Laughing Gull (Larus atricilla)
Thank you. Both Laughing Gull photos in the Bird Files were taken at the same time ....... Chincoteague, VA. I had never seen one before until I pulled into a McDonald's parking lot (not to eat), near Chincoteague, because I saw this "different" bird sitting on the top of the Big M sign. Later in the day, I saw lots of them.
