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 become too crowded．They move down to the low land．Sometimes they move all the way the seaside，and many of them are killed when they fall into the sea．
