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 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.
