Spotted 1 hyenas 2 grunt 3 and growl 4. But you know what they're famous for. So what's all the laughing about?


Well, field researchers have noticed that groups of hyenas tend to giggle 5 around a kill, while they're waiting for their hunk of meat. Now a study in the journal BMC Ecology says the chuckles 6 may communicate things like age, identity and social status. Which is important stuff for figuring out who gets the tastiest cut of zebra.


 Researchers studied a clan 7 of spotted hyenas living in a sanctuary 8 behind the U.C. Berkeley campus. They enticed 9 17 hungry hyenas with bones or pieces of meat, and recorded about 250 bouts 10 of giggling 11. Then they ran those sound bites through various computer algorithms, running statistical 12 analyses and drawing up spectrograms.


 The result? They say a giggle's pitch and timbre 13 establish a hyena's identity, and that pitch indicates age. But the giggle also tells you who is boss. A relatively 14 monotone giggle and you're first to the meat. A more erratic 15, variable giggle? Get back in line.


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


 —Christopher Intagliata
