WindowAlert 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. Please click on the images below for more details.

(Our CardinalAlert decal is designed for birds that repeatedly attack the same window.)
