What are pest birds?

While there are thousands of bird species, there are only a few that are typically considered pest birds. They are not federally protected and are not native to the United States. These include pigeons, sparrows, and starlings.

Pest birds are a nuisance. They are considered an invasive species and overpopulate many types of areas. Though they are not considered an immediate threat to humans, they can carry harmful diseases.

Pest birds can also cause serious damage to properties from both their droppings and their nesting materials. They are considered bad for the environment as they can push other beneficial birds out of the area.

Common pest bird species

Pigeons are considered to be the number one pest bird in North America. This pest bird takes advantage of structures and human behaviors when it comes to finding food and shelter.

European house sparrows are competitive birds. They have a wide diet and high levels of reproductivity, making them significant pests.

Starlings are well-established across the United States. They have been known to cause problems for both structures and livestock, resulting in a lot of damage around commercial buildings, fields, vineyards, and power structures.

Starlings are common winter birds.

Crows and ravens are known for their intelligence and adaptability to urban environments. These birds often take advantage of human food sources and sheltered areas, causing issues in both residential and commercial spaces.

Canada geese are adaptable, aggressive and highly unwelcome – especially when they settle in urban and suburban areas.

What you need to know about pest birds

Lifecycle

A bird’s life cycle includes multiple stages: eggs, nestlings, juveniles, and adults. Depending on the species, pest birds can live anywhere from 3-10 years. Starlings and sparrows have an average lifespan of about three years, whereas pigeons can live anywhere from 6-10 years.

In many bird species, eggs typically hatch within 10-20 days, depending on temperature and the species. Nestlings are then fed by their parents until they are ready to fledge, or leave the nest, often within 15-30 days. Juveniles develop rapidly, acquiring essential foraging and survival skills during this phase, which is critical for species like sparrows and starlings, known for their rapid adaptability to urban environments.

In their adult phase, pest birds such as pigeons, starlings, and sparrows often live in densely populated areas, drawn to reliable food sources and nesting locations. This proximity to human structures can lead to significant structural and health concerns. For instance, pigeons’ acidic droppings can corrode building materials, while starlings and sparrows can introduce mites and pathogens into human habitats.

Nest

Pest birds’ nests can cause serious damage to properties because of where they are placed. Their nests and nesting materials can clog pipes, cause electrical outages, and can even attract other insect pests to your property. Pest birds are also very protective of their nests and can become aggressive if a human goes near one.

Their nests and nesting materials can clog pipes, cause electrical outages, and can even attract other insect pests to your property. These birds are also very protective of their nests and can become aggressive if a human goes near one.

Feeding

Pest birds will feed on anything from human food to trash. Pigeons enjoy any type of human food, but prefer grains like sparrows. In addition to grains, sparrows will eat fruits, vegetables, and flowers, but they will also dig through trash. Starlings enjoy trash and spilled foods as sparrows do, but they will also feed on fruit, seeds, and grubs.

Birds like pigeons, sparrows, and starlings have highly adaptable diets, allowing them to thrive in urban environments. Pigeons, often found around public spaces, rely heavily on discarded human food, which can lead to large flock gatherings and greater contamination risks for areas like parks, sidewalks, and outdoor dining areas. Sparrows are known for their opportunistic feeding; while they favor grains and seeds, they’ll readily forage in garbage bins and on sidewalks, increasing the spread of disease and parasites.

Starlings, with their omnivorous diet, can be particularly problematic for gardens and agricultural areas where they consume fruits, seeds, and insects, impacting both property owners and crop yields. All three species contribute to sanitation issues, as their droppings, mixed with food remnants, attract insects like flies and cockroaches, posing additional health and maintenance challenges for property managers.

Diseases carried by birds

Birds are known to carry a range of diseases and are hosts to other insect pests. Humans can also develop symptoms similar to influenza from the spores from bird droppings. Some diseases associated with pest birds are:

Salmonella - This bacterium is deposited where pigeons or gulls defecate. It can lead to Salmonellosis and Paratyphoid fever.

Psittacosis - Also called Ornithosis or pigeon fancier's lung, this infection can be transmitted by inhaling the bacteria from dried droppings or handling feathers of infected pigeons or seagulls.

Fowl pest - Known also as fowl plague or Newcastle disease, this virus can be transmitted to people when they’re exposed to fecal matter and other excretions from infected pigeon birds.

Escherichia coli (E. coli) - This disease is mainly spread by seagulls and can lead to illnesses such as gastroenteritis and septicemia.

Fungal infections - Includes Histoplasmosis and Cryptococcosis. These infections are carried within bird droppings from seagulls.

What you need to know about pest birds

Commercial bird control

For businesses, a bird infestation can lead to maintenance challenges and health concerns, especially when birds choose to nest on rooftops, in HVAC systems, or near food storage areas. Pest birds such as pigeons, sparrows, and starlings are known to target commercial sites where they find food and shelter easily. Recognizing the common signs can help prevent costly issues.

Common nesting spots

Birds in commercial spaces often build nests in hard-to-reach areas, such as behind signage, on ledges, and within roof structures.

Pigeons and sparrows particularly favor protected spots that provide shelter from the elements. Large clusters of nesting materials, droppings, and feathers near these locations may indicate the presence of an infestation, signaling the need for immediate bird control solutions to prevent structural damage.

Commercial property inspection

Regular inspections are essential in identifying bird activity early on.

Observing where birds tend to nest and taking preventative measures can help protect your home.

Where do birds nest in homes?

Common nesting spots in residential areas include chimneys, attic vents, gutters, and porch rafters. Birds like sparrows and starlings seek sheltered, secluded spots close to food sources. 

Finding clusters of twigs, feathers, or droppings around these areas can be a clear indication of nesting activity. Prompt removal and preventive measures can help ensure that these nesting behaviors do not lead to damage or health risks.
