I saw a White-Crowned Sparrow this AM at the New Wegman's supermarket in Hunt Valley (Baltimore County).  It was in a very small flower bed bordering the parking lot.

Taking this as a sign of sparrow migration, I visited Cromwell Valley Park in the afternoon.  Here I saw a few hundred sparrows, but the best bird was Yellow-Billed Cuckoo (getting late).  Sparrows were:
Song (approx. 150); Chipping (approx. 70); White-Throated (12); Field (9); Towhee (3); Swamp (1).  A Junco in my front yard made this an 8 sparrow day.

Also at Cromwell, a few hawks (add to the Hawk Watch total, Jim!):  Sharpie (2); Northern Harrier (1).  And 3+ Yellow-Rumped Warblers.
