Pest Profile: Birds
Birds of all types are an important part of the natural ecosystem. With that said, some species can become problematic when they nest or roost on buildings. Common species of nuisance birds include pigeons, starlings, sparrows, and gulls. When birds establish themselves on or inside structures, they can do property damage and create health risks.

Bird Biology and Life Cycle
Compared to other types of pests like insects, birds have rather long lifespans. The reproductive patterns of birds vary by species, but most will breed once to twice per year. Females typically lay eggs in nests that are constructed from materials like twigs, grass, feathers, and debris. Incubation may range from 10 to 20 days, after which a nestling period will take place before the young birds become independent.
Bird Habitat and Behaviour
Birds that are considered a nuisance are adaptable and can take advantage of man-made structures to create safe nests. These nests might be seen in places like on rooflines, ledges, vents, chimneys, and signs. And, since many bird species return to the same nesting site year after year, it can be hard to get rid of a persistent bird problem.
One of the biggest problems with a bird population is the accumulation of bird droppings. These are unsightly and corrosive, meaning they can damage buildings over time. Certain species, including pigeons and starlings, are social and will roost in large numbers, only furthering the problems that they cause.
Bird Treatment Options
Identifying the species involved is the first step toward getting rid of birds. Treatment options vary by species, and some are protected by law in certain areas. The best way to deal with bird populations is typically by preventing them from setting up a nest in the first place. This means using netting to block access, or sealing vents and chimneys to make sure they don’t get in. If those means aren’t enough, using professional wildlife control services would be the next step.
Bird FAQs
Q: Are birds protected by law?
A: Many bird species are protected by federal or local wildlife laws. It is often illegal to harm birds, remove nests, or disturb eggs without proper authorization.
Q: Can bird droppings cause health problems?
A: Yes. Bird droppings can carry pathogens and accumulated droppings may also contribute to respiratory issues.
Q: Why do birds keep returning to my building?
A: Birds keep coming back because they have found a place that offers shelter, warmth, and nesting opportunities. Only through excluding these conditions will the birds be forced to find somewhere else to go.
