Any chance I could have a hand IDing these gulls in Beijing ? Grainy photos all cropped from a single photo taken today (21/3) at Shahe Lake

The flying bird is adult Mongolian Gull. The others look better for Mongolian Gull than anything else to me, but it's harder to be certain on those images.

Thanks! I was wondering about the hint of a black ring on the bill of the gull in the 3rd pic (the paler gull, presumably 2nd winter?). I wasn't sure if Mongolian/Vega gulls ever got those black rings, so was wondering if juvenile Black-Tailed was possible?

Still one of the larger gulls, probably Mongolian and probably second-winter. Black-tailed Gull has grey saddle by second-winter, but has brighter bare parts by this time also.
