Black-headed Gulls (Lydney boating pool - frozen ice)

 I think that I am getting a bit darker...............

                                                             Yes, I think so.

                          All that thinking makes me want to scratch, ah that's better.

                                                         Let me have a look...........

                                                            I see no ships.......

                                                            nor this way.

 Hey you up there, I am a little bit darker than you.

Oh.......................
