WCEP NEWS RELEASEWild Whooping Crane Chicks Fledge in WisconsinFOR IMMEDIATE RELEASE
Contact: Joan Garland, 608-381-1262 September 1, 2010 The Whooping Crane Eastern Partnership (WCEP) is celebrating another success in its efforts to reintroduce a wild migratory whooping crane population in eastern North America. Two wild-hatched whooping crane chicks have recently fledged, or become capable of flight. This is only the second time in over a century that naturally produced whooping cranes have fledged in the wild in the Midwest.
The chicks, #W1-10 and #W3-10 (W = wild hatched) were both observed flying with their parents this weekend. Number W1-10 is located on the Necedah National Wildlife Refuge (NWR) in central Wisconsin, and #W3-10 is on private property in Wood County, Wisconsin.
Seven chicks initially hatched this year in the wild, the largest number to hatch in WCEP project history. Wild-hatched chicks face a precarious existence in the first weeks of their lives, and natural loss of chicks due to predation is common. The survival rate for WCEP with these two chicks is within the range of survival rates for wild sandhill crane chicks in south-central Wisconsin currently being studied by the International Crane Foundation.
The two wild whooping crane chicks are the result of renesting. Earlier this spring, nine breeding pairs of whooping cranes built nests and laid eggs, but all nine pairs abandoned those first nests. The nest abandonments earlier this spring are similar to what has been observed in previous years. WCEP is investigating the cause of the abandonments through analysis of data collected throughout the nesting period on crane behavior and black fly abundance and distribution.
In addition to the two wild chicks, 13 whooping crane chicks are being conditioned to follow ultralight aircraft by a field team from Operation Migration and the Patuxent Wildlife Research Center. This fall, Operation Migration will guide the young cranes on their first southward migration from Necedah NWR to Florida, the cranes’ winter home.
An additional 11 chicks will be migrating south as part of WCEP’s Direct Autumn Release (DAR) project. Biologists from the International Crane Foundation and the U.S. Fish and Wildlife Service are currently rearing the whooping crane chicks at Necedah NWR. The chicks will be released this fall in the company of older cranes from whom the young birds learn the migration route. This is the sixth year WCEP has used this DAR method.
In the spring and fall, project staff from the International Crane Foundation and the U.S. Fish and Wildlife Service track and monitor the released cranes in an effort to learn as much as possible about their unassisted journeys and the habitat choices they make both along the way and on their summering and wintering grounds.
Most of the whooping cranes released in previous years spend the summer in central Wisconsin, where they use areas on or near Necedah NWR, as well as other public and private lands.
