Glass is a favored building material for modern architecture, yet it is also very dangerous for wild birds. Because they often cannot distinguish between glass and open air, millions of birds are harmed every year when they try to fly through glass windows. There are, however, several solutions that responsible businesses can use to prevent injuries to birds.
One-Way Glass
One solution is to replace the regular, clear glass with one-way glass that is transparent in only one direction. The occupants of the building can see out, but birds and others cannot see in. If birds cannot see through a window, they will understand that the glass forms a solid barrier and will not try to fly through it.
Colorful Designs
A second solution is to paint colorful lines or other designs on regular window glass. For example, a window could have a design of thin stripes painted over the glass. People would still be able to see through the openings in the design where there is no paint, while birds would see the stripes and thus avoid trying to fly through the glass. Architects can be encouraged to include colorful painted patterns on glass as part of the general design of buildings.
Magnetic Field
The third solution is to create an artificial magnetic field to guide birds away from buildings. Humans use an instrument called a magnetic compass to determine directions—either north, south, east, or west. Bird research has shown that birds have a natural ability to sense Earth’s magnetic fields; this ability works just like a compass, and it helps birds navigate in the right direction when they fly. A building in a bird flight path can be equipped with powerful electromagnets that emit magnetic signals that steer birds in a direction away from the building.
The article discusses the effect of using glass in buildings on harming the birds that cannot recognize it and try to fly through glass windows and suggests three ways to prevent injuries. However, the professor thinks that none of these methods will stop the birds from harming and refutes each of the author's reasons.
First, the passage claims that using one-way glass is an effective method. One-way glass enables the people indoor to see the outside but from the outdoor neither the birds nor humans can see inside the building. However, the professor states that this kind of glass act just like a mirror and reflects the natural views of the outside, hence, the birds would not be able to differentiate between the actual view and the reflection and as a result they would try to fly toward them.
Second, the reading states that architects can use colorful designs on the glass such as painting colorful strips on the glass which not only does maintain the ability of the occupants to see outside but also will prevent the birds from colliding into them. However, the professor claims that the bird would assume the free un-painted area as holes and would try to fly through them.
Third, the article states that generating magnetic field around buildings will help the birds to recognize the building since they have the ability to detect the earth's magnetic field and use it as an aid for navigating, hence the artificial magnetic field will distract them from the buildings. Nevertheless, the lecturer refutes the effectiveness of this method by saying that the birds use this ability just for long trips, for example when they are migrating. In short trips, like trips in a city, they use their eye and the brightness to find their way.
