Common Raven Density And Greater Sage-Grouse Nesting Success In Southern Wyoming: Potential Conservation And Management Implications, Jonathan B. Dinkins

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Declines in the distribution and abundance of greater sage-grouse (Centrocercus urophasianus; hereafter "sage-grouse") in western North America over the past century have been severe. The goal of my research was to increase the understanding of factors influencing where sage-grouse hens placed their nests, how common ravens (Corvus corax: hereafter "raven") impacted sage-grouse nest success, and whether high raptor densities negatively impacted hen survival of sage-grouse. I compared raven and raptor densities at sage-grouse nest and brood locations to available habitat. I also assessed how sage-grouse positioned their nests and broods relative to proximity to man-made structures, …
