Why Can T Birds See Glass?

There are a lot of things that birds can do that we can’t. They can fly, for one. But there’s one thing that they apparently can’t do, and that’s see glass.

Birds will often fly into glass doors and windows, thinking that they’re open space. This is a problem not just for the bird, but also for the owner of the glass door or window. Not only does it mean having to clean up a dead bird, but it also means replacing broken glass.

So why can’t birds see glass? The answer has to do with the way that light reflects off of glass. When light hits a pane of glass, some of it passes through the glass while some of it is reflected back.

Birds rely on their vision to help them navigate, and when they see an open space in front of them, they fly towards it. But with glass, the light is reflected back in such a way that it looks like there’s an open space behind the pane of glass when there isn’t actually anything there.

Have you ever wondered why birds seem to fly into windows? It’s not because they’re not paying attention – they simply can’t see the glass! Birds have very good eyesight, but they see differently than we do.

They can see ultraviolet light that we can’t, which helps them find food and mates. But this also means that they don’t see the difference between a pane of glass and the open air beyond it. So if you have a bird feeder near your window, be sure to keep an eye out for errant feathered friends!

And if you do see a bird hit your window, don’t worry – they usually bounce right off without any harm done.

-How Does Glass Fool Birds

Birds are naturally attracted to shiny objects, and glass is no exception. However, when birds try to land on a glass window or surface, they often end up crashing into it. This is because birds mistake the reflection of the sky in the glass for an open space.

Glass also fools birds because it is transparent and therefore difficult for them to see. As a result, birds often fly into windows and other glass surfaces without realizing they are there. While this can be dangerous for the birds, it is also a major problem for people who live in areas where there are a lot of bird-window collisions.

In fact, these collisions kill an estimated 1 billion birds every year in the United States alone.


Birds are often seen flying into glass windows, and the question of why they can’t see the glass is a common one. It turns out that there are a few reasons for this. First, birds have relatively poor eyesight compared to humans.

This means that they may not be able to see the glass as clearly as we can. Additionally, birds are attracted to reflections in glass, which makes it even harder for them to see the actual window. Finally, some birds mistake reflections of trees or other objects for real things, and try to fly into them.

Welcome to birdsbeast.com! I created The Birds Beast to share my passion for all things birds with the rest of the world. I also belong to a professional group devoted to birds, and as a means of outreach, I use this blog to help as many people as I possibly can. Birds are some of the least treated pets in the United States. It is my fervent desire to change this, and I hope my blogging will motivate meaningful actions and allow individuals to safely handle their birds.
