The feral pigeon adapts well to man-made environments and often is the most troublesome bird for structures. Pigeon droppings deface and accelerate deterioration of buildings, statues, equipment and foul areas where people may walk, work or play. The serious and constant public health problems they create are unmatched by any other bird species. Exclusion work can be done for these birds and exclusion products applied. Trapping and Baiting are other forms of elimination.
