A group of highly-endangered whooping cranes lives in Wisconsin at the Necedah national wildlife refuge. Problem: how to get them to migrate south for the winter successfully - especially to go to a place where they'll be safe.
Answer: LEAD them south via ultralight aircraft.
It seems as if last year's attempt to do this worked well - the cranes returned on their own - so this year they are doing it again, and you can track the results yourself at
www.bringbackthecranes.org or at
www.operationmigration.org.
