This postcard image shows bright yellow exterior lighting on the façade of the gigantic McCormick Place Convention Center. Scientists have blamed its exterior lighting for confusing migrating birds, as thousands have collided into the building and died over the years. In 2002, bird deaths decreased by 80% after the building shut off its exterior lighting, according to officials at the Field Museum. Now other buildings in Chicago are doing the same to help save birds. The McCormick Place opened in 1960 and is situated on about 30 acres of land on Lake Michigan.
