Winter And Migratory Habitat Use Of Six Eastern Greater Sandhill Cranes, Hillary L. Thompson, Anne E. Lacy
Winter And Migratory Habitat Use Of Six Eastern Greater Sandhill Cranes, Hillary L. Thompson, Anne E. Lacy
Proceedings of the North American Crane Workshop
To better understand non-breeding ecology of sandhill cranes (Grus canadensis tabida), we harnessed 6 satellite GPS transmitters to adult cranes from 1 central Wisconsin breeding area. Using location data from these transmitters, we investigated non-breeding movements, including the routes and timing of migration. By combining satellite GPS data with a national land cover dataset, we also described habitat use on stopovers and wintering areas. Sandhill cranes tended to use larger home ranges on long stopovers (>3 days) than on short stopovers (3 days or less). The durations of northward migrations were longer and had more stopovers than …

A Review Of Fall Sandhill Crane Migration Through Indiana, Allisyn-Marie T. Y. Gillet
Proceedings of the North American Crane Workshop
The Indiana Division of Fish and Wildlife conducts surveys from October to December to collect long-term data on greater sandhill cranes (Grus canadensis tabida). Results from these censuses contribute to a fall index of the Eastern Population, which informs wildlife management decisions and research priorities. Recent findings from the annual U. S. Fish and Wildlife Service Fall Sandhill Crane Migration Survey demonstrate a decline in the number of cranes observed at fall staging areas throughout Indiana since 1979. However, nationwide data exhibit a trend of population increase. I provide evidence to show that the apparent decline in the …
Habitat Selection By Breeding Sandhill Cranes In Central Wisconsin, Tamara P. Miller, Jeb A. Barzen
Habitat Selection By Breeding Sandhill Cranes In Central Wisconsin, Tamara P. Miller, Jeb A. Barzen
Proceedings of the North American Crane Workshop
We used compositional analysis to describe habitat use for a dense population of breeding sandhill cranes (Grus canadensis tabida) in central Wisconsin at 2 spatial scales: selection of home range within a study area and selection of habitats within the home range. Habitat use and home range size were estimated from radio-telemetry data from 12 breeding sandhill crane pairs. Research in Wisconsin that was performed on the landscape level suggests that breeding cranes depend on wetlands and do not select upland habitats. Evaluating habitat selection at different spatial levels, such as during different stages of the breeding season, …
