Some people mentioned that the gull in flight looked serene, Well this is "the rest of the story." The guys would fly at me and then drop below the level I was on. Curious I got out of the car ( I really should change my tag to @carshooter as a good many of my shots are taken as I sit in my car .) And there I saw them below me with tasty morsels in their beaks. Some kind of crustacean that probably burrow in the sand when the tide rolls out and comes out hoping to find food when the tides roll in. Unfortunately the gulls know of these and the hunters become the hunted. I swear I heard some crunching.
