Migration is the reason why so many people spend so much time watching birds. Without migration, nothing 'unusual' would ever turn up, and the pursuit would lose much of its appeal.
The pages in this section explore the big questions that come to mind when people think about migratory birds: Why do they do migrate? How did migration arise? Why do migratory birds go where they go?
The presentation is intended to be comprehensible, if challenging, to readers with no more than a basic formal education in biology. |
