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 reading and the lecture both discuss solutions that can prevent birds to colliding with window glasses. The passage provides three solutions, but the lecturer points out problems of each solution.
First, the author suggests using one-way glasses, that are transparent in only one direction. However the professor contradicts this solution by mentioning that although birds on the outside can't see the glasses, however these glasses look like mirrors on the other side, and birds don't understand mirrors. So, if a bird sees the reflection of sky or a tree on these glasses, they might fly right through them and hurt themselves seriously.
Second, the passage suggests using colorful designs on window glasses. However, the lecturer reasons that despite these designs still the birds will fly through the holes in these designs and will get injured. To overcome this issue the holes between these designs should be very small, to prevent birds from flying into them. Furthermore making these holes very small will make rooms of the building too dark. So, using designs does not seem to be a possible solution.
Third, the reading mentions birds ability to navigate by magnetic field, and suggests to use artificial magnetic field to misguide the birds and move them away from the window glasses. Meanwhile, the professor rebuts this solution and mentions that birds just use this navigation system on very long trips, like travelling from cold to warm places, and for short distance trips they use their eyes and brightness. Considering this fact, this solution is deemed as unsuitable too.
