Management Of Lands Along The Platte River Fromelmcreek To Lexington, Nebraska, As Crane Habitat, James J. Jenniges, Mark M. Peyton
Management Of Lands Along The Platte River Fromelmcreek To Lexington, Nebraska, As Crane Habitat, James J. Jenniges, Mark M. Peyton
Proceedings of the North American Crane Workshop
To meet Federal Energy Regulatory Commission (FERC) license requirements for the operation of 5 hydroelectric power plants on the North Platte and Platte Rivers in Nebraska, the Nebraska Public Power District (NPPD) and The Central Nebraska Public Power and Irrigation District (Central) together have become the second largest owners and managers of lands for the conservation of endangered species and migratory waterbirds along the central reach of the Platte River. We describe here the management activities on the properties, success of the management in achieving objectives, and the response of sandhill (Grus canadensis) and whooping cranes (G. …
New Hunter Education Strategies To Protect Whooping Cranes In Texas And Kansas, Lee Ann Johnson Linam, Helen M. Hands, Jay Roberson
New Hunter Education Strategies To Protect Whooping Cranes In Texas And Kansas, Lee Ann Johnson Linam, Helen M. Hands, Jay Roberson
Proceedings of the North American Crane Workshop
The decline of the whooping crane (Grus americana) has often been attributed primarily to loss of habitat and overharvest. Although hunting of whooping cranes is now prohibited, shootings sometimes occur. Recent incidences have prompted the Texas Parks and Wildlife Department (Texas) and the Kansas Department of Wildlife and Parks (Kansas) to develop new strategies that increase hunter recognition of legal game species and awareness of endangered species concerns. Both agencies have produced or updated publications for goose and sandhill crane (Grus canadensis) hunters. Texas has developed video news releases for the general public and a video/DVD …
Safety Of West Nile Virus Vaccines In Sandhill Crane Chicks, Glenn H. Olsen, Kimberli J. Miller, Douglas E. Docherty, Valerie Bochsler
Safety Of West Nile Virus Vaccines In Sandhill Crane Chicks, Glenn H. Olsen, Kimberli J. Miller, Douglas E. Docherty, Valerie Bochsler
Proceedings of the North American Crane Workshop
West Nile virus arrived in North America in 1999 and has spread across the continent in the ensuing years. The virus has proven deadly to a variety of native avian species including sandhill cranes (Grus canadensis). In order to provide safe and efficacious protection for captive and released populations of whooping cranes (G. americana), we have conducted a series of four research projects. The last of these was a study of the effects of two different West Nile virus vaccines on young Florida sandhill crane (G. c. pratensis) chicks and subsequent challenge with the virus. …
Infectious Bursal Disease In Wild Populations Of Turkeys And Sandhill Cranes: Preliminary Findings, Kristen L. Candelora, Marilyn G. Spalding, Stephen A. Nesbitt, Holly S. Sellers, Jeremy Olson, Larry Perrin, Jeannette Parker
Infectious Bursal Disease In Wild Populations Of Turkeys And Sandhill Cranes: Preliminary Findings, Kristen L. Candelora, Marilyn G. Spalding, Stephen A. Nesbitt, Holly S. Sellers, Jeremy Olson, Larry Perrin, Jeannette Parker
Proceedings of the North American Crane Workshop
Captive-reared whooping cranes (Grus americana) released into Florida for the resident reintroduction project experienced unusually high mortality and morbidity during the 1997-1998 and 2001-2002 release seasons (Spalding et al. 2008). Infectious bursal disease virus (IBDV) serotype 2 is currently under investigation as the factor that precipitated the mortality events. A small percentage of whooping cranes have been exposed to IBDV in the captive setting. However, many more are being exposed postrelease, and prevalence of exposure seems to increase with age or length of time the birds are in the wild in Florida (Spalding et al. 2008). The goals …
Factors Influencing Greater Sandhill Crane Nest Success At Malheur National Wildlife Refuge, Oregon, Gary L. Ivey, Bruce D. Dugger
Factors Influencing Greater Sandhill Crane Nest Success At Malheur National Wildlife Refuge, Oregon, Gary L. Ivey, Bruce D. Dugger
Proceedings of the North American Crane Workshop
