And still present around 4-4:15 this afternoon, as the light grew pretty dim.  It was on the far side of the flats with 2-3 ring-billed gulls, definitely a scoper.  Hard to see the bill color, but every once in a while he would lift his wings, and the dark underside of the primaries was clearly visible.
MD Bird # 294.  I may not make 300 by year's end, but it's been fun trying.
