Black-throated Gray Warbler continued this morning (Monday) for about 15 minutes starting at 10 a.m. at Noel Dorwart Park west of Lancaster, PA. This male was working back and forth across the Little Conestoga Creek along the "goat path". This is referencing the narrow dirt non-improved path that begins at the lower end of Trestle Spur Trail at the creek. Walk upstream along the path. The bird was seen with White-throated Sparrows and Kinglets.
