| Abstract: | Using data from 10 preseason and 10 winter major reference areas from 1950-83, the authors tested hypotheses regarding the effects of hunting on the survival and recovery rates of the American black duck (Anas rubripes ). Although estimates of the proportion of total annual mortality due to hunting are low (35% for ad and 45% for young) compared to Blandin‘s (1982) estimates, mean mortality and kill rates have increased since 1982. When hunting regulations were liberalized, recovery rates increased and survival rates decreased in males whereas only recovery rates increased in females. Changes in hunting regulations appeared to affect survival rates of adult males and young American black ducks. |
