This weekend around Edgewater, Maryland, I saw the following warblers:

yellow-rumped warbler (one, early!)
Cape May warbler (two)
American redstart (three or four)
yellow warbler (four)
northern waterthrush (one)
yellow-throated warbler (one)
pine warbler (one, in the company of two imm. eastern bluebird)
magnolia warbler (one)
black-and-white warbler (three)
common yellowthroat (one)

Also, a lot of other bird activity, with migrants overhead including 
sev. bank swallows, a number of purple martins, a flock of 22 
bobolinks "spink"ing over, and inflated numbers of apparently 
migrating "locals" such as red-eyed vireo (about 10), eastern 
wood-pewee (10?), and ruby-throated hummingbird (four).

The day before heading out to Edgewater, I saw an immature 
black-throated green and a chestnut-sided warbler in our Bethesda 
backyard--our first fall warblers.
