Forty years ago, North American waterfowl were in serious decline. In May 1986, the North American Waterfowl Management Plan was signed between the United States and Canada, and in 1994 Mexico signed the Plan. Today, most waterfowl populations are thriving — doing better than any other group of birds on the continent. This film tells the story of how three nations chose collaboration over crisis, and what four decades of partnership have built: millions of acres restored, ecosystems sustained, and communities connected to the landscapes they depend on.
