Radar tracking of individual migrating birds flying over a large alternating-current antenna system showed that the birds turned or changed altitude more frequently when the antenna system was operating than when it was not. These results suggest that birds sense low-intensity alternating-current electromagnetic fields during nocturnal migratory flight.
对飞越大型交流天线系统的个体候鸟进行雷达跟踪显示，与天线系统未运行时相比，在其运行时鸟类转向或改变高度的频率更高。这些结果表明，鸟类在夜间迁徙飞行过程中能够感知低强度的交流电磁场。
