Evaluation of Nicarbazin as a Potential Waterfowl Contraceptive Using Mallards as a Model
ABSTRACT Contraception may provide a useful nonle-thal management tool to reduce wild bird populations. We tested the efficacy of nicarbazin (NCZ) as a contracep-tive for waterfowl and assessed health effects of NCZ, using domestic mallards (Anas platyrhynchos) as a model for Canada geese (Branta ca...
