On 5 December, the International Union for Conservation of Nature (IUCN) upgraded the Yellow-breasted Bunting, commonly known as the Grass Finch, from "endangered" to "critically endangered", up from "Least Concern" 13 years ago.

At present, 1,212 of the world's 9,775 species of birds are endangered, such as the large birds black stork and white stork, red-crowned crane, gray bush crane, albatross, crest, etc.

Endangered birds in China include the black stork, white stork, crested ibis, yellow-bellied horned pheasant, black-necked crane, white crane, red-crowned crane, red-necked crane, whooper swan, whooper swan, Chinese merganser, etc.

The world's endangered birds, such as the black-faced spoonbill, the kāgū, the Indian vulture, the Australian big bird, the North American migratory pigeon, the rare bird species endemic to Africa, the gray crowned crane, and 10 species of Antarctic penguins are endangered.

Of the world's 9,775 bird species, 1,212 are threatened with extinction. This number is equivalent to 1 8 of all bird species, of which 179 species are under serious threat, 344 are at high risk of extinction, and another 688 are now very rare. In almost every country and region around the world, one or more species of birds are facing extinction.

There is a high concentration of endangered species of birds in some areas, such as the Andean tropics of South America, the forested areas of the Atlantic coast of Brazil, the eastern Hima cherry blossom and the orange Raya region, the eastern island of Madagascar and the island nations of Southeast Asia.

Various species of birds are threatened with extinction, with albatross being the most threatened, with 95 albatross at the risk of extinction. 60 cranes, 29 parrots, 26 pheasants and 23 pigeons are endangered. There are fewer than 10,000 birds of 966 species and less than 2,500 of each of the 502 species threatened by the spine.

There are fewer than 50 of each of the 77 most dangerous bird species.

There were once 160,000 species of birds on Earth, and the Tertiary period was the heyday of birds. During the four major ice ages of the Pleistocene, about 25 birds went extinct and disappeared. After the advent of humans in the late Pleistocene, an average of one bird disappeared every 83 years.

1600 In the 300 years between 1900, 90 species of birds became extinct.

Among the reasons for the endangerment of birds, habitat destruction and alteration accounted for 60, human hunting accounted for 29, followed by invasive species competition, internationalization, pollution, etc.

According to surveys and estimates, the disappearance of each bird means the disappearance of 90 species of insects, 35 species of plants, and 2 3 species of fish associated with it. At the same time, for every two species of birds, one mammal is bound to disappear with it.
