In an effort to ensure
the continued survival of Whooping cranes (Grus americana) the
Whooping Crane Eastern Partnership (WCEP) is conducting a multi-year reintroduction
project in eastern North America. To establish this population in a migratory
situation and to encourage wild behaviour, each new generation of captive-hatched
cranes is costumed-reared, isolated from human environments and conditioned
to follow custom modified ultralight aircraft. Using this method the cranes
are guided by the aircraft in autumn along a 1200-mile, pre-determined
migration route from the Necedah National Wildlife Refuge in Wisconsin
to the Chassahowitzka National Wildlife Refuge in Florida.
Thirty-three sub-adult
Whooping cranes that were led along this route during the first three
project years continue to select suitable habitat, avoid humans, and migrate
unaided twice each year. An additional 14 sub-adults successfully made
their first migration in the fall of 2004, which brings the total of whooping
cranes reintroduced to eastern North America to forty-seven (47). A number
of prior year birds will be approaching breeding age and we hope to observe
the first attempts at pairing, and quite possibly nesting behavior this
coming year. The goal of the project is to establish a discrete, self-sustaining
population of at least 125 birds containing a minimum of twenty-five (25)
breeding pairs as proposed by the Canada/United States Whooping Crane
Recovery Team. This pioneering flock will augment the only naturally occurring
population that migrates in the west, between northern Canada and southern
United States, and the non-migratory flock reintroduced into central Florida
beginning in 1993.
There were a number
of challenges again this year including: 1) weather conditions that slowed
the ultralight migration to a record 64 days, 2) loss of two prior year
sub-adults, 3) late migration of prior year birds due to a very warm early
fall and winter and 4) subsequent dispersal of a small number of those
birds along the migratory route. However, these challenges were addressed
by the partnership and the project has seen another successfully year
overall. Future challenges include: 1) continued consideration of moving
the ultralight migration route to the West to avoid the Appalachian mountains,
2) changes in winter pen management to deal with overlap of ultralight
birds and prior year sub adults, 3) future genetic management of the population
and 4) possible initiation of a supplemental release technique teaching
birds to migrate by releasing them with experienced adults, and 5) continuing
difficulty to meet project funding goals each year.
The project continues
to receive enthusiastic governmental, public and private support and has
stimulated interest in protecting and restoring habitats for whooping
cranes, other birds and associated wetland species along the route and
has also been a strong focus of environmental education efforts. The Power
of Partnership continues to effectively support our collective efforts
to restore this endangered species and symbol of international conservation
to Eastern North America.
