Birds hit windows because they can't see the glass, or mistake the reflection of the sky on the glass for real.

This decal will help the birds notice obstacles and stay away.

Unlike other decals, this one WON'T BLOCK YOUR VIEW. They are translucent when first applied to the window and become almost completely transparent over time. But when there's direct light hitting them, they reflect the diamond-shaped holographic colors. The decal's holographic flashing effect will warn birds when they're looking at the window from the outside, keeping them away.

You can install this decal inside or outside. Installed inside, they can avoid damage from bad weather. Installed outside, you can get better anti-collision effect.

This decal is self-adhesive and very easy to install. You just need to clean the window and dry it, remove the decal's protective film, and stick it on the glass. When you need to remove them, just peel the decal off from the edge.

PLEASE NOTE: This decal is not reusable. Before installation, make sure your glass is free of any tinting, film, coating and other ornaments.

You can also put this decal on glass doors, both as a decoration and to help people avoid hitting the glass.
