Distribution patterns of American black duck and mallard winter band recoveries Distribution patterns of American black duck and mallard winter band recoveries
We compared the distribution patterns of winter band recoveries of American black ducks (Anas rubripes) and mallards (A. platyrhynchos) banded in the same breeding areas. Young black ducks wintered northeast of young mallards but no differences in distribution patterns were detected between adult birds of the 2 species. Mallards exhibited greater temporal variation in distribution...

Distribution patterns during winter and fidelity to wintering areas of American black ducks Distribution patterns during winter and fidelity to wintering areas of American black ducks
The distribution patterns during winter of American black ducks (Anas rubripes) were compared among age – sex classes using band recovery data. In addition, fidelity to wintering areas was compared between sexes and between coastal and inland wintering sites. We did not find evidence of age- or sex-specific differences in distribution patterns (P > 0.10). Black ducks exhibited a stronger...
