Do you know why different animals or pests (昆虫) have their special colors? Colors in them seem to be used mainly to protect themselves.
  Some birds like eating locusts (蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of crops(庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters (猎人). This is because they have the colors much like the trees.
Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid (液体)when it faces danger. While the liquid spreads over (散开), its enemies (敌人)cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.

When I was a little girl, my family lives in a small village. There was a very beautiful river near my home. The water was clean and cool. I liked to go fishing there with mom. We would catch fish, look for clams and play in the water. There were also a lot of  birds near the river. We would spend all day watching the birds. Life was beautiful and wonderful in the old days.

Now my family lives in the city. Last Sunday my daughter asked me to take her to see the beautiful river I was always talking about. “I want to go fishing there with you and Grandma ao much,” she said.

When we went to the river, we only saw a factory and a mountain of garbage(垃圾). My mom was surprised, my daughter was quite despondent, and I was sad—the river was my best friend. I grew up with it. Now there are no fish in it; the birds are gone, too. I hear it crying for help. But what can I do ?

Zhalong is a nature reserve in Heilongjiang in north-east China. It is one of the world’s most important wetlands. The reserve covers an area of 210,000 hectares. The area provides food and shelter for wildlife. It is an ideal home for different kinds of plants, fish and birds.

Many birds live comfortably in Zhalong Nature Reserve all year round, while some only stay there for a short time. There are many fish in the wetlands, and the birds can easily catch them for food. Zhalong has long been called “the home of the crane”. There are 15 crane species (物种) in the world. 8 of them are in China and there are 6 species in Zhalong area. It is an important living area for the rare red-crowned cranes. There are not many red-crowned cranes in the world. Every spring and summer, red-crowned cranes lay and hatch (孵化) their eggs in Zhalong.

Some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife. More and more birds are in danger because they do not have enough living space. Many of them died. The Chinese government wants to protect these endangered birds, and they can be safe in Zhalong.

Every year, a lot of tourists go to Zhalong to watch birds. This year, members of our Bird-watching Club are going to study the different kinds of birds in Zhalong and the changes in their numbers. The study begins next month.

We _______ once a year. We are now inviting secondary school students to help. We need more people to help us count and do something to help the birds.

Many people do not understand the importance of the wetlands. We hope this information will help them understand and make them actively take action to protect wildlife.
