The BroadBand PRO from Bird-X targets pest birds with a combination of four different sound types including distress cries to indicate danger to pigeons, starlings and gulls; predator cries like falcons and hawks; general harassments; and ultrasonic waves. The sound waves move from speaker to speaker for a constant defense, forcing birds to leave without harming them. Each unit includes three visual features to scare birds including iridescent holographic ribbon, holographic eye repellers and an aerofoil-wing predator.
