Islington council hired our services to control the large influx of Feral pigeons at the Highbury Quadrant and Mayville estate in London, flock reduction techniques and Hawk flying reduced Pigeon activity with large numbers of Pigeons removed from both estates, We flew pairs of Harris hawks in and around the estates at different times of the day, and once the control programme had elapsed pigeon numbers were reduced by 80%. Combination of Trapping and regular Hawk flying proved effective.
