When the sun goes down, there is a cry of “gaga” by the Taihua River in Ulsan, South Korea. Hundreds of winter crows went out together, and the whole sky was covered with black pressure.
An article in South Korea’s Central Daily on the 16th described the above scene. According to the report, for those who see this picture for the first time, this is tantamount to “large-scale horror film scene”.
According to the report, these crows are bald-nosed crows, mainly living in Siberia and the Mongolian grasslands. They have been operating in Ulsan, South Korea since 2000. At present, 100,000 crows have stayed in Ulsan for the winter.
These crows are short and not as big as the palms of adults, not counting wings. At first glance, these crows seem to wander disorderly in the sky, but in fact act collectively. The reason why the bald-nosed crow did this is to protect themselves from natural enemies such as the eagle owl. Whenever there is a sun, these crows gather above the farmland and eat some falling grain.
In addition to Ulsan, people often see this kind of crow in Gyeonggi Province, Suwon and other places. Compared with other regions, there are fewer complaints about crow excreta and noise in Ulsan, because they mainly operate on inaccessible rivers and woods rather than in urban areas.
