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 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.
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.
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 passage in the reading talks about the injuries of wild brids caused by glasses in the buildings and presents three ways to solve this. The lecturer, however, refutes these solutions by stating them to be ineffective.
Firstly, the reading proposes to use one-way glass in the buildings, so that the bird will not see through them and will perceive it as a solid barrier and will avoid it. But, the lecturer points out that the one-way glass is just as bad as the regular glass as the one-way glass acts as a mirror. If the birds see the reflection of sky or a tree on the one-way glass they will perceive it as the open air and will try to fly through it. So, this solution will not work.
Secondly, the passage suggests to paint the glass windows with stripes. The birds will then avoid flying through by seeing the stripes. The lecturer, however, rebuts this idea by stating that the birds will consider the unpainted portion of the glass to be holes or openings, which will lead them to try to fly through them. To prevent this, the unpainted portions of the glasses need to be very small. But, this will make the interior of the building darker as there will less light passing through the small openings.
Finally, the passage posits to create and use artificial magnetic field to steer away the birds from the path of the building. This idea is based on the knowledge that birds use earth's magnetic field to navigate. Although, the lecturer agrees with the passage that birds use earth's magnetic field to navigate, he added that bidrs use this navigation technique only while the are migrating from one country to another. They don't use the magnetic field to navigate for shorter routes like moving from one end of the city to another end. In addition, he said that, for this shorter distances birds depends on their eyes and the brightness of the light. So, this solution will not be effective too.
