Factors associated with duck nest success in the prairie pothole region of Canada
Populations of some dabbling ducks have declined sharply in recent decades and information is needed to understand reasons for this. During 1982-85, we studied duck nesting for 1-4 years in 17 1.6 byExpand

Importance of individual species of predators on nesting success of ducks in the Canadian Prairie Pothole Region
We followed 3094 upland nests of several species of ducks. Clutches in most nests were lost to predation. We related daily nest predation rates to indices of activity of eight egg-eating predators,Expand

Red fox spatial characteristics in relation to waterfowl predation
Radio-equipped red foxes (Vulpes vulpes) on the Cedar Creek area in Minnesota were spatially distributed, with individual families occupying well defined, nonoverlapping, contiguous territories.Expand

Differential effects of coyotes and red foxes on duck nest success
Low recruitment rates prevail among ducks in the Prairie Pothole Region of North America, primarily because of high nest depredation rates. The red fox (Vulpes vulpes) is a major predator of duckExpand

Distribution and abundance of predators that affect duck production: Prairie Pothole Region
Abstract : During 1983-88, the relative abundance of 18 species and species-groups of mammalian and avian predators affecting duck production in the prairie pothole region was determined in 33 widelyExpand

Red fox predation on breeding ducks in midcontinent North America
La predation par les renards et d'autres predateurs reduit severement la population d'Anatidae dans la zone etudiee. Les mesures de protection doivent donc viser en premier a reduire la predation

Red fox prey demands and implications to prairie duck production
Experiments were conducted during spring and summer with 33 red foxes (Vulpes vulpes) to determine prey demands, feeding characteristics, and growth rates using natural foods. Pups began eating preyExpand

Interpreting Evidence of Depredation of Duck Nests in the Prairie Pothole Region
Abstract : We examined patterns of depredation of duck nests by 9 species and 2 congeneric species-groups of predators in the Prairie Pothole Region: coyote (Canis latrans), red fox (Vulpes vulpes),Expand

Seasonal predator removal relative to hatch rate of duck nests in waterfowl production areas
The prairie pothole region (PPR) is the primary breeding ground of several species of North American ducks (Bellrose 1980). Much habitat of breeding ducks in the PPR has been destroyed or degraded byExpand
