Effective And Sustainable Prevention Of Avian Damage To Planted Seeds Through Seed Treatment, Jeb A. Barzen, Kenneth E. Ballinger Jr.
Effective And Sustainable Prevention Of Avian Damage To Planted Seeds Through Seed Treatment, Jeb A. Barzen, Kenneth E. Ballinger Jr.
Proceedings of the North American Crane Workshop
Several species of cranes and other wildlife have recovered from low populations because, in part, they have adapted to resources found in agricultural environments. If future conservation strategies are to succeed in areas dominated by agricultural use, we must develop sustainable models that solve crop damage problems that are caused by expanding wildlife populations. Using crane damage to planted seed as an example, we propose 1 such model of sustainable crop damage prevention. The deterrent, 9,10-anthraquinone (AQ), is a natural product produced by plants, in part to control bird frugivory, and induces gastro-intestinal distress (temporarily sickens an individual) in sandhill …
Whooping Crane And Sandhill Crane Monitoring At Five Wind Energy Facilities, Clayton E. Derby, Melissa M. Welsch, Terri D. Thorn
Whooping Crane And Sandhill Crane Monitoring At Five Wind Energy Facilities, Clayton E. Derby, Melissa M. Welsch, Terri D. Thorn
Proceedings of the North American Crane Workshop
Biologists have expressed concern that individuals of the Aransas-Wood Buffalo Population of the federally endangered whooping crane (Grus americana), numbering about 300, may be injured or killed by wind turbines during migration. To help address this concern and curtail (stop) turbine operations when whooping cranes approached turbines, we monitored the area around 5 wind energy facilities in North and South Dakota during spring and fall migration for whooping cranes and sandhill cranes (G. canadensis). Observers monitored cranes for 3 years at each facility from 2009 to 2013 (1,305 total days of monitoring), recording 14 unique observations …
A Preliminary Study Of The Influence Of Breeding Area Density On Sandhill Crane Habitat Selection In South-Central Wisconsin, Sara A. Prussing, Hillary L. Thompson
A Preliminary Study Of The Influence Of Breeding Area Density On Sandhill Crane Habitat Selection In South-Central Wisconsin, Sara A. Prussing, Hillary L. Thompson
Proceedings of the North American Crane Workshop
We hypothesized that territorial sandhill cranes (Grus canadensis) in densely populated breeding areas occupy smaller home ranges that are richer in optimal habitat than those in less densely populated breeding areas. We analyzed satellite telemetry data collected from 2012 to 2016 for 3 and 2 sandhill cranes from dense and less dense breeding areas, respectively. Tracked sandhill cranes in a dense breeding area tended to have smaller home ranges (0.37-14.25 km2) with higher concentrations of wetlands (27%) and row crops (40%) than tracked sandhill cranes in the less dense breeding area (8.80-48.81 km2, 14% …
Winter Distribution Of Sandhill Cranes From Upper Michigan And Adjacent Ontario—A Thirty-Year Perspective, Richard P. Urbanek
Winter Distribution Of Sandhill Cranes From Upper Michigan And Adjacent Ontario—A Thirty-Year Perspective, Richard P. Urbanek
Proceedings of the North American Crane Workshop
The relationship between areas used for breeding and wintering by the expanding Eastern Population of greater sandhill cranes (Grus canadensis tabida) has been little studied. During 1985-1988, 32/33 (97%) of sandhill cranes VHFradiotagged on Seney National Wildlife Refuge (NWR) in the Upper Peninsula of Michigan were subsequently located on wintering areas in wet prairies, muck farms, and improved pastures in Florida and southern Georgia. Four additional radiotagged cranes from other areas of Upper Michigan and 7 from the North Channel of Lake Huron, Ontario, were also located in similar areas and habitats. Winter area was not dependent on …
Mixing Of Two Greater Sandhill Crane Populations In Northeast Oregon, M. Cathy Nowak, Krista J. Mougey, Daniel P. Collins, Blake A. Grisham
Mixing Of Two Greater Sandhill Crane Populations In Northeast Oregon, M. Cathy Nowak, Krista J. Mougey, Daniel P. Collins, Blake A. Grisham
Proceedings of the North American Crane Workshop
The Oregon Department of Fish and Wildlife (ODFW) Ladd Marsh Wildlife Area in northeast Oregon hosts a small group of nesting greater sandhill cranes (Grus canadensis tabida). There were no data on where these birds wintered, and we had no understanding of how these birds fit into the larger picture of western sandhill crane population delineation. ODFW began color-banding pre-fledging colts in 2007 and added satellite tracking with platform transmitter terminals (PTTs) in 2015. To date, we have captured 15 colts and 13 adults and marked them with color bands. We also fitted 1 colt and 8 adult …
