We had a seven duck day! (7 kinds of ducks, not just 7 ducks, LOL!)
1. Two male hooded mergansers and a female. One of the males is shown here with the ubiquitous Canada geese.
4. A better view of the gadwall male.
In addition to the ducks pictured, there were also Mallards (of course), a couple Pintail and many green-winged teal (ducks #5, 6, 7).
And of course, a great blue heron and a few ring billed gulls. The Tundra swan is pictured below.
