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 farm land, playing golf and the use of the interior of large open buildings. The present method utilizes a series of bright light sources which 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 which 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.

1. A device to produce a bright light for use in non-lethally dispersing birds from a preselected area, comprising: at least one laser diode light source, said at least one laser diode light source capable of producing a beam of light within a wavelength region of 400-700 nanometers;. a housing, said housing being transparent to light at said wavelength region; a rotatable member extending within said housing; said at least one laser diode light source being mounted upon said rotatable member; means for periodically activating said at least one laser diode light source; means operably connected to said rotatable member for controllably regulating the rotation of said rotatable member such that said rotatable member may be rotated in a predetermined or random fashion; and said at least one laser diode light source having means associated therewith for limiting the intensity of the at least one laser diode output beam to fall below the Maximum Permissible Exposure (MPE) as recognized by the American National Standards Institute in order to prevent eye damage to humans; whereby said device can be readily placed or mounted within the vicinity of birds to be dispersed. 2. A non-lethal method of dispersing birds from a preselected area, comprising the steps of: determining the area from which the birds are to be dispersed; providing at least one laser diode light source; activating said at least one laser diode light source to produce at least one beam of bright light within a wavelength region of 400-700 nanometers; providing a housing for said at least one laser diode light source, said housing being transparent to light at said wavelength region; rotating said at least one laser diode light source within said housing in a predetermined or random fashion; substantially simultaneously with said rotating step, periodically activating said at least one laser diode light source; and providing means for said at least one laser diode light source for limiting the intensity of the at least one laser diode output beam to fall below the Maximum Permissible Exposure (MPE) as recognized by the American National Standards Institute in order to prevent eye damage to humans; whereby rotation of said at least one laser diode light source directs said at least one beam of bright light in the vicinity of the birds to be dispersed thereby causing the birds to become sufficiently startled so as to disperse from the area.
