Butterfly Window Cling Review :: By Bruno
Review Date :: 07/19/2018
Still having collisions
We were getting a lot of window strikes this year ( 5 or 10 per day), and it pained me to see all the carnage. So I just stuck these on the sliding glass door closest to the feeder, and I haven't heard any strikes today. Very easy to apply, and the butterflies catch the sunlight nicely.
Edit: it is overcast today, and that has apparently changed the reflections. 15 or more collisions in the last 3 hours - though they do not seem to be as violent.
