On this crisp Sunday morning some 30 birders witnessed a splendid  
warbler fall-out on the RCP Ridge and Equitation Field. In addition  
the Philadelphia Vireo made an appearance, much to the pleasure of  
Carter Roberts who added this to the last three remaining  
unidentified birds on his life list of North American birds---the  
bird was spotted by Dave Bolton.  The Olive-sided Flycatcher was a no- 
show.  The following warblers were seen:

Bay-breasted
Northern Parula
Black-throated Green
Black-throated Blue
Chestnut-sided
Blackburnian
Black-and-white
Magnolia
Nashville
Blackpoll
American Redstart
Common Yellowthroat

Others:
Sharp-shinned Hawk  (Yard)
Scarlet Tanager

On his tour of  the Dog Run, Mike Bowen looked up to see 10 Broad- 
winged Hawks and a Harrier.  The Maintenance Yard was quiet.

Have fun birding!
