The Promise is Sure

It was one of those cool fall mornings on a wetland—low-lying mist slowly moving across the cattails, the sky a dull white making no shadows on the ground.  From the ground level windows of our blind, I could just make out the edges of the camouflage net covering the pen about 100 yards away.  The ground sloped gently toward the marsh and leveled out to the seeded strip which paralleled the pen.  All was quiet among the four of us—a photographer, a poet, a wildlife film producer and myself.  We were waiting, waiting for a glimpse of a young whooping crane, the most endangered crane on earth. 

It took only a few moments for the whisper to be heard.  “There’s one, over there, on the left.” Binoculars and camera lenses swiveled, and then two birds could be seen.  Though only five months of age, their sheer size was astonishing—five feet tall, the tallest bird in North America.  Steadily they advanced on long black legs, necks curled, bright eyes and long beak turning side to side.  

We were not in the Northwest Territories where the only wild migrating whoopers were discovered nesting in the 1950s.  We were not in Texas where those same birds winter at Aransas National Wildlife Refuge.  Neither were we in Florida, where non-migrating whooping cranes have been reintroduced since 1993.  We were in a place where whooping cranes vanished from over 100 years ago.  We were in Wisconsin, at Necedah National Wildlife Refuge.  

We soon saw where the whoopers were heading.  A biologist draped in white from head to shin had entered the pen from the other side, with a full-sized adult crane puppet head on his arm.  “Mom!” (or rather, Dad!).  As obedient as teenagers everywhere, they moved to greet their “parent” and the ultralight aircraft parked nearby.  

It had taken many years to get to this moment.  Since the 1940s, when the world’s population of whooping cranes dwindled to only 16 individuals, crane experts from Canada and the United States have been struggling to rescue this bird from near extinction.  Indeed, it surprises many that whooping cranes did not, like the Carolina parakeet and passenger pigeon, disappear into dusty museum mounts and natural history books, their voices forever silenced.  From an estimated population high of only 1,400 in the 1890s, whoopers had very nearly succumbed four decades later to massive loss of its wetland habitat and indiscriminate killing.  For all the early settlers knew, there was another tall white bird in the next county but the one within shotgun range made as tempting a target as turkeys, and an equally good meal (male whooping cranes typically weigh about 17 pounds).  But thanks to a unique coalition called the Whooping Crane Eastern Partnership, the clear bugle call of this icon of the Endangered Species Act may one day again ring out over the landscape of Wisconsin, and perhaps the whole eastern half of North America. 

Recovery depends on establishing a second migrating flock to help safeguard the remaining wild migrating flock out west (called the Aransas/Wood Buffalo flock) and the second, eight-year old introduced non-migratory flock in Florida, managed by the Florida Fish and Wildlife Conservation Commission.  The Whooping Crane Eastern Partnership formed in 1999 to carry out the second migratory flock reintroduction.  

The project’s complexity called for an array of experts in the Partnership.  The U.S.  Geological Survey’s Patuxent Wildlife Research Center and Madison Wildlife Health Center propagate and raise the chicks from captive pairs, and monitor potential disease issues.  The International Crane Foundation brings 25 years of expertise in crane restoration around the world and key private sector fund raising ability.  The U.S.  Fish and Wildlife Service and Wisconsin Department of Natural Resources manage the nesting and wintering areas and also have responsibilities under Federal and State endangered species laws.  Funding sources are enhanced through the efforts of private non-profit groups including the Natural Resources Foundation of Wisconsin, National Fish and Wildlife Foundation and “Friends” groups throughout the country.  Canada’s Operation Migration Inc.  handle the ultralight training and lead the actual migration study.  These are the same people who first developed the technique in 1988, and were featured in the film “Fly Away Home.” When the International Whooping Crane Recovery Team approved the ultralight technique for teaching the migration route, and chose two national wildlife refuges for nesting and wintering areas, the Partnership was ready to go. 

The monies needed to carry off this project have been jointly provided by government agencies and the private sector.  Funding is needed for items such as design and construction of multiple pens, blinds and migration training areas, propagation, hatching and chick care, veterinary and health checks, medicine, crane chow, radio telemetry and satellite equipment, leg bands, ground school and flight school for the chicks, logo and website development, environmental education and media materials, fund-raising products and events, public meetings, State meetings, Flyway Council meetings, Congressional briefings, correspondence, cell phones, cameras, even gasoline for the planes and vehicles.  Half of the $1.3 million budget for this year was donated by corporations, groups, and individuals who care about cranes and the wetlands upon which they depend.  


In 2000, the Partnership successfully carried out a trial experiment with the more common sandhill crane, leading eleven birds from Wisconsin to Florida.  Now, in 2001, a small flock of whooping cranes and three ultralight parents are prepared to lift off from Necedah National Wildlife Refuge.  They will be accompanied by a Cessna 182, three RVs, two equipment trailers, one mobile veterinary clinic and a baker’s dozen of biologists, pilots, technicians and communications experts on the longest human-led migration study with whoopers in history.  Flying approximately 25 miles each day through seven states, the migration team and cranes will overnight with private landowners, or on state and national wildlife refuges who have volunteered their isolated lands for the project.  Costumes worn by the pilots and biologists maintain wild behavior in the cranes and prevent accidental bonding to humans, an essential ingredient to the reintroduction’s success.  

Their final destination is 31,000 acres of salt marsh at Chassahowitzka National Wildlife Refuge, north of Tampa, Florida.  In spring 2002, the young whoopers are expected to follow their instincts and migrate unaided back to Wisconsin.  After sexually maturing around 4-5 years of age, it is hoped the cranes will mate and raise young who will then learn the migration route from their, shall we say, more natural parents.  Once established, they will likely dispserse to other inviting habitats and the twenty states and two Canadian provinces in the project will welcome them.  The Partnership made sure to include them from the start.  

Navigating over 1,200 miles will not be their only challenge, however.  As with most migratory birds, whooping cranes face other threats: increasing numbers of power lines and cell phone towers which the birds blunder into during migration, danger from chemical and oil spills, drought and loss of food supply in winter and summer habitats, the threat of disease such as the West Nile virus, and occasional illegal killing.  The whooping cranes’ small gene pool demands careful attention to captive bird propagation, essential to this and any reintroduction.  Efforts are now made to avoid use of gathered eggs from the nests of western birds, though that was necessary in the early years of recovery efforts.  

Though the migration study has its risks and some bird losses may occur, some of the best scientific minds and technical skills have been brought together in the Whooping Crane Eastern Partnership.  The immediate outcome is uncertain, but the promise is strong.  The photographs of that first fall morning will be published, the poem will be penned and the film aired.  But nothing will match some future day when a blind won’t be needed to see the beauty of this bird, restored back to the landscape.  The view may be through a mist or cold, clear air, but it will be real and unforgettable.  Instead of “Mom,” those birds will be saying “We are back.”
