Whooping cranes occurred naturally in the eastern United States until the mid-twentieth century, and there are records of whooping cranes in Florida until the 1930s. The whooping crane is endangered mainly as a result of habitat loss. At one time, the range for these birds extended throughout Midwestern North America.
In order to help the whooping cranes endure, ultra light aircraft has been used to bring them south for breeding. Prior to 2009, all ultra-light led cranes wintered at the Chassahowitzka
NWR, located near Crystal River, Florida. After a disastrous storm
killed most of the young whooping cranes in 2007, the decision was made
to split the flock into two groups. Now, so long as enough eggs are
available, some juveniles are led to St. Marks and others to Chass. A
total of 27 chicks over the past few years have spent their first winter
growing into young adults on the St. Marks NWR.
So of the migrating birds don't make their destination and for a bird named Levi, it was the lure of romance that always caused him to fall short of his destination.For six years, Levi, an adult whooping crane, would make the
long migration from Wisconsin to Citrus County’s coastline only to come
up a handful of miles short of his summertime haunts in the marshland of
the Chassahowitzka National Wildlife Refuge.Each year when he flew by a female song from a whooping crane in Homosassa Springs Wildlife Park would cause him to fly off course. “She would call out to him when the wild cranes would fly over and he
would dive right in here,” Art Yerian said the park manager. Finally the decision was made to allow Levi to stay at the park and the result could be so new whooping cranes.
