April 30, 2009 Except for a few Cape May Warblers heard recently, until today I hadn't encountered any of the northern warblers that pass through in spring. This morning, though, I did hear a singing male Blackpoll Warbler in Greeneville as I drove to work. Warbler numbers are down in the areas I have visited since late March. So far, I have had no waves, and many species are running later than usual. Don Miller Greeneville, Greene Co., TN
