We know that many animals do not stay in one place. Birds, fish and other animals move from one place to another at a certain time. They move for different reasons most of them move to find food more easily, but others move to get away from places that are too crowded. When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration(迁移)is probably the migration of the fish, which is called “salmon”. This fish is born in fresh water but it travels many miles to salt water. There it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies there. In northern Europe, there is a kind of mice. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea.

    Recently, scientists have studied the migration of a kind of lobsters(龙虾). Every year, when the season of bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody knows where they go. So, sometimes we know why humans and animals move from one place to another, but at other times we don’t. Maybe living things just like to travel.

Research shows that humans switch from selfish to unselfish behaviors when they are watched. Do you?

A picture of a set of eyes on a computer screen can cause a change in the way people act. Even images of eyes on a charity donation, collection box encourage people to be unselfish, because people put more money in a collection box that has a picture of eyes on it than they do when a flower symbol is on the box.

 
Manfred Milinski from the Max-Planck Institute for Evolutionary

Biology in Germany and Bettina Rockenbach of the University of Berlin,

the authors of a new study, found that people act better when they are being

watched because they feel they will be rewarded for good behaviour.

Their report also referred to other research showing that this response of

behaving well when watched is somehow coded into humans and

people respond this way unconsciously, or without realising it.

It is not just humans that act unselfishly when they are being watched.

A fish called the grooming fish cleans other fish. When other fish are

around, it is gentler. When no other fish are around, however, the grooming fish bites chunks from the fish it is supposed to be cleaning.

The researchers suggest that the best way to get people to behave in the correct way is to make them feel watched. This could be the reason for the success of a famous American army poster. On it was a picture of an elderly man staring fiercely and pointing, it appeared, to the person who was looking at the poster. Under the picture was the caption ‘I Want You’. It encouraged hundreds of thousands of young American men to join the army during the Second World War to fight the Germans and Japanese.
