The Nossa Senhora da Consolação church, in downtown Sao Paolo, Brazil, used to have a serious pigeon problem. The pesky birds would fly through the place during sermons, poop on the benches and leave feathers everywhere, but ever since they had these colored circle panels installed in the windows and doorways, no pigeon gets close anymore.
Regular parishioners at Nossa Senhora da Consolação describe the pigeon situation as a “real hell”. Dozens of birds had made the place of worship their home, flying in and out whenever they pleased, making a lot noise during mass and dropping stones and bits of plaster on people. Every morning, the floor and wooden benches had to be cleaned of bird droppings, and at one point it all became too much to bear. The church wanted to find a humane way of driving the pigeons away, but they never imagined hypnosis would be the answer.
