Greater Sage-Grouse (Centrocercus Urophasianus) Hen Survival: Effects of Raptors, Anthropogenic and Landscape Features, and Hen Behavior
Survival of breeding-age hens has been identified as the demographic rate with the greatest potential to influence population growth of Greater Sage-Grouse (Centrocercus urophasianus (Bonaparte, 1827); hereafter “Sage-Grouse”). During 2008–2011, we collected summer survival data from 427 Sage-Grouse...
