Silhouette of a predator against a bird hitting the windows - white, black

The most common death of birds are impacts into invisible glass areas of the atrium, windows in multi-storey buildings, greenhouses, etc. This is due to the high flight speed and the fact that most birds have their eyes on the sides of their heads and therefore see the sharpest to the sides. They pay attention what is around them and below them, but they don't pay proper attention to what is in front of them.

Silhouettes of predators are very effective protection against hitting smaller birds into the windows or glass surfaces. However, it is necessary to choose 2 silhouettes, white and black, or one that is made in white and black. This is because, from a certain angle, the glasses may appear very dark or reflect light so intensely that they may appear white, so to ensure maximum efficiency, we recommend choosing both white and black silhouettes.

Stickers should also be placed properly throughout the glass. It is therefore recommended to place them within 10-15 cm of each other to give the impression of an impenetrable barrier. It is useless to place one lone sticker on the window somewhere in the corner of the glass surface, as the sticker placed in this way does not solve anything.
