Tehran – Light shining through the glass of buildings at night blinds migratory birds and kills many migratory birds each year.
Each year, many artificial light sources hit the adjacent glass-enclosed buildings, killing many migratory birds.
World Migratory Bird Day is a campaign to raise awareness and highlight the protection of migratory birds and their habitats. Every year, the second Saturday of May and October is known as World Migratory Bird Day.
This year, October 21st is World Winter Migratory Bird Day and the slogan was ‘Turn off the lights so migratory birds can get home safely’.
Too much light or reflections on glass or walls kill thousands of birds each year. This is because some birds look to light sources such as stars, the moon, or other natural light at night. Instinctively, they are accustomed to seeing it and moving towards it.
Ornithologist Alireza Hashemi said in an interview with ISNA that some birds migrate during the day and others at night. At night, birds rely on light, such as starlight, to guide their migration routes, but excessive light pollution disrupts their migration routes.
In fact, many of the world’s skyscrapers, he lamented, kill thousands of birds each year because they don’t create the right environment and conditions for them.
Industry often stores pollutants such as oil wells and oil wells as open ponds, the surface of which glows with light, and birds see these ponds as waterbeds to land on.
If the environment is heavily polluted, they will die quickly. If these ponds contain oil, they will become trapped after landing due to the high viscosity of the oil.
In addition to light pollution, air pollution, water pollution, and food contamination also affect bird health. In Iran, not many detailed studies have been done on birds, but he said air pollution has a devastating effect on birds because of their special respiratory system.
There are several sources of contamination in food because some heavy metals do not enter the body and are not eliminated, they accumulate and kill the bird in one fell swoop, adversely affecting reproduction even if the bird does not die. As a result, the population will decline.
Migratory birds do not belong to just one habitat or country. He stressed that collective will and international solidarity are needed to care for migratory birds and to protect and keep environmental tips safe.
Iran hosting migratory bird species
The annual survey of migratory birds in Iran begins in the middle of the Iranian month of Day (December 22-January 20) and ends in the middle of the month of Bahman (January 21-February 19). Number of migratory birds traveling from north to south countries due to seasonal cooling and reduced food availability.
About 61,493 migratory birds are on the IUCN Red List and have been observed in a variety of locations, including Dalmatian pelicans, little geese, white-fronted geese, spotted ducks, marble ducks, teals, Siberian cranes and giant knots. part of the country.
The largest population of IUCN Red List migratory birds belonged to common Carrionidae species of 53,882 birds, and the smallest populations belonged to two species, the Siberian Crane (1 bird) and the Black-headed Goose (2 birds).
The states of Mazandaran, Golestan and Gilan see the highest number of migratory waterfowl and shorebirds in winter.
About 15,000 troops, many of them volunteers, participate each year, and migratory waterbirds and shorebirds are counted in over 100 countries.
