Estimates of survival and recovery rates and the corresponding sample variances and covariances were made for mallards (Anas platyrhychos) banded before the hunting season for the period 1950-85. Estimates were made for adults and young, males and females, for as many banding reference areas as possible using standard band-recovery methods.
