Feral Pigeons are associated with big cities where they have often become a tourist attraction, such as on the Piazza San Marco in Venice, which cannot be imagined without pigeons. The Feral Pigeon, which is a domesticated form of the Rock Dove, has completely adapted to living in towns and cities. Some pigeon lovers have a very deep relationship to their birds. Due to the abundant food supply and the absence of natural predators, large pigeon flocks can cause problems in many places.
