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 lecturer challenges the topic proposed in the reading that several solutions that responsible businesses can use to prevent injuries to birds. And he thinks that none of these solutions would effectively stop birds getting injuries.
First, the passage indicates a solution is replacing the regular clear glass with one-way glass that is transparent in only one direction. However, the professor points out that the one-way glass is as bad as the regular glass. In that the one-way glass as a mirror which reflects the sky and trees, birds cannot understand mirrors, so they would see the mirror just as the sky and trees and want to fly into them. Thus, the first solution is untenable.
Second, the essay mentions another solution is to paint colorful lines or other designs on regular window glass. But the lecturer argues that designs including openings would be like to open holes, which would engender birds to fly through them. To avoid this, the unpainted parts of the window must be considerably small, but it is too dark for the people inside the room. Hence, the second solution is also tenuous.
Third, the article supposes another solution is to create an artificial magnetic field to guide birds away from buildings. Nevertheless, the lecturer supports that birds merely utilize Earth's magnetic fields to travel a long distance, such as flying from a cold country to a warmer one before winter. And they use eyes and lights to travel a short distance such as from one side of the city to another side. Consequently, the artificial magnetic field would not have effect that guiding birds away from buildings.
