8.06.030 Findings¶
The City Council finds that regulation of pigeons is necessary to protect the public health and safety of City residents and visitors, as evidenced by the following facts.
Over the past eight months, staff has received statements describing the presence of a large number of pigeons in the Sterling Park neighborhood, the proliferation of mites in the vicinity of the property and damage by pigeons to nearby fruit trees. On investigation, staff has observed a significant amount of pigeon manure on otherwise clean vehicles and roofs and windows of residences that are located near to pigeon lofts.
It is common knowledge that pigeons drop feces below areas where they roost and fly. Bacteria and fungi is transmitted from the droppings and respiratory secretions of infected pigeons to humans, leading to infection which in turn can cause liver damage, kidney damage or even meningitis.
It is also common knowledge that pigeons consume fruits, grains and vegetation, especially in
Regulation of Pigeons Colma Municipal Code (January 2006) Page 8.06-1
areas near their nests and attract mites and pests to their locations.
Bacteria are spread from an infected bird in its droppings and respiratory secretions (i.e. sneezing and coughing). The bacterium which homing pigeons (if infected) can spread is called Chlamydiosis. Chlamydiosis, also known as Psittacosis, can be transmitted to humans. In people, the disease causes flu-like symptoms of fever, chills and headache. If left untreated, Psittacosis can cause liver and kidney damage or even meningitis. (This Chlamydia is not the same infectious agent that is spread among humans as a sexually transmitted disease.)
Cryptococcus is another fungus infection. Though uncommon in pet birds, infection can cause diarrhea, paralysis, nervous-system signs and masses with a gelatinous consistency. Humans can contract this disease when they inhale the dust from dried droppings (most commonly from pigeons). Infection in people can be quite serious leading to meningitis, encephalitis (brain inflammation) or respiratory symptoms.
Dryness, cleanliness and proper sanitation in pigeon lofts are essential to the health of pigeons and necessary to prevent the spread of disease. This ordinance adopts standards and conditions for maintaining pigeon lofts to prevent the spread of disease.
Disease can also be spread by allowing pigeons to stay outside of their loft for extended periods of time or to perch on neighboring yards, houses and cars. Pigeons can be trained to not land anywhere except on the landing board of the pigeon owner's loft, from staying out all day, from perching on neighbor's yards, houses and cars, and to return to their loft promptly after release. The risk of disease and nuisance is minimized when pigeons are trained in this manner. This ordinance mandates permit conditions requiring the permittee to train pigeons to behave in a manner that will minimize or prevent the spread of disease. These requirements are based on techniques for training pigeons recommended by the American Racing Pigeon Union, Inc. and are based on the concept that it is a pigeon's love of home, need for food, and fear of the unknown that brings it back to its loft.
Prior to the introduction of this ordinance, staff inspected certain areas near an existing pigeon loft that reportedly contains 50 pigeons. Staff found, on an average day, 30 incidents of pigeon droppings within 75 feet of the loft and an additional average of 20 incidents of pigeon droppings between 75 and 110 feet from the loft. There were higher concentrations of droppings on rooftops and perch areas within 100 feet of the loft. Thus, residences and personal property commonly stored outdoors, such as vehicles and patio furniture, within 100 feet of a pigeon loft are more likely to be affected by the nuisance caused by the consistent presence of pigeon droppings.
Based on the evidence, a set back requirement of up to 100 feet from the pigeon loft to the nearest dwelling unit would be warranted. However, this would result in a complete ban on all pigeon lofts in the residential areas in Town. With the adoption of requirements that pigeons be trained to return to their lofts without perching in the surrounding areas, a less restrictive setback requirement of ten feet is established in this ordinance.
Another health concern is that rodents and other animals are attracted to properties where pigeon food is left out or improperly stored. These rodents will leave feces in areas visited and will carry diseases. For this reasons, this ordinance adopts standards to prevent rodents and other animals from feeding or residing on or about pigeon lofts.

Because of the health and sanitation risks associated with keeping or maintaining pigeons, many of the provisions of this ordinance shall take force and effect on the dates provided herein despite any claims of grandfathered rights under traditional zoning laws. In order to allow persons who were keeping pigeons a reasonable notice and opportunity to comply with certain provisions herein, the provision requiring a permit will take effect approximately 60 days after passage of this ordinance and the provision requiring a reduction in the number of pigeons will take effect on approximately one year after passage of this ordinance.
Finally, feeding of wild animals and birds on public property causes a public nuisance by attracting wild animals and birds which drop feces in the areas where they are fed, which must be cleaned by city crews, at taxpayers' expense.
