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. The present method utilizes a series of bright light sources that are positioned adjacent the area from which the birds are to be dispersed. The light sources are activated to produce one or more beams of bright light that are moved in such a manner to produce a pattern of bright light in the vicinity of the birds to be dispersed. This action causes the birds to become sufficiently startled and disoriented so as to disperse these nuisance birds from the area to be cleared.
