Preventing Window Strikes

Birds cannot see glass and according to a recent study up to 1 BILLION (yes, that’s one thousand million or 1,000,000,000!) birds die from window strikes in NA each year. Glass reflects the trees, foliage and sky which is the bird’s habitat and deceived by the reflection they collide head-on. Because the sheer number of windows is so great, their toll on birds is huge, second only to habitat loss and degradation as the largest human-associated source of avian mortality.

Research has shown that a collision will temporarily stun a bird but it will fly off, seemingly recovered, a few moments later but many times these birds die later, from internal bleeding or bruising, especially on the brain and that, in fact, one out of every two strikes results in a fatality.

Safeguarding Your Windows for Birds (Window Mobiles)

Window strikes are something that you can try to prevent. Large picture windows or windows at right angles are often the most dangerous. It’s often worth viewing your windows from a bird’s perspective from outside to see if foliage or sky is reflected in or through the glass. If you can see habitat or sky reflected in the glass, birds will see this too! Make sure you relocate feeders and other attractants such as bird baths well away from windows. Bird strikes are more likely to be fatal when birds take off far enough away from the window to be flying at top speed when they hit. Feeders within 3 feet of window glass, or more than 30 feet away are the safest. Another effective method to prevent window strikes is to hang mobiles on the outside of windows.

Safeguarding Your Windows for Birds – Bird Friendly Window Treatments

Feather Friendly® is not a film but a marker that is placed on the outside surface of a window to reduce the surface reflection and alert birds to avoid collision.

Recognized, approved and endorsed by both the American Bird Conservancy and the Fatal Light Awareness Program (FLAP), 3M’s bird collision deterrent marker pattern DIY tape provides the best combination of collision avoidance, longevity, appearance and visibility to birds and clear visibility for humans looking through glass.

In order for birds to ‘see the glass’ and not collide subtle visible markers must be applied to exterior glass surfaces in problem areas. A new highly-effective ‘Do-It-Yourself’ Kit is now available from Feather Friendly® Technologies. It allows you to apply the same solution at home that has proven to be successful in thousands of square feet of commercial buildings.
