On the last weekend evening, when I waited for a traffic light at an intersection a little away from the center of Fukui City, there were unusually many starlings all around. Because such a lot of birds had been gathering, the cry was quite loud. And it also requires too much effort to clean up bird droppings.
Large flocks of starlings were in the city center before, but I haven't seen them recently. It seems that the measures that Fukui City has been doing since five years ago are effective. So my guess is that they moved a little away from.
Anyway, it is interesting to hear that a traditional falconer was the most effective measure they have tried. Also, I think it is nice that the report did not treat birds just as villains but said about the good aspects of birds. They eat harmful insects of fields and street trees.
