I was at Conowingo Dam this morning from 9 to 10 am. All of the generators were running but there were no flood gates open so the conditions were very good for gulls. My wild ass guess is about 20,000 gulls present. Most were ring-bills with a respectable number of Herring and Great Black-backed present. I did manage to find one Lesser Black-backed and 2 Bonaparte's (or the same one twice) gulls. I am sure there are other rarities present but I have neither the expertise or the patience to find them.
