      I used blue to highlight the quantitative data used as evidence to support the claims made in this article.
  • two and 10 out of every 100 U.S. birds may die this way.
  • ...9 more annotations...
  • 365 million and 988 million
  • an average of 24 birds die every year at any given skyscraper,
  • a single small building may kill, on average, around two birds each year
  • Homes and other buildings that are up to three stories tall account for a far larger share: 44 percent.
  • skyscrapers are responsible for less than 1 percent of bird deaths resulting from window collisions
  • The largest share of these deaths, 56 percent, occurred when birds smashed into the windows of buildings four to 11 stories tall.
  • more than 6,500 of these lower-rise buildings for every skyscraper
  • cats may kill up to three times as many U.S. birds each year as windows do.
  • estimate the total risk posed by window glass, he and his coworkers combined the results from 23 studies of bird deaths
  •  
    Buildings in the United States can be deadly obstacles to flying birds. A new study estimates that as many as 1 billion birds die every year after colliding with windows. And low buildings - not skyscrapers - account for most of those deaths.
