Crested ibis is a rare bird, which was widely distributed in eastern China, Japanese, Russian and Korean before last century. Due to environmental deterioration and other factors, the population declined sharply and disappeared in the wild in the 1970s. Zhu has been declared extinct in Japan, Russia and North Korea.

After years of investigation, ornithologists in China rediscovered the crested ibis population in Yangxian County, Shaanxi Province in May of 198 1, which is also the only remaining population in the world. Since then, a lot of work has been done in the protection and scientific research of crested ibis, and remarkable achievements have been made. Especially in breeding, 1989 was successfully hatched for the first time in the world. From 1992, chicks can survive smoothly. By 1995, there were about 35 wild crested ibis and 25 captive crested ibis in China, which brought hope for saving this rare bird. At present, there are nearly 2000 crested ibis.

Ibis, also known as ibis, is listed as an "international protected bird" by the World Bird Association. It once lived widely in China, Korea, Japan and the Far East of the former Soviet Union. However, since the second half of this century, due to the serious influence of human activities, the habitat environment of crested ibis has been deteriorating, the distribution area has shrunk rapidly, and the population has dropped sharply. At present, it has long since disappeared in the Soviet Union. In Korea, although four were found in 1974, they were not found in 1980. In Japan, there is only one male and three females left, but they have lost their reproductive ability. In China, until May of 198 1 year, two crested ibis nests were found in Jinjiahe and Yaojiagou, Yangxian County, at an altitude of 1200- 1400 meters at the southern foot of the Qinling Mountains in Shaanxi Province, which caused great shock at home and abroad. After careful protection, the number is increasing. Crested ibis has a long beak, crested ibis and red cheeks. Its feathers are white and reddish, and its neck is covered with drooping long willow-like feathers, which is about 80 cm long. It usually lives in tall trees and flies to rice fields, swamps and mountain streams when foraging to catch locusts, frogs, small fish, snails and loaches for a living. There are many natural enemies of crested ibis. Crows and ferrets often come to fight for nests to destroy eggs and hurt young birds, so they are very strict in choosing nest areas. Generally speaking, crested ibis incubates eggs and nests, while expanding and strengthening its nests. It lays eggs in May, three or four at a time, and male and female crested ibis take turns to hatch eggs. About a month or so, the chicks hatched and were still looked after by their parents in shifts and fed together. A month later, the crested ibis gradually became full-fledged, and began to learn flying skills, and soon she could go out for food alone.

Crested ibis lives in a sparse forest area at an altitude of 1200- 1400 meters. Wading in nearby streams, swamps and rice fields, strolling for aquatic animals such as small fish, crabs, frogs and snails, and eating insects. Rest for the night in a tall tree. Residents wander to low mountains and plains in groups in autumn and winter. Nesting began in April and May, and one nest was bred every year, and each nest produced 2-4 eggs with light blue and brown spots. Hatching and brooding by parents, chicks break their shells after about 30 days and leave the nest after about 40 days.
