Yeah, it perched on something. In direct sunlight. Cheers.
In flight windows and things. You still reading this?
Close up! More inconclusive imagery.
In flight chase sequence! Again, not helping much with the ID.
It's the one on the right by the way.
So there we are. No real new clues to nail the identity. I'm sort of veering away from the washed out LBB theory but without some more salient ID features (wing projection, orbital ring, close comparison to an equally aged Herring, good gawp at the bill etc etc - some of which may not be clear until the primaries poke through) this gull stays firmly in the 'dodgy pile'.
