They make their nest mostly on high rise area and in any premises. Male and female attending mating after those female lay eggs normally 1 to 2 eggs at a time. After hatching the new born will be nourished by parents, normally they get separated from parents after 4 weeks. Breeding occurs throughout the year, favorably in March and July. Now day’s pigeons are disturbing the normal life of human being and causing and transferring so many diseases. Contact with pigeon droppings may pose a health risk. Three human diseases are known to be associated with pigeon droppings: histoplasmosis, cryptococcosis, and psittacosis.
1.Psittacosis- (also known as ornithosis or parrot fever) is a rare infectious disease that mainly affects parrots and parrot-like birds such as cockatiels, and parakeets, but may also affect other birds, such as pigeons. When bird droppings dry and become airborne people may inhale them and get sick.
2.Cryptococcosis- is another fungal disease associated with pigeon droppings and also grows in soils throughout the world. It is very unlikely that healthy people will become infected even at high levels of exposure. A major risk factor for infection is a compromised immune system. According to the US Centers for Disease Control (CDC), nearly 85 percent of cryptococcosis patients are HIV-positive.
3.Histoplasmosis-is a disease caused by a fungus, which grows in pigeon droppings. It also grows in soils and is found throughout the world. When cleaning droppings a person may breathe in some of the fungus, which in cases of high exposure can cause infection. Common activities, such as cleaning off windowsills, will not result in high exposures.
PIGEON PROOFING MEASURES: Avoiding entry of pigeons is a challenging task, now days so many techniques are available for this like Netting, Spike Fitting.
