Most people here seem to hate them. One constantly hears stories about lunch in seaside restaurants ruined when seagulls swoop in a snatch sandwiches or fries right from your hands. I can see how that could be annoying, but I still love seagulls.
We had some very stale, rock-hard bread that has been sitting around for a week or so. Instead of throwing it out, we soaked it overnight and then took it to the beach, where I threw it to the seagulls in little handfuls. There were just a few to start with, but after just a minute or two the sky, first, then the beach was full of them, shrieking and calling. Lots of them were juveniles - perhaps the adults who've survived have learned more and better places to find food.
It was such fun. I almost bought them some chips just so I could keep feeding them, but decided against it.
