Due to their importance as a game species group, coupled with international conservation emphasis, waterfowl include some of the most studied and intensively managed populations in the world.  Waterfowl in North America are managed by four administrative “Flyways”, partnerships among state, provincial, and federal wildlife management agencies and other organizations.  Washington is a member of the Pacific Flyway

In Washington, waterfowl find both attractive nesting and wintering areas.  At least 24 species of waterfowl breed and nest in Washington, and at least 32 species can be commonly found in the state during fall and winter.  Areas such as the Columbia Basin, Skagit Valley, and the Lower Columbia River are all considered world-class waterfowl hunting and viewing destinations.  Additional information about ongoing WDFW waterfowl management activities can be found at WDFW's Waterfowl Game Species Website.

For over 60 years, our agency has been collecting and analyzing waterfowl management  information from banding and marking programs.  Since 1990, advancements in satellite telemetry technology have allowed waterfowl managers to obtain important new information about movements of birds throughout their life cycles, including  waterfowl habitat use throughout their range.  WDFW has coordinated two major studies utilizing satellite transmitters on waterfowl since 2002, yielding valuable new movement information about scoters and Canada geese.
