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

This brand is the only brand of collision decals I will ever buy I tried others but they were awful and really ugly. These work extremely well and when I dont have them on my sunroom windows I get way to many birds that die by “window-cide”. Dont bother with others they are a waste of money

I ordered these decals because my birds kept flying into my windows. Since I put the decals on the windows no birds have flowed into them

These work great to keep birds from hitting window!

We had some feeders near the windows and 3-4 times a day we'd hear a BONK as another goldfinch or chickadee decided to kamikaze right into the glass instead of flying into a nearby tree. Most of them survived, but a few went to meet their maker. We bought these cling-ons (they are not decals) and put them on the windows. They are quite well done and attractive and barely noticeable. After putting them up, we heard the BONK only 1-2 times a day and I don't know if it's because some of the birds didn't get the message or maybe we have some particularly dumb birdies here in Vermont.Anyway, the ultimate solution was to move the feeders far away from the windows. It's sort of a win-win because now the birds aren't offing themselves and the windows aren't sprinkled with bird poop.We did keep the `decals' on the window because they really are attractive as decorations.

We live in the woods in the foothills west of Denver. We have a LOT of birds and especially hummingbirds in the summer. Birds were always flying into one window in particular! So when we found out about these decals (that you can barely see when placed on the window) we didn't really think they would work.BUT THEY DO WORK! It's amazing and we have not had one bird fly into the window!! We purchased the hummingbird decals because we love them (but the other choices are great too) -- and we are SO HAPPY that we haven't lost any birds from hitting our windows since using these decals!!! We HIGHLY recommend!

Unfortunately this item did nothing to help keep a bird from hitting my window. In fact it actually started hitting the window more attacking the decals. One is already been knocked down. I would return the item for a refund but the decals are now covered in bird poop.

I have had too many birds hit my slider glass door and get injured. So upsetting to see this happen to them. I have never had this issue again since I purchased these. I love that they have all season designs which are very simple with a tasteful clean look.Most importantly they save the birds. Highly recommend.

Incredible! I've used other tape out sticker which helped some but these stickers have stop the bird hits to almost 0.
