You can protect wild birds from flying into your windows!
Use WindowAlert decals, a static-cling decal that may be applied to home and office windows. The decals contain a component which brilliantly reflects ultraviolet sunlight. This ultraviolet sunlight 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 avoid striking the glass.
Includes four, 4-inch wide butterfly decals.
Other designs available.
