超声波

But there are vocal mimics too, like a palatable species of tiger moth that deters bats by parodying the ultrasonic clicks of a toxic moth the bats detest, or like the greater racket-tailed drongo of Sri Lanka, which mimics the calls of other birds to drum up a mixed-species flock in which the drongos can more safely and efficiently forage.

但是也有针对声音的欺骗术，比如有一种自身美味无比的灯蛾会很搞笑地模仿一种令蝙蝠厌恶的毒性飞蛾的超声波频率，藉此逃避被吞吃的命运；还有一种长着像火箭似的尾巴的伊斯兰卡燕卷尾（反正是一种鸟，我以前没听到过，长相如何请参见wiki，点这里。
