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 shifts in autumn-winter [...]
