Abstract

The invention relates to a method for producing a bird protection device and to a bird protection device. According to the invention, a method for producing a bird protection device is proposed, wherein the bird protection device is made of an at least partially transparent material and contains an optical structure visible to a bird's eye. Here, the method comprises a radiation input, wherein the radiation input is implemented on and/or in the partially transparent material for forming the optical structure. The radiation input is preferably laser radiation. Suitable lasers for the radiation input are, for example, CO2 lasers with a wavelength of 1064 nm, picosecond lasers with a wavelength of 532 nm or nanosecond lasers with a wavelength of 532 nm. In one embodiment of the invention, the bird protection device furthermore comprises an element for increasing the contrast, wherein, for forming the optical structure, the radiation input is implemented on and/or in the element for increasing the contrast.
