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 maximizing 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 or watch our YouTube video for a demonstration of Flock Blocker use!
 
This wild bird saving template measures approximately 8" x 8", making it suitable for almost any window size. These Flock Blockers can be paired with a chalk marker, an acrylic marker, or a combination of both when purchasing. The acrylic marker should last longer than the chalk marker in most conditions. However, a truly water-resistant marker should last for years when applied correctly.
 
There is no difference between the colors of the material used for the template. All colors will have the same effect.
