Since no one else has posted yet, here are my observations 
from this morning at Rock Creek Park (Maintenance Yard), as 
submitted to eBird.  Highlights included a nice variety of 
thrushes (SWAINSON'S, WOOD, VEERY, and robin of course), and 
a good assortment of warblers (CHESTNUT-SIDED, MAGNOLIA, 
BLACK-THROATED BLUE, BLACK-THROATED GREEN, BLACK-AND-WHITE, 
AMERICAN REDSTART, COMMON YELLOWTHROAT).  Had 2 warbler sp. 
(flashes of yellow flying away), and others saw a 
YELLOW-THROATED VIREO.
