In the 1950s, scientists caught a shearwater (剪水鹱) on an island off the coast of Wales. They took it to the city of Boston, and set it free. Twelve days later it was back in Wales. Many birds share this gift for finding their way.

Most migrating (迁徙的) birds fly between cold and warm places, partly to avoid the winter. Their trips are tiring and dangerous-fewer than half of first-time migrating birds make it back the next year. Small birds often fly at night, so they must stay over land and travel by day.

Some migrating birds seem to be born with a map that tells them where to go. Cuckoos,for example, can find the way without being shown. Other birds learn the way by following a group of birds and remembering landmarks, such as mountains and rivers. Landmarks based on smell and sound-such as the smell of a pine forest or the sound of crashing waves-may also help.

Experiments with homing pigeons tell us that some birds have a built-in magnetic compass (磁罗盘). This helps pigeons to find the way home from hundreds of miles away. But when tiny magnets (磁铁) are tied to their heads, they get lost.

Birds that migrate by day use the sun as a compass. They also have a built-in clock, to make up for the sun’s movement across the sky as the day goes. Snow geese migrate by the sun; when days grow longer, they become unable to stay quiet and want to set off on the long journey.
