This article addresses the issue of bird deaths in New York City resulting from birds flying into the windows of tall buildings. The New York City Audubon estimates that 90,000 birds are killed by flying into buildings in the city each year.

Since 1997, the New York City Audubon has collected nearly 6,000 deceased birds as part of a monitoring program that collects and documents dead birds during migratory season. Through this program, they have identified a few high-risk locations and recommended architectural structures that would help ease the problem.

One building with reflective glass, which reflected a line of trees, was particularly deadly, leaving 300 birds dead in 2006. They voluntarily placed opaque covers on the windows, resulting in no deaths the following year. Some architects and companies are working on window designs to avoid collisions with birds. There are also programs in place to provide incentives for bird-friendly modifications to buildings.
