Mechanisms Of Habitat Selection Of Reintroduced Whooping Cranes On Their Breeding Range, Kelly J. Maguire, Stanley A. Temple
Mechanisms Of Habitat Selection Of Reintroduced Whooping Cranes On Their Breeding Range, Kelly J. Maguire, Stanley A. Temple
Proceedings of the North American Crane Workshop
We examined several mechanisms that influenced the habitat selection of reintroduced whooping cranes (Grus americana) on their breeding range in the midwestern United States. Visual observations on 56 whooping cranes from 2001 to 2006 provided accurate locations, habitat descriptions, and bird associations. Location information on each bird was mapped to create home range and to describe the habitat. We found evidence that habitat selection in these cranes resulted from multiple mechanisms, including habitat imprinting, philopatry, site tenacity, intra-specific interactions, and environmental stochasticity. The initial home ranges of all cranes contained habitat similar to that in which they were …
Habitat Selection Of Eastern Migratory Whooping Cranes On Their Wintering Grounds, Lara E. A. Fondow, Stanley A. Temple
Habitat Selection Of Eastern Migratory Whooping Cranes On Their Wintering Grounds, Lara E. A. Fondow, Stanley A. Temple
Proceedings of the North American Crane Workshop
As a monitoring technician for the Whooping Crane Eastern Partnership, I (LEAF) noted that birds in years following release selected wintering habitats that differed greatly from those into which they were initially released. An analysis of the habitat preferences of these birds was needed in order to determine any possible implications to the reintroduction efforts. During the winters of 2004-2005 and 2005-2006, I recorded the locations, habitat use, social associations, and behaviors of all migratory whooping cranes (Grus americana) at known locations in Florida. I used compositional analysis to determine whether habitat use was random at the following …
Impacts Of Global And Regional Climate On Whooping Crane Demography: Trends And Extreme Events, Karine Gil, William Grant, R. Douglas Slack, Enrique Weir
Impacts Of Global And Regional Climate On Whooping Crane Demography: Trends And Extreme Events, Karine Gil, William Grant, R. Douglas Slack, Enrique Weir
Proceedings of the North American Crane Workshop
We analyzed long-term demographic and environmental data to understand the role of large scale climatic factors (the Pacific Decadal Oscillations [PDO]) and environmental factors in 3 regions of North America on natality and mortality of the remnant migratory whooping crane (Grus americana) population. This is an endangered species that spends winters at Aransas National Wildlife Refuge (ANWR) in Texas, breeds at Wood Buffalo National Park (WBNP) in Canada and “…uses Nebraska as a primary stopover”. Long term data (27 years) of demography and environmental factors (PDO index, temperature and precipitation at WBNP, Nebraska and ANWR, pond water depth …
An Individual Whooping Crane's Family History, Karine Gil, Felipe Chavez-Ramirez, Brian W. Johns, Thomas V. Stehn, Robin Silva
An Individual Whooping Crane's Family History, Karine Gil, Felipe Chavez-Ramirez, Brian W. Johns, Thomas V. Stehn, Robin Silva
Proceedings of the North American Crane Workshop
Between 1977 and 1988, 12 cohorts (134 individuals) of whooping cranes (Grus americana) were banded in Wood Buffalo National Park (WBNP, Canada-breeding ground) and monitored from Canada to Aransas National Wildlife Refuge (ANWR, Texas-wintering ground). During 2004, historical data on banded individuals was analyzed to estimate population parameters and life table of the wild population. This study used information from one of the few banded cranes known to be alive in 2008 since 1978. A genealogy tree (Family Tree Maker software) was developed from individual RwR-nil to represent its descendents and relatives, as well as a map (GIS) …
Summary Of Sandhill Crane Hunting Seasons In Kansas 1993-2007, David E. Sharp, Helen M. Hands, James A. Dubovsky, John E. Cornely
Summary Of Sandhill Crane Hunting Seasons In Kansas 1993-2007, David E. Sharp, Helen M. Hands, James A. Dubovsky, John E. Cornely
Proceedings of the North American Crane Workshop
The mid-continent population of sandhill cranes (Grus canadensis) is the largest population of cranes in North America. Hunting seasons for sandhill cranes were closed in 1916 and gradually resumed in Mexico (1940), the United States (1961), and Canada (1964). As knowledge of the biology of cranes and experience with hunting seasons increased, areas in which hunting was permitted expanded, and by 1992 all but 2 states (Nebraska and Kansas) in the U.S. portion of the Central Flyway conducted sport hunting seasons for this population. In 1993 Kansas resumed hunting and initial seasons were limited to specified geographic areas of …
Leg Problems And Power Line Interactions In The Florida Resident Flock Of Whooping Cranes, Jaimie L. Miller, Marilyn G. Spalding, Martin J. Folk
Leg Problems And Power Line Interactions In The Florida Resident Flock Of Whooping Cranes, Jaimie L. Miller, Marilyn G. Spalding, Martin J. Folk
Proceedings of the North American Crane Workshop
We retrospectively reviewed a database with over 1,800 health entries from 296 captive-reared whooping cranes (Grus americana) released in central Florida and 10 wild-fledged chicks from 1992 to 2007. Fifty percent of the study population (n = 306) had 1 or more leg problems that were placed into 4 broad categories: power line interactions (n = 39), other trauma (n = 94), deformities (n = 43), and miscellaneous conditions (n = 106). More males (n = 26, 67%) had power line interactions than females (n = 13, 33%). The majority of these 39 birds died (57%), while the …
