Michigan, or it’s coming down
from St. Paul or maybe even Winnipeg, and it’s moving south. Somehow it finds its way to
Mexico. Could you do that?”
No one yet knows how the butterflies do it, but Taylor’s research reveals that they are expert navigators. In one experiment, he transported Mexico-bound monarchs from
Kansas to Washington, DC, and then set them loose. At first, they flew south as if they
were still in Kansas—a course that from Washington would miss Mexico entirely.
But after a few days, they corrected their flight path, as if some inborn GPS unit had alerted them to the
true direction of their destination.
In another sequence, NOVA accompanies celebrated monarch watcher Bill Calvert around backcountry
Texas as he looks for signs of the monarch migration. Sure enough, they show up en masse and on time,
heading toward the Sierra Madre mountains across the border—the last leg of their flight.
And in the Mexican state of Michoacán, NOVA joins mountain villagers as they celebrate the arrival of
the monarchs in the first week of November. The butterflies’ arrival marks the start of a celebration called
the Day of the Dead, since the local people have traditionally associated the monarchs with the returning
souls of their departed ancestors.
Unfortunately, illegal logging in the Mexican butterfly sanctuaries threatens the unique habitat that
monarchs depend on for their survival. Monarchs may not yet be an endangered species, but their annual
migration is an endangered phenomenon that could dwindle to insignificance if the giant firs that they
cling to during the winter disappear.
Gone also would be the colorful festival that closes The Incredible Journey of the Butterflies—a
fireworks display welcoming the hardy fliers to Mexico, with orange bursts against the black sky, looking
almost like the beautiful cloaks of the monarchs.
