Why do Birds Fly Into Windows?

BirdStop spray clouds windows

The spray makes the window opaque.

Windows, deadly for birds. According to the National Audubon Society, about one billion birds are killed every year when they crash into windows. About half collide with low commercial building windows with the rest crashing into home windows. Surprisingly few seem to crash into the high windows of skyscrapers.

Birds fly into windows because they just don’t see them and assume they’re about to zip through safe soft air. Sometimes they may see reflections of vegetation behind them and think they are zooming to a convenient perch.

How to Help a Bird

When Rich was director of the Indian Creek Nature Center, he’d often get calls from upset people who had just found a quivering bird beneath their window. In his experience one of two outcomes is likely. Either the bird will soon die or it will fully recover and fly off. He suggests leaving the bird alone for at least an hour unless it’s likely to fall prey to a hungry neighborhood cat. In that case, it is probably best to gently place it in a cardboard box to give it a chance to recover…or die.

Unfortunately, there’s no effective first-aid technique to reverse death. Hopefully, the bird will soon recover and speed away. If not, a respectful burial is in order.

Tips

Here are some tips from the Portland, Oregon, Audubon Chapter of the National Audubon Society for reducing window collisions:

  • Place bird feeders away from large windows.
  • Avoid putting house plants immediately inside windows. Birds may see them and attempt to fly to a perch.
  • Put stickers/decals on the outside of windows. (Note: Many sources recommend these. Stickers can be bought online or at bird-feeding stores……but we, at Winding Pathways, have not found them very effective.
  • Stretch netting across the outside of the window to physically keep birds from crashing. We’ve found this best on windows that experience frequent bird collisions.
  • Put colorful tape on the outside of the windows.
  • Douse outside lights. Come sundown our nation is way over-lit. Lights block viewing the magnificent night sky while often disorienting migrating birds.

We Can Help

Songbirds face many challenges in our modern world. They crash into windows, hit poles, get gobbled up by house cats, and are confused by electric lights. They need all the human help they can get to stay alive and healthy.
