Buffleheads are one of my all-time favorite ducks.
It was one of the first ducks (besides Mallards) that I learned to
identify.
They are a North American bird.
They breed in Canada and Alaska and winter mostly in the U.S.

The males are easily recognizable with the greenish-black heads with the
white cap.
The females have a white patch behind the eye and a brown head.
Buffleheads are divers and will forage underwater.
They eat insects, crustaceans, plants, and fish eggs.
Buffleheads winter in the S.F. Bay Area.
