Black-Headed Gull With Winter Plumage
Above you can see a gull, I had to research what kind of gull it is, but I believe it might be a black-headed gull. But the gull in my picture is not black-headed, that confused me when I researched, but it seems their plumage does change depending on the season and if they are breeding or non-breeding. So, if I am right with my research, the gull in my photo is a black-headed gull with winter plumage. You can find a couple of photos in a Wikipedia entry that shows the different plumage appearance. The site All About Birds has a nice entry too, click on the link and you find different photos too.
