I encountered a few warblers on the azalea hillside this morning at the National Arboretum:  BLACK AND WHITE, BLUEWING, OVENBIRD, CANADA, CHESTNUT-SIDED (1st winter.), and AMERICAN REDSTART (m & f).  One of each except for the redstarts.  There were several pewees throughout the grounds, a great-crested flycatcher, red-eyed vireo, blue-gray gnatcatchers, kingbirds, catbird, and a ruby-throated hummingbird.
