Pigeons (Columbia livia), also known as rock doves, typically have a grey body with a whitish rump and red feet, and weigh an avaerage of 13 ounces. They feed on grains and seeds, but also will feed on garbage, insects, fruits, and vegetable matter in urban areas. Pigeons can roost or nest on any man-made structure such as, rooftops, under bridges, on building ledges, and under canopies. Pigeon droppings cause excessive damage to property, machinery, automobiles, and buildings. The droppings increase the destruction of buildings and can also kill vegetation. Pigeons carry numerous diseases that can be transmitted to humans such as; histoplasmosis, cryptococcosis, toxoplasmosis, pigeon ornithosis, encephalitus, and salmonellas. Critter Control uses more than one approach to eliminate nuisance birds from an area and also manages the clean-up and eradication of ectoparasites from the feeding and nesting sites.
