Birding at Rock Creek Park started out slow but picked up around  
8AM.  Mike Bowen, Jim Lemert and Lou Demouy remained at the Ridge  
while Dan Eberly and I went to the Maintenance Yard.  Their  
persistence at the Ridge resulted in seeing a nice wave of birds as  
follows:

Parula 2
Magnolia Warbler 3
Blackburnian Warbler
Black-throated Green Warbler 2
Blackpoll Warbler
American Redstart 5
Black-and-white Warbler
Red-eyed Vireo
Scarlet Tanager 2
Rose-breasted Grosbeak 2
Wood-Pewee
Phoebe
Red-breasted Nuthatch (heard)

At the Yard, Dan and I were later joined by Jim and Mike. We saw:

Parula 2
Magnolia Warbler 2
American Redstart 3
Black-and-white Warbler
Tennessee Warbler
Common Yellowthroat 4
Philadelphia Vireo
Acadian Flycatcher
Phoebe 3

Have Fun Birding!
