Scientists stated the reason for annual death of millions of birds in the USA


At least 100 million birds annually die as a result of blows about the buildings which are mainly glazed and the lit skyscrapers. Skyscrapers are one of the main reasons for annual death of at least 100 million birds in the USA, and the most disturbing situation is in the field observed in Chicago. The group of the American scientists after the research conducted by them which results were reported by the British newspaper The Guardian came to such conclusion. Ornithologists from Cornell University studied the main sources of threats for birds and made the list of the American cities, most dangerous to their accommodation. Results showed that at least 100 million birds annually die as a result of blows about the buildings which are mainly glazed and the lit skyscrapers. Chicago which is filled with various skyscrapers became the most dangerous city for them. Through it the majority of migration routes of migratory birds lies. Scientists found out that every spring and fall through the center of Chicago about 5 million feathery travelers of 250 different types fly by. They migrate two times a year, covering the distance to thousands of kilometers. In the spring of a bird go from Central and South America through the Great Lakes to Canada, and come back to the south in the fall. The second and third place in this list was taken by Houston and Dallas. These Texas cities are also located on the way of migration flows of birds. They are followed by New York, Los Angeles, St. Louis and Atlanta. Scientists specify that the majority of the birds migrating through the USA make the flights at night, and most often their routes lie through well lit cities. According to experts, birds are attracted by light and when they fly over fires of big cities, do not even suspect about the danger trapping them. To protect them during mass migrations, ecologists suggest to disconnect electricity in buildings at night. Besides, experts support use of figured glass and the muffled lighting at construction of skyscrapers. "We need to coexist with an ecosystem as we are its part as well as birds, - the representative of National Odyubonovsky society ornithologist Suzann Elbin emphasized. - What is good for birds, it is good also for people".
