Effects of Weather on Breeding Ducks in North Dakota


Data presented here indicate that weather plays a critical role in the arrival and breeding of waterfowl in the northern plains. Many of our conclusions were supported by reports of other investigators or by reanalysis of their data. Further, we tried to quantify relations between various aspects of weather and important components of waterfowl breeding. Such quantification can be particularly useful in developing models of waterfowl productivity. The observational nature of the data used in this report contrasts with data from experimental studies; the long period over which these data were obtained should complement experimental findings, which are typically of short duration, as well as suggest hypotheses for productive experimental study.
