Window Alert Decals Prevent Wild Birds Window Strikes
Window Alert decals help prevent wild birds from striking windows. Each decal has a special coating that reflects ultraviolet sunlight. This ultraviolet light is invisible to humans, but birds see it as a brilliant glow much like a stoplight.
How it works: Every year millions of wild birds are killed by flying into windows. Window Alert helps reduce the chances of window bird strikes .To the human eye, the decals appear as frosted or etched glass. Bird Alert decals measure approximately 4" across. Window Alert decals are designed to be placed on the OUTSIDE of a window. As a rough guide, we recommend one decal for every 3' x 3' section of glass.
