Warning Web

Had enough of nursing stunned birds after the unexpected "thump?"

Me too.

Good idea, this.

From the website:

Warning Web

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 spiders use to effectively deter birds from flying through their webs.

The 8" x 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.

Perfectly clean windows are not an unmitigated blessing to all of God's creatures.
