When cold weather is coming, some birds will hibernate. However, other birds will leave us to fly away to the warm places, leaving human beings to deal with the snow and ice. So the bird's migrations always puzzle many people, because birds don't have maps---so how do they know where they're going? And how do they get the energy to get there? Now look at following tips given by the researchers and you'll know the reasons.

　　How do they know where to go?

　　。Sighting the landscape features like rivers, coastlines, and mountain ranges.

　　。Flying by Earth's magnetic field, obviously with their visual system and with something called magnetite[磁铁矿] in their heads.

　　。Using the stars for guidance at night or if the weather is not sunny.

　　。Using the sense of smell.

　　。Probably with the help of their neighbors or experienced birds. It is observed that many birds migrate in large flocks, followed by their neighbors and experienced birds.

　　How do they get the energy to get to the destination?

　　。Flying slowly and steadily. This is the most basic way that birds use. Many other birds migrants keep beating their wings until they land during their long journey.

　　。Taking advantage of updrafts. Smarter birds know how to make full use of updrafts of air caused by solar heating, to take a free ride high into the sky.

　　。Flapping and gliding(moving in a smooth, effortless manner). These birds wave their wings for a few beats, and then glide for a while. After they lose some speed, they flat some more.

　　。Bounding (Leaping forward or upward). This is a combination of flapping and gliding.
