Storm kills 18 whooping cranes
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.

Birds most likely drowned by storm surge

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 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.

"Operation Migration" leads whooping cranes from Wisconson to Florida every October. Watch how on this National Geographic video. You can track their progress here.

On Friday, a group of endangered whooping cranes took to the skies, migrating from Necedah, Wisconsin, to their winter habitat in Florida—1,200 miles away.

The 20 cranes, which were hatched and raised in captivity, have to be taught to migrate. (Whooping cranes learned their migration route by following their parents, but the knowledge was lost when the population dwindled and no wild birds used the flyway.) So Operation Migration's pilots in ultralight planes lead the birds south.

The birds' route takes them from the Necedah National Wildlife Refuge, in Wisconsin, to the Chassahowitzka National Wildlife Refuge in Florida. Read the Operation Migration field journal to see where the flock is today and what's been happening to them.
