I just heard from Mikey Lutmerding who found an adult CONNECTICUT
WARBLER at Governor Bridge Natural Area in PG County this morning. If
you walk east from the parking lot towards the canoe launch there will
be a path that goes off to the left a short distance and ends at a
fence that borders Governor Bridge Road. The bird was along that path,
near the fence.

More about the park can be found here:

Good luck!
