Duck Nest Success on South Dakota Game Production Areas
نویسنده
چکیده
Duck nesting success was studied on South Dakota Game Production Areas in 1985 and 1986. Mayfield success rates for all species combined were 28.0 and 28.4 percent, respectively. Predators were responsible for nearly 90 percent of nest failures. Results from lake Albert Island and Hogsback served to demonstrate potential for intensive management to increase duck nesting success.

Visual and olfactory concealment of duck nests: in uence on nest site selection and success
Selecting a nest site is an important decision for waterfowl. Because most nest failure is due to depredation, the primary selective pressure in choosing a nest site should be to reduce depredation risk. This task is dif cult, however, because predators use differing tactics to locate nests, such as olfactory or visual cues. The purpose of this research was to evaluate both the olfactory and vi...
متن کاملButeo Nesting Ecology: Evaluating Nesting of Swainson’s Hawks in the Northern Great Plains
Swainson's hawks (Buteo swainsoni) are long-distance migratory raptors that nest primarily in isolated trees located in areas of high grassland density. In recent years, anthropogenic conversion of grassland habitat has raised concerns about the status of the breeding population in the northern Great Plains. In 2013, we initiated a study to investigate the influence of extrinsic factors influen...

Recent advancements in extraction technologies have resulted in rapid increases of gas and oil development across the United States and specifically in western North Dakota. This expansion of energy development has unknown influences on local wildlife populations and the ecological interactions within and among species. Our objectives for this study were to evaluate nest success and nest predat...
متن کاملTemporal Flexibility of Reproduction in Temperate-Breeding Dabbling Ducks
—I compared nesting intervals during three consecutive years in five species of temperate-nesting dabbling ducks (Mallard [Anas platyrhynchos], Northern Pintail [Anas acuta], Northern Shoveler [Anas clypeata], Blue-winged Teal [Anas discors], Gadwall [Anas strepera]) and assessed whether differences existed in timing of refractoriness. Most nesting by females of all five species ended by the su...
متن کاملNest Predation on Black-Tailed Prairie Dog Colonies
Nest predation is the principal cause of mortaliv for many grassland birds. Predation rates may be higher on prairie dog colonies because they may have less available nesting cover and may increase predator abundance. We compared 14-day nest predation rates for 1,764 artificial nests on 102 black-tailed prairie dog (Cynovnys ludovicianus) colonies and their paired off-colony sites (similar habi...
