Who's got the doughnut? Gull chase!

Black backed gulls (juvenile and adult) chasing a juvenile gull that's picked up a large doughnut! The bird can't swallow it, or get away from the others long enough to break it up - the chase went on for some time heading further out to sea, so I didn't get to see what happened. Probably it got dropped and there would be a free for all in the water till it got soft enough to be eaten.

The beaks are all wide open threatening the bird with the food.
