Human–Wildlife Interactions
When there is a rich guild of nest predators that use different modalities and techniques to locate hidden nests, we hypothesized that no habitat patch characteristic will consistently predict nest success, because if such a characteristic existed then predators would develop a search image based on it and use that characteristic to increase their hunting efficiency for nests. We tested this prediction in the Prairie Pothole region of North Dakota by characterizing the features of 16 habitat patches that contained >1,800 dabbling duck nests. Nest success was monitored during both the early and late nesting season over 2 years. Nest …

Human–Wildlife Interactions
Nest predation often is cited as a primary cause for low recruitment and subsequent population decline of many ground-nesting bird species. In response, managers and researchers have developed a myriad of techniques to reduce rates of predation on ground nests. Fences to exclude predators from nesting areas have reportedly been a successful, albeit expensive, strategy to reduce predation rates. Although many studies have evaluated the use of exclusionary fences as a management tool, nearly all of these studies have evaluated the impact of fences in terms of nest success rather than by actual fence penetration by predators. Many authors, for …
