Pigeons are not only persistent birds but also, they are carriers for disease. Do not believe everything you read! First and foremost, a gigantic bird statue or scarecrow will not work. This is an ineffective method to control pigeons.

A balcony is a small open-air ledge attached to the side of a building above the ground floor and accessible from within the building. Many balconies have only enough space to allow one person to stand; others are large enough to hold furniture and several people. Most balconies are surrounded by railings to prevent those using them from falling.
