Crow and Raven
Large, intelligent birds that damage roofing, sealants, and wiring at industrial and utility sites.
How to identify
Large, all-black birds with heavy bills. Ravens are noticeably larger than crows, with wedge-shaped tails and shaggy throat feathers.
Why it is a problem for commercial facilities
Crows and ravens drop debris on roofs, peck out sealants around windows and roof seams, and strip insulation from wiring.
Protected status
Federally protected under the Migratory Bird Treaty Act (MBTA). Birds, active nests, and eggs cannot be harmed or disturbed without a U.S. Fish and Wildlife Service permit. Deterrents and exclusion installed before nesting do not require a permit.
How BSI controls it
- Electrical track on ledges and roof edges
- Bird spikes on fixtures and signage
- Bird exclusion netting for storage areas and open structures
Where we see it most
Commercial and industrial, Municipal and government.
Common questions
Are crows protected?
Yes. Crows and ravens are covered by the MBTA, so control focuses on deterrents and exclusion rather than removal.
What stops crows from damaging rooftop equipment?
Electrical track and spikes on perches, combined with netting where equipment is enclosed.
