Wow, this sems two more pitfall pictures to me:
first seems to be Grey Plover, eating something, isnt it?
second seems a Great-black backed Gull with an dirtened head to me.
Conclusion? More pictures please or better: Steve Clifton and others, please help: I am not in pitfall picture mode, today!
Edit: after a second look, I am quite sure its not a Gull? I am puzzled, Eider, Oystercatcher. I am sure, I am missing an important thing here, again.
