Abstract

Recent success of Eastern Wild Turkey (Meleagris gallopavo silvestris) reintroductions across southern Ontario has prompted wildlife managers to investigate the potential of extending the northern limit of this subspecies' range. We monitored the survival and reproduction of introduced Wild Turkeys on the Precambrian Shield in central Ontario during 1999–2001. Mean annual survival of 39 radio-tagged hens was 0.288 ± 0.057 SE. Summer and winter survival rates differed between the first and second years of the study. Spring and fall survival rates did not differ significantly between years. Reproductive parameters that characterized the population included a nesting rate of 0.588, mean clutch size of 10.0 eggs/nest, nest success of 0.500, hatching rate of 0.81, hen natality rate of 1.18 females hatched/female, poult survival of 0.54, and fall recruitment of 0.63 juvenile females/breeding hen. Success of the pilot Wild Turkey introduction in central Ontario was compromised by high predation, low numbers of introduced birds, and a prolonged period of deep snow during 2000–2001.
