Every neighborhood has one, a house that the pigeons love. The roof is coated white, with poop, and there entry way is a mess. Mean while the houses right next door have no poop, and no birds. What causes this you ask. I have study birds for many years, and have come to one conclusion..... They let them stay the first time. We have done jobs, where dead pigeons have clogged roof drains, and the weight of the water collapsed the roof, and their poop eats away the roofing materials.
Lately I have had 2 to 3 pigeons hanging around my house, but our neighborhood pigeon house is 2 blocks away. At first I thought they were eyeing a new place to hang, and I am probably right. What brought them in, was a tree of mine just seeded, and rang their dinner bell. So the last few days, I have been throwing rocks at them, and yelling. They fly away every time, but are back in a half an hour. I am going to go suck up the seeds and see if that helps, because this will not be my house.
I will burn it down before it comes to this.
