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. In northern Europe, there is a kind of mouse. They leave their mountain homes when they bccome too crowded. They move down to the low land. Sometimes they move all the way the seadide,and many of them are killed when they fall into the sea.[来源:Zxxk.Com]

Recently, scientists have studied the migration of kind of lobster(龙虾).Every year, when the season of the 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 know where they go.[来源:Z。xx。k.Com]

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.
