[Sounds of Whooping Cranes]
The Whooping Crane is one of the most endangered birds in North America. The only flock of Whooping Cranes breeding in the wild migrates between Canada and Texas. To ensure the future of the species, biologists want to establish another wild population that will winter in Florida and breed in Wisconsin.
Unlike many other birds that have an inherent sense of direction and destination, Whooping Cranes have to learn their migration route. But there are not yet enough adults raising young and showing them the way. Enter Operation Migration and ultralight aircraft. [Sounds of an ultralight]
Young cranes, hatched in captivity, hear the sounds of an ultralight’s engine mixed with the brood calls of adult Whooping Cranes. [Sounds of cranes and ultralight]
Pilots, shrouded in white, carry crane puppets and fly the ultralights that will lead the birds on migration. The trainers basically become the birds’ parents. They exercise the young cranes and lead them on short flights. This training is crucial to the cranes’ success, when they take to the air to follow the ultralight on their first migration.

“Seven states and 1285 miles lie between their fledging ground at Necedah National Wildlife Refuge in Wisconsin and their wintering grounds in Florida.”* [Sounds of cranes]
