Environmental Impact of Nuisance Birds


Source: Cochrane & Associates, LLC

The environmental professionals at Clark Seif Clark (CSC) provide comprehensive investigative and sampling services to determine if nuisance birds are causing health risks for building occupants and damage to property.

The unwanted presence of birds can lead to not only unpleasant things such as bird droppings, but they can also lead to unhealthy situations.  Nuisance birds, including pigeons, starlings and crows, can create situations that expose building occupants to over 60 diseases attributed to birds.

Diseases include bacterial, viral, mycotic and protozoal afflictions and include everything from Salmonellosis to Meningitis.  Building occupants can become infected through food or water contamination from bird feces, inhalation of contaminated dusts, transference by parasites (fleas, ticks, mites and other ectoparasites) and through direct contact with feces.

In addition to direct health concerns associated with nuisance birds, their presence can also lead to structural issues and other hazards.  Bird nests, droppings and other remnants can accumulate on roofs and alter watershed properties and even result in roof collapse.  Blocked ventilation systems can cause carbon monoxide poisoning and can reduce the life of HVAC systems.  Bird nests located near electrical lights and other fixtures can trigger fires. And acidic bird droppings cause the corrosion of building materials.

Clark Seif Clark, a leading provider of environmental and building science services, has extensive experience working with building owners and property managers to evaluate nuisance birds and find solutions.  “Bird droppings and carcasses are unsightly to almost anyone, but most people don’t recognize the prevalence and extent to which these animals present both health hazards and property damage.” reported Derrick A. Denis, V.P. Indoor Environmental Quality at CSC.  “Too often the nuisance bird wake up call comes in the form of a roof collapse, three feet of accumulated guano in an air handler, or an infected building occupant.”
