Each year approximately 10 million waterfowl fly north to their breeding grounds in the Prairie Pothole Region of North America, but the landscape that greets them has changed. Weather patterns and agricultural practices have significantly transformed the pothole-dotted native grasslands that waterfowl have used for thousands of years.
These changes have resulted in some waterfowl proliferating while others decline. According to a new study by a Penn State-led research team, nesting date is an important factor in determining winners and losers in the Prairie Pothole Region.
Waterfowl nest in a variety of habitats in the region, including idle grassland, cropland and over water, according to team leader Frances Buderman, assistant professor of quantitative wildlife ecology.

Populations of ducks like these pintails that arrive in the Prairie Pothole Region and nest early in agricultural fields are struggling, according to researchers, who suggest that earlier spring warmups may worsen their situation. (Photo Credit: Delta Waterfowl)
