一项对鸣鸟解决问题能力的测试揭示了交通噪音是如何损害这些动物的能力的。科学家们给珍珠鸟设计了一组 “觅食任务”，分别在有噪音和无噪音的环境下进行。
Rather than studying birds in the wild, these researchers brought recordings1 of traffic noise from the nearby road into their lab and put captive zebra finches to the test.
这些研究人员并没有在野外研究鸟类，而是将在附近道路上录好的交通噪音带进他们的实验室，并对圈养的珍珠鸟进行测试。
The scientists designed tasks to mimic2 the problem-solving the birds have to do to find food – flipping3 over leaf-like lids to reveal a treat and working out how to reach a food reward that's hidden inside a cylinder4.
科学家们设计了一些任务来模拟鸟儿觅食时必须解决的问题。例如，翻开叶子状的盖子发现食物，并想办法获得藏在圆筒中的食物奖励。
In a quiet laboratory, birds were twice as likely to succeed, and to find the food, than when traffic recordings were being played.
在一个安静的实验室里，鸟儿成功找到食物的可能性是播放交通噪音录音时的两倍。
The discovery adds to mounting evidence that the sound we put into the environment has unexpected negative impacts on wildlife.
这一发现进一步证明，人为噪音对野生动物产生了意想不到的负面影响。
Studies have shown that noise can affect insect behaviour
