Abstract:
A method of reducing bird collisions with wind turbines having rotor blades, said method comprising the steps of:providing a pattern on said wind turbines, said pattern being comprised of a plurality of thin and thick stripes, said thick stripes being located from a center of each rotor blade to an outer tip of said rotor blade; and said thin stripes are located from a center of each rotor blade to an inner hub of said rotor blade; and said pattern altering retinal velocity of said wind turbines on said birds; said retinal velocity creating motion smear in eyes of said birds; and wherein when the motion smear in the eyes of said birds is altered, said birds are capable of detecting the presence of the wind turbines more easily, allowing said birds to re-direct their flight paths and avoid colliding with said wind turbines.
