James Harris, editor(s)
1991, Book chapter, Proceedings of the 1987 International Crane Workshop
Crane record keeping systems have been evolving at the Patuxent Wildlife Research Center (PWRC) since 1966 and at the International Crane Foundation (ICF) since 1974. The system we present here, a hybrid of the two systems, has been reorganized to promote easy access of information and to limit redundancy....
Cryopreservation of crane semen
G.F. Gee
James Harris, editor(s)
1991, Book chapter, Proceedings of the 1987 International Crane Workshop
The method for the cryopreservation of crane semen at Patuxent Wildlife Research Center is described in detail. Cryopreservation is useful for the long-term storage of crane semen and for specialized propagation needs. A 50% fertility rate from most sandhill cranes, Grus canadensis, inseminated with frozen-thawed semen can...

Past and potential contributions of captive breeding to population recovery of the Whooping Crane
D. H. Ellis, G.F. Gee, D.G. Smith
1991, Book chapter, Acta XX Congressus Internationalis Ornithologici, Volume 4
A captive Whooping Crane colony was established at the Patuxent Wildlifa Research Center in Maryland in 1966. This colony first produced eggs in 1975 and has produced 252 eggs through 1990. From 1976 to 1984, 73 eggs were sent Io Grays Lake, Idaho, the site of the first Whooplng Crane...
Flight restraint techniques for captive cranes

James Harris, editor(s)
1991, Book chapter, Proceedings of the1987 International Crane Workshop
Traditional techniques for preventing escape of captive cranes (i.e., tenotomy, tenectomy, wing clipping, confinement under nets, and amputation) are discussed briefly. Two additional techniques (i.e., brailing and vane trimming) are described in detail. The advantages and limitations of each technique are presented....
Herons and egrets as proposed indicators of estuarine contamination in the United States

James Harris, editor(s)
1991, Book chapter, Proceedings of the 1987 International Crane Workshop
This paper provides the organizational framework, nomenclature, and abbreviated descriptions for all conspicuous nonsocial behavioral units for all 15 species of crane.

We present this compendium...
