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 writer proposes three solutions to prevent birds from crashing into windows, for them cannot distinguish between glass and open air. The lecturer, however, challenge all these solutions. He is of opinion that none of these solutions are convincing.
The passage states that birds cannot see through one-way glass and therefore they will not understand that the glass form a solid barrier. Nevertheless, the speech points out that one-way glass will reflect like a mirror and causes another trouble for birds. Since birds don't understand mirrors, they will think the sky or tree on the mirror are the real one and fly into them.
The writer asserts that the colorful design will serves as a caution to birds not to fly through it. Conversely, the speaker says that birds are not able to understand this caution. Birds will perceive the spaces between the stripes as holes and fly through it. If people want to stop birds to crush into the window, then they have to make the spaces between the stripes small and that in turn will make people inside the building uncomfortable.
The writer mentions that we can create artificial magnetic field to guide birds away from buildings since birds have natural ability to sense Earth's magnetic fields. However, the speaker points out that setting artificial magnetic field will not be effective. Birds typically use the magnetic organ to guide their flying over long distance like migrating from cold to hot country before winter. In short distances, however, birds will not sense these artificial magnetic field, so artificial magnetic field can't be a practical approach.
