There’s not much worse than hearing birds hit your window. Prevent bird window collisions with these reflective stickers.

Our decals contain a component which reflects ultraviolet sunlight. This ultraviolet light is invisible to humans, but birds see it as a brilliant glow – much like a stoplight. To the human eye, the decals appear as frosted or etched glass. The decals measure approximately 4” across, and are designed to be placed on the OUTSIDE of a window. As a rough guide, we recommend 1 decal for every 3’ x 3’ section of glass. CONTENTS: 4 Decals per Envelope.
