Strategy of preventing birds from bumping into the windows of buildings

The reading and the listening both talk about the strategy of preventing birds from bumping into the windows of buildings. The article suggests that there are three methods of protecting birds. However, the speaker doesn’t agree with this with the following arguments. First of all, the author says that the windows with one-way glasses can ideally prevent birds from harm because birds can not see through the windows due to their transparency in one direction. Thus, birds will not fly into these windows. Nevertheless, the lecturer argues that these windows can still reflect the trees in surroundings and might still make birds confused. Therefore, the windows with one-way glass may still confuse birds and make them go into the windows. Second, it is said in the passage that using colorful windows can protect birds from going into. However, the speaker disputes that we may have very small and unpainted windows nearby the colorful windows. Nevertheless, these small windows are not practical because they will make the inside room too dark. Finally, the author also advises to change the magnetic fields surronding the buildings so that we can make birds not to go into windows. In contrast, the speaker argues that this method won’t work since birds only follow magnetic field in a long distance and not a short distance in cities.
