Winter Distribution Dynamics and Implications to a Reintroduced Population of Migratory Whooping Cranes

摘要: Abstract From 2001 to 2012, the Whooping Crane Eastern Partnership released 196 costume-reared juvenile whooping cranes Grus americana in eastern United States an effort reintroduce a migratory population of this endangered species. Techniques included leading juveniles from Wisconsin wintering areas by ultralight aircraft or direct release prior their first autumn migration. With few exceptions, ultralight-led on Florida Gulf Coast wintered inland freshwater habitats subsequent winters. Wintering occurred four general regions: Florida–southern Georgia, coastal Carolina, Mid-South (primarily Tennessee and northern Alabama), North (Indiana, Illinois, Kentucky). Releases resulted majority returning winter during early years reintroduction. Later releases shortstopping birds increased numbers ...
