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 passage is mainly about three solutions which can avoid glass to make birds injured. However, the professor in the lecture disagrees. He thinks that none of these solutions can stop birds from injuring.
First of all, the one-way glass would look like mirror from outside of building, which means that it would reflect sky or trees. Nevertheless, birds can not understand mirror, and they would perceive these reflections as the real sky and trees. In turn, birds would hit one-way glass because they think it is open air.
Second, it is not possible for colorful designs to reduce birds injury. To be more specific, birds would perceive the openings of the strips as open holes, and fly right though them. In contrast, if the strips are extremely closed to each other, then it would be too dark for people who stay inside of the building.
Thrid, the solution of creating an artificial magnetic field would not work at all. The professor refutes the statement by giving the fact that, birds only nevigate by magnetic field while they are travelling for long distance. Instead of migration from cold place to warm place, travelling from one city to another city only require the sight of the birds and the blight of the lights. That is why the artificial magnetic field can not successfully guide birds way from buildings.
To sum up, the professor disagrees the three solutions, one-way glass, colorful design and magnetic field in the article by providing further explanations to proof that they are not effective solutions for prevent injuries to birds.
