According to the Federal Aviation Administration (FAA) in the United States, various methods are employed by ground crews at U.S. airports to repel birds. Here are nine effective techniques:
Trained Dogs and Birds of Prey: Despite the associated costs, trained dogs are used to deter birds at U.S. airports. For instance, Dallas-Fort Worth International Airport has successfully employed trained birds of prey to chase away roosting birds from parking lots.
Bird Effigies: To address the threat posed by turkey vultures, hanging real or stuffed vultures as bird effigies effectively frighten them away. This method has also proven effective with gulls and ravens.
Grape Flavoring: Gulls have an aversion to grape-flavored drink mix. Airports use this deterrent to discourage gulls from gathering in water pools formed after heavy rains.
Golf Tees: To prevent birds from perching on taxiway light posts, airport personnel attach golf tees with upward-facing points. This modification discourages birds from selecting these posts as their preferred perch, thereby improving visibility.
Plastic Projectiles: Non-lethal plastic projectiles like paintballs, known to cause temporary discomfort, effectively deter large birds such as geese. Airports prefer this method over toxic substances or lethal weapons due to its effectiveness and lower risks.
Remote-Controlled Vehicles: Some airports employ remote-controlled cars and boats to flush out birds. During molting season, remote-controlled boats have successfully corralled approximately 200 geese from lakes and guided them to new locations. The use of unmanned falcon-like aircraft is emerging but limited due to regulations such as the Airborne Hunting Act, requiring advanced training.
Pyrotechnics and Cannons: Fireworks and propane cannons serve as effective scare tactics for birds. However, birds can become accustomed to these methods if used consistently at the same time every day. To maintain effectiveness, a combination of sound-driven deterrents should be employed and varied regularly.
Distress Calls: Broadcasting distress calls to divert birds away from air traffic can yield mixed results, as not all bird species respond to these calls. The efficacy of this method also depends on the time of year. Integration with other techniques is crucial to maximize effectiveness, although potential disturbance to nearby individuals who may find the sounds irritating should be considered.
Handheld Lasers: While handheld lasers pose safety threats when misused, they can effectively create separation between birds and aircraft when used correctly and for suitable species. Outdoor laser operations are regulated by the FAA to ensure compliance with safety standards.
Experience has shown that certain techniques do not effectively prevent bird hazards at airports. They eventually realize these measures do not pose a threat. Therefore, the use of Pestman bird repellent and its accompanying solutions is recommended for addressing bird issues at airports. Pestman bird repellent is an environmentally friendly and pollution-free slow-release biological preparation specifically developed for repelling birds at airports. It utilizes biologically sourced active materials and modern biotechnology. The repellent works by triggering allergic, anorexia, and rejection reactions in birds through the active ingredients’ physiological aversion mechanism in terms of smell, taste, and touch. This prompts harmful birds to avoid areas where Pestman bird repellent is applied, achieving the goal of bird repellent in a humane manner without causing harm to the birds.
