    Why don't birds get lost on their long migratory (迁居的) flights? Scientists have

puzzled over this question for many years. Now they're beginning to fill in the blanks.

    Not long ago, experiments showed that birds rely on the sun to guide them during

daylight hours. But what about birds that fly mainly by night? Tests with artificial (人

造的) stars have proved conclusively that certain night-flying birds are able to follow

the stars in their long-distance flights.

    One such bird-a warbler (鸣禽)-had spent its lifetime in a cage and had never flown

under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The

bird's cage was placed under an artificial star-filled sky at migration time. The bird

tried to fly in the same direction as that taken by his outdoor cousins. Any change in

the direction of the make-be-live stars caused a change in the direction of his flight.

    Scientists think that warblers, when flying in daylight, use the sun for guidance.

But the stars are apparently their principal means of navigation (导航). What do they do

when the stars are hidden by clouds? Apparently, they find their way by such landmarks as

mountain ranges, coast lines, and river courses. But when it's too dark to see these, the

warblers circle helplessly, unable to get their direction.
