Nice! I was there today too, and got 69 species. I missed your Snipe, Palms and Rusties, but found a Gnatcatcher in the same area as yours, 1 Black and White, 1 Pine, 4 Dunlin and 8 Yellowlegs (could only identify Greaters by sight and sound, but they took off before I could scrutinize them all).
Other notables were a male Black Scoter, 3 Iceland Gulls, Common Tern, House Wren, and several Thrashers, Field Sparrows and Towhees.
I skipped the bird banding station today because I didn't find anything exciting there last week... is it usually worthwhile?
