Spotted1 hyenas2 grunt3 and growl4. 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 giggle5 around a kill, while they're waiting for their hunk of meat. Now a study in the journal BMC Ecology says the chuckles6 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 clan7 of spotted hyenas living in a sanctuary8 behind the U.C. Berkeley campus. They enticed9 17 hungry hyenas with bones or pieces of meat, and recorded about 250 bouts10 of giggling11. Then they ran those sound bites through various computer algorithms, running statistical12 analyses and drawing up spectrograms.

 The result? They say a giggle's pitch and timbre13 establish a hyena's identity, and that pitch indicates age. But the giggle also tells you who is boss. A relatively14 monotone giggle and you're first to the meat. A more erratic15, variable giggle? Get back in line.

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

 —Christopher Intagliata
