There are four toucans in the exhibition area!

There are two toucans standing on different treetops, listening to all kinds of birds chirping and whining outside. They don''t move. Occasionally, they turn their heads and look at each other. They seem to say that they can''t make a noise, but they''d better be a quiet beautiful man (woman)!

One jumped around on the trellis and flew around. After a while, he bit the leaves and looked very lively.

There is also a Toucan standing on a curved trunk in the stream - the stream is actually a one meter wide stream, which bends and falls from several simple earthy yellow rocks and splashes white water. It looks very ornamental.

On the back wall is also the wall painting painted by Zhuang Xiaobai. It is a light green forest with golden sunshine and shadow. The details are very in place. It is integrated with the streams and trees in the exhibition area and looks natural and harmonious.

The toucan was cleaning itself with water. Its blue claws scratched its huge orange beak quickly, scratched both the left and right sides, then raised its wings and combed the feathers under its black wings with its beak.

After combing, he jumped into the stream, splashed with his wings, wet his body, turned around and jumped back, and then flapped his wings and flew to the top of the tree.

Ying Ying was fascinated and then asked curiously, "Ma Ma, why are their mouths so big? How did you fly with such a big mouth? "

Liu Xueqing looks at an exhibition board next to her, on which is the picture of toucan''s big mouth. That''s what I''m talking about!

Toucan only stay inside. Of course, there will be no less display cards here.

Tourists who see the strange shape of Toucan, whether big friends or children, must have this doubt.

Liu Xueqing picked the simple and understandable content above and told Yingying: "the beak of Toucan is hollow! It''s actually very light. It''s not as heavy as it looks. "

The outer surface of the bird''s beak is a thin layer of cuticle, which is hollow and honeycomb like. The special structure can absorb the impact from outside.

Naturalists study why Toucan is so exaggerated and what its purpose is. They find that it plays a role similar to chopsticks.

Toucans are bulky and want to pick berries and seeds. If they stand at the end of thinner branches, the branches can''t bear their weight.

However, standing on the thicker branches with a big mouth, you can eat the fruit growing on the thin branches.

At ordinary times, I scrape my beak with my claws and rub it on the branches to remove the food residue and aging cuticle on the beak, so as to avoid excessive growth or bending of the beak due to lack of wear and affect the sensitivity of feeding.

Liu Xueqing''s eyes lit up when she thought of the behavior of cleaning her Toucan in the stream and rubbing her beak with her claws!

There is a feeling that when I do problems at school, I suddenly see a subtle solution that I didn''t think of.

At this time, the door on the back wall quietly opened a crack.

The breeder opened the door gently and looked in with his head, and the toucans turned their heads and looked over.

When they first came to the new environment, they were familiar with the exhibition area and the breeders. In particular, the toucan exhibition area had little space to avoid, so the breeders'' actions would be lighter and slower to let them know that they were harmless.

He took a food basket into the exhibition area and tied the grapes to the branches and perch with string!

Tie them separately and hang two or three on one branch.

Liu Xueqing suddenly had a doubt. Other animals just chew and swallow. The beak is so long and one-third of its length. How does it eat and swallow?

With doubts, he quickly reminded: "Yingying, look, toucan is going to eat!"

When the breeder left, he saw a bold Toucan first relax his vigilance and fly to the perch.

Standing in the middle of the perch, he observed the food. His body suddenly tilted forward, leaned over his body to probe his mouth, grabbed a grape with the tip of his beak and picked it smoothly!

Then put the grape under your feet, fix it, clamp it with your beak and bite it off half.

The tourists stared with wide eyes.

Something unexpected happened!

The toucan suddenly raised its mouth and threw the grapes into the air with a clever force. Then his head tilted up and opened his mouth, and the grapes fell into his mouth accurately.

The action is done at one go, handsome and smooth!

The tourists were stunned: "sleeping trough! Handsome! "

"Good guy, eating is like acrobatics!"

"I also played this with my classmates! Throw snacks into the sky to see who can pick them up. But I''m stupid. I can''t usually get it. "

Liu Xueqing finally understood how Toucan eat with such a long mouth!

Yingying keeps her eyes on her and is so happy that she claps her hands.

After watching Toucan eat, go on.

Here comes the rhinoceros exhibition area!

Rhinoceros and Toucan also have huge beaks, which are often confused by tourists.

"Ma Ma, what bird is this?"

Liu Xueqing took a look at the exhibition card: "this is a horned hornbill!"

The adult bird of the double horned hornbill has a large mouth of 30cm and a large and wide helmet protrusion. The helmet protrusion is slightly concave, and there are two horn protrusions on the front edge, which looks like the helmet of an ancient warrior, so it is named double horned hornbill!

It is much larger than Toucan, with a wingspan of 140-160cm. It is a large bird, and the exhibition space is much larger than Toucan.

At this time, two rhinoceros stood on the perch, and the keeper explained to the tourists: "on the left is the rhinoceros wife, named Tian Tian, and on the right is the rhinoceros husband, Feifei!"

It seemed that she had just replenished food. She picked up a nut from the container hanging on the perch, leaned her head to the right and stuffed it into Feifei''s mouth. Honey, here you are!

Feifei took the nut in his mouth. The tips of the two hornbills touched the tips of their mouths. Then Tiantian loosened his mouth. Feifei blinked at Tiantian and handed the nut to Tiantian. Honey, you''d better eat!

The tourists, especially the single youth, were very sad: "lying in the trough! I was loved by the bird show! "

"These days, when you visit a wolf house, you will be fed dog food, and when you visit a bird house, you will be fed bird food! It''s too hard for me! "

"Sour, sour!"

"What did I do wrong? Let me see this!"

Tiantian bumped twice in her mouth and stuffed it into Feifei again!

When Feifei handed it back this time, Tiantian''s mouth was not clamped firmly, and the nuts fell down.

When the keeper saw it, he couldn''t help but "puff" and laughed: "you can see that our hornbill couple really love each other! They are reluctant to eat delicious nuts and are feeding each other. "

Two hornbills looked at each other, Feifei took another one out of the container and fed it to Tiantian. Tiantian ate it this time.
