Flocks of feral pigeons have become an increasingly common sight in many towns and cities. They thrive in urban areas in particular because there is usually a good food source and due to the absence of predators. The result is that they can become pests in built up areas.
Feral pigeons build their nests in or on buildings and other structures like bridges. Fouling on these structures is inevitable. This is not only unsightly but may also have a destructive effect as the acidic droppings can erode the surface of stonework. Gutters and drainpipes may become blocked, leading to flooding and associated problems. Millions of pounds worth of damage is caused each year to civic and other buildings from feral pigeon droppings.
Feral pigeons carry diseases that are harmful to man, significantly more than the brown rat and yet people wouldn’t normally dream of feeding rats! The best known disease passed from bird to man is Psittacosis but over 40 more diseases can be passes from feral pigeons to humans, including potentially infectious diseases such as Salmonella and Ornithosis.
These birds are also a source of allergens, which can cause respiratory illnesses like pigeon fancier’s lung and allergic skin reactions. It is possible for these illnesses to be spread to people through contact with pigeon droppings, feathers, pigeon parasites, or where dead infected pigeons get into food and water sources.
The presence of pigeons or their droppings (particularly when wet) can also contribute to pedestrian and driver accidents on pavements and roads. |
