"How does one account for such migrations? Why do birds migrate at all? How do they know when it’s time to begin the long journey? What guides their flight path and direction? How do they know their destination, and how do they prepare for the trip? These and other questions have occupied research of scientists for years. Some questions have brought clear answers; others are still being searched out. For a scientist committed to the Christian worldview, the migration of birds is another instance revealing that there is a divine design behind all such wonders of nature."
