Lesser Great-backed Gull

Despite the temperature being in the 30s, the Sun was shining in the was no wind and I went down to Plymouth, Massachusetts to do some photography. I went to Jenny's pond, where there was a good variety of ducks, including gad walls, quoted mergansers and buffleheads.
Also, there was the perennial lesser Black-backed gull present.. This photograph helps show the differences between the lesser black-backed gull and the greater black-backed gull. The head is streaked, the legs are yellow and the back is more of a dark gray.
