From USA Today. It is nice to know that with all the problems in this country, the San Francisco Board of Supervisors is working on what’s really important, making sure that birds don’t fly into buildings.
An ordinance approved Tuesday by the Board of Supervisors requires that new buildings in parts of the city use “bird-safe” standards that reduce the risk of winged creatures hitting panes of glass.
Advocates say that hundreds of millions of birds die each year after flying into glass windows or walls in the USA, and that San Francisco’s action will boost efforts to encourage bird-safe buildings nationally.
“It’s a global problem,” says Christine Sheppard, bird collisions campaign manager for the American Bird Conservancy. “Everywhere you find glass, you will find dead birds. One of the reasons that people don’t recognize it is a problem is that it is so widely distributed. There are some buildings that kill thousands of birds a year.”
Transparent and reflective glass both pose a threat to migratory and local birds, Sheppard says. Birds don’t see glass or recognize it as a barrier and think they are flying to vegetation they see through the window or in a reflection, she says.
Marking windows with dots or other designs, or shielding the glass with screens or other architectural devices, can reduce fatal accidents, Sheppard says.
Isn’t this something that evolution should take care of? I mean the birds that can’t see the glass will kill themselves while the birds that can will live on to reproduce and improve the various species. Natural selection and survival of the fittest in action.
