Although the singing stopped on the radio, netizens were still immersed in sad and moving emotions for a long time, and aftertaste the beautiful dance of the Red Crowned Crane just now.

Some people even turned on the player, searched the song and listened carefully again.

Fang Ye looked at the cranes flying on the lake and didn''t say anything for a long time.

After a while, the mood eased a little and asked, "how is it? Is it different from listening to this song when I was a child?"

"Well, I was scared when I listened to this song when I was a child! I think the girl died miserably. Now I can understand the emotion when I listen to it again."

Fang Ye added: "although Xu Xiujuan''s deeds are very touching, I still want to tell you that bringing the Red Crowned Crane to winter breeding may be of scientific research value, but from the perspective of nature protection, it needs to be treated seriously.

Domestication of red crowned cranes has changed the habits of red crowned cranes. Now the red crowned cranes cultured in the reserve still face many difficulties in reintroduction, which is different from the real wild red crowned cranes.

Will the artificially bred red crowned cranes return to the wild population have disease infection? Will it change the habits of wild red crowned cranes?

According to the statistics of the previous two years, the number of wild red crowned cranes in China is only 500, which has always been an endangered state, but the number of captive cranes has reached 2500. At present, there is no record of large-scale successful wild release of red crowned cranes.

There are also some commercial flying performances of captive red crowned cranes in the reserve. They take eggs from the Wild Red Crowned Crane nest and sell them to the zoo. They are called protection, but they are actually profitable. All these are existing problems.

Wild red crowned cranes are very alert. If someone enters their territory, they may directly abandon their nest.

Even if they pick up the eggs, they will make up the eggs. The hatching time of the baby cranes is delayed, the feathers are uneven and can not migrate. The red crowned cranes will stay in the northeast with their children and can not survive the winter. This is also the reason why the Wild Red Crowned Crane population has been unable to grow. "

"Ah? How angry!"

"I can''t accept it! How can I treat them like this?"

"Headmaster, did you buy your crane from the reserve?"

Fang Ye explained, "our red crowned cranes were introduced from other zoos. In fact, the first animals in the zoo were captured from the wild, but it''s not appropriate to do this again now. Can you understand this?"

"I can understand! I would have thought zoos shouldn''t exist before. But after watching the live broadcast of the director, I know what a really good zoo is like."

"Yes, zoos are not only places of entertainment, but also educational."

Fang ye said, "therefore, the best expression of love is to really love red crowned cranes and protect their habitat.

Let''s go and see our new hippos and giraffes. "

……

Come to the back of the hippo Pavilion.

The rear house of Hippo Pavilion is different from other buildings. Because hippos need water to live, in addition to the normal animal house, the next room is equipped with a small pool.

However, the pool looks dirty and not very clear.

There are some grass leaf residues floating on the water surface, and some spherical things can be seen at the bottom of the water. It looks like shit eggs.

The breeder Lao Gang is an uncle in his forties. He will hold a pineapple and another bucket. Across the railing, he laughs and shouts the hippo''s name: "Dudu? Dudu?"

Dudu''s huge dark brown body is mostly submerged in the water, with his back, nose and eyes exposed.

Small eyes looked at Lao Gang, suddenly his head shook, patted the water, and made a loud sound! It''s like a gun battle in the water.

A spray of water was lifted up. Although the old man had just left for a distance, some small drops of water were thrown on his face.

Fang ye and the blue carp saw this scene as soon as they came. The blue carp was startled by the loud noise. He quickly hid behind Fang ye and looked out carefully.

Lao Gang seemed to be used to it. He wiped the water on his face, stood up, greeted Fang ye and said, "the head of the garden is coming! Ah, Dudu doesn''t seem to like me very much!"

Dudu at this time, his nostrils sprayed again, spraying a spray of water, as if expressing his dissatisfaction.

Fang ye said with a smile, "Dudu is a timid character."

Some netizens wondered, "the environment looks a little dirty. Don''t you clean it?"

"Yes, the water is so muddy! Be diligent."

"Of course hippos are unhappy with such dirty water."

Fang Ye looked at the bullet screen and said, "I don''t know if you''ve seen a news that there are a lot of belly turning dead fish on the African river. The investigation found that they were smoked by Hippo shit?

It sounds a little crazy, but it''s true!

The idea of fumigation is a bit exaggerated. To be exact, fish died due to hypoxia. There are a large number of undigested plant residues in Hippo feces. After sinking into the water, microorganisms flock to enjoy the delicious food. Microorganisms need to consume oxygen to decompose plants, and fish died due to hypoxia.

The reason for this tragedy is not only the large number of hippos, but also their excretion as wide as the sea.

When hippos shit, they will raise their hips, swing their tails and throw their shit everywhere, in order to mark their territory and swear sovereignty.

Therefore, it is not that the exhibition hall is not cleaned, but that the hippo is indeed a sloppy animal.

In order to ensure the water quality as much as possible and make hippos comfortable, we change the water once a day. It takes a lot of time to change the water alone. Each change of water is in tonnage.

When the water is drained and cleaned, several garbage cans can be cleaned out of the feces below. "

"Well, so it is! Misunderstood!"

"I remember when I went to the zoo when I was a child, I saw a hippo shit, lying in a trough! The spraying force! While spraying shit, I flapped my tail and covered the wall with shit."

"Ha ha, the picture has a strong sense!"

Fang ye took the pineapple from Lao Gang''s hand and said hello to Dudu: "Dudu?"

Dudu looked at Fang ye, but he had no resistance to him. His head stretched out from the water, opened his mouth and shook his ears.

While the blue carp is shooting, you can clearly see the whiskers on the hippo''s mouth and the thick teeth in his mouth.

Lao Gang shook his head helplessly.

He feeds and cleans conscientiously every day. When he is free, he comes to chat with hippos, feed and cultivate feelings. Dudu is also cruel to him.

The principal met so few times, but Dudu was very kind.

It''s a bit of a blow to people''s confidence.

Fang ye said with a smile, "Hey, you smell the fragrance, don''t you?"

Throw the pineapple into Dudu''s mouth!

Dudu closed his mouth, only heard a dull "click", his mouth moved twice, and the two fat meat around his mouth rolled.

Open your mouth again and the pineapple has become small pieces.
