As it turns out, I DID hear an ALDER FLYCATCHER at Hughes Hollow this morning.   As you walk out between the impoundments, the first right leads to the woods edge.  There, near the woods edge, I heard it.   Someone told me about it and, as I walked toward where it was reported, I heard it call twice but could not locate it.   

A NORTHERN WATERTHRUSH was in the swampy section of woods just beyond.  The VIRGINIA RAIL was still calling at 11:30.

Also heard on Hunting Quarter Road was an ACADIAN FLYCATCHER.

At Riley's Lock, there were two PROTHONOTARY WARBLERs at a nest box.  :-)
