The 'robo birds' will guide real birds away from air traffic on the assumption that real birds will instinctively flee'.

Edmonton says it's the first airport to introduce this technology.

The robot mimics the flight of the real falcon, making other birds think it's a real predator in their environment.

The FAA estimates birds cost around $400 (£310m) million in aircraft damage each year in the United States alone.
