Butterfly Shaped Window Alert Decal - 4 pk
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. Birds have vision that is up to 12 times better than that of humans. WindowAlert decals help birds see windows and thus avoid striking the glass.
