New York is a major stopover for migratory birds on the Atlantic flyway, and an estimated 90,000 birds are killed by flying into buildings in New York City each year, the Audubon group says. Often, they strike the lower levels of glass facades after foraging for food in nearby parks. Some ornithologists and conservationists say such crashes are the second-leading cause of death for migrating birds, after habitat loss, with estimates of the national toll ranging up to a billion a year.
As glass office and condominium towers have proliferated in the last decade, so, too, have calls to make them less deadly to birds. The San Francisco Planning Commission adopted bird-safety standards for new buildings in July, and this month that city’s Board of Supervisors will vote on making it law. Legislation is pending in Washington that would require many federal buildings to incorporate bird-friendly designs». in The New York Times, 14 de Setembro de 2011
