All 14 young whooping cranes led by ultralights on a southward migration from Wisconsin have arrived in Florida.
The nonprofit Operation Migration reports that seven of the birds arrived Friday at the Chassahowitzka National Wildlife Refuge in Crystal River, Fla.
The other seven cranes being led on the migration were left at a new wintering site at the St. Marks National Wildife Refuge south of Tallahassee.
This year's 1,285-mile migration from central Wisconsin took 88 days.
It's all part of an effort to establish a second migratory flock of the endangered birds in the eastern U.S. The only other flock winters along the Gulf Coast in Texas.
The eastern flock now has 73 cranes in the wild.
