斑点鬣狗会咕哝咕哝叫,会吼叫,可是你知道吗?它们最有名的是笑声,是的,咯咯的笑声。


科学家发现,这种动物会用笑声作为语言来交流诸如年龄、身份和地位等信息,这样,就知道把猎获的肉中最美味的那一块给谁享用了。是不是很有趣?


Hyena 1 Laughter Is Serious Business


Spotted 2 hyenas 3 grunt 4 and growl 5. But you know what they're famous for. [Hyena sounds.] So what's all the laughing about?


Well, field researchers have noticed that groups of hyenas tend to giggle 6 around a kill, while they're waiting for their hunk of meat. Now a study in the journal BMC Ecology  says the chuckles 7 may communicate things like age, identity and social status. Which is important stuff for figuring out who gets the tastiest cut of zebra.


Researchers [Nicolas Mathevon et al.] studied a clan 8 of spotted hyenas living in a sanctuary 9 behind the U.C. Berkeley campus. They enticed 10 17 hungry hyenas with bones or pieces of meat, and recorded about 250 bouts 11 of giggling 12. Then they ran those sound bites through various computer algorithms, running statistical 13 analyses and drawing up spectrograms.


The result? They say a giggle's pitch and timbre 14 establish a hyena's identity, and that pitch indicates age. But the giggle also tells you who's boss. A relatively 15 monotone giggle [hyena sound] and you're first to the meat. A more erratic 16, variable giggle? [Hyena sound] Get back in line.


The researchers next plan to study hyenas in the wild. Just for laughs.
