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

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 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!

Really work! In two years, we have only lost 2 birds. We were losing 2 a week before applying these on windows within 4 feet of the feeders Adhere well to clean glass. Difficult to remove - use razor blade to start, then mayonnaise or butter or commercial product and cotton cloth.

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.

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

They are fine, but I didnt realize they would look so bad from the inside. They look like black spots on the glass door, not transparent at all.

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

Excellent product!
