小结：

The passage mainly tell us that birds don't migrate in a straight line.

As we know, birds migrate because of the changes of seasons.A bird migration expert and his team marked the movements of birds.

Do you know the "track" in Chinese? Let me tell you. The Chinese meaning of “track ”is 追踪.When the expect tracks the

movements of the birds over thousandsof miles.

They are very surprised that birds are born with an in-built sense of direction.So the birds migrate on  a round-route that is based on food supply.That means the birds try to find food on the way.
