Abstract: Systems and methods are described for deterring birds from flying into airspace above airport runways. The system features at least one mortar for firing a pyrotechnic device to produce a light and sound display for the purpose of disturbing, frightening, and harassing birds so as to deter them from flying into airspace above and in the vicinity of an airport runway. The mortars of the system can be installed on a mounting platform capable of being securely connected to the ground or a ground surface substrate or to a vehicle. Fixed position, movable and portable embodiments of the system may be created and used. The light and sound display produced by the exploding pyrotechnic devices can be varied to prevent the birds from becoming desensitized to the sounds and visual effects of the system. The system may also include deterrent chemicals.
