I heard Warbling Vireos twice this weekend; once on Saturday morning while walking the towpath from Pennyfield to Blockhouse Point; and again this morning in my yard before work (Frederick County).  According to the Yellow Book, the early arrival date for the species is April 16th, so it seems a bit early. 

Another global warming phenomenon?
