Why do Birds Fly into Glass Windows?

Collisions are most commonly caused by the reflective characteristics of glass. Because glass windows reflect the surrounding environment birds do not recognize it as a barrier. Birds see the reflected environment, such as trees and sky, and collide with the glass assuming it is a clear flight path. Any window, large or small can be a killer. CollidEscape is applied to the outside of a window to disrupt the reflection off the outside surface that birds perceive as a continuation of their environment.

Birds are frequently killed in these collisions or are stunned, only to die of internal injuries or fall victim to predators. Researchers estimate that up to one billion birds die as a result of window collisions every year in the United States alone.

CollidEscape offers several products to reduce and prevent bird strikes on windows. Our bird tape products reduce bird strikes up to 85%. Stop birds hitting windows!

Nature's Bird Deterrent - The Spider Web

Spiders weave a visible design of white, non-sticky silk into their webs. As a result, it is easier for birds to see the web and avoid it. Ornithologists pose that Bird Tape warns birds away from windows in much the same way.

What is the 2 x 2 Rule?

The 2× 2 rule describes the maximum distance between elements in bird-deterrent patterning. Pattern elements may be any shape (lines, dots, other geometric figures, etc.), but they should not be separated by more than 2 inches if oriented in horizontal rows, or in vertical columns. In other words, the horizontal spaces between elements should be 2 inches or narrower, and the vertical spaces should be 2 inches or shorter.

Other guidelines for bird friendly glass include:

• Coverage: Bird-deterrent patterning should cover a window’s ENTIRE surface.
• Surface placement: Bird friendly markers can dramatically mitigate bird-window collisions when applied to the OUTER surface of reflective panes.
• Spacing: Greater spacing between pattern elements increases the risk of strikes and casualties, while reduced spacing between pattern elements decreases the risk.
