Have you ever accidentally walked into a glass door or wall? Don't be embarrassed; it happens now and then, especially if the glass is especially clean and you're especially distracted. Luckily, such collisions are rare, and most people shake off the effects of a bump quickly. But for millions of birds, the situation is much grimmer.
It's estimated that anywhere between 300 million and 1 billion birds die every year due to collisions with windows and other glass features. This happens in both commercial and residential buildings and has become one of the top causes of avian death. Unlike humans, most birds' eyes simply aren't capable of recognizing glass. Find out what innovations are leading the way in reducing the risk to the bird population.
One of the simplest ways to prevent bird collisions and have windows that look great at the same time is with window art. This is a great choice for residential windows, and you have a number of options that are bird-friendly and will keep your windows looking great. One option is to have frosted or etched glass windows installed. These great looking windows are stylish and energy efficient, as well as being visible to birds.
The drawback of frosted or etched glass is that it's difficult to see out of the windows. If you want to ensure that your windows are bird-friendly while preserving visibility from the inside, small window decals can be a good choice. Inexpensive static clings in nature-themed designs can be placed on the outside of the window where they won't block much of your view.
An option that can work for either commercial or residential windows are opaque films that appear clear from the inside but are visible to birds on the outside. These films prevent windows from reflecting the trees and sky surrounding the building. Such reflections can fool birds into thinking that they have a clear passage through the sky.
From the inside of the building, visibility through these films is essentially no different from visibility through clear glass. However, the birds see no reflections, and recognize the window as an obstruction that they can't fly through. What's more, the films also block the heat energy from the sun and reduce glare inside the building. That means that installing these bird friendly films helps to save energy and decrease energy costs, and make the home or building more comfortable for the humans inside.
UV Absorbing Glass
Some commercial buildings are experimenting with glass that contains ultraviolet absorbing patterns. Ultraviolet light is invisible to the human eye, but birds can see and recognize it. The glass panes that contain these ultraviolet patterns project markings that are visible to birds but invisible to humans.
So far, the UV absorbing windows have met with some limited success. The difficulty lies in the variations in avian ability to see ultraviolet light. Different species process the light differently, so it would require an extremely precise pattern and specific lighting conditions in order for the windows to be visible to all birds. However, the currently available UV absorbing glass windows are visible to some species of birds and are effective in at least reducing the incidence of window collisions. As the science behind these windows continues to develop, chances are that more even more effective UV absorbing windows will be forthcoming.
If you're in need of new windows in your home or place of business, or if you've had problems with bird collisions before, talk to your local window installer about ways to avoid window strikes. An experienced window installer will be able to help you choose glass or glass accessories that can help make your windows as bird-friendly as possible.
