Every year, artificial lighting leads to the death of millions of birds. Due to clashes with glass only in the United States, more than a billion birds die annually Climate and environment The UN and its international partners launched the campaign as part of World House Migrating Birds aimed at taking urgent & nbsp; measures to protect green zones, reducing the number of clashes of birds with buildings, light pollution and loss of habitat. ~ 60 > 62 >The theme of the campaign of this year – “General space: the creation of cities and communities friendly to birds” – emphasizes the need for joint efforts to preserve migrating birds in conditions of rapid growth of cities. Among the key threats are the loss of the environment, clashes with windows, light pollution and death from pets. The campaign calls to attract residents of cities in the protection of birds. & Amp; NBSP; World Migrating Day is spent twice a year, which allows migration peaks in both hemispheres of the Earth. The campaign discusses various aspects of & nbsp; protection of birds and their habitat. In 2025, the emphasis was on stable urban planning, initiatives to create safe conditions for birds and the participation of local communities. & Amp; NBSP; 49 percent of populations of all species of birds in the world are threatened with reduction, and every eight is threatened with disappearance. According to the latest data, 49 percent of the populations of all species of birds in the world are threatened with reduction, and every eight is threatened with disappearance. Most of all & nbsp; this applies to migrating birds. The study of 2024 showed that 80 percent of bird species cannot fully adapt to the environment controlled by a person. & Amp; NBSP; in Germany, about 100 million birds die annually due to clashes with glass, more than a billion in the United States. In the Republic of Korea, about 186 thousand birds per year die from blows on noise -defering screens along roads. Artificial light knocks down birds from the course, increasing the risk of clashes: in 2023, about a thousand birds crashed against the building in Chicago. & Amp; nbsp; Electricians restore a stork nest. The noise prevents the birds from communicating, looking for partners and multiply. In Munich, scientists found that the chicks of the zebra Amadin, who hatched in a noisy environment, were smaller than usual. Populations are also threatened with & nbsp; cats: in Canada they kill up to 350 million birds per year, in Australia – more than a million per day. & Amp; nbsp; taking into account the fact that 55 percent of the world’s population already lives in cities, and by 2050 this share will grow to 68 percent, it is necessary to revise the approaches to the planning of cities so that they become safe for birds and safe for birds and birds useful for people, scientists note. & nbsp; 80 percent of bird species cannot fully adapt to the environment controlled by a person. recommendations of the 2025 campaign & nbsp; • plan cities taking into account the interests of birds; • plant local plants; • prevent collisions with glass using films; • turn off the light at night; • avoid the use of pesticides; • reduce plastic waste volumes; • keep cats at home or in closed enclosures; • increase awareness of this problem and train the local community.
