Ten young whooping cranes are more than halfway through their migration from Wisconsin to Florida.  

They flew into Alabama from Tennessee today, completing a 110 mile flight landing in Walker County, Ala.   Only six to seven months old, the cranes have now traveled 756 miles and have another 530 miles to go.

"Although the birds' travel and stopovers will be brief in Alabama, our staff is on stand-by to assist this important project in whatever way needed, " said Corky Pugh, Director of Alabama Wildlife and Freshwater Fisheries. "This is just another example of how cooperative efforts can and do lead to the recovery of endangered and threatened species."

The migrating group is minus one whooping crane now, after crane #2-10 was diagnosed with a wing tendon injury yesterday by Nashville veterinarian Dr. Michael Lutz.  The crane had been experiencing problems keeping up with the other ten cranes and had been transported by truck for most of the migration.  This crane will become part of the Whooping Crane Recovery Captive Population and will be sent to a breeding program or to a research or display facility.  He is currently being transported via truck accompanying the migration.

This is the 10th group of birds to take part in a landmark project led by the Whooping Crane Eastern Partnership, an international coalition of public and private groups that is reintroducing this highly imperiled species in eastern North America.  There are now about 106 whooping cranes in the wild in eastern North America thanks to their efforts.

“We are proud to be part of this effort to bring this magnificent bird species back from the brink of extinction,” said Cindy Dohner, Southeast Regional Director for the U.S. Fish and Wildlife Service.  “This is another example of people working together to help overcome monumental challenges that many species face in surviving in a landscape greatly altered by mankind.”
Three ultralight aircraft and the juvenile cranes are traveling through Wisconsin, Illinois, Kentucky, Tennessee, Alabama, and Georgia to reach the birds’ wintering habitats at Chassahowitzka and St. Marks National Wildlife Refuges along Florida's Gulf Coast. 

“Safeguarding an endangered species does not come with guarantees,” said Joe Duff, senior ultralight pilot and CEO of Operation Migration. “This is more than simply an experiment in wildlife reintroduction; it is a struggle against all odds.”

The partnership asks anyone who encounters a whooping crane in the wild:

  • Please give them the respect and distance they need.
  • Do not trespass on private property to view or photograph whooping cranes.
  • Please remain concealed and do not speak loudly enough that the birds can hear you.
  • Do not approach birds on foot within 200 yards;
  • Do not approach in a vehicle within 100 yards and remain in your vehicle.

Why not let the cranes teach each other? We do that too.

In addition to the 11 (now 10) birds being led south by ultralights, biologists from the International Crane Foundation and the U.S. Fish and Wildlife Service reared 11 other whooping cranes at Necedah National Wildlife Refuge released in the company of older cranes from whom the young birds will learn the migration route. They were released on Oct. 25. One was killed on Oct. 30 by a predator at Necedah National Wildlife Refuge. This is the sixth year the partnership has used this Direct Autumn Release method.

The ultralight-led and Direct Autumn Release chicks are this year joining two wild-hatched chicks in the 2010 cohort.

Seven chicks initially hatched this year in the wild, the largest number to hatch in project history.

Wild-hatched chicks face a precarious existence in the first weeks of their lives, and natural loss of chicks due to predation is common. The two wild whooping crane chicks are the result of renesting. Earlier this spring, nine breeding pairs of whooping cranes built nests and laid eggs, but all nine pairs abandoned those first nests. The nest abandonments earlier this spring are similar to what has been observed in previous years. The partnership is investigating the cause of the abandonments through analysis of data collected throughout the nesting period on crane behavior and black fly abundance and distribution.

Background

In 2001, Operation Migration’s pilots led the first whooping crane chicks, conditioned to follow their ultralight aircraft surrogates, south from Necedah NWR to Chassahowitzka NWR in Florida. Each subsequent year, biologists and pilots have conditioned and guided additional groups of juvenile cranes to Florida. Having been shown the way once, the young birds initiate their return migration in the spring, and in subsequent years, continue to migrate on their own. In 2008, St. Marks NWR along Florida’s Gulf Coast was added as an additional wintering site for the juvenile cranes.

Whooping cranes that take part in the ultralight and Direct Autumn Release reintroductions are hatched at the U.S. Geological Survey’s Patuxent Wildlife Research Center in Laurel, Md., and at the International Crane Foundation in Baraboo, Wis. Chicks are raised under a strict isolation protocol and to ensure the birds remain wild, handlers adhere to a no-talking rule and wear costumes designed to mask the human form.

In the spring and fall, project staff from the International Crane Foundation and the U.S. Fish and Wildlife Service track and monitor the released cranes in an effort to learn as much as possible about their unassisted journeys and the habitat choices they make both along the way and on their summering and wintering grounds.

Most of the whooping cranes released in previous years spend the summer in central Wisconsin, where they use areas on or near Necedah NWR, as well as other public and private lands.

Whooping cranes were on the verge of extinction in the 1940s. Today, there are only about 570 birds in existence, about 400 of them in the wild. Aside from the 96 cranes released by the partnership, the only other migrating population of whooping cranes nests at Wood Buffalo National Park in northern Alberta, Canada and winters at Aransas National Wildlife Refuge on the Texas Gulf Coast. A non-migrating flock of about 25 birds lives year-round in the central Florida Kissimmee region.

Whooping cranes, named for their loud and penetrating unison calls, live and breed in wetland areas, where they feed on crabs, clams, frogs and aquatic plants. They are distinctive animals, standing five feet tall, with white bodies, black wing tips and red crowns on their heads.
