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.”
