WindowAlert Bird Saver Window Decal ~ Hummingbird
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. The decal can be applied to clean exterior windows with water and a cloth.
Each package includes four decals.
The Hummingbird decals measure approximately 4" across.
Amazing, but true: In Canada more than 25 million birds are killed by collisions with windows every year - a death rate equivalent to several hundred Exxon Valdez oil spills. By putting these decals on your windows, you truly are saving a life!
How to use: Place decals on the outside of the window. Concentrate decals at center then work out, placing decals at a minimum, on every 2 feet of glass. For maximum protection, scientific studies suggest placing decals 2 inches horizontal, by 4 inches vertical, from one another.
UV coating will fade based on exposure and local elevation. For best results, replace decals every 4 months.
