I made a couple stops today and managed to see or hear five species of warblers. At Evansburg State Park I heard Louisiana Waterthrush, and saw Palm and Yellow-rumped Warblers. A quick hike later in the day at Nottingham County Park in Chester County netted me lots of Pine Warblers and 2 Black-and-white Warblers.
I was planning on getting outside today but the rain may prevent that. It is pretty exciting to see some of the earlier warblers arriving and to look forward to the next wave of migrants.
