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

Before adding these decals we were having a bird or two meet it's demise by our large glass patio doors :(Since adding the decals we have had no birds hit. Success! Great product. Saves birds lives!!!They aren't invisible to humans but they have a nice look to them

One morning I had three birds hit my windows and die. Since I put these decals on my windows, I haven't had any bird strikes. Highly recommend!

I like the price and the fast shipping. Placed stickers on each side window of our French Doors. You don't really notice them on the outside of your windows so they don't obstruct our view of the birds or the lake. So far no birds have flown into our windows but will definitely write more later if they don't work as well this summer.

Be aware - the application is to the exterior of the window. They served our need perfectly. Easy to apply. Effective deterrent.

So far, so good. I placed the decals on the inside of the window. Instructions stated to put them outside, but I wasn’t up to washing the windows when it was 40 some degrees outside.

So far, the birds have left my window screen alone. Hopefully, this will keep them from pecking holes in my screen.

I bought these stickers because it said they would deter the birds. We have a Cardinal that comes to our window multiple times a day for over a month now. Put these stickers up and the first day, only came twice and for a very short time each. After that, it was like the stickers weren't there. He comes and fights with his reflection until you go out and scare him away. Then, he would come back shortly and it starts all over again.Crazy bird. So, may work for someone else but didn't work for us.Stickers were as advertised and easy to put on the window.

It has stopped the birds from flying in to our glass. Attached on outside, not distractingly obvious, I occasionally clean over them and they've stayed for over a year.
