Black-necked Stilts and American Avocets. We also added Stilt Sandpiper, Bufflehead, House Wren to the list. Total trip count, 71 species.

Notable misses: Pigeon, woodpeckers, and who knows what else! :o)
I'm not including above the usual suspects that would be found in a woodland setting.
It's fun to experience what you see and don't see year-in year-out.
Frustrating sometimes, sure, but oh what fun!
