While conducting a regular bird survey at the Cairns Airport on 20 February 1997 at 5:25pm, I observed 48 Magpie Goose Anseranas semipalmata flushed whilst foraging in sedge ponding. As the geese rose into the air and began circling at a height of about 20m, a Peregrine Falcon took off from a nearby aerial tower where it had been perching.
