According to news on October 9, the development of human urbanization will inevitably have many negative impacts on nature. The most common one is birds hitting buildings. No, a large-scale collective bird collision occurred recently. According to a US media report on October 7,Nearly 1,000 birds died after crashing into the windows of Chicago's McCormick Place on the evening of the 4th, the bodies were piled like a carpet.
Stotts, an ecologist at the Field Museum of Natural History in Chicago, said that so many birds died overnight, indicating that a large number of birds were migrating here. According to reports, from the evening of the 4th to the early morning of the 5th, the number of migratory birds over Chicago reached a peak of about 1.5 million.
Stotts said the combination of rain and the lights at the convention center had fatal consequences.Bad weather makes it difficult for birds to locate, urban light pollution attracts them, and reflections from glass windows cause them to crash into, and Chicago's McCormick Place is the largest convention and exhibition center in North America. Most of its building exterior walls are covered with glass.
Researchers estimate that about 100 million birds hit windows and die every year in the United States, and bird ecologists say that similar incidents can be prevented by dimming lights and putting markings for easy identification of birds.
