I led a small group of birders on a weekday Audubon Naturalist 
Society trip this morning in Montgomery County, starting at 
Pennyfield Lock.  Migration was really quite slow, and (with the 
exception of the Yellow-rumps) all the warblers encountered were 
local breeders like Parula, Yellow-throated (heard but not seen), 
Prothonotary (several seen very well), Louisiana Waterthrush, and 
Common Yellowthroat.  Best birds were a well seen, singing 
YELLOW-THROATED VIREO, a singing first year male Orchard Oriole, and 
a GREAT CRESTED FLYCATCHER.  We had at least a dozen Green Herons.

Part of the group then moved out to Hughes Hollow, where we saw the 
previously reported COMMON MOORHEN right away, in the company of 5 
American Coot in the first impoundment on the left.  Along the dike 
between the two impoundments on the right we had 3 White-eyed Vireos 
and a pair of Warbling Vireos.  Before we left Hughes Hollow we had 
splendid, extended views of a NORTHERN WATERTHRUSH that was singing loudly.
