Analyzed data of adult mallards banded throughout North America during the past 30 yr, using a model developed to estimate heterogeneity in survival rates of marked individuals. The authors were unable to detect significant differences in heterogeneity between sexes or between birds banded prior to the hunting season (July-September) and after the hunting season (January-February) in the same areas. Heterogeneity varied widely among banding areas. Coefficients of variation of survival rates for adult mallards, adjusted for variation in recovery rates, varied from 18-25%. -from Authors
