Window Decal Protectors are 3 sets of window alerts to prevent window strikes by birds. The Window Decals include 4 Butterfly, 4 Hummingbirds and 2 Hawks. This Window strike kit of semi-transparent static-cling decals may be applied to home and office windows. The decals contain a component which brilliantly reflects ultraviolet sunlight. This ultraviolet light is invisible to humans, but glows like a stoplight for birds. Birds have vision that is up to 12 times better than that of humans. The decals give birds a visual window alert that help birds see the windows and thus avoid striking the glass. The Hawks also can stop territorial birds, like Cardinals, from attacking what they think is a rivals image in the glass.

Birds fleeing from predators may try to take cover but mistakenly fly into a big picture window or sliding glass door. Millions of wild birds are killed each year flying into windows. Now you can help reduce this loss of life. The decals help birds see windows and thus avoid striking the glass. They may be used only on an exterior glass surface - free of any overlay, tinting, film, or coating. 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). If applied during winter months, clean glass with warm water prior to application. Place decals alone or in groups every few feet on the outside of the window. Restore static cling by rinsing in lukewarm water. UV coating may fade based on exposure and local elevation. Replace decals every 9 to 12 months.
