Most of the warblers had pulled out of Rockburn this morning. There were still a good selection of residents and a nice smattering of migrants. The best bird was a BAY-BREASTED warbler, seen by the whole party. BB CUCKOO was heard and GREAT CRESTED FLY (both missed yesterday). SWAINSONS THRUSHES were easily seen on the upper oak hillside. A SWAINSONS was also singing behind my house this morning at 6:00 a.m. Bonnie Ott (Ellicott city)
