Had quite a few warbler species on a beautiful morning at the National Arboretum.  All were on the azalea hillside, working a pretty small area.  American Redstart (2), Worm-eating, Canada (2), Ovenbird, Black-throated Blue, Chestnut-sided (3), Black and White, Black-throated Green, Blue-winged, and Blackburnian.  Otherwise, not much else, except Pewee, Red-eyed Vireo, and Baltimore Oriole.
