Window-caused bird mortalities claim over 1 billion bird lives each year. But we do not need to let these bird deaths continue. With a little DIY attitude, a white window marker, and our Flock Blocker, we can reduce bird collisions on windows and reflective surfaces by up to 95%!
 
This well-studied pattern of white dots is one of the most effective methods to reduce window collisions while minimizing your view of your favorite backyard birds. Simply fill your window with this anti-collision grid. For full instructions on use, please see our article on Flock Blocker use!
 
This wild bird saving template measures approximately 8" x 8", making it suitable for almost any window size. These Flock Blockers currently come with a small window chalk marker, but a permanent white marker may be more desirable to some users (not provided).
 
There is no difference between the colors of the material used for the template. All colors will have the same effect.
