Ducks Unlimited has put out it's late winter Canadian nesting ground report and over all it look pretty good. There is good snow pack over much of the nesting grounds. This could be another banner year for waterfowl. All the work being done by conservation groups like Ducks Unlimited, Delta Waterfowl and Waterfowl USA pays off when nature provides the water to fill the projects.
