註釋A nationwide State-Federal cooperative study was inistiated in 1978 to examine the effects of September hunting on nesting mourning doves. This study was designed to (1) determine the proportion of the annual total of dove nesting activity and production that occurs in September and October, and (2) determine if survival rates of mourning dove eggs and nestlings are lower in zones where early September dove hunting is permitted than in zones where it is prohibited.
