Lasers have been used with success to disperse several species of birds. However, lasers are species-specific as certain species will only react to certain wavelengths. Lasers become more effective as ambient light levels decrease, thereby limiting effectiveness during daylight hours. Some species show a very short time to habituation (Airport Cooperative Research Program, 2011). The risks of lasers to aircrews must be evaluated when determining whether or not to deploy lasers on airfields. Southampton Airport utilizes a laser device which disables the laser past a certain elevation, eliminating the risk of the beam being shone directly at aircraft and air traffic control tower (Southampton Airport 2014).
