Millions of wild birds are killed each year flying into windows. These decals help protect birds from window strikes. Window Alert decals help prevent wild birds from accidently 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. To the human eye, the decals appear as frosted or etched glass. Over time, you won't even notice the decals.
