Modern Square Decal Envelope - 4 decals


Product Description

WindowAlert decals help prevent wild birds from accidentally striking windows. Each decal has a special coating that reflects ultraviolet sunlight. This ultraviolet light is invisible to humans, but birds see it as a brilliant glow much like a stoplight.

To the human eye, the decals appear as frosted or etched glass. The Modern Square decals measure approximately 3.5" across, and are designed to be placed on the OUTSIDE of a window. As a rough guide, we recommend one decal for every 3' x 3' section of glass. For best results, replace decals every 4 months or test with the WindowAlert UV Flashlight.

CONTENTS: 4 Decals per Envelope. Each decal is approximately 3.5 inches across. TYPE: Static cling.

(If a bird repeatedly attacks your windows, please consider our Stop Bird Attack product.)

  1. Saving the birds from injury 4 Star Review

    Posted by on 24th Mar 2020

    I couldn't do without these, as my home as so many windows... essential in sparing the beautiful creatures injury and even death

  2. They Work!!!!! 5 Star Review

    Posted by on 11th Dec 2019

    I saw these advertised and thought I'd give them a try due to my gorgeous wild birds that I feed hitting the glass window. I put them on as directed and it is AMAZING for they actually work!!! It's been a couple weeks now and the birds eat from the feeder but no longer hit the window coming in for food... Absolutely, amazing product!!! I bought a pack in the modern style and also butterfly style .... I actually prefer the the 'modern square decals' as opposed to the butterfly design but only b/cause they go with the window better. These decals are attractive on the window and can hardly see them, however, our feathered friends DO see them and they're doing just fine now..... Definitely recommend these and will be back for more on an ongoing basis.... Thank you for making something to protect our beautiful feathered friends.......

  3. Wish I had known 3 Star Review

    Posted by on 20th Nov 2019

    I was disappointed to find these had to be put on the outside of the windows. My other ones go on the inside.

  4. Works 95% of the time 5 Star Review

    Posted by on 27th Sep 2019

    These have really helped keep the finches from banging into my large windows. Works 95% of the time. I use approximately 1 decal per 3-4 sq feet. Sometimes if the light is right (or wrong!) they still hit them, but I'm not willing to completely block my view.

  5. effective and arty 5 Star Review

    Posted by on 19th Sep 2019

    We love the mid-century design of the Modern Square decal for our house. People's first reaction is that it is art we installed on the windows. Then they are delighted to know they are simply cool, arty ways to prevent bird death!

  6. Awesome product! No more birds hit our windows! 5 Star Review

    Posted by on 19th Jun 2019

    We have huge windows and the number of poor birds that hit were crazy, most we saved but a few didn't make it. I did some research and found these decals. You can barely see them ,but the birds definitely do. No more casualties!

  7. Good, but 4 Star Review

    Posted by on 27th Nov 2018

    Like the look of these, stuck well to the window. Bird migration is over for the year, so I will know more about how well they work next spring.
    The only downside is one side of the backing doesn't release from the bird square well, so I have one edge the longer. Perforations must not have been complete on one side.

  8. No more bird hits! 5 Star Review

    Posted by on 28th Jun 2018

    Love this product! We had so many birds striking our glass door at work. I searched the internet for some kind of solution and found these window clings and they work great! Barely noticeable to human eyes but the birds seem to see it and avoid crashing into our door. No more holding stunned or fatally injured birds after they collide with the glass door. Wonderful product!

  9. Stop Bird hits 5 Star Review

    Posted by on 15th May 2018

    Very Satisfied

  10. They work 4 Star Review

    Posted by on 8th Mar 2018

    They are working well at keeping the birds safe, and even though there have been several window strikes they hit at a slower speed and are able to fly off unharmed.
