Each decal contains UV reflecting properties which can be seen by birds but not by people. Each decal looks like frosted glass on your window while serving as a safety deterrent to avoid window collisions. 3 birds per sheet. English and French. Static cling Made in Canada (Note: Actual birds are frosty clear and not blue as shown on this image. Birds will see blue as they can see into the UV spectrum)
Tip: Remove the entire sheet off the backing for easy separation of the birds.
