The fairy wrens trained with the thornbill's cry, fled when they heard it.

仙女鹪鹩用刺鸟的叫声训练，听到叫声就逃跑了。

The scientists first played the birds two recorded sounds that they likely had never heard before. One was a warning cry of an allopatric chestnut-rumped thornbill, a bird not native to Australia. The other was a computer-generated bird sound called " buzz" .

科学家首先向鸟儿播放了两种它们以前从未听过的录音。一种录音是异域的栗尾刺嘴莺的警告声，这种鸟不是澳大利亚本土的。另一种录音是电脑生成的" 嗡嗡" 鸟叫声。
