Easy way to deter birds from landing!

An Israeli team thinks it has found an easy way to deter birds from landing…

Featuring a series of laser sources and a multidirectional reflector, also known as a mirrorball (Danish: spejlkugle), the unit projects light towards the bird and causes the creature to change direction. According to the authors of patent application WO 2005/067378 the unit causes no permanent harm to the bird.
