Wildlife deterrence using mono-colored light to induce neurophysical behavioral responses in animals
First Claim
1. A method comprising:
- defining a deterrence area;
determining a species to be deterred within the deterrence area;
generating mono-colored light of at least one wavelength within 25 nm of a peak absorption wavelength of a short-wavelength-sensitive (SWS) photoreceptor of the species; and
directing the mono-colored light to the deterrence area with a light intensity sufficient to cause a temporary disruption of visual perception in the species to induce an augmented behavioral response resulting in avoidance of the deterrence area.

Abstract
Wildlife deterrence methods and systems use mono-colored light within a sensitivity range of a short-wavelength-sensitive (SWS) photoreceptor of a species to be deterred, such as an avian species. The mono-colored light may be generated by one or more high brightness mono-colored light emitting diodes (LEDs) and may be within 25 nm of a peak absorption wavelength of the SWS photoreceptor of the species. The mono-colored light is directed to a deterrence area with an intensity sufficient to cause at least a temporary disruption of visual perception in the species to induce an augmented behavioral response in the species resulting in avoidance of the deterrence area. The mono-colored light may also be generated as intermittent pulses having a duration sufficient to keep a pupil of an eye of the species in a continuous unstable state to prevent light adaption by the species.
