Band recovery data from 10 preseason and 10 winter populations of the American black duck (Anas rubripes ) were analyzed and survival and recovery rates estimated. Adults showed higher survival rates and lower recovery rates than 1st-year birds. Higher harvest rates of juveniles probably explain much of the age-related mortality differential, but higher vulnerability to nonhunting mortality factors probably also plays a role. Adult males had higher survival rates than adult females but recovery rates were similar to those of adult females. Young males and females had similar survival rates, but recovery rates of young males were higher than those of young females. Further analysis and monitoring of the American black duck population is needed to evaluate the efficacy of current management.
