Eastern wild turkey (Meleagris gallopavo silvestris) populations have increased considerably in Illinois since near extirpation in the early 20th century and have increased in popularity among hunters and residents. Although wild turkeys have been studied extensively, most wild turkey research has been conducted in areas of vast forest land cover containing very little agriculture or grassland. I am studying wild turkey ecology in a diverse southern Illinois landscape consisting of a mixture of agriculture, grassland and forest elements. During 2008-10, I will capture and radiomark turkey hens and use radiotelemetry to determine nest-site locations, brood-rearing areas, and home ranges. Habitat measurements and hen/nest predation will be assessed in areas used by turkeys. Survival of nests, broods, and hens, and influence of habitat covariates, will be assessed using program MARK. Habitat selection within core areas versus home ranges will be quantified using compositional analysis. My study will provide wildlife biologists with information necessary for managing wild turkeys and their habitat in spatially heterogeneous Midwestern landscapes.
