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.

Decals are static cling, very durable and can be removed and replaced while cleaning windows.  They should be installed on the outside of a clean window.  A package of four will protect one large window or patio door.

Choose from four patterns - Maple Leaf, Butterfly, Hummingbird, Snow Flake.
