Both of the provided materials are discussing protecting flying birds against the glass for birds can harm themselves by moving right into them, not being able to distinguish between open-air and glass surfaces. Then the reading proposes three solutions for this issue. Later, the lecturer refutes each of them since he believes none could be effective due to the nature of the birds.
First, the reading suggests that using one-way glass, glass which can only be seen through from one side, instead of regular glass would help the birds to discriminate the obstacle from the freeway and, consequently, change their direction. However, the professor opposes this point by stating that one-way glass is as harmful as ordinary glass to birds because the side that is not transparent has to be reflective. So, when birds see a reflection of the sun or any landscape, they assume it is an open area and will try to fly through. Thus, the inability of birds to grasp the concept of the mirror will overturn this idea.
Second, the reading avers another scheme that is using specific patterns on the glass while constructing it in order for birds to see it. The lecturer finds this solution hopeless since the openings between patterns say spaces between stripes, are still interpreted as open holes by birds. Therefore, they will try to pass the obstacle by flying through the openings. Moreover, for the birds to move around the building, the openings have to be really small; But that way, the rooms will be dark and somewhat not useful anymore. Again, the way that birds' minds work surpassed the second method.
Third, the reading makes another proposal by stating that artificial magnetic fields can help the birds to steer their ways around the buildings. Nonetheless, the professor explains even though it is true that birds rely on earth's magnetic field for navigation, but this is just the case in long trips, say intercontinental migrations. For a short journey across a city, birds use the lights and their perceptive organisms. So, the third proposal has its own drawbacks, as well.
