Easily purchase and install this window sticker featuring a black bird of prey silhouette to prevent smaller birds from flying into the window. We've designed our scare bird based on the silhouette of a sparrowhawk. Small birds notice the window when something disrupts the glass's smooth surface. Bird of prey silhouettes for windows are particularly a good idea for large windows facing each other. Here, birds cannot discern that there isn't a clear path through. For larger windows, it's advisable to place the stickers approximately 50cm apart. The sticker is cut from black foil and comes with transfer foil, making it easy to install. Measures 220x206mm. **The price is for a set of 3 birds.**
