Every year, herds of animals in Africa, such as the wildebeest, zebra and antelope, travel vast distances,eating the grass of the plains as they go, and return by the same routes. The buffalo used to do the same thing in North America before the great herds were wiped out. In the north of Canada, caribou and reindeer move south in the winter to escape the worse of the snow and ice.
There are great yearly movements of birds, too. In the autumn many of our birds fly away to warmer lands, some of them flying more than four thousand miles. At the same time, from colder parts of the world, such as the Arctic regions, birds fly into Europe to spend the winter.
Another kind of migration is that of the salmon and the eel. The salmon, hatched in a stream in Scotland, will make his way to the open sea and live there for several years. When it becomes adult, it will swim back to the very stream where it was born to lay its eggs. Eels are hatched in the Sargasso Sea, a strange seaweed- tangled stretch of water off the American coast. From there they migrate to the coasts their parents came from, and swim up rivers to live in fresh water for from five to fifteen years. Then they return across the Atlantic to the Sargasso Sea to lay their eggs, and when this is done they die. Nobody knows why the salmon and the eel undertake such long and dangerous journeys to lay their eggs in a particular place when many others, it seems would do just as well.
