These Endangered Birds Still Face Many Dangers

Blown off
course by strong winds, eight of the 16 young cranes from the Whooping
Crane Eastern Partnership's (WCEP) 2003 ultralight-led migration flew
east of their predicted migration route in April. The group split into
two, with five birds in western Michigan, and three others moving around
in the southern Michigan and northern Indiana area.
The eight
birds veered off course during their first unassisted spring migration
from Florida to central Wisconsin. The group has been moving around western
Michigan and northern Ohio for several weeks, seemingly stymied by how
to cross Lake Michigan.
Biologists
from the International
Crane Foundation and U.S.
Fish and Wildlife Service continue to monitor these eight cranes,
along with their flock mates who have returned to Wisconsin for the summer.
"We
are watching these eight birds very carefully and learning a great deal
from the choices they are making; but mostly, we are just letting them
do their thing," said Kelley R. Tucker, vice president of programs
at the International Crane Foundation, a founding partner of WCEP. "We
also ask that anyone fortunate enough to encounter these birds please
observe them from a distance and not attempt to approach them."
Preventing
the cranes from becoming accustomed to humans is critical to ensuring
their success in the wild. Several incidents along these eight birds'
meandering migration illustrate the rigors faced by wild animals attempting
to navigate and survive in a human world.
For example,
when WCEP biologist Richard Urbanek checked on the group of three when
they moved into the southwest portion of Michigan, he noticed the top
of an aluminum can lodged on the beak of crane number 12-03.
Urbanek was
able to remove the can top by donning a costume, which is worn by caretakers
and pilots when imprinting the young chicks, and then baiting the young
bird with corn. If gone unnoticed, this young female whooping crane could
have perished as she was not able to eat or drink with the piece of trash
preventing her from opening her beak. Ironically the phrase "Please
don't litter-dispose of properly" is visible in a photo of the can
Urbanek removed. (View the photo online at http://www.operationmigration.org/PJ_2004spring-litter.htm)
"We
are overwhelmed by the tremendous support we have received for this project,
and while we appreciate the interest that people worldwide have taken
in these young whooping cranes, we also ask that you help us continue
the success of the reintroduction effort by helping to ensure the 'wildness'
of these young birds," said Tucker.
This is not
the first time whooping cranes have shown up in Michigan in recent years.
In the summer of 2000, two whooping cranes from an experimental non-migratory
flock in Florida migrated more than 1,000 miles on their own to rural
Michigan. This unexpected development resulted in the first whooping crane
sighting in Michigan in more than 100 years. The male of this pair died
during the pair's return autumn journey, but the female made it back to
Florida, and whooping cranes did not return to Michigan again--until recently.
"Michigan
is excited to have these rare birds in our state," said Michigan
DNR Director Becky Humphries. "The people of Michigan will help ensure
these birds are monitored and protected while they are here."
WCEP would
like to thank not only the Michigan
DNR, but also natural resources agencies in Indiana and Ohio,
along with the U.S. Forest
Service in Michigan and others who have helped to monitor these eight
cranes.
The Whooping
Crane Eastern Partnership, an international coalition of public and private
groups, is organizing the effort to reintroduce this highly imperilled
species in eastern North America, which was a part of its historic range.
In 2001,
project partner Operation
Migration's pilots, along with other WCEP members, led the first whooping
crane chicks, conditioned to follow their ultralight surrogates south
from Necedah
NWR to Chassahowitzka
NWR on Florida's Gulf Coast. In 2002 and 2003, Operation Migration
pilots conditioned and guided a second and third group of juvenile cranes
to Chassahowitzka NWR. Those cranes have begun returning to their summer
home in central Wisconsin, and there are now 36 whooping cranes in the
wild in eastern North America.
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
600 feet; try to remain in your vehicle; do not approach in a vehicle
within 600 feet or, if on a public road, within 300 feet. 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.
The whooping
crane chicks that take part in the reintroduction project are hatched
at the U.S. Geological
Survey's Patuxent Wildlife Research Center in Laurel, Maryland. There,
the young cranes are introduced to ultralight aircraft and raised in isolation
from humans. To ensure the impressionable cranes remain wild, project
biologists and pilots adhere to a strict no-talking rule, broadcast recorded
crane calls and wear costumes designed to mask the human form whenever
they are around the cranes.
New classes
of cranes are transported to Necedah NWR each June to begin a summer of
conditioning behind the ultralights to prepare them for their fall migration.
Pilots lead the birds on gradually longer training flights at the refuge
throughout the summer until the young cranes are deemed ready to follow
the aircraft along the migration route.
Graduated
classes of whoopers spend much of their time during the summer on or near
the Necedah and Horicon national wildlife refuges, both of which are in
central Wisconsin. They also use state and private lands. It is not unusual
for yearling cranes to wander, especially if they are not associating
with any male flockmates, which typically select the future breeding territory.
Project staff
from the International Crane Foundation and the U.S. Fish and Wildlife
Service track and monitor southbound cranes in an effort to learn as much
as possible about their unassisted journeys and the habitat choices they
make along the way. ICF and FWS biologists actively track the cranes as
they make their way north, and continue to monitor the birds, along with
Wisconsin Department of Natural Resources biologists, while the whooping
cranes are in their summer locations.
Whooping
cranes were on the verge of extinction in the 1940s. Today, there are
only about 275 birds in the wild. Aside from the 36 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. A non-migrating flock of approximately 100 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.
Many other
flyway states, provinces, private individuals and conservation groups
have joined forces with and support WCEP by donating resources, funding
and personnel. More than 60 percent of the project's estimated $1.8 million
budget comes from private sources in the form of grants, public donations
and corporate sponsors.
