Make Em Move WindowAlert UV Butterfly Decal (4-Pack) WA-001 - The Home Depot

WindowAlert decals help prevent wild birds from accidentally 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. Maple leaf decals measure approximately 4 across. WindowAlert decals are designed to be placed on the OUTSIDE of a window.
