Identification Of Potential Reintroduction Sites For Whooping Cranes In The Prairie Provinces Of Canada, Dale G. Hjertaas, Brian W. Johns, Wendy J. Lyon
Identification Of Potential Reintroduction Sites For Whooping Cranes In The Prairie Provinces Of Canada, Dale G. Hjertaas, Brian W. Johns, Wendy J. Lyon
Proceedings of the North American Crane Workshop
Action 2.3.3.2.2.1 of the national recovery plan for the whooping crane (Grus americana) calls for the establishment of an independent flock of whooping cranes in Canada, separate from the Wood Buffalo-Aransas flock, that attains a minimum of 25 breeding pairs by 2020 A. D. Potential reintroduction sites include the Prairie Provinces and possibly parts of western Ontario (Edwards et al. 1994). The first step in completing this action is to identify potential reintroduction sites in the 3 Prairie Provinces. We initially screened areas suggested to us by government and Ducks Unlimited biologists. The most important screening criteria were …

Captive-reared Mississippi sandhill cranes (Grus canadensis pulla) reared at the Patuxent Wildlife Research Center (patuxent) have been released at the Mississippi Sandhill Crane National Wildlife Refuge (MSCNWR) since 1981. Of 131 birds released through December 1990, 103 were reared by foster parents. The remaining 28 were experimentally hand-reared in 1989 and 1990. After refining release procedures, parent-reared birds have integrated into the wild flock, many have survived, and some have bred. Releases of hand-reared cranes elsewhere in the 1970's were largely unsuccessful. at least in part due to the lack of a lengthy acclimation period. A new hand-rearing …
Whooping Cranes In Southwest Louisiana: History And Human Attitudes, Gay M. Gomez
Whooping Cranes In Southwest Louisiana: History And Human Attitudes, Gay M. Gomez
Proceedings of the North American Crane Workshop
When whooping cranes (Grus americana) inhabited southwest Louisiana's coastal marshes, residents viewed them as a food source and a crop pest, and shooting was commonplace. Local attitudes have changed as a result of education, stricter law enforcement, and decreased dependence on wildlife for subsistence, but hunting remains widespread. A 1977 proposal to reintroduce whooping cranes to southwest Louisiana generated strong opposition from the Louisiana Wild Life and Fisheries Commission (now Louisiana Department of Wildlife and Fisheries), based on concerns about critical habitat and its likely impact on waterfowl hunting and other traditional marsh uses. These concerns remain, though …
Development Of An Isolation-Rearing/Gentle Release Procedure For Reintroducing Migratory Cranes, Richard P. Urbanek, Theodore A. Bookhout
Development Of An Isolation-Rearing/Gentle Release Procedure For Reintroducing Migratory Cranes, Richard P. Urbanek, Theodore A. Bookhout
Proceedings of the North American Crane Workshop
During 1988 -90, in an effort to develop a reintroduction technique for the whooping crane (Grus americana), we reared 38 greater sandhill crane chicks (G. canadensis tabida) in isolation from humans and gentle-released them on Seney National Wildlife Refuge (NWR) in the Upper Peninsula of Michigan. Chicks were reared in the field with a puppet/costume technique. After chicks completed acclimation to wild conditions in a release pen, we induced them to migrate by breaking their flock into small groups, translocating some groups, and using guide birds. Solutions to migration initiation problems encountered in 1988-89 were developed …
