(1) Is the gull an immature Glaucous Gull?
(2) Please help ID the bird (?) in the gull's mouth.

The gull is a first-year Black-tailed.  The food item appears to be a tiny, black-legged shorebird, so most likely Red-necked Stint.

Amazing to see that it can swallow the stint whole...Thanks for sharing!

Thank you.  I hope the Spoon-billed Sandpipers know this gull is a bird killer and avoid getting too close to its mouth...

I'm not sure that the gull would actually have hunted the stint. I haven't previously seen gulls making any attempt to catch birds of any sort, and if this happened regularly I think the shorebirds would be scared of gulls (as they are of other predators).
It may be that the stint was very sick or already dead, and the gull ate it opportunistically as a meal.

Thank you, ajohn for your comment.
Interesting though, there was news (Mirror 13th October 2014, entitled "When seagulls attack: Killer gulls caught drowning and eating pigeons") in London (with photos) that a seagull caught pigeons, drowned them, then ate them at Hyde Park.

Thank you, kmatthew.  I was also astonished to see the gull swallowed a bird.
But this photo taken about half an hour after the gull swallowed the bird shows that the gull has a large mouth.

Thank you, wcaptain, for your advice.  I think these big gulls will eat whatever that can be swallowed through their mouths.  I saw some photo on internet that a seagull killed and swallowed a squirrel!
