Pigeon habits and preferences
Pigeons are most active in their feeding in the morning hours. They are happy eating anything from seeds and grains to human garbage. Natural scavengers, pigeons have survived well in urban environments due to their willingness to eat just about anything that they can find. Pigeons will generally nest or roost in areas that are protected from the elements and from people. Pigeons preferred nesting sites are on top of HVAC systems, loading dock and garage ledges in commercial settings and on rooftops under the eaves where two rooflines meet in residential settings. While a wild pigeon may live up to 15 years, most urban pigeons will only live 3-4 years.
The chief concern with regard to pigeons lies in their droppings, which can carry many diseases. Pigeon ornithosis, encephalitis, Newcastle Disease, cryptococcosis, toxoplasmosis, and salmonella have all been linked to pigeon droppings. The droppings are highly acidic, and can also cause damage to structures over time. Pigeons themselves can also carry dangerous parasites, including fleas, mites, lice, ticks, and other biting insects. When pigeons choose to nest on residential homes, they can potentially subject homeowners to these problems.
Biology of Pigeons
The feral pigeon is the most common urban pest bird in the world. The standard pigeon has a short neck with a proportionally small head. They also have very short legs, which are ideal for perching themselves on trees or branches, as well as quick movement on flat surfaces life rooflines. In general, pigeons stand about 12-15 inches tall, and weight about one pound. While usually a bluish-gray color, they can also vary in appearance from white to gray or brown.
Pigeon Control Measures & Prevention
Pigeon control methods tend to vary based on the extent of the infestation and the individual circumstances surrounding the structure. When pigeons are nesting in covered or sheltered areas, exclusionary netting may be applied to keep them out of those areas. Because pigeons are so fond of roosting and standing on ledges, there are specific ledge deterrents such as spikes, bird wires, and electrical shock strips that can be used to keep them from causing damage to the structure. Depending on the circumstances , trapping and baiting can also be done within the confines of an approved bird control plan.
