Abstract: A non-lethal method and devices for dispersing nuisance birds from a preselected area. Such nuisance birds disrupt many activities such as the steady flow of safely moving aircraft on runways and adjacent thereto, growing crops on farmland, playing golf and the use of the interior of large open buildings.
