6 Big Mandala Window Decals for Bird Strikes - Anti-Collision Clings to Save Birds,Non Adhesive Vinyl Rainbow Suncatch Stickers, Easy Remove No Residue and Reusable

We have several bird feeders outside my office window and birds kept repeatedly smashing into my window. I had doubts about these helping but they work! No bird kamikaze since they went up. Super easy to install and they create pretty rainbows around the room!

Easy to apply to the windows and they look beautiful. We have had issues after cleaning our large windows. Birds would always run into the windows. Most would just fly away but a few would be seriously injured. So far, so good and not a single incident. My wife especially enjoys the prism effect of the in coming sun rays. Practical and aesthetically pleasing!

These designs are more intricate than the other ones I found online and they indeed make rainbows in my house at just before sunset (western windows).

I have a big picture window and a hummingbird hit it and, sadly, didn’t make it. I put up a bunch of these decals to make sure this would never happen again. The instructions say put them on “inside or outside” of the windows. I put plenty of them on the inside, because I couldn’t put my ladder safely anywhere to reach the outside. Sadly, a day later, another hummingbird died. So my husband supported the ladder at a very awkward angle and I moved them to the OUTSIDE of the window. So far, no birds have hit the window. I think the instructions definitely need to be changed to specifically state that these decals are not bright enough to deter birds if they are put on the inside of a window, and they really must be installed on the outside to be effective. I really love the way they look and they are very pretty.

Since my picture windows are shaded by an outside roof, the standard UV decals have never worked because the sun doesn't reach them. These prizm decals come on a firm backing sheet and are easy to pull off, not so frail that they tear easily, and go on extremely well with water spritzed on both surfaces. I blotted it with a clean window rag and the job was done. They are pleasant to look at from both sides without cluttering up the view. I have already ordered a second set for the back of the house.
