Which method is commonly used to disperse birds of prey to protect airports?

• A. Ultrasonic Deterrents
• B. Falconry
• C. Netting
• D. Chemical Sprays

Answer: (B)

Dispersing birds near runways relies on using a natural predator to influence bird behavior. Falconry employs trained raptors to actively patrol the airfield and chase away other birds. The presence of a trained hunter signals danger to smaller birds, which causes them to avoid the area, reducing bird activity around runways and approach paths. This method is flexible, can be deployed quickly, and provides immediate, non-lethal deterrence with relatively low environmental impact, often as part of an integrated wildlife management plan.

Ultrasonic deterrents are generally ineffective for birds, as birds may not be deterred by sound or can habituate over time. Netting is useful for protecting specific assets but impractical for large open areas like runways. Chemical sprays pose environmental and safety concerns and are not a practical or reliable deterrent for airfield-wide bird control.
