This is scientific Americans 60 second science. I'm Karen Hopkins. This will just take a minute.

Everybody loves chimps, especially their endearing entreaties.

Scientists too love to listen to chimes. especially their endearing entreaties.

Scientists too love to listen to chimp's chat.

And they enjoy sharing these colorful commentaries with their colleagues.

Now, anyone with a hankering for primate prattle can listen in because researchers from the Netherlands have made available online a digitized catalog of more than 10

hours worth of chimpanzee calls.

The recordings are described in a new journal, published by nature,

called Scientific Data.

The audio, which includes more than a thousand separate data files,

was captured in the early 1970s by the late

heady font a right ploy. She recorded the various screams, barks, and who calls

made by a group of chimps including 17 youngsters living in the wild in the Gombe National Park in Tanzania.

Fonder Wright Ploy and her husband Franz Ploy were planning to study how chimp vocalizations

change over the life of an individual, but they ended up focusing on how baby

chimps behave, so their extensive recordings have remained largely unexplored.

One thing that pops out of this collection is that immature chimps grunt more than their adult counterparts,

which suggests that you might not want to talk to baby Bonzo before he's had his morning banana

smoothie.

Thanks for the minute.
