David Gerston, Jim Lemert and I toured the Ridge, Maintenance Yard and  
Nature Center  at Rock Creek Park this morning.  We saw or heard 16  
warblers---first spotted mostly by David---and 53 species total. There  
were far more birds singing than we could spot. It was also a nice  
morning for Thrushes and Tanagers.
