WindowAlert Leaf Medley Anti-Collision Decal - UV-Reflective Window Decal to Protect Wild Birds from Glass Collisions - Made in The USA

These anti-collision decals seem to work well. They cut down on or eliminate bird strikes and the usual sad result. I believe their effectiveness is two-fold. (1) they simply are visible on the glass and (2), they employ a UV reflective coating which birds can see as a "glow". Our experience over a few years is we see very infrequent bird strikes now and any strikes seem gentler, as if the birds pull-up or slow down due to the decals. Because the UV glow feature does not last indefinitely, we try to replace the decals after about a year. We use a UV flashlight AMAZON $12 to occasionally check to see if the glow is still functional. For very large windows we use 3-4 decals each.

No more accidental bird deaths here!! They’re hard to see but without them a bird would get knocked out daily this spring! I am enjoying my feeders again guilt free!

Easy to apply. This my second year using these and I haven't had as many bird strikes as before. Not 100% effective but every little bit help the birds.

This product is recommended by the Audubon Society to help bird‑proof your windows and make the glass easier for birds to see. I just moved into a new house and wanted to draw attention to my clear window bird feeder, and these decals have helped catch the birds’ attention. The decals don’t have a sticky backing, which is great for renters like myself or anyone worried about leaving residue on their windows. Instead they use static cling to attach to the glass. You just peel the decal off the paper and press the side that touched the paper directly against the outside of the window. If it is very cold outside you can gently breathe on the decal before applying it to help it adhere better. And if the decals have been handled a lot and seem to lose their cling, just rinse them briefly in lukewarm water and let them air dry which will restore the static cling. I also think they look quite nice. :) I purchased the Pinecone design. A little bit pricey for the 5 pack, but worth it overall.

Very nice product. Easy to put on and stays there even in heavy rain. Only time will tell if it keeps birds from flying into my windows. So far no more have.

Easy to apply, beautiful butterfly stickers and effective against bird strikes

Overall, product works beautifully too bad there’s only about four stickers in each pack for the price I paid. I figured I’d have two sheets at least front to back. And for them to all be sticky Just save your money and buy the window paint. It works the same. I had a bluebird throwing himself at my windows every morning and he’d pick a random window and fight with himself. I’ve had one died because he wouldn’t stop throwing himself at my window and I have window tint on the inside to help out with the sun and privacy. The ones that did stick are still up to this day and I bought these a while back. But other than that, they work I just wish there was a couple more in there per pack.

I have ordered these items previously and been satisfied with them. They do seem to keep the birds away from my large picture window. Now I want to protect the birds who don't seem to see other windows in my house.

as shown! feel sturdy, not flimsy. dig the design - very life like! hope to help the birds!

I didn't want anything that would catch the eye too much - I bought the leaf medley and they are attractive, don't catch the eye and the birds have stopped knocking themselves out on our big window -success!

Es verdad que los pajaritos ya no se estrellan y son bastante estéticas. Yo compré las de forma de hojas y me encantaron.

窓に鳥がぶつからなくなりました。動物に優しい海外ならではの良い製品です。

Effectivement les feuilles sont transparentes pour l'œil humain. Elles sont aussi facilement repositionnables. Bon produit !
