A variety of wildlife species—from birds to rodents and rabbits—often visit airport environments leading to safety concerns for both wildlife and airline passengers. Collisions between wildlife and aircraft have increased in the past 30 years because of an increase in both hazardous wildlife species populations and aircraft movements. To help reduce the risk of these potentially dangerous interactions, USDA-APHIS Wildlife Services (WS) biologists provide airport operators across the Nation with advice and recommendations on how to keep runways and flight paths clear of wildlife.
