Feral pigeons are descendants of the rock dove of Europe, Asia and Africa. The pigeon was first brought to this country as a domestic bird in 1606 and is now found in the wild state in virtually every city.
Pigeons take on the status as a pest when they conflict with human activites or present health problems.
Pigeon droppings deface and accelerate deterioration of statues, buildings and equipment and foul areas where people may walk or work.
Pigeon droppings and nests clog drain pipes and air intakes, mar window sills and make fire escapes dangerous. The droppings and feathers can contaminate large quanities of livestock feed and food destined for human consumption.
Pigeons are known to carry or transmit pigeon ornithosis, encephalitis, Newcastle disease, histoplasmosis, cryptococcosis, toxoplasmosis, pseudo-tuberculosis, pigeon coccidiosis and salmonella food poisoning. Pigeon parasites include a number of bugs, fleas, ticks and mites, many of which bite people.
Pigeons are monogamous, mating for life. Wild pigeons can live for 15 years or longer, while pigeons in an urban environment seldom live more than three to four years.
The pigeon diet consists of seeds, grains, some fruit, and green feed. They also feed on garbage, livestock manure, insects and a wide range of other foods.
