Jim, I wish to express my appreciation and thanks to you and everyone who has put in so much time and effort in attempting to verify the identify of this bird. I'm sure we all have our own opinions, but although I saw the bird in question, there is no check on my life list for Common Gull. Perhaps some day there will be, but not with this particular bird. Thanks again to everyone. Paula Ecker Columbia, MD Paulae2156@aol.com
