The reflective towers of New York City, which is on the Atlantic migrating (遷徙的) route, can be deadly for birds.“We live in an age of glass,” said Ms. Laurel,an architect. “It can be a perfect mirror in cer tain lights， and the larger the glass， the more dangerous it is.”About 90, 000 birds are killed by flying into building in the city each year. Often, they strike the lower levels of glass towers after searching for food in nearby parks. Such crashes are the second- leading cause of death for migrating birds, after habitat 1oss，writh an estimated number of death ranging up to a billion a year.
As glass office and apar tment towers have increased in the last decade, so, too, have calls to make them less deadly to birds. San Francisco adopted bird-safety standard for new building in July. The United States Green Building Counci1，a nonprofit industry group that encourages the creation of envir onmentally conscious buildings, will introduce a bird-safety credit this fall as part of its envir onmental certification process.
There are no easy fixes, however. A few researchers are exploring glass designs that use ul traviolet (紫外線的) signal1s, but they are still in their inf ancy. Covers, dot patterns, shades and net are the main options available.
0ften，only one section of a building needs to be changed. “ You don’ t necessarily have to treat every window,Ms. Laurel said.“It would be too expensive to do the whole building.”The Jacob K. Javits Convention Center, which has been undergoing alterations, is the most recent building to voluntarily correct the problem of bird crashes. The architects used less reflective glass and dot patterns.
