Homing pigeons can be 36 hundreds of miles from their homes. When they are let to go to 37 again, they find their way home. Because of this special ability to 38 ,pigeons have been used 39 messengers for hundreds of years. Today people even breed homing pigeons for 40 at a sport. The birds are shipped to some chosen 41 a few hundred miles away. Then all of them are let to go together. The winner is the bird that gets home 42 .A good race can make it home from 500 miles away 43 a single day. The mystery of the homing pigeons is how they 44 directions and how they find home. The first part seems to be pretty well 45 ,and we know of two ways that pigeons tell directions. First, they use the sun. Experiments show that homing pigeons can tell 46 by the sun. What happens when the 47 is darkly overcoat by clouds and no one can 48 where the sun is? Then the pigeons still find their way home. Naturally, people have wondered whether pigeons might have a built-in compass 49 that would tell them about the direction of the 50 magnetic(磁的)field. Many different kinds of experiments were 51 .Here’s what the scientists decided 52 they had made experiments many times. When pigeons can see the sun, they use it as their 53 means of direction-finding. When they can’t see the sun, they use some 54 way to sense direction from the earth’s magnetic field. (责任编辑：admin) |
