摘要 朱鹮已经在地球上生存了2500多万年。作为一个物种,从兴盛到衰亡,只经历了不到一个世纪的时间。 朱鹮曾是分布于东亚的一种非常普遍的鸟类。早在十八世纪,日本一些地区的农民曾向政府反映,大群的朱鹮给稻田带来了极大的破坏,他们要求政府帮助驱逐这种有害的水鸟。到了本世纪初。 Throughout history, the Crested Ibis was a very common species of bird found in the East Asian continent. Before the middle of the 20th century, they existed in large numbers in Japan, D. P. R. Korea, Russia and China. But in the 1970s, they became totally extinct in aforesaid countries except in Yangxian County in China's Shaanxi Province. Affected by the changing environment and the presence of humans, the species that had been living in the world for more than 25 million years nearly disappeared in less than a century, becoming one of the most endangered species of bird in the world.
