Hi all -- I received a private email from a friend who saw the Slaty-Backed Gull this am at Conowingo Dam. He said it was found at about 7:15 am and was still there when he left to go to work at 8:15. I'll be setting BC to "nomail" as we are heading out again so hope someone else will continue to update that list. Gail Mackiernan Silver Spring, MD gail@umdd.umd.edu
