Joe Chronowski and I went birding in Susquehanna State Park to add Yellow-throated Warbler to his life list. Our first stop where I had one two times this past week was dead. We took a little walk and found a Prairie Warbler (a lifer!). We then returned to the spot for the Yellow-throated and it was there singing away. We then went to Rock Run and had many Parulas, Myrtles, and a few Palm Warblers. Joe had a brief glimpse at a Black-throated Green Warbler. We also had one Black and White, and one Yellow-throated Vireo which were both new for the year for me. There were many Chimney Swifts flying overhead, the first ones I've seen this year. We ended the morning with 9 warblers. Matt Hafner Bel Air, MD
