Thanks for the help Rick. I know of a place in Ohio (my old birding "stomping grounds") near Dundee where I had 5 calling HENSLOW'S SPARROWS in one field. It'll be new territory for me, by I hope to pick up SEDGE WREN in Minnesota the second week of June. If I find either one in Maryland, I'll be sure to post the sighting immediately <grin> Greg Miller, Lusby, MD
