I thought these were harlequin ducks at first. But I did a little research and found that they are wood ducks.
These wood ducks are common in the Siuslaw National Forest rivers.
These males are in their breeding plumage now.
The females even have some of the iridescent green on their wings. It reminds me of the traditional, human, formal attire; where the woman is the colorful one and the man has a touch of the same color on his clothing….just so everyone knows who goes together!
As they were swimming up the tidewater area of the Alsea River, the females would take a detour. Maybe they are looking for a good nesting area? A few of them strayed up onto the bank, softly quacking to each other.

Blackberry Campground is a great place to observe wildlife on the Alsea River!
