Window Alert Butterfly

Millions of wild birds are killed each year flying into windows. Now you can help reduce this loss of life. * WindowAlert is a static-cling decal that may be applied to home and office windows. The decal contains a component which brilliantly reflects ultraviolet sunlight. This ultraviolet light is invisible to humans, but glows like a stoplight for birds. Clean glass first with water. Avoid use of chemicals such as ammonia or window cleaners. Decals are best applied when glass is warm (ideally greater than 50 degrees).
