Hello,
No Ash-throated Flycatcher (the one reported on eBird yesterday) and I met another birder friend while he was leaving and said he hadn't encountered it either.
Next to the west end of the boardwalk, there was some Nelson's Checkermallow blooming. In the field next to the parking area, across the street from Oxford Circle, there is a patch of Rosy Owl's-clover blooming (about 40 feet from the curb). There's also a lot of Bare-stem Lomatium blooming there (Lomatium nudicaule - not pictured)
