We present the results of a long-term (1970-85) band recovery study of northern bobwhite quail (Colinus virginianus) at Tall Timbers Research Station, Leon County, Florida. The mean annual survival rate of male quail (18.7 ± 1.2[SE] %) was significantly (P = 0.01) greater than that of females (14.3 ± 1.2%). The difference between survival of young (6-9 months old) and adults (>1 yr old) was 3 ± 2.2% and not significant. Survival rates varied significantly among years. The mean harvest was 23.3 ± 0.53%/year. Young male quail were harvested at a significantly higher rate than adult males (2% difference). There was no significant difference between harvest rates of young and adult females. Juvenile male and female harvest rates were not significantly different. However, adult females were harvested at a significantly higher rate than adult males (5% difference). Harvest varied among years. The mean annual kill (harvest rate + crippling loss) was approximately 30% for both sexes. Male and female natural mortality were approximately 52 and 56%, respectively. There was evidence of additivity of hunting and natural mortality for this population harvested in late winter. Our long-term study provides information on the survival processes for northern bobwhite quail that can be used to enhance management of the species.
