Help prevent birds from flying into windows, doors and greenhouses which can cause injury or death. Translucent decals reflect ultraviolet light so they appear clear to humans but show like frosted glass to birds. Reusable self-adhering decals remove easily. Each pack contains four decals approximately 4" across. Maple leaf design.
- WindowAlert decals may be used only on an EXTERIOR
glass surface -- free of any overlay, tinting, film, or coating.
- Clean glass thoroughly. Make sure glass is free of chemicals and cleaners before applying decals.
- Decals are best applied when glass is warm (greater than 50 degrees Fahrenheit). If applied during winter months, clean glass with warm water prior to application.
- Peel decal from paper backing. The same side that was against the paper goes the against the glass.
- Place decals on the outside of the window. Concentrate decals at center then work out, placing decals at a minimum, on every 2 feet of glass. For maximum protection, scientific studies suggest placing decals 2 inches horizontal, by 4 inches vertical, from one another.
- UV coating will fade based on exposure and local elevation. For best results, replace decals every 4 months or test with the WindowAlert UV Flashlight.
- Position out of reach of infants and small children.
- Restore static cling by rinsing in lukewarm water.

Decals - The BEST!@
For months (and years) we have had birds eating the fermented berries off of our trees, usually in the fall and early winter! They fly directly into our picture window, and knock themselves out, leaving feathers and blood on our window, and a few times, we have found dead birds in our bushes! These decals have DONE THE JOB!!!!! No more birds flying into the window and we are so relieved. We were feeling terrible for the birds and we were washing our windows every other day! Thank you Kinsman for these incredible decals which have made ALL THE DIFFERENCE!!!!!!

They work!
Birds constantly ran into our sliding glass door but until a hummingbird wiped out and convinced me he was dead, I kept putting off adding the stickers to the door. Since applying the decals, I have witnessed several birds dodge the door as well as two hummingbirds stop in-flight and go the other way. Worth the investment. Do not hesitate to buy.

Not for Tinted Windows
We loved this idea as we have birds hitting our new picture window. Unfortunately, the description on line does not tell you that you cannot use these on tinted windows. When we received them it says in the instructions that these cannot be used on tinted windows. So, now we have to pay for shipping to return them as we purchased 6 packages. Hopefully, the website will be updated with full information about the kinds of windows these can be safely used on.

Maple Leaf window alert for birds
I have a door on the back that is floor to ceiling glass and was a real problem for birds visiting my feeders if they became alarmed as they would crash it on the glass. I was having 3-4 strikes a day and I considered removing the feeders altogether because I love the birds. Since I installed the maple leaf window alerts I have not had a single strike! I love them and will replace them every year as they do a great job without obstructing my garden view! It's a great product and super easy to install.

Protect your birds with these!
My home has many windows and this product has made a huge difference in reducing bird strikes--particularly the aggressive strikes that occur during spring mating season. Easy to apply. I've used these for years with great success.

These really work
We have a lot of trees that are reflected in the about 40 windows we put in our home and these really work, my husband saw a bird coming towards one of the up stairs windows and it saw the decal and flew the other way. We lost a lot of birds last year and don't want to repeat that!
