I visited three of the Washington County wetlands today, but spent most of my time at Fernhill (Birding Oregon p.61). Nesting species were present in abundance, but overall species diversity was pretty low.
The duck at the top of this picture is a Gadwall, a rare breeder in western Oregon, with her newly hatched brood. The duck at the bottom is a Mallard with her larger duckling. We are quickly entering the “ugly brown duck” season, when all the waterfowl are molting and looking increasingly similar.

Killdeer were the only shorebirds present today. Migrant shorebirds should start appearing in about two weeks.
