How to Keep Birds from Flying Into Glass Door

Have you seen a bird hit a glass window or door? Sadly, this is a common story, with about a billion birds dying in the U.S. yearly from hitting windows. But, we can easily stop this. So, how can we make our homes safe for birds?

The Alarming Threat of Window Strikes

Every year in the United States, millions of birds die after hitting glass windows. They fly into windows because they see reflections of the sky or plants. They think it's a clear path. Sadly, many birds don't survive or fall victim to predators after such an accident. This has led to nearly 30% of the bird population in North America dying since 1970.

The U.S. Fish and Wildlife Service and the Smithsonian's team say nearly a billion birds can die this way annually. Surprisingly, most of these incidents aren't at very tall buildings but at shorter ones under 12 stories. Between one to three-story structures, including homes, about 44% of bird deaths occur.

About 264 bird types in the U.S. hit windows. This is almost 27% of all bird species known in the U.S. This decline risks the balance of our ecosystems and the health of bird populations.

How to Keep Birds from Flying Into Glass Door

It's key to stop birds from hitting glass doors and windows to protect them. Making the glass visible is essential. This helps birds know it's not an open area. There are many ways to do this, both inside and outside homes.

Exterior Window Modifications

One way is to add screens, netting, or decals to the glass. These should be placed close together, about not more than 2 inches apart. This way, birds can see the glass better. Shading devices like shutters, awnings can also help by reducing reflections.

Placing bird feeders and baths smartly can reduce strikes too. They should be placed either very close or far from the windows. This distance helps birds understand the glass is a barrier, and they avoid hitting it.

Inside, keeping blinds partially closed and lights off at night can make a difference. Lights confuse birds, especially at night or in low visibility. It can change the course of their flight, leading them to hit structures or other birds.

Exterior changes can help stop bird collisions. But, there are easy indoor solutions too. Homeowners can improve window visibility inside, reducing the chance of birds hitting the glass.

One simple fix is adjusting vertical blinds. Close them halfway or more. This makes glass more obvious to birds. They won’t fly into it. Also, keep shades and curtains shut, especially at night. This reduces reflections and makes it harder for birds to see through.

UV-reflective film or etching patterns help, too. They make glass look solid from the outside. But, you can still see out. These methods take advantage of how birds see their surroundings. They help make windows safer for birds.

For those wanting even more ways to prevent bird strikes, there are many options. Window decals and clings can be placed to reduce reflection. They keep birds from thinking they can fly through the glass. And, they don’t spoil your home’s look.

By using these strategies, homeowners can protect birds. Bird deaths from window collisions are a big issue in the U.S. By making windows safer, we help save local birds.

Bird-Safe Building Design and Renovation

When homeowners and developers work on properties, they can help protect birds. By using bird-safe techniques, buildings become less dangerous for these creatures. For example, they can use fritted glass windows or design angled surfaces.

Fritted glass windows have small dots of opaque material for birds to see better. Angling windows downwards stops harmful reflections. Special glass like Ornilux helps too. It looks clear to us but not to birds.

Adding patterns to windows makes birds notice them more. Even a small pattern can cut down on bird crashes a lot. This method is known as the "2-by-4 rule."

  • Fritted glass windows with closely spaced dots provide high visibility for birds
  • Angling windows downward by 20 degrees can prevent reflective hazards
  • UV-reflective glass like Ornilux is transparent to humans but visible to birds
  • Etching or sandblasting patterns on windows can make them more apparent
  • The "2-by-4 rule" states that a 5% pattern can deter 90% of bird strikes

Assisting Stunned Birds After a Collision

If a bird hits a window and looks dazed, acting fast is key to its recovery. Window strikes can cause various injuries, from head to body trauma. Immediate help is vital for the bird's health.

First, cover and gently catch the bird with a towel. Be careful not to touch it directly. Birds can get scared and hurt themselves more. Once safe, put it in a bag or box with air holes. This keeps it warm, quiet, and stress-free.

Check the bird every 30 minutes to see if it's getting better. If it starts to perk up within hours, let it go outside where it’s safe. But if it's still not well or obviously hurt, call a wildlife center for advice.

Getting quick help and sending the bird to a wildlife center really boosts its survival odds. These places know how to care for wild animals. They give them medical help, check their injuries, and get them ready to return to nature.

Don't forget, little birds, especially, can quickly lose their body heat, even when it's warm. It's important to keep the bird warm and quiet until experts can see it. This step is critical for the bird’s recovery.

Helping a stunned bird can do a lot for bird conservation. It lessens the tragic toll of window strikes. These accidents kill millions of birds every year in the U.S. and Canada.
