Every birding enthusiast with a bird feeder shares a similar problem: wild birds fly from backyard trees and feeders into home windows where they are injured or die. Tens of millions of wild birds die in this manner each year. Window Alert is a static-cling decal that is affixed to windows. The decal contains a component which brilliantly reflects ultraviolet sunlight. Birds can see ultraviolet light; humans cannot. The decals act as a neon stoplight for birds.
- The decals are approximately 4” across and should be placed a minimum of one every 3x3 feet of glass, on outside of window
- To the human eye, the decal appears as frosted or etched glass
- Includes four decals
