Despite a common belief that giraffes' long necks could preclude them being able to vocalize, biologists have discovered that giraffes are indeed capable of humming.

尽管人们普遍认为长颈鹿长长的脖子限制了他们发声的能力,但生物学家发现,长颈鹿实际上可以发出哼哼声。

Researchers from University of Vienna analyzed thousands of hours of audio recordings taken at three different European zoos, taking note for the first time of a low-frequency hum coming from the giraffe enclosures at night.

来自维也纳大学的科学家们研究了录取自欧洲三家不同的动物园的长颈鹿的几千个小时的录音后,首次在项圈中记录下了长颈鹿在晚上发出的一段低频率的哼声。


Unfortunately, the recordings are audio-only, so researchers aren't yet sure what physical activities correspond to the humming -- it's even possible that the humming may not be an active process.

遗憾的是,这些录音都只有音频,因此科学家们至今无法确定这种哼声与什么生理活动有关——它甚至可能并不是某种生理活动。

"It could be passively produced - like snoring - or produced during a dream-like state - like humans talking or dogs barking in their sleep," Franklin & Marshall College's Meredith Bashaw told New Scientist.

来自马歇尔学院的Meredith Bashaw告诉《新科学家》杂志说:“这种哼声有可能是不经意发出的——就像鼾声——或者是在类似做梦的状态发出的,就像人们会说梦话,狗在睡觉的时候会吠。”

If it turns out that the hums are consciously produced, however, they could help researchers better understand how giraffes communicate within their highly structured societies.

如果事实证明这种哼声是有意识发出的,那么这些哼声就能帮助科学家们更加深入地了解长颈鹿如何在他们高度规范化的群体中进行交流了。
