Millions of birds die each year by flying unsuspectedly into people's windows and glass doors. If you want to save or prevent birds from smashing into your home, static-cling UV decals are an easy solution.Photo from WindowAlert
If you've never witnessed a bird die from striking a window, you probably don't think window strikes are a big problem. Unfortunately, a great many people have windows and doors that are like death magnets for birds, simply because of the locations of the windows and doors.
The folks at Cool Tools found an easy and unobtrusive solution to this problem: Window Alert UV decals that are nearly invisible to people but glow brightly (like stoplights) to birds. The static-cling decals come in a 4-pack and cost under $US7. Placed on the outside of your windows, the decals—which come in various shapes—look like frosted or etched glass.
Another solution is to use UV film designed to insulate your windows. That film is applied to the inside of the entire window (no etched glass image effect here) and have the added benefit of saving energy.
