Anthropogenic Factors Affecting Common Raven Occurrence And Depredation Of Artificial Nests Within Greater Sage‐Grouse Habitat In Southern Utah, Zoë S. Moffett
Anthropogenic Factors Affecting Common Raven Occurrence And Depredation Of Artificial Nests Within Greater Sage‐Grouse Habitat In Southern Utah, Zoë S. Moffett
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Certain species of wildlife are more generalist and adaptive than others. These species often flourish when supported by human activities that provide additional food and habitat for them. The common raven (Corvus corax; hereafter raven) is one such species; their populations have risen and spread throughout the Intermountain West. As generalist scavengers and predators, ravens have been found to pose a severe threat to several threatened or sensitive species, including the greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse). The purpose of my research was to determine the specific anthropogenic and habitat factors that may increase the threat …

The Wellsville Mountains raptor migration study in northern Utah is an ongoing effort to monitor longterm trends in populations of raptors using this northern Rocky Mountain migratory flyway. Raptors feed atop food pyramids, inhabit most ecosystems, occupy large home ranges, and are sensitive to environmental contamination and other human disturbances. Therefore, they serve as important biological indicators of ecosystem health (Cade et al. 1988; Bednarz et al. 1990a; Bildstein and Zalles 1995). For example, long-term migration counts in the eastern United States documented declines in several raptor species and helped us understand the deleterious effects of organochlorine pesticides (Spofford 1969, …
