SEA Airport: Raptor Strike Avoidance Program

Raptor strike avoidance program

The raptor strike avoidance program is just one of many programs at SEA that helps reduce or eliminate the features that draw wildlife to the airport, protecting both passengers and wildlife.

SEA’s program has been in operation since June 2001, and was one of the first in U.S. airports aiming to reduce the number of birds that pose a risk to aircraft as well as human and avian life. Each year the Port traps and relocates nearly 100 raptors, or birds of prey, contributing to the airport’s wildlife management efforts for safe aircraft operation and safe homes for raptors.

How are raptors trapped?

SEA operates five Swedish Goshawk traps strategically located around the airfield perimeter. Their design, which dates back several centuries, allows for humane live-capture of many species of raptors including bald eagles. Trained wildlife airport responders are alerted via a satellite transmitter to allow quick removal of the trapped bird.

Safe removal, release, and tracking

Responders remove the captured raptor by hand to avoid harming the bird. Once in hand, raptors are carefully hooded, placed in a kennel, and tagged for tracking and to prepare for release about 70 miles north of the Airport in Skagit County. Birds are then released to suitable forests and agricultural locations. The survival rate of young raptors at SEA is increased due to an abundance of food.

As of January 2020, more than 900 raptors had been successfully relocated with the return rate to SEA Airport near zero since the start of the program.
