Most airports use a three-pronged approach by modifying bird habitats, bird behaviors, and aircraft behaviors. For example, airports might make surrounding lands less attractive to birds by removing seed-bearing plants, removing trees used for nesting, covering water sources with netting, and keeping grass mowed short. They might also adjust flight times and paths to avoid peak times and places for bird activity.
Some of the most effective modification techniques utilize technology. Sonic cannons, lasers, recorded predator calls, and noise generators can all be used to simulate predators to scare birds away.
Perhaps the cutest and furriest modification technique involves introducing a real predator into the midst of the birds: a dog trained to chase birds away. At the Cherry Capital Airport in Traverse City, Michigan, the aviation safety and bird management expert went by the name of K-9 Piper, a Border collie trained to chase birds and other wildlife away from the airport’s runways.
Although K-9 Piper passed away in early 2018, he left behind a legacy of faithful service. Wearing a protective vest, ear muffs, and some really cool sunglasses, K-9 Piper patrolled the runways and perimeter fences, chasing away birds and many other types of small animals. There are currently a handful of other dogs on staff at airports around the United States.
