Phyl, love your pics of the pelican and double crested cormorant pal (I think the black bird behind is a cormorant)
About my pic of brown and white duck -- not a Northern shoveler, see pic. They are large and have a huge bill and no white cheek patch.
More pics from AllAboutBirds of the buffleheads -- one an immature male, but would this be the season to see immature ducks at the Flyway? Buffleheads are very small ducks. I still think the one I saw is a female bufflehead.
