Sea Duck Joint Venture
Sea ducks are a large group of waterfowl that, relative to other waterfowl species, we know little about.
Some sea duck populations are declining or have lower numbers than they did historically, and they depend on sensitive coastal, arctic, and boreal habitats throughout the continent.
About the Sea Duck Joint Venture
We are a bi-national conservation partnership of organizations committed to maintaining sustainable populations of North American sea ducks throughout their ranges.
We promote the conservation of North American sea ducks through partnerships by providing greater knowledge and understanding for effective population and habitat conservation and management.
