The Working Group for the Anatidae Site Network in the East Asian Flyway was established in May 1999 to oversee the implementation of Action Plan for the Conservation of Migratory Anatidae in the East Asian Flyway under the Asia Pacific Migratory Waterbird Conservation Strategy. This working group then took on the role of supporting of the Partnership.

The goal of the Anatidae Working Group is to coordinate, facilitate and promote collaboration on Anatidae conservation, management, education and research activities, across the East Asian-Australasian Flyway. The Working Group covers species under the Anatidae taxonomic group (ducks, geese, swans).
