Missed the fishy

Ring-billed gull bobbing to the surface after plunge-diving

Not all the gulls were missing; a number flew by will small silvery fish and several other hopeful gulls in pursuit.  (It's apparently tricky to flip a fish around in your beak to achieve the proper head-first position for fish-devouring while you're flying, because some gulls do drop the fish; the pursuers are presumably hoping to encourage a flub and a dropped fish, because then it might be their fish.)

And they weren't too keen on trains, but that's a different picture.
