Trip to the river in Harford County for resident Cerulean and Prothonotary Warblers and a collection of spring migrants. This is one of the best spring warbler watching sites in Maryland; 18 to 24 warbler species possible in a single day. Paths are uneven, unpaved and some are hilly. Meet at the lot at the end of Rock Run Rd., next to the old mill building. RSVP to leader required.
