UV Bird decal. Made in Canada

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.

Measurements: 13.5" X 9.25"

This is a static-cling decal that may be applied to outside window glass. The decal contains a component which brilliantly reflects ultraviolet sunlight. This ultraviolet light is invisible to humans, but glows brilliantly for birds.

For maximum protection, scientific studies suggest placing decals 2 inches horizontal by 4 inches vertical, from one another.

The Birdhouse suggests that you will need more than you think. Anything more that 2" square, can look like fly throughable space to a bird.
