I think it is highly variable depending on exact location. I have seen a bunch of Green Wing Teal this spring, and there are lots of shorebirds ( Avocets, Stilts, Phaloropes, dunlon and sandpipers, sometimes white-faced Ibis)) at Clover Island and the Millet Ponds at Wallula in the spring but I don’t see them in fall.It is interesting to me how the migration patterns vary as far as what shows up in spring vs fall. I never see shorebirds in the spring, but get a variety of sandpipers, yellow legs, etc. in the late summer. Cinnamon Teals and Shovelers are spring only, but Green Wing and Blue-winged Teals only appear in the fall. Wood Ducks can be either. Anyway, today a couple pairs of Shovelers decided to spend the day resting here.View attachment 110415
