All 18 young whooping cranes that were led south from Wisconsin with an ultralight last fall were killed in a Florida storm. As of January, 2007, there were 82 surviving Whooping Cranes in the Eastern Migratory Population. Subtract 18 and there may have been additional losses to the whooping cranes in the wild.
Current speculation is that a storm surge drowned the birds. The cranes were being kept in an enclosure at the Chassahowitzka National Wildlife Refuge near Crystal River, Fla.. Official flock status numbers at WhoopingCrane.com will eventually be updated to give the best count.
The other wild whooping crane flock in North America has about 237 birds and migrates from Canada to the Texas Gulf Coast. A non-migratory flock in Florida has about 53 birds. If captive birds are counted, the number of whooping cranes in the world is 500.
