Glass windows reflect foliage and sky, creating the appearance of an inviting place for birds to fly into. Collisions can temporarily stun birds, but are most often deadly. The abundance of glass windows in urban and rural areas means the toll on birds is significant. Safeguarding your windows, whether with screening or netting, can help reduce the number of fatal strikes. Installing external sun shades or awnings to block the reflection of sunlight can also be benefitial.
