do pigeons take a train???

Pigeons are smart birds. They are good at finding places. They can find their way home from many miles away. Scientists are not sure how pigeons know their way, but they do. They almost never get lost. Can pigeons find their way under the ground?? Some underground passengers in tokyo say that they see pigeons on the underground trains. And they know where they will leave the train.

Why do the pigeons get on the trains? some people say that the pigeons are not looking for food. Tokyo is a big city, the pigeons are tired of flying and they do what people do. They take the train. What do the scientist think of this??? they say they must have some more information- but anything is possible with pigeons...
