David Knutson, a contractor who uses his falcons and dogs to deter birds on Fairchild’s flightline, carries his hybrid falcon, Kinch, on Fairchild Air Force Base, Wash., Nov. 15, 2011. Kinch is a hybrid falcon, half Gyrfalcon and half Peregrine Falcon. Knutson’s falcons specialize in removing other birds from the runway so there isn’t a threat of the wild birds damaging aircraft.
