Breeding Biology Of Greater Sandhill Cranes On The Roseau River Wildlife Management Area, Minnesota, Jodie L. Provost, Thomas A. Provost, Stephen J. Maxson, Richard D. Crawford
Proceedings of the North American Crane Workshop
The breeding biology of greater sandhill cranes (Grus canadensis tabida) on the Roseau River Wildlife Management Area in northwestern Minnesota wa.'I studied from April 1989 to October 1990. A minimum of 0.25 breeding pair per km2 of wetland and upland nested on the study area. Except for distances to nearest shrub from nest and random sites (P = 0.047), there were DO significant differences among mean habitat values or distributions of variables measured at nest and random sites (P > 0.05). Mean clutch size was 1.88 ± 0.33 (SD) eggs for 17 clutches in 1989 and 1990. In 1990, …

Sandhill Crane Habitat Use In Northeastern Utah And Southwestern Wyoming, Donald E. Mcivor, Michael R. Conover
Proceedings of the North American Crane Workshop
Patterns of habitat use by greater sandhill cranes (Grus canadensis tabida) were examined during April-July 1991 when crop damage attributed to cranes normally occurs. We conducted surveys weekJy along 37-km transects in Cache Valley, Utah, and bi-weekly in the Bear River Valley in Rich County, Utah, and Lincoln County. Wyoming. During the surveys, we sighted 1,235 cranes in 165 separate groups in pasture (55%), small grains (19%), riparian (8%), alfalfa (6%), corn (3%), and miscellaneous (9%) habitats. Cranes did not use habitats in proportion to their availability (P < 0.0005); they fed more in small grain fields and pasture-hay habitats. Depredations attributed to cranes have been reported in Cache Valley corn crops in spring and in Bear River Valley small grain crops in fall. Farmers with chronic depredation problems in small grains and corn may wish to cultivate crops less preferred by cranes.
