Canada geese（鹅） are large, blue and white birds. When autumn comes, they fly to the south where the weather is warmer. Winter in Canada is very cold. The birds will die if they stay there. 

Last spring, Bill found sixteen young Canada geese on his farm. They couldn't find their parents. Bill had a small plane and he decided to teach the birds how to fly. All through the summer, Bill went on short trips in his plane and the young geese flew after him.

When the cold weather came, Bill flew to Virginia in the United States. The geese followed him all the way. Bill left the geese in Virginia and returned home. 

This spring Bill waited for the birds to come back. But they didn't. Bill flew to Virginia to get them back. He looked for them for two weeks but he couldn't find them. But when he arrived home, he found the geese were waiting for him. They could find their way home by themselves!
