Abstract
Contrasted first-year recovery rates of Anas platyrhynchos during the pre-point system period (1960-69) and during a point system period (1972-84). Little change in recovery rates of male and female mallards took place since initiation of the point system. Lacking a controlled experiment, it was not possible to attribute the small changes found to point system regulations, or to discern whether the reduction in female recovery rates was the result of the point system. -from Authors
