Researchers finding solutions to bird/building collisions

Glass facades cause an estimated 750 million bird deaths each year, according to estimates by the U.S. Fish and Wildlife Service.

At some properties, the problem is so bad that skyscraper owners hire workers to remove dead birds from the base of their buildings. To address the problem, the American Bird Conservancy created two avian research facilities at the Powdermill Nature Reserve near Pittsburgh and another inside a modified shipping container at the Bronx Zoo.
