I had a flock of at least 25 bobolinks at 7:20 PM on 5/6 at Cromwell Valley Park, Baltimore County. Directions: From the Willow Brook Farm entrance, park in the main parking lot. Walk back across the bridge and take the stream path to the right. The birds could be in any of the fields between the stream and Cromwell Bridge Rd. Tonight they were almost to the Sherwood Farm road. Last year bobolinks were at Cromwell Valley at the same time, and stayed at least a few days. Peter Lev Towson, MD
