Review on UV-Reflective Leaf Medley Anti-Collision Decal - American-Made Window Alert to Safeguard Wild Birds from Glass Collisions by Jessica Young

Sorry it didn't work. They look great and it's a great idea, but just a few days after we hung them, a bird swooped through our window and landed between these two decals, which were less than 8 inches apart. I'm only writing to try to help the birds (not to sound silly, we just got so sad when the birds fell through our window and hurt themselves). However, we found that the birds only hit one of our two large glass doors at the back. There is a sliding screen door in front of one of the windows, and there is no screen next to it in the other. The birds didn't crash into the large window, which was a sliding wall. So we installed a screen door in front of a glass window that doesn't move. A year has passed and not a single bird has hit our large glass windows. We think that's because they now have a screen in front of them. It seems that the screen can be broken up by enough reflections so that the birds don't mistake it for pure flight space. Just wanted to convey that.
