As Feral animals
* Since they reproduce so quickly, they became harder to control. The lack of natural predators and the continued supply of food from bird feeders and seeds, fresh water, and breeding sites in the ledge, rooftops and buildings have made them dangerous feral animals. They are common sites in urban areas such as squares in London and New York City.
* If not controlled, feral pigeons can cause damage to buildings and concrete structures because of their droppings. Their droppings or bird poop is acidic and corrosive to metal and concrete surfaces.
* Pigeon poop is not only unsightly but carries disease risks due to its microbial content. Transmissible diseases include Candidiasis a vaginal and mouth infections, histoplasmosis – a lung disease, E.coli, St.Louis encephalitis which brings fever, headache and cryptococcosis which is a nervous and pulmonary disease.
