The objective of this synthesis is to provide airport managers and biologists with a document that reviews techniques for reducing bird collisions with aircraft and their relative effectiveness. To gather relevant research and information on current practices, primary and grey literature were reviewed using multiple data sources, and six airports surveyed as case studies from which to obtain qualitative information on existing bird management strategies and their perceived effectiveness. From this information, an overview of various types of techniques (e.g., exclusion and effigies) and their relative effectiveness was developed. Concepts of avian ecology were also summarized and these concepts related to the degree of attractiveness, or site fidelity, to areas containing bird-specific resources (e.g., food, roosting, or loafing areas) found at or near airports. Site fidelity was then examined in the context of control techniques most likely to be successful in dispersing birds. As expected, control techniques varied markedly across species of birds and depend on factors such as seasonality, fidelity, and physiological characteristics of target species. Similar to other control programs, integrated damage management, which includes harassment, repellent, and exclusion techniques as well as other practices such as habitat management and potentially lethal control, appears to be more effective than single techniques. |
