Sea Gulls and Their Beach Look

Sea gulls on the beach always face in the same direction. The reasoning behind their group look is that they need to face the wind so that their feathers won’t be ruffled by a back wind. The real mystery for me is why do they stand so close to the surf, often having to take flight to avoid a wave?But when they do go in the air, they usually return to the same spot and repeat the process. Waiting for food to roll in? Or, maybe they’re just having fun.
