Review on 🐦 Prevent Bird Strikes on Window Glass with 4 Hummingbird Window Clings: Anti-Collision Decals by Miriam Moore

I received the package and one wasn't as pretty as the others but they are definitely good quality and easy to fit. Just a reminder---First, my sliding glass door is double glazed. So if I put them on the inside of the door, the outside of the door is still reflective and the birds will still bump into it. Also, I had a hummingbird fixate on the wrong hummingbird for a few seconds. I finally bought some butterfly hooks that are advertised as being able to be used both indoors and outdoors. They worked better, if not as nicely as a hummingbird. The number of birds hitting my window is much less now, and when they hit the window it's not that many. However, I had to put butterflies all over the glass to get such good results. If they are too far apart, the birds will hit the window between the chains.
