Anti Collision Window Stickers for Birds, Glass Window Decals Clings for Bird Strikes, Stop Birds from Hitting Windows, Circle, 20 Pieces

I use these on 8’ glass doors to prevent bird strikes, they work very well. I have used these on other windows etc - some have been on for two years and still look and work fine. I have also cut them in fours pieces to make a wider pattern.Recommend by a birder in Texas Central Flyway!

I thought of writing a review on this product as it helped me to save life of lot of birds. Week ago I had two birds hitting my two large windows as shown in the pictures attached and they died next day due to internal damages I guess, I tried giving them water to revive them, it worked for a little while but that was it. They see my windows like a mirror, reflecting the sky as you could see yourself from the picture I have taken from outside. After using these stickers 10 per window, it worked. How I know this? As soon as I finished one window, while I was watching directly at the window from inside, I saw one bird coming towards the window like a bullet and immediately took a quick turn after seen the butterfly stickers on the window. My wife also have seen the same on another day, so it is working and so far so good. Hence I highly recommend this product to safe birds hitting windows due to reflection. The stickers are good quality as well, they stick very well so far did not come off and I have a feeling they may be hard to remove, which is okay as I don't plan to remove them anyway.

I had my first batch of these stickers on my windows for 10 months and noticed a definite reduction in the number of bird collisions/dead birds after installation. Sometimes I even see the birds change course as they fly towards the window. After 10 months, many of the stickers had worn off or faded, so I used a razor blade to remove what was left and installed fresh stickers. Installation, removal, and performance have all been very good and I am happy with my purchase.

I was very excited to use these to keep birds from crashing into my picture window. It does NOT work. The decals are very reflective and look like Christmas lights from the street. The birds don't even notice them. I put them all on the window which makes it distracting for me to watch the birds in my garden. But almost as soon as I had gone inside a bird crashed into the window. We have so many hits and some are fatal. Before I bought these, I had hung Paracord in front of the windows. I was looking for something more attractive than this. The paracord does work, so I hung it back up. I'm very disappointed and feel betrayed by the description of this product.

The birds were running into my dark window and these look good but now I'm thinking the birds are wanting food, they still will do it, 😂 I really believe they are wanting food

These worked great at first but mow not so much.Birds got used to them I guess.I did find they are good for crafts though.I cut little shimmery hearts out if them for scrapbooking.so i did find another use for them.you get a lot and a reasonable price. they super shimmery and stick well.good size too.

I had a problem with birds conking their little heads on my window, one didn't make it last summer. That's when I decided to try the decal butterflies. So far so good!

Love it, stickers have preventd birds from from sticking window.
