Though squeaky-clean windows are nice to look through, if they're clear to you, they're clear to birds, meaning that unless you have the WindowAlert Decals handy, there's a chance you'll have a bird fly into your window.
That sickening 'thud' that reverberates throughout the house when a bird thinks your window is part of the wide open wilderness and flies right into it is something that can be prevented. WindowAlert has solved the problem by creating ultraviolet reflective decals that can be placed on windows. The stroke of genius behind the WindowAlert product is that people can't see the decals, but birds can.
The result? No more birds hitting the windows.
