As the makers of glass are innovating to avoid collisions of birds

Every year, between 365 million and 988 million birds die in the United States, due to collisions with buildings and homes, according to a report by BioOne. To work around this problem, several companies that manufacture Windows and glass are researching ways to begin to reduce the large number of deadly collisions. Using innovation, of course.

According to The New York Times, more and more American cities and States, like San Francisco and Minnesota, to adopt standards that promote the safety of birds. But this may not be enough.

"Almost everyone has seen or heard a bird hitting against a building. Companies who manufacture the glasses are realizing that there is a market for the product (s) friends of the birds, "explained to NPR Christine Sheppard, an activist against bird collisions of American Bird Conservancy.

One of the ideas, which is being tested by researchers at Fordham University, ponders add small white and black vertical strips to Windows, to prevent the birds go against these.

During the experiments, when the birds go into wind tunnels partially blocked by glass listed, they tend to avoid the lists. Another idea, less intrusive but more expensive, was proposed by Arnold Glas glass manufacturer. The company has developed a standardized reflective coating and ultraviolet, which has the advantage of being almost transparent to the human eye but detectable by birds.

Not only are the Windows that are causing problems, but also how they are used. The large mirrored facades, for example, are particularly dangerous for migratory birds. Thus, Fordham researchers are trying to figure out exactly how much space they can put between the lists, in large pieces of glass. If they can find the "G-spot" acceptable to architects and can repel the birds, this may be a plausible solution.
