These two days were Xiaobao's happiest moments, and his mother did not return to the provincial capital, but spent it with the little one. At the same time of high-speed update, everyone also taught Xiaobao to know a lot of things.

At this time, the students of the school are also preparing for the holidays, and the elementary school in the village begins to prepare for the exams, preparing for the exams tomorrow and the day after tomorrow. Because there are only two teachers in the primary school in the village, there are four grades from preschool to third grade, so there is a shortage of manpower. Therefore, Teacher Liu asked the Chu family to help invigilate the exam.

In view of the lack of teachers in the village, the village has applied to the town, hoping to have new teachers to settle in Chujiazhai. In the past, because Chujiazhai was a small village, this primary school was just a branch school, and when students reached the fourth grade, they were given a main school two or three kilometers away, and when they reached the fifth grade, they had to live in the school.

In fact, there are not many students in the village, and there are about 30 people in each grade. As a result, in the past, two grades sat in one classroom and one teacher coped with two grades. It can be said that a student can listen to two grades at the same time.

However, this practice is very bad and will affect the quality of teaching. If you think about it, you will understand. Preschool students are doing their homework on their own, and the teacher is teaching the first grade class on the side, can it not have an impact?

Therefore, in backward rural areas, unless you are really talented and hard-working, you can make some achievements. In rural areas, college students are so rare, and this is the reason.

Chu Jiaqiang, who was sitting at the door of his house reading a book, suddenly saw Ding Jianhui and others hurriedly passing by the door, as if they were about to rush towards the reservoir. He thought it was what happened to those swans, so he asked, "Dean Ding, what's the matter?" In such a hurry?"

"Haha! Good thing, if you want to know, follow along. After saying that, Dean Ding's group had already walked away.

"A good thing?" Chu Jiaqiang was stunned for a moment, a little curious. So, put the books away. During this time, he would always scoop out these medical books and take a few glances when he had time, and he would always gain something.

Liang Yu and others thought there was a lively look. It's been followed for a long time. When Chu Jiaqiang arrived, he found that many people were watching, all looking in the direction of the island.

When he fixed his eyes, he found a flock of birds, not many of them. That's twenty or thirty. Chu Jiaqiang had never seen this kind of bird. It's weird. Looking at the expressions of Dean Ding, Professor Wen and others, you can know that this bird should be quite precious and scarce.

I saw that they were beautiful and elegant, and their actions were dignified and generous. It's beautiful. Unlike other classes, its head is bare and vermilion-colored only on its cheeks, its iris is orange-red, and its black mouth is elongated and curved downward. The back of the occipital part also has a willow-shaped crown of dozens of thick feathers, which is scattered over the neck. The legs are not too long, the lower part of the shin is bare, and the color is also vermilion. The feathers are as white as snow, but the underside of the two wings and part of the round tail feathers shine with vermilion, which is elegant and beautiful.

"What kind of bird is this?" Chu Jiaqiang asked.

"Crested ibis, haven't you heard of it? This is a protected animal in our country, which is very rare, similar to the South China tiger. The wild ones are basically gone. Professor Wen said with a smile.

The crested ibis lives in temperate montane forests and hilly areas, mostly near wetland environments such as rice paddies, river beaches, ponds, streams and swamps. Withdrawn and quiet, timid and fearful, usually in pairs or small groups.

They are more demanding in terms of habitat conditions and only prefer tall trees to roost and nest in. There are paddy fields and swamps nearby to feed, and there are relatively few natural predators. Spend the night in large trees, and during the day, forage in rice fields, mud or land where no chemical fertilizers or pesticides have been applied, and clean streams.

"This bird is docile because of its temperament. The folk regard it as a symbol of good luck and call it the 'auspicious bird'. I didn't expect there to be wild ones, what a surprise. It seems that it should still be a migratory bird that flew out of the Yunkai Mountain, not a flying down. Fu Shenglin looked excited, and his eyes were tightly watching the figure that flew gracefully at that time, and sometimes landed on the big banyan tree.

"Huh! It's a treasure trove of rare animals. Dean Ding was undoubtedly the happiest, seeing this extinct animal run out again.

Only then did Chu Jiaqiang know that this was the crested ibis. He had heard of crested ibis, and he had heard that a few were accidentally found in the north, which caused a great shock.

The crested ibis is a rare bird, and it has been widely distributed in East Asia, including eastern China, Russia, North Korea and other places. Since the middle of the 20th century, due to the impact of human social production activities on the environment, mainly due to the reduction of the number of winter paddy fields, the pollution of chemical fertilizers and pesticides, the reduction of forests and human disturbance, etc., it is difficult for the crested ibis to adapt to the changed environment, and its number has decreased sharply.

"Now, this rare bird is only available in our country, and it is already a unique species in our country, hehe!" Professor Wen explained.

In the twenties, it was thought that the crested ibis in Nimoto no longer existed, but later a small number of individuals were found to be present on the Sado and Noto Peninsulas. At the end of the sixties, the crested ibis disappeared in the former Soviet Union, and disappeared from the Korean Peninsula in the seventies and eighties. However, several more were soon found in Yangxian County, Shaanxi Province.

At that time, it can be said that the crested ibis was much more precious than the giant panda. Later, the seven were bred in captivity, and the number has reached thousands. Unfortunately, these are not wild, and after such a long time of domestication, and then released into the wild, they may face extinction again.

"You don't know! At that time, it took a lot of manpower and material resources to find the seven crested ibises to keep what they thought was the last spark. Fu Shenglin recalled the situation at that time, and he was also full of feelings.

"Ugh! Didn't you say that it was discovered by accident?". Chu Jiaqiang was stunned.

"Where is there so much unintentional? At that time, ornithologists from the Institute of Zoology of the Chinese Academy of Sciences formed an expedition team to investigate the three major regions of Northeast China, North China and Northwest China, spanning nine provinces and regions, and traveling more than 50,000 kilometers. It was even more arduous and difficult than the Red Army's Long March. Professor Wen shook his head.

Among the humanistic values of the crested ibis, the crested ibis provides a rare place and opportunity for human beings to explore the mysteries of nature. The process of its discovery and rescue alone has excited the scientific community. As an extremely special animal species, it still has high human value while having high ecological value. It is mainly manifested in science, economy, culture, aesthetics and sociology.

In Riben, the crested ibis is known as a sacred bird, but unfortunately, their native sacred bird is still extinct. Only by relying on China's gifts from time to time, or borrowing a few times, can the crested ibis not really disappear in their homeland. ()
