First Whooping Cranes of the Class of 2008 Arrive At Necedah National Wildlife Refuge

Seven whooping crane chicks arrived June 25 at Necedah National Wildlife Refuge in central Wisconsin to begin preparation for their fall migration behind ultralight aircraft. The seven chicks are members of the “Class of 2008”, which will be the eighth flock of endangered juvenile whooping cranes to take part in a reintroduction project conducted by the Whooping Crane Eastern Partnership (WCEP), a coalition of public and private organizations.  Thanks to the efforts of WCEP’s members, there are now 72 wild, migrating cranes in eastern North America, which was part of their historic range.

A field team from Operation Migration, Inc. and the Patuxent Wildlife Research Center will spend the summer strengthening the social cohesion of the flock and teaching them to fly behind the ultralights.  This fall, Operation Migration will use ultralights to guide the young cranes on their first southward migration to Florida, the cranes’ winter home.

In addition to the ultralight-led birds, biologists from the International Crane Foundation and the U.S. Fish and Wildlife Service are rearing whooping crane chicks that will be released this fall into the company of older birds, from whom the young birds will learn the migration route from Necedah NWR to Florida.  This is the fourth year WCEP has used this Direct Autumn Release method, which supplements the success of the ultralight migrations.

In 2001, the first whooping crane chicks were led south behind ultralight aircraft from Necedah NWR to Chassahowitzka NWR, passing through Tennessee and resting at the Tennessee Wildlife Resources Agency’s Hiwassee Wildlife Refuge, on their way to Chassahowitzka NWR.  Each subsequent year, WCEP biologists and pilots have conditioned and guided additional groups of juvenile cranes to Chassahowitzka NWR.  Once led south, the cranes are able to migrate on their own, without assistance, in following years.

Most graduated classes of whooping cranes spend the summer in central Wisconsin, where they use areas on or near the 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 530 birds in existence, 380 of them in the wild.  Aside from the 72 Wisconsin-Florida birds, the only other migrating population of whooping cranes nests at the Wood Buffalo National Park in the Northwest Territories of Canada and winters at the Aransas National Wildlife Refuge on the Texas Gulf Coast.

This year the Wood Buffalo-Aransas flock reached a record size, as biologists counted 266 individuals on the Aransas wintering grounds.

A non-migrating flock of approximately 40 birds lives year-round in the central Florida Kissimmee region.  The remaining 150 whooping cranes are in captivity in zoos and breeding facilities around North America.

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.

WCEP asks anyone who encounters a whooping crane in the wild to please give them the respect and distance they need.  Do not approach birds on foot within 200 yards; try to remain in your vehicle; do not approach in a vehicle within 100 yards.  Also, please remain concealed and do not speak loudly enough that the birds can hear you.  Finally, do not trespass on private property in an attempt to view whooping cranes.
