最近德国科学家发现,鸟类利用右眼查看地球磁场,并依此导航。如果用眼罩把小鸟的右眼罩住,它们就无法有效导航;它们的左眼被罩住,仍能非常完美地导航。鸟类能感觉到地球磁场,并利用它们导航,尤其当鸟类为了过冬,向南方迁徙时。鸟类能用右眼看到磁场,并把信息传递给左脑。磁力图产生的明、暗阴影,鸟类利用它们的正常视觉就能看到。 Recently German scientists found that birds use the right eye to see the Earth's magnetic field and navigate accordingly. If the bird's eye is used to cover the right eye of the bird, they can not be effectively navigated; their left eye is covered and still perfectly navigate. Birds can sense the Earth's magnetic field and use them to navigate, especially when birds migrate to the South in order to winters. Birds can see the magnetic field with the right eye and pass the information to the left brain. The bright and dark shadows produced by magnetic maps can be seen by birds using their normal vision.
