An Update Of The Florida Whooping Crane Release Project Through June 2000, Stephen A. Nesbitt, Martin J. Folk, Kathleen A. Sullivan, Stephen T. Schwikert, Marilyn G. Spalding
Proceedings of the North American Crane Workshop
Whooping cranes (Grus americana) reared mostly at the USGS Patuxent Wildlife Research Center (patuxent) or the International Crane Foundation (ICF) have been released in Florida in an effort to reestablish a nonmigratory population in the southeastern United States. From 1993 through spring of 2000, we released 208 cranes. Modifications to the release procedure instituted in 1995 have greatly reduced mortality from the initial release period. First year mortality has averaged 50%. A longterm drought that began after spring 1998 may have contnbuted to increased first year mortality in recent years. Most mortality has been from predation, mostly bobcat …
Fate Of The Survivors Of The 1995 And 1996 Arizona Trucking Migrations Of Costume-Reared Greater Sandhill Cranes, Daniel P. Mummert, David H. Ellis, Carol L. Chambers
Fate Of The Survivors Of The 1995 And 1996 Arizona Trucking Migrations Of Costume-Reared Greater Sandhill Cranes, Daniel P. Mummert, David H. Ellis, Carol L. Chambers
Proceedings of the North American Crane Workshop
In 1995 and 1996, we trained 2 groups of costume-reared greater sandhill cranes (Grus canadensis tabida) (10 in 1995, 14 in 1996) to follow a truck. Thereafter we led 10 in 1995 and 12 in 1996 from Garland Prairie, northern Arizona, to the Buenos Aires National Wildlife Refuge, southern Arizona (ca. 620 km). These techniques were being developed to create additional, disjunct populations of the whooping crane (G. americana). The cranes taught the migration route in 1995 did not follow the desired migration route in 1996 but did travel north 140 km along the route in …
Effects Of An Early Spring Burn On Greater Sandhill Crane Nesting Success At Malheur National Wildlife Refuge, Oregon, Carroll D. Littlefield, John E. Cornely, Bradley D. Ehlers
Effects Of An Early Spring Burn On Greater Sandhill Crane Nesting Success At Malheur National Wildlife Refuge, Oregon, Carroll D. Littlefield, John E. Cornely, Bradley D. Ehlers
Proceedings of the North American Crane Workshop
A 2430 ha prescribed burn was conducted on Malheur National Wildlife Refuge, Harney County, Oregon in March 1985. About 35 days later, 11 greater sandhill crane (Grus canadensis tabida) pairs nested within the burned area; 9 of these hatched. The remaining 2 clutches were destroyed by coyotes (Canis latrans). Crane hatching success was significantly higher (P = 0.01) on the burned area (81.8%) than elsewhere (38.5%). Two factors were likely responsible for the higher success rate in the burn; nests were placed in deeper water and the smaI1 mammal prey base was temporarily reduced or eliminated …
Models For The Adaptive Harvest Management Of Rocky Mountain Sandhill Cranes: Problems And Potential, William L. Kendall, Roderick C. Drewien
Models For The Adaptive Harvest Management Of Rocky Mountain Sandhill Cranes: Problems And Potential, William L. Kendall, Roderick C. Drewien
Proceedings of the North American Crane Workshop
The migratory Rocky Mountain Population (RMP) of the greater sandhill crane (Grus canadensis tabida) breeds primarily in river valleys, marshes, and meadows of western Montana and Wyoming, southeastern Idaho, northern Utah, and northwestern Colorado. The RMP winters primarily in the Middle Rio Grande Valley of New Mexico, with smaller concentrations in the southwestern parts of that state, southeastern Arizona, and the northern highlands of Mexico. The San Luis Valley of Colorado is used as a stopover in both the spring and fall migrations. The RMP has been hunted on a permit basis since 1981, and currently these cranes …
Nesting Ecology Of Sandhill Cranes At Grays Lake, Idaho, Jane E. Austin, L. J. Ball, Adonia R. Henry
Nesting Ecology Of Sandhill Cranes At Grays Lake, Idaho, Jane E. Austin, L. J. Ball, Adonia R. Henry
Proceedings of the North American Crane Workshop
We examined the nesting ecology of greater sandhill cranes (Grus canadensis tabida) at Grays Lake, Idaho during 1997-99 to detennine the effects of nest-site characteristics and land use on crane nest success. These are preliminary results from 3 years of a 4-year study. Crane nests were located in portions of the Grays Lake basin from early May through late June each year (n = 131 in 1997; n = 131 in 1998; n = 143 in 1999). Apparent nest success varied among years (54% in 1997, 71% in 1998, and 53% in 1999; overall average of 59%). We …
The Importance Of Early Successional Habitats To Rare, Restricted-Range, And Endangered Birds In The Ecuadorian Andes, Mark R. Welford
The Importance Of Early Successional Habitats To Rare, Restricted-Range, And Endangered Birds In The Ecuadorian Andes, Mark R. Welford

Since the mid-1980s, exhausted pastures in Ecuador have been increasingly abandoned, allowing forest regeneration. At approximately 2,200 m in the Tandayapa valley I surveyed four abandoned pastures to evaluate their use by birds. Each former pasture represented a different age of vegetation maturity. The number of bird species recorded in each successively older abandoned pasture increased but only half the number of species recorded in the undisturbed forest site was recorded in the most mature pasture. However, at least four restricted-range bird species were recorded in a single pasture. As pastures rapidly convert to secondary forest, more bird species and …
The Reproductive Biology And Temporal Distribution Of A Great Egret And Nankeen Night Heron Colony At The Perth Zoo, Robyn Phillimore
The Reproductive Biology And Temporal Distribution Of A Great Egret And Nankeen Night Heron Colony At The Perth Zoo, Robyn Phillimore
Theses: Doctorates and Masters
A colony of Great Egrets (Ardea alba) and Nankeen Night Herons (Nycticorax caledonicus) has existed at the Perth Zoo in Metropolitan Perth for over 25 years. The colony is particularly significant for the conservation and management of Great Egrets in Western Australia as it is the only colony located in the Metropolitan area. Baseline information of their breeding biology was needed to facilitate the development of management guidelines for the zoo colony. Foraging behaviour was used to highlight specific adaptations in hunting strategies and diet. However, it was not possible to observe foraging Nankeen Night Herons as they forage at …
Renesting - Female's Success After Nesting Failure And The Renesting Of The Dickcissel (Spiza Americana) At Prairie Ridge State Natural Area, Kevin L. Wentworth
Renesting - Female's Success After Nesting Failure And The Renesting Of The Dickcissel (Spiza Americana) At Prairie Ridge State Natural Area, Kevin L. Wentworth
Masters Theses
Renesting - Female's success after nesting failure. Many birds are unsuccessful in their first nesting attempt, so renesting is often a very important way for birds to increase their lifetime fitness and for populations to maintain stable numbers. I examined the importance of renesting and the factors that encourage or discourage a female from renesting and also the factors that affect the success of these renests. I also looked for patterns in renesting behavior (e.g., renesting interval, renesting distance, percentage of females that attempt renests, and the success of renests) of birds by comparing different studies. I used a total …
