Abstract

Banding and recovery data from 3 populations of winter-banded canvasbacks (Aythya valisineria) were analyzed and survival and recovery rates were estimated. Sex-specific differences in these rates were detected in some populations, and lower survival rates were exhibited by females. Some geographic variation in survival rates was evident, suggesting that canvasbacks should not be managed strictly on a continent-wide basis. Evidence of temporal variation in both survival and recovery rates was found. Lower recovery rates were noted during periods of restrictive hunting regulations, but the relationship between survival rates and hunting regulations was not clear-cut.
