My father does the same thing in France. He can't stand the noise seagulls make so he shoots them with a pellet gun. It doesn't seem to harm them very much and is very effective. He does it a couple of times at beginning of the season and then a couple more times during late spring/early summer and they don't come back, or at least the circle around the property. Birds aren't as dumb as we think.
