Why do birds travel such long distances every year? What route do they take and where do they fly through to reach their destination? Are the routes the same in spring and autumn? Why are the destinations and migration routes different for various birds? How do birds find their way and successfully reach their destinations? These are some of the questions that arise about bird migration, which stirs much excitement and curiosity within us. While the study of bird migration has a long history, we have only begun to unravel details of bird migration relatively recently. Today, we know the answer to many of these questions, but only for those birds where research has made significant progress.

In the first place, why do they migrate?
The author, who performed the satellite tracking of the migratory birds for many years on the stage of Southeast Asia, Siberia, Central Asia, shows many interesting episodes concerning the migratory birds, especially Oriental Honey-buzzard coming and going 20,000 kilometers that are amazing results of research. This is a worth book reading.
