The 8th North American Duck Symposium took place in Winnipeg, Canada on August 26-30. This year's symposium was hosted by Ducks Unlimited Canada and the Province of Manitoba, Sustainable Development.

"This symposium only occurs every three years so it's lsquo;the' waterfowl conference and a great venue for presenting and learning about the latest and greatest in waterfowl and wetland science," said Dr. John Coluccy, director of conservation planning for DU's Great Lakes/Atlantic Region. "Researchers attend from as far away as Europe and Iceland. It's a great opportunity to network."

The Symposium is a forum for academics, government and non-governmental biologists, administrators, students and other professionals to learn about the current state of knowledge regarding the biology, conservation and management of waterfowl and foster an open exchange of ideas about the future of waterfowl research and management in North America. Participants present and discuss current research and management issues of ducks worldwide, with the focus on North America.

The vison of the Duck Symposium "is that well-trained and well-informed educators, researchers and managers will ensure that effective management and conservation efforts sustain quality duck habitats and populations for wildfowling and other societal benefits today and for future generations."

This year's symposium addressed this vision by providing a wide range of plenary presentations, including: Assessing and Adapting Human Dimensions; Ecosystem Services and Future Funding; Climate, Migration & Winter Distribution Changes; and Harvest Dynamics and Management. These sessions, along with a full complement of additional oral and poster presentations, provided excellent opportunities for attendees to network and share diversity of thought.

"Given that Ducks Unlimited uses science to guide our conservation efforts, the Duck Symposium is a great opportunity for conservation staff to seek new collaborations, acquire knowledge to aid their efforts, and provide a venue to present Ducks Unlimited research and program activities," said Dale James, director of conservation planning for DU's Southern Region. James gave a plenary presentation on advancing waterfowl conservation through ecosystem services.

Nearly 40 different presentations were provided by Ducks Unlimited, Inc. staff and or supported collaborations, including plenary presentations by DU Chief Scientist Tom Moorman, DU Sr. Science Advisor Dale Humburg, DU Director of Conservation Planning Dale James, DUC Chief Conservation Officer David Howerter, DUC Research Scientist Pascal Badiou and DUC Research Scientist Lauren Bortolotti.
