Is it a first winter Slaty-backed Gull?  Thank you.

It's not Slaty-backed, no. However, do you have more photos? Images showing the bird side-on and in flight would be interesting.

Thank you for your advice.  I have two more photos, but no side-on nor in-flight showing the back and tail.

This gull has been around for a few weeks, joining the two that have oversummered in Deep Bay. It has very pale plumage (whitish) with darker subterminal marks on the upperparts, and on this basis I had thought it was a Mongolian Gull.
I'm slightly confused by age though, because I thought the body looks like a first winter, but the stage of moult does not seem to be correct for that age.

Thank John for the reply.  I have two more photos, but I guess they won't be of any help.
