Bringing Back the Cranes
The planes and cranes are part of an experiment that began in 2001. Scientists wanted to bring the whoopers back to a part of North America where they vanished over a century ago. The plan will help save this endangered species by starting a whole new flock of migrating, wild Whooping cranes, back in their former range.
