The walls in the toilet are a faint and warm beige. The fan is running, and the smell is normal.

The floors are very clean, apparently cleaned from time to time, and the opaque frosted glass lets in natural light.

The clean and bright environment makes people's spirits relax involuntarily.

When it was convenient for Dongdong, Dongdong's mother saw some thin booklets on the wall, so she couldn't help but take a copy and look at it.

The booklet is an illustrated book of birds in the bird house, with pictures and names, without too much detail.

After all, it is a booklet that can be taken for free in the toilet, and it is too detailed to make a detailed introduction, and the number of pages is too much, which is also a large cost, and you can recognize the birds according to the pictures.

There is also a page of simple science at the back of the booklet: What should I do if I encounter a nesting chick on the side of the road?

"Spring is the breeding season for wild birds, and nesting chicks are a common occurrence.

In the process of growing up, the chicks will first grow wings, feathers on their heads and bodies, and most of the feathers will only begin to grow tail feathers after they have grown, and the nest will be very crowded for the chicks! So when the tail feathers grow, that's when they need to leave the nest.

Chicks do not immediately have the ability to spread their wings and soar, they will first leave the nest and flutter to the branch next to the tree to familiarize themselves with the use of their wings, a process also known as 'flying'.

During the 'flight' period, the parent birds continue to feed the chicks, and the chicks do not stay away from the nest, but only move around the nearby branches and practice their flying skills. After a period of time, the chicks have mastered the flying skills and will follow the parent bird to the north and south to learn more survival skills.

Chicks who learn to fly sometimes fall into the grass due to their unskilled flying skills, but don't worry, the parent birds will still look after them nearby.

So, don't rush to bring the chicks home or hand them over to the zoo or rescue center, they may not need to be rescued!

This is a blackbird cub that has been squeezed out of the nest and its feathers are not fully developed, and it really needs help!

These two bewildered-looking barn owl cubs were picked up by the citizens on the side of the road and brought home, but they were actually very healthy.

How can you tell if a chick needs to be rescued?

【Judgment Flow Chart】

Why can't I take it home and feed it myself?

……”

At the same time, the men's toilet on the other side!

Anyway, it's all here, so let's go to the last one.

Dongdong's father was also about to go to the toilet, and as soon as he came to the door of the toilet, he saw a very interesting scene.

A peacock stands on the bathroom sink, its long skirt adorned with many beautiful tail feathers dragged to the floor.

Face your head in the mirror, look at the bird in the mirror, then turn your head left and right, looking at it from different angles.

Although the tourists found it amusing, they pointed to the peacock and said a few words, but they did not disturb the peacock and washed their hands in another pool next to it.

"How did the peacock fly to the toilet?"

Dongdong's dad thought it was funny and took a photo.

There is nothing wrong with taking pictures outside, only the sink.

A question comes to mind: "Does this peacock know that it is himself in the mirror?" Or is it something else? ”

When I entered the toilet, I found that the inside of the toilet was very chic!

On the door of the compartment, pictures of various animals are pasted.

But it's all butt to people.

The animal in the first pit looks like a deer, with its head turned around and its butt in the shape of a white heart!

Dongdong's father was stunned: "Surprised, this ass is quite good-looking?" What kind of deer is this? ”

Introducing: Roe deer!

The roe deer's butt is not only beautiful to look at, but also serves as a signpost for other companions. Prevent companions from running away when moving together.

Dongdong's father paced to the second pit again, anyway, he was not in a hurry to go to the toilet.

The animal on the door of this compartment has a powdery blue and purple buttocks, and the color is very bright!

What a rainbow fart!

"Holy shit, what animal's ass is so fancy?"

Introducing: Mandrill!

The monkey's buttocks are rich in capillaries, so they have a red color through the skin, while the blue color of mandrills is caused by the regular diffraction of light by the collagen fibers of the skin.

The mandrill's face and buttocks are brightly colored, and for the mandrill, the brighter the color of these parts, the higher the status in the population and the easier it is to be favored by females.

The panda pouted and looked very cute.

Dongdong Dad was about to shush, but when he saw that the door of a compartment was open, and there seemed to be something posted behind the door, he walked in.

It's about the ass in front of the door, and it's about shit behind the door!

Squatting on the toilet, I looked at it with relish.

Elephants have a lot of dung, African elephants excrete 10 times a day, and at a time they can excrete 5-6 pieces of cylindrical feces with a diameter and height of 20 cm, and one piece of feces weighs about 1.5 kg! An elephant can excrete 75-90 kg of feces in a day.

Dongdong's father was shocked: "Isn't this pulling someone out?" ”

The feces of many herbivores are granular!

Zebra droppings are about 40 grains at a time, 12-13 times a day, and the size is like a broad bean.

The giraffe feces are about 80 grains at a time, 10-12 times a day, and are spherical in shape, with a diameter of 3 cm, which is surprisingly small.

Koalas, also known as koalas, have about 40 droppings at a time, 3-5 times a day, like melon seeds, and smell like eucalyptus.

Because the panda retains the characteristics of carnivores, the digestion efficiency of bamboo is less than 20%, and the undigested bamboo leaves become "Qingtuan" discharged, which not only does not smell, but also exudes a faint fragrance of bamboo! Let people want to hear it.

Wombat's feces are very peculiar!

Chrysanthemums are not square, but the poop that is pulled out is the shape of a square, which is referred to as convenient.

It turns out that this unique shape of the poop is because of the unique structure of the large intestine, the intestine is in a quadrangular shape, and the poop gradually squares when it is dehydrated, and the drier the environment, the more sharp the edges and corners of the poop.

……

After everyone went to the toilet, they met outside!

Yingying's father smiled and asked, "How is it, is their toilet quite interesting." ”

Dongdong's father still looked a little unsatisfied, and praised happily: "It's really done a good job!" This toilet is full of popular science. ”

Dongdong's mother asked curiously: "What popular science?" ”

Dongdong's dad said: "They have an animal's butt on the door of their cubicle!" The mandrill's butt turned out to be blue-purple-red, which was particularly bright, and inside was the content of animal feces! African elephants can pull 75-90 kilograms of feces a day, and panda feces and the fragrance of bamboo are really a long knowledge. Eh, don't you have a toilet? ”

Dongdong's mother shook her head: "No, but there is a booklet!" ”

The third bathroom is mainly for children and the disabled, focusing on functionality and not engaging in those bells and whistles.

I circulated the booklet to everyone and looked at it, and sighed: "It's really a subject of knowledge, if you don't understand it, you may do bad things with good intentions!" ”

Dongdong's father remembered: "When I was a child, I picked up a chick on the lawn in front of my house!" Put it in a box, I thought it was hungry at the time, and I caught all kinds of bugs for it to eat, but now I think about it, it's not necessarily an edible bug, anyway, it burps after feeding it for a long time. ”
