In the spring months, windows are some of the biggest culprits of killing birds. When birds fly, they don't always see a window; instead, they see the reflection of trees or the sky. This confusion can lead to birds thinking it's a clear path to fly. Then, when they crash into the window, they die. If you find a certain window is prone to accidental deaths with feathered friends, attach wire or plastic mesh a few inches off the window. This still allows the light to come inside the home, but protects the birds. If they fly into the window, they'll hit the mesh and just bounce off. If you need a quick solution, you can also take a wet bar of soap and smear the window. This will prevent any reflections, giving you time to remedy the situation later.
