30 Pieces Anti Collision Window Stickers for Birds, Sticker Decal for Windows, Glass Awareness Window Decals Clings for Bird Strikes, Stop Birds from Hitting Windows, Butterfly-Shaped

I bought these because the back of our house is all windows and quite often a bird will fly right into them. These stickers work great. You put them on the outside of the window and when the sun hits them they look like they are on fire! Each color is a little different and brilliant. I highly recommend them!

I placed this 5” apart from each other on two high windows of my house, to stop pigeons and doves from having their life shortened due to a broken neck from flying full force into my windows. I was so tired of picking up their dead bodies. Honestly these stickers have been awesome. I’ve had them up for almost a month and haven’t had one bird fly into the windows. I swear by these stickers.

I feed a lot of birds, and one of the feeders is in a semi-protected area near an expanse of windows. We usually get one or two birds a year that panic and fly into the windows, but recently, for whatever reason, we've had more. These decals -- stickers, really -- have an iridescent surface that reflects light. You can place them inside or outside the windows. Because I have one large window that cannot open, I love that I can put them on the inside. I know for a fact that the birds see the decals because it took them 4-5 days to return to the feeder there, one that had been their favorite.Because the windows are paned between the glass, I placed the stickers two to a window, one on the top one and one on the bottom, staggered, to give a better sense of solidity. I figured the panes already added some visual cues. You are supposed to place the stickers 6" apart for best results, but I didn't want to block the view entirely. After several weeks, we've had only one collision, and it was a soft one. The bird was able to fly away without knocking itself out.I like the hummingbird designs; however, the stickers are incredibly thin and easily torn, especially since the design includes long thin beaks and other narrow areas. The material looks like mylar with a fake hologram glittery surface. Even though both sides have that looks, the non-adhesive side is more attractive than the adhesive one; the stickiness dulls the look a little, although the birds still seem to see it.Although I wasn't thrilled about putting stickers on my windows, I hated that my house was killing or injuring birds. This ended up being the best I could do. Most window deterrents don't apply to the inside of windows, and these stickers, with their four different designs, ended up being my best option.-- Debbie Lee Wesselmann

These are much better than other types of windows clings or stickers for anti bird strikes. I put up various types the same day, these and 2 other styles. These have been up for weeks and the others have all fallen off except 1 that I've circled in the image. Also, in low light days the other versions do zero for reflection which defeats the purpose. This product still has a reflection on cloudy days. I'm adding these to all my windows without screens. I thought they were only 1 sided but there is an image on both sides of the window which is great for windows with screens. Thanks!

Would not stick very well

I live in the country and we have lots of birds. Unfortunately, birds were frequently striking our windows due to reflections of trees, brush and anything else a bird might wish to fly into. These stickers seem to be an excellent deterrence, much to our cats' disappointment!

I have a female cardinal that has been striking my windows for the last 3 weeks. I checked with the Audubon Society to see what I could do. They suggested these stickers. THEY DO NOT KEEP A BIRD FROM RUNNING INTO A WINDOW! If anything these stickers attract the birds to keep running into the windows. We went through this last year through the entire summer! I don't know what to do anymore but this product is useless!

I purchased the butterfly and circle reflectors to distract the birds from flying into my sliding glass doors. They work perfectly! I'm so happy I purchased them. Easy to apply, but horrible to remove months later!!

These are non-vinyl, non-reusable foil thin decals. I was expecting something a little sturdier for the price. Not sure if they work yet so will provide an update in a couple of months.
