The walls in the toilet are light and Warm Beige. The fan runs, and the smell is also very common.

The ground is very clean. It is obviously cleaned from time to time. The opaque frosted glass has natural light.

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

At Dongdong''s convenience, Dongdong''s mother saw some thin brochures on the wall and couldn''t help looking through one.

The booklet is the bird Atlas of the bird Museum, with pictures and names, without too detailed introduction.

After all, it''s a pamphlet that can be taken free of charge in the toilet. It''s too detailed. There are too many pages, which is also a lot of cost. It''s OK to identify birds according to the pictures.

There is also a simple popular science page behind the booklet: what should I do when I encounter nestling birds on the roadside?

"Spring is the breeding season for wild birds, and nestling chicks are very common.

In the process of growing up, chicks will first grow wings, feathers on their heads and bodies. After most of the feathers grow, they begin to grow tail feathers. At this time, the nest is very crowded for chicks! So when tail feathers grow, they need to leave the nest.

Young birds do not immediately have the ability to spread their wings and soar. They first leave the nest and hop and flutter to the nearby branches to familiarize themselves with the use of their wings. This process is also known as "flying out".

During the "flying out" period, the parent birds will continue to feed the chicks, and the chicks will not stay away from the nest. They just move on nearby branches and exercise their flying skills. After a period of time, when the chicks master the flying skills skillfully, they will follow their parents to travel north and South and learn more survival skills.

Young birds learning to fly sometimes fall into the grass because of their unskilled flying skills, but don''t worry. Generally, parent birds will still look after them nearby.

So, don''t rush to take the chicks home, or give them to the zoo or rescue center. They may not need help!

This is a young blackbird that has been squeezed out of its nest and its feathers are not fully developed. It really needs help!

These two ignorant looking barn owl cubs were picked up by citizens on the roadside and brought home. In fact, they are very healthy.

How to judge whether chicks need help?

[judgment flow chart]

Why can''t you take it home and feed it yourself?

Meanwhile, the men''s room on the other side!

It''s all here anyway. Let''s go to the last one.

Dongdong''s father is also going to the toilet. As soon as he came to the door of the toilet, he saw a very interesting scene.

A peacock is standing on the washstand in the bathroom. Its long skirt is usually decorated with beautiful tail feathers with many eyes, which has been dragged to the ground.

The head faces the mirror and looks at the bird in the mirror carefully. Then the head turns left and right and looks at it from different angles.

Although the tourists felt interesting and pointed to the peacock to talk, they didn''t bother the peacock and washed their hands in another pool next to it.

"How did the peacock fly to the toilet?"

Dongdong''s father thought it was fun and took a picture.

There''s no problem taking pictures outside. You can only take pictures of the wash basin.

Thought of a question: "does the peacock know that he is in the mirror? Or another peacock? "

Enter the toilet and find it very chic!

Pictures of various animals are pasted on the door of the compartment.

But it''s all ass to people.

The animal in the first pit looks like a deer. Its head turns around and its butt is white heart-shaped!

Dongdong''s father was stunned: "surprised, is this ass pretty good? What deer is this? "

Introduction: roe deer!

Roe deer''s ass not only looks beautiful, but also acts as a road sign for other companions. Prevent your companions from running away when you act together.

Dongdong''s father paced to the second pit. Anyway, he didn''t have to go to the bathroom.

The animals on the door of this compartment have pink, blue and purple buttocks, which are very bright!

Real rainbow fart!

"Shit, what animal''s ass is so fancy?"

Introduction: mandrill!

The capillaries on the monkey''s ass are rich, so it is red through the skin, while the blue on the mandrill is caused by the regular diffraction of light by the collagen fibers of the skin.

Mandrill''s face and butt are very bright. For mandrill, the brighter the color of these parts, the higher the status in the population and the easier it is to get the favor of females.

The panda pouts its ass and looks very cute.

Dongdong''s father was going to hush, but when he saw that a compartment door opened and something seemed to stick behind the door, he went in.

In front of the door is about ass, and behind the door is about shit!

Squatting on the toilet, he looked up with relish.

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

Dongdong''s father was surprised: "didn''t you pull someone out?"

The feces of many herbivores are granular!

Zebra feces are about 40 grains at a time, 12-13 times a day, the size of which is like broad beans.

Giraffe feces are about 80 grains at a time, 10-12 times a day. They are spherical, with a diameter of 3 cm and are unexpectedly small.

Koalas, that is, koalas, have about 40 feces at a time, 3-5 times a day, like melon seeds. They smell like Eucalyptus.

Pandas retain the characteristics of carnivores in their intestines and stomachs, and their digestion efficiency of bamboo is less than 20%. Undigested bamboo knots and leaves become "green groups" and are discharged. They not only do not smell, but also emit a faint fragrance of bamboo! Let people want to hear it soar.

Wombat POOP is very strange!

Chrysanthemum is not square, but the stool pulled out is the shape of a square, which is called convenience for short.

It turns out that this unique shape of stool is due to the unique structure of the large intestine. The intestine is in a quadrangular shape. When dehydrated, the stool is gradually square. The more dry the environment is, the more distinct the edges and corners of the stool are.

……

After going to the toilet, they meet outside!

Yingying''s father smiled and asked, "how about their toilet?"

Dongdong''s father still had something to say. He exclaimed with joy: "it''s really done well! There is science in this toilet. "

Dongdong''s mother asked curiously, "what popular science?"

Dongdong''s father said, "there''s an animal''s ass on the door of their compartment! Mandrill''s ass is actually blue purple red, especially bright. It introduces animal excrement! African elephants can pull 75-90 kilograms of excrement a day, panda excrement and the fragrance of bamboo. It''s really a long knowledge. Well, don''t you have a toilet? "

Dongdong''s mother shook her head: "no, but there are pamphlets!"

Third, the bathroom mainly serves children and the disabled, pays attention to functionality, and does not engage in those fancy.

He handed the booklet around to the public, looked at it and sighed, "it''s really a knowledge. If you don''t understand it, you may have a good intention to do bad things!"

Dongdong''s father remembered, "I picked up a chick on the lawn at my door when I was a child! Put it in a box. At that time, I thought it was hungry and caught all kinds of insects for it to eat. Now I think it may not be edible insects. Anyway, after feeding for a long time, I burp farts. "
