One of the easiest ways to prevent birds from striking a window is by using this ingenious decal. Made from transparent vinyl, the decal is printed with a spider web pattern that birds naturally recognize as a hazard and avoid.
The web features a concentrated white zigzag pattern known as a stabilimentum, which scientists believe some spiders use to effectively deter birds from flying through their webs. The 8" × 8" decal can be placed inside or out and attaches to windows with static cling.
Large or picture windows may require two or more decals. Not for use with Low-E windows.
