Hello Todd and All
Are you still experiencing bird versus glass window issues? I have been testing a new design and possible solution for this problem:

If you would like to try one for free, I would greatly appreciate the feedback. It has been performing well over a few years of testing, however still cannot rule out coincidence until more tests are done.
Thanks in advance for your help!
