The next morning!

Liu Wei and his classmates had breakfast in the canteen and gathered at the school gate.

Seeing Jiang LAN and Yang Yue, the boys smiled and said, "our goddess is coming!"

"After a holiday, the goddess is still beautiful!"

Jiang LAN has no reaction. She is used to the exaggerated ridicule of the boys. Yang Yue covers her mouth and laughs!

As the sister of the software department, they are all spoiled by the boys.

The monitor was tall and thin, wearing a pair of glasses and asked, "has everyone come? Go, go! "

……

Get on the bus and come to the gate of the zoo.

In fact, if you don''t take a bus, you can walk for more than ten minutes.

The zoo and Xinghe university are still very close.

When Liu Wei bought a ticket, he found that the ticket price was only 30 and the student ID card had a half price discount!

A 15 yuan ticket costs about the same as a cup of milk tea.

He exclaimed, "Wow, the zoo tickets are so cheap!"

Wu jiancong thought it was normal: "the zoo tickets at my house are cheaper, 25 in the peak season and 20 in the off-season!"

Gao Kaijin seems to have some doubts: "I remember that the tickets to the wildlife park are very expensive! It may start at 100 yuan, or even two or three hundred. "

Liu Wei scratched his head: "what''s the difference between zoos and wildlife parks?"

This problem baffled both roommates. After thinking for a while, they didn''t understand.

In fact, wildlife parks are generally built in the suburbs, which can be larger and provide broader space for animals.

The disadvantage is that the transportation is inconvenient, the ticket price is more expensive, the commercial nature is stronger, and there may be animal performances.

Another meaning of wildlife park is that the environment is closer to the wild environment and the animal display is better.

Urban zoos are generally public welfare, so the ticket price is dozens of yuan.

In fact, the boundary between the two is not so clear. For example, Linhai zoo is located in the suburbs and has a wild name, but the area is not large and the ticket price is very cheap.

Although some wildlife parks have a large area, the environment is actually very bad, which is not as good as the display of urban zoos. Some City Zoos also have animal performances.

Anyway, this problem does not affect their visit to the zoo. If they don''t understand, the visit is over!

……

When I came to the square, I first saw a group of white pigeons on the green grass next to me!

Before, I set up a green net to keep pigeons in captivity, and sprinkled some feed on this grassland every day.

Now the net has been removed, and the pigeons are used to moving on this grass.

"Wow, a lot of pigeons!"

At this time, many tourists are in front of the fence on the grass, looking inside and looking curiously at it!

Liu Wei said, "to tell you the truth, it''s the first time I''ve seen a living pigeon! I''ve only seen it in soup before! "

Wu jiancong nodded deeply: "me too!"

Yang Yue looked around, saw the volunteers nearby, ran over and asked, "Hello, can you feed these pigeons? Is there a place to sell feed? "

The volunteer explained: "these square pigeons have just settled in the zoo and are not very familiar with the environment. They may fly away when they are fed. Therefore, there is no service in this regard at present, and there may be one in the future!"

Yang Yue was a little disappointed: "Oh, OK!"

Pigeons are pacing leisurely on the grass!

As domesticated poultry, pigeons are not too afraid of people.

A sparrow flew down from the treetop and jumped on the lawn looking for food!

Pigeons have regarded this lawn as their own territory. When they see sparrows flying over, several close ones immediately run towards the sparrows, flapping their wings and driving them away.

This is our territory! Go, go!

At the beginning, he ran quickly, chased for a few meters and flew at a low altitude.

Although the pigeons behind didn''t know what happened, they saw that some companions flew up and quickly followed the footsteps of the big army. Suddenly, more than 30 pigeons all flew up!

Flying together, the sound of "pop pop pop" wings became clear and audible. Dozens of pigeons flew past the tourists in front of them. It still looked very spectacular!

The tourists'' eyes moved with the pigeons, making a startling cry.

"Wow!"

"How beautiful!"

"How neat it flies! Have they been trained? "

Someone "KaKa" took photos.

If the little sparrow chased by the dove is able to speak, they will surely say: "I rely on what I have done, and I will make complaints about the anger of the people, so that you can make a division of the troops to catch up with me!"

The pigeons drove the sparrow away from this area, and the leader in front turned a corner and flew back smartly!

Hovering low on the lawn, vowing their sovereignty.

When he came back after flying around, Wu jiancong held out his hand and tried to slap the pigeon!

Of course the pigeon didn''t bird him. The line split into two parts and flew past on both sides of his raised arm.

Half circled twice and returned to the grass!

The other half flew to the nearby tree or landed on the ground of the square.

Yang Yue fell down beside her, stepped on her claws, explored her head, looked around and walked forward, as if she was a little nervous.

Yang Yue squatted on the ground and said excitedly to Jiang LAN: "Wow, this pigeon has fun walking!"

Jiang Lan was also full of interest. She hooked her fingers at the pigeon and said, "come here!"

The pigeon looked at her and quickly got in through the wide gap of the fence!

I joined up with the big army and came to the lawn. I looked at ease and slowed down.

Next to the lawn of the square, a new exhibition board was erected, and a bronze statue of a pigeon was placed in front.

When Liu Wei passed by, he took a curious look. There were two pictures on the exhibition board. In the first picture, a large group of birds were flying all over the world, like a large black cloud floating in the sky, and in the second picture, a pigeon standing alone on a branch.

The contrast is very obvious.

"There was once a miraculous bird.

If you go back to the early 19th century, you may see such a scene in the United States. A bird flying circle 1.6 kilometers wide and more than 500 kilometers long blocks the sky and the sun. It takes several days to cross a farm. This flock of birds is the North American traveler''s pigeon.

The famous ornithologist Audubon once predicted that this bird would never be extinct by mankind.

However, as a large number of birds with delicious meat, traveler pigeons ushered in large-scale commercial hunting in the 18th-19th century.

In the 1840s, the number of passenger pigeons has decreased significantly.

In the 1870s, it was difficult to find flocks of pigeons in the wild.

In 1900, a boy shot and killed the last wild pigeon with an air gun. Since then, no pigeon has been found in the wild.

The attempt to artificially breed passenger pigeons also ended in failure. On September 1, 1914, the last artificially bred passenger pigeon ''Martha'' also left the world.

Once a huge population with a population of 5 billion, it was completely extinct in just one and a half centuries.

Humans have erected a monument to the traveller pigeon, which reads "the species was extinct due to human greed and selfishness."
