Light pollution dampens urban robins' song

城市光污染抑制知更鸟的鸣唱

Robins are up and about earlier than most other songbirds, and they are in almost every city park in the UK, making them ideal for this urban study.

知更鸟早上醒来的时间比大多数鸣禽都要早,而几乎英国的每个城市公园都有它们的身影,这使得知更鸟成为这项城市研究的理想对象。

The scientists used a stuffed robin and a recording of the bird's song, setting up this fake avian intruder in different areas. They then measured each bird's response, recording how much it sang and displayed to defend its territory. This helped them construct a dominance hierarchy of the park's resident robins. Birds that lived closest to street-lit paths and to busy roads were much lower in this hierarchy. They were less vocal and aggressive.

科学家们用一只用填充物做的知更鸟并装有知更鸟叫声的录音,并将这个假的知更鸟防止在不同的区域。然后,他们测量了每只鸟的反应,记录了它们为保护自己的领地而歌唱了多少次,表演了多少次。这帮助他们建立了公园知更鸟的支配等级。生活在街道灯光和繁忙道路附近的鸟类在这个等级中要低得多。它们唱歌较少,也不那么好斗。

The researchers now want to establish if night-time light and man-made noise affects birds' abilities to forage or breed. They hope the findings might be built into urban planning to make city parks spaces designed for wildlife as well as for people.

研究人员现在想确定夜间光线和人为噪音是否会影响鸟类觅食和繁殖的能力。他们希望这一发现可以应用到城市规划中,让城市公园空间既能满足人类的需要,也能满足野生动物的生存需要。
