Waterfowl are ecologically, culturally, and economically important and their annual and long-term distributions in North America can substantially impact ecological relationships and have economic impacts. In Mississippi, Arkansas and Louisiana alone, recent annual sales of Federal Duck Stamps equal $2.4 million. An intensive study in Mississippi estimated the annual total economic impact of waterfowl hunting in that state was $86.8 million. North American waterfowl number in the millions, use a diversity of aquatic and terrestrial foraging niches, and can feed at rates capable of depleting local food resources. In recent years, waterfowl appear to be wintering at more northern latitudes. Sustained northern...

The annual distributions of waterfowl during autumn-winter can influence ecological, environmental, cultural, and economic relationships. We used previously developed Weather Severity Indices (WSI) that explained migration by dabbling ducks in eastern North America and weather data from the North American Regional Reanalysis to develop an open-access internet-based tool (i.e, WSI app) to visualize and query WSI data. We used data generated by the WSI app to determine if the weather known to elicit southerly migration by dabbling ducks had changed, October – April 1979 – 2014.We detected that the amount of area in the Mississippi and Atlantic Flyways with weather severe enough to cause southerly migration decreased...
