While up at my place in WV this week, I ventured just over the line into MD, to the Old Town Aqueduct area, a new favorite of mine.  Highlights and favorites of mine below:

Worm-eating Warbler-excellent eye-level looks at one
American Redstart-1 frolicking pair
Ovenbird-2 calling
Black and White Warbler
Yellow Warbler
No. Parula
Common Yellowthroat
both Orioles-many 
Indigo Bunting-many
Scarlet Tanager
Osprey with fish in talons
Flyover Egret-sp?
Flushed a pair of herons-probable Black-crowned Night Herons.  Was in the
pouring rain at this point and unable to get a good look.