We used logistic regression to model the effects of weather, habitat, and management variables on Greater Sandhill Crane (Grus canadensis tabida) nest success at Malheur National Wildlife Refuge in southeast Oregon. We monitored 506 nests over 9 breeding seasons. Mean apparent nest success was 72% ± 4% and varied from 51 to 87%. Nest success was lower one year after a field was burned and declined with nest initiation date. Nest success was higher during warmer springs, in deeper water, and in years with moderate precipitation. Haying, livestock grazing, and predator control did not influence nest success. We …
Hunting Success For Mid-Continent Sandhill Cranes In The Central Flyway: Comparing Current And Historic Results, James A. Dubovsky, Adrianna C. Araya
Hunting Success For Mid-Continent Sandhill Cranes In The Central Flyway: Comparing Current And Historic Results, James A. Dubovsky, Adrianna C. Araya
Proceedings of the North American Crane Workshop
Sport hunting for the Mid-continent population of sandhill cranes (Grus canadensis) in the United States resumed in New Mexico in 1961 after a 45-year moratorium. Interest in crane hunting continued to increase and by 1975, 8 states were participating in sandhill crane hunting. Currently, hunting seasons have been established in all Central Flyway states except Nebraska. Efforts to collect information on the annual harvest of sandhill cranes began in 1975 when hunters were required to obtain federal sandhill crane hunting permits. The permits included a hunting diary whereby hunters were asked to record information about their daily hunting …
Sandhill Crane Wintering Ecology In The Sacramento-San Joaquin Delta, California, Gary L. Ivey, Caroline P. Herziger
Sandhill Crane Wintering Ecology In The Sacramento-San Joaquin Delta, California, Gary L. Ivey, Caroline P. Herziger
Proceedings of the North American Crane Workshop
We studied wintering sandhill crane (Grus canadensis) ecology in 2002–2003 in the Sacramento-San Joaquin Delta of California, focusing on Staten Island, a corporate farm which was acquired by The Nature Conservancy and managed to promote sustainable agriculture that is beneficial to wildlife. Our purpose was to define habitat conservation needs for cranes, including the state-threatened greater subspecies (G. c. tabida). Research was conducted through intensive surveys by vehicle of crane foraging and roosting behavior. We estimated that about 1,500 greaters used Staten Island, which is a significant portion of the Central Valley Population of greater sandhill …
Spring Migratory Habits And Breeding Distribution Of Lesser Sandhill Cranes That Winter In West-Central New Mexico And Arizona, Gary L. Krapu, David A. Brandt
Spring Migratory Habits And Breeding Distribution Of Lesser Sandhill Cranes That Winter In West-Central New Mexico And Arizona, Gary L. Krapu, David A. Brandt
Proceedings of the North American Crane Workshop
Little information exists on the spring migratory habits and breeding distribution of lesser sandhill cranes (Grus canadensis canadensis) that winter in west-central New Mexico and southeastern Arizona. To address this question, we captured and attached a total of 6 Platform Transmitting Terminals (PTT) to adult lesser sandhill cranes at 2 sites each in west-central New Mexico and southeastern Arizona during December 2001 and monitored the birds’ movements to arrival on their arctic breeding grounds. After departing from their wintering grounds, 2 of the cranes stopped at Monte Vista NWR in south-central Colorado where they stayed for 17 and …
Is The Annual March Survey Of The Midcontinental San Dhill Crane Population Appropriately Timed To Reliably Estimate Population Size?, Gary L. Krapu, David A. Brandt
Is The Annual March Survey Of The Midcontinental San Dhill Crane Population Appropriately Timed To Reliably Estimate Population Size?, Gary L. Krapu, David A. Brandt
Proceedings of the North American Crane Workshop
The U.S. Fish and Wildlife Service relies on an annual aerial photo-corrected survey conducted on the fourth Tuesday of March each year in the Central Platte River Valley (CPRV) and North Platte River Valley (NPRV) of Nebraska to estimate size of the midcontinental population (MCP) of sandhill cranes (Grus canadensis) to help guide population management. Wide unaccounted for annual fluctuations in survey counts over the past 25 years have raised concerns that many cranes either have left the Platte before the survey, have not yet arrived, or over fly the Platte entirely in some years. As a result, …
