Pigeon (Rock Dove)
The most common pest bird on commercial buildings, roosting and nesting on ledges, rafters, and rooftop equipment.
How to identify
A medium-sized bird, about 13 inches long, with gray, white, or brown plumage, a stout body, red legs, and iridescent purple and green neck feathers.
Why it is a problem for commercial facilities
Acidic droppings eat through paint, concrete, limestone, and metal roofing. Pigeons nest in steel rafters and HVAC units, clogging equipment, and their droppings can carry pathogens such as histoplasmosis.
Protected status
Not protected under the federal Migratory Bird Treaty Act, because it is a non-native, introduced species. Local ordinances and animal welfare laws still apply.
How BSI controls it
- Bird exclusion netting with 2-inch mesh to close off rafters, canopies, and open structures
- Electrical track for high-visibility ledges and signage
- Bird spikes and ledge slope systems to remove landing surfaces
- Bird wire on parapets and ledges
- Cleanup and decontamination before any system goes in
Where we see it most
Commercial and industrial, Transit, Aviation, Municipal and government.
Common questions
Do I need a permit to remove pigeons?
No federal permit is required, because pigeons are not protected under the MBTA. Local rules still apply, and exclusion is the only lasting fix.
What works best on a warehouse with open rafters?
Interior netting with 2-inch mesh closes the rafter space completely, so birds have nowhere to roost or nest.
