Thoughts on this bird? Seen at Eyebrook Reservoir, Leicestershire/Rutland on 11 June. I didn't see it fly off, so no flight shots I'm afraid. It did have a very clean white rump, though I didn't manage to catch this in any of the images.

looks like a 2cy YLG. but to be sure i'd have preferred to see inner wing and tail.

Thanks Lou. I thought the other possibilities were Great Black-backed and Caspian Gull. What points towards ruling them out, would you say? I'm sorry I missed it flying off to get a photo of its tail and wings.

some scapulars are 3rd generation and pale grey (excluding GBBG). bill shape is off for most caspians which can be very similar to 1st summer YLG. too short and too bulbous at tip.
