Up to 4 different Caspian Gulls (2 adults, a 2nd winter and now a 1st winter) are in the Sheffield area. They are often loafing on a cleared industrial site only 15 minutes walk (4 minutes drive) from my house. So it’s quite a wee Christmas cachinnans fest. Here are 3 of them:
and showing a nice white underwing:

and one I saw the other day that smelt a bit like 1st winter Yellow-legged Gull michahellis)- at least enough to make me look carefully for more details. Unfortunately it was at the back of the flock and stayed sat down, so no other details seen (e.g. wing and tail). I got few seconds of video and left it.
What do you think?
