Although the singing on the radio stopped, netizens were still immersed in sadness and emotion for a long time, reminiscing about the beautiful dance of the red-crowned crane just now.

Some people even opened the player without getting enough of it, searched for this song, and listened to it carefully.

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

After a while, my mood eased a little and I asked, "How is it, is it different from the feeling I felt when I listened to this song as a child?" ”

"Well, when I was a kid, I was scared when I heard this song! I felt that the girl had died a pitiful death, and now I can understand the emotions 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 red-crowned cranes to the wintering grounds to breed may have scientific research value, but from the perspective of nature conservation, it needs to be treated rigorously."

The domestication of red-crowned cranes has changed the habits of red-crowned cranes, and the red-crowned cranes bred in the reserve still face many difficulties in releasing them, which is different from the real wild red-crowned cranes.

Will the captive-bred red-crowned cranes return to the wild population, will they be infected with diseases? Will it change the habits of wild red-crowned cranes?

According to the statistics of the previous two years, the population of wild red-crowned cranes in China is only 500, which has always been an endangered state, but the captive population has reached 2,500, and there is no record of large-scale successful rewilding of red-crowned cranes.

There are also some commercial air shows of red-crowned cranes in captivity in the reserve, taking eggs from the nest of red-crowned cranes in the wild, and finally selling them to zoos, called conservation, which are actually profitable, are all problems.

Red-crowned cranes in the wild are very vigilant and may abandon their nests if someone enters their territory.

Even if they pick up the eggs, they will make up for the eggs, the hatching time of the cranes will be delayed, the feathers will not grow and cannot migrate, and the red-crowned cranes will stay in the northeast with their children and cannot overwinter, which is also the reason why the wild red-crowned crane population has not been able to grow. ”

"Huh? So angry! ”

"It's unacceptable! How can you treat them like that? ”

"Principal, did you buy your cranes from the reserve?"

Fang Ye explained: "Our red-crowned cranes were introduced from other zoos. In fact, the first animals in the zoo were caught from the wild, but it is not appropriate to do such a thing now. You can understand this, right? ”

"Understand! If I had thought that zoos shouldn't exist. But after watching the director's live broadcast, I realized what a really good zoo looks like. ”

"Yes, zoos are not only places for entertainment, but also for education."

Fang Ye said: "Therefore, it is the best expression of love to really love red-crowned cranes and protect their habitats."

Let's go, and see our new hippos and giraffes. ”

……

Come to the back house of the hippo house.

The back house of the hippopotamus is different from other houses, because the hippopotamus needs water to live, so in addition to the normal animal house, there is also a small pool in the next room.

However, the pool looks dirty and not very clear.

There were some grass blade residues floating on the water, and some ball-shaped things could be faintly seen at the bottom of the water, which looked like and eggs.

The keeper is an uncle in his forties, who will hold a pineapple in his hand, and a bucket in the other hand, through the railing, and call the name of the hippopotamus with a smile: "Dudu? Doodle? ”

Dudu's huge dark brown body was mostly submerged in water, and its back, nose, and eyes were exposed.

The little eyes looked at Lao Gang, and suddenly his head flicked, slapped the water, and made a loud "whoosh" sound! It's like a cannon shot in the water.

A splash of water was lifted, and although Lao Gang was some distance away, there were still some small droplets of water thrown on his face.

Fang Ye and Lan Carp saw this scene as soon as they came over, and Lan Carp was startled by this loud movement, and hurriedly hid behind Fang Ye and looked out cautiously.

Lao Gang looked used to it, wiped the water droplets on his face, stood up, and greeted Fang Ye: "The head of the garden is here!" Eh, Dudu doesn't seem to like me very much! ”

At this time, Dudu's nostrils sprayed again, and a mist of water erupted, as if to express his dissatisfaction.

Fang Ye smiled: "Dudu is a more timid character." ”

Some netizens wondered: "This environment looks a little dirty, don't you clean it?" ”

"yes, the water is so muddy! Hurry up with your shifts. ”

"With such dirty water, of course the hippopotamus is not happy."

Fang Ye glanced at the barrage and said, "I don't know if you have seen the news that a large number of dead fish with their bellies turned on the edge of the African River appeared, and the investigation found that they were smoked to death by river?"

It sounds a bit outrageous, but it's true!

The claim of fumigation is a bit exaggerated, to be precise, the fish died because of lack of oxygen. The hippopotamus has a large amount of undecomposed plant residue in its feces, and after sinking into the water, microorganisms rush up to enjoy the delicious food, and the microorganisms need to consume oxygen to decompose the plants, and the fish die of lack of oxygen.

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

When the river horse shit, he will also cock his buttocks, flick his tail, and throw shit everywhere, in order to mark the territory and swear sovereignty.

So it's not that the pavilion isn't cleaned, it's that the hippopotamus is indeed a sloppy animal.

In order to ensure the water quality as much as possible and make the hippopotamus stay comfortable, we change the water once a day, and it takes a lot of time just to change the water, and each water change is measured in tonnage.

When the water is drained and cleaned, the feces underneath can be cleared out of several garbage cans. ”

"Well, I see! Misunderstanding! ”

"I remember when I was a kid when I went to the zoo and saw a river,! The power of the jet! Squirting and flicking his tail while pasting the walls all over the. ”

"Haha, the picture is very strong!"

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

Dudu glanced at Fang Ye, but he didn't have any resistance to him, his head sticking out of the water, his mouth wide open, and his ears twitched.

The blue carp was filmed on the side, and you could clearly see the whiskers on the hippopotamus's mouth, as well as the thick teeth in its mouth.

Seeing this, Lao Gang shook his head helplessly.

He fed and cleaned diligently every day, and when he had time, he came over to chat with the hippopotamus and feed to cultivate feelings, and Dudu murdered him.

The principal met so few times, but Dudu behaved very kindly.

It's a bit of a blow to confidence.

Fang Ye smiled: "Eh, you smell the fragrance, right?" ”

Throw the pineapple into Dudo's mouth!

Dudu closed his mouth, only to hear a muffled "click", his mouth moved twice, and the two fat flesh on the side of his mouth also rolled.

When I opened my mouth again, the pineapple had already turned into small pieces.
