The Flight of the Whooping Crane
Whooping cranes are among the rarest birds in the world; barely 150 survive. Twice each year they make a perilous journey of 2,500 miles, from the Gulf of Mexico to their nesting-grounds in Canada and back again.
One spring a family of whoopers were pursued the length of the continent. By car and plane, three men were trying to follow the cranes on migration for the first time. If they succeeded, the knowledge gained would help to save the cranes.
Elsewhere in North America, equally elaborate and often bizarre measures are being taken to help the whooping crane on its long flight back from the brink of extinction. Narrator Barry Paine Produced for the National Geographic Society/WQED
