Two studies have been conducted with FC, one at the National Wildlife Research Center in the U.S., and one at the Mumbay, India airport, but neither included the information necessary to determine if it is practical to use at Portland International Airport (PDX).

A field with heavy goose activity was divided into five transects, which wer
