Managed to stop by for an hour at Panama Flats after work on Thursday evening. Nothing much had changed, with the exception of the further diminished water levels.
There were still around 60 small waders present, again the majority being least sandpipers and western sandpipers. I could only find one semipalmated sandpiper today (pictured) in among a group on the NW quadrant.
There were 2 greater yellowlegs and 1 lesser yellowlegs moving around the place. A single dowitcher sp. was present again, but remained silent.
I couldn't see the solitary sandpiper anywhere, but there were 3 or 4 unspotted juvenile spotted sandpipers creeping around. I only checked the SW and NW quadrants, so it may have been elsewhere.
