Episode transcript:

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This week’s episode was supposed to be about animals that were saved from extinction by human intervention, but between National Novel Writing Month, the Thanksgiving holidays, and the release of Animal Crossing: Pocket Camp I didn’t get the research completed. So that episode will run in a week or two and we’ll learn about something else this week. Something short, because it’s Sunday and I need to get this episode edited and uploaded so you can listen to it first thing Monday morning.

But first, I want to tell you about an awesome podcast who had me as a guest last week. If you don’t already listen to Relic: The Lost Treasure podcast, I highly recommend it. It’s family friendly and a great take on an aspect of history that doesn’t always get the in-depth research it deserves. In between regular seasons, the host, Maxwell, releases roundtable discussion episodes with different people to cover topics that maybe aren’t exactly about lost treasure, but close. I appeared in episode 15, called “Back from Extinction,” where we discussed animals that were declared extinct but have been rediscovered, although not without controversy. I’ll put a link in the show notes so you can go check that one out. I’d planned my own saved from extinction episode as a sort of follow-up, but time got away from me.

So what are we talking about today? In honor of the end of National Novel Writing Month, which is kicking my butt this year, we’re investigating a mystery animal called the Chinese Ink Monkey.

The story goes that in antiquity, as far back as 2,000 BCE, a tiny primate known as an ink monkey was frequently the pet of scholars and scribes in China. It wasn’t just a cute little pet, it was useful. It was intelligent and could be trained to prepare ink, which back in those days came in blocks and had to be ground into powder and mixed with water to the right consistency. It would turn book pages so the scholar could read hands-free, it would hand pens and other items to the scholar, and it was small enough to sleep in the scholar’s brush pot or desk drawer. Such a useful little creature was highly sought after, but was supposed to have gone extinct at some point centuries ago.

According to a book of Chinese lore called The Dragon Book, published in English in 1938, the ink monkey was only around 5 inches long, or 13 cm. Its sleek fur was black and soft and it had red eyes. It was also supposed to drink any ink remaining at the end of the day as its preferred food.

Since ink in those days was frequently made with precious materials like sandalwood, crushed pearls, musk, rare herbs, and even gold, and those things are not just valuable, they’re not all that nutritious, ink monkeys probably didn’t actually drink ink. But was it even a real animal or just a legend?

In April of 1996, the ink monkey story got media attention when a press release from the official New China News Agency announced its rediscovery in the Wuyi Mountains of Fujian Province. The press release didn’t have many details at all. It basically just reported that the animal was mouse-sized and had been found.

The smallest monkey alive today is the pygmy marmoset from South America, which is about 10 inches long, or almost 26 cm. But there is another animal that looks like a monkey but which is no more than about six inches long, or 15 cm, not counting its tail.

The tarsier is a nocturnal primate with huge round eyes, mouse-like ears, and sucker-like discs at the ends of its toes which it uses to climb trees. Its tail is extremely long, as are its hind legs, which helps it jump through the trees where it spends almost its whole life. While the various species of tarsier are only found on various islands of Southeast Asia today, they were once more widespread. One extinct species did live in China, but not recently. Not even remotely recently. More like 35 to 40 million years ago.

The smallest species is the pygmy tarsier, which is only found in central Sulawesi in Indonesia. It was thought extinct for decades until 2000, when it was rediscovered by local scientists. It’s only about four inches long, or 10.5 cm.

There’s still some controversy as to whether the tarsier is actually a primate. DNA studies haven’t cleared it up yet. But one thing is clear: the tarsier is a heckin adorable little guy. Its eyes are each as big as its brain and most pictures of tarsiers taken in daylight show it squinting as though it’s considering an important philosophical question. The tarsier’s fur is soft, usually beige or orangey in color, and its eyes are golden.

We’ve met the tarsier before briefly in episode eight, the strange recordings episode, because the tarsier communicates in infrasound—sounds too high for humans to hear. It’s carnivorous too, mostly eating insects but it will also eat birds, bats, and reptiles when it can catch them.

But back to the press release that the ink monkey had been rediscovered in China. At least one imminent naturalist, Sir David Attenborough himself, suggested that a species of tarsier might easily have been living in China all along without being known to science. While it is doubtful that a tarsier could learn to prepare ink or turn book pages, it’s also possible that if a famous scholar kept one as a pet, the story of its helpfulness might have been added over the centuries.

The mystery of the ink monkey’s rediscovery was cleared up by zoologist Karl Shuker, who is basically the expert on the ink monkey. Most of my research for this episode comes from his book The Search for the Last Undiscovered Animals. I’ll put a link in the show notes, of course. He discovered that a few weeks before the official press release, a short account of a discovery was published in the London Times on April 5, 1996. That report was about the discovery of a mouse-sized primate in China, sure, but not a living animal. This was a fossil discovery—specifically, a fossil jaw of an tiny proto-monkey that lived around 43 million years ago.

As Shuker concludes, the confusion probably stems from a poor English translation in the press release, leading to reporters thinking a live animal had been discovered.

But that doesn’t mean there wasn’t once a real primate that gave rise to the Chinese ink monkey legend—whether it’s a tarsier or an actual monkey or something else Maybe one day we’ll find out.

That’s it for this episode. I warned you it would be short. To make it up to you, I’ll unlock another Patreon episode for anyone to listen to, this one about mammoths and mastodons. That one probably should have been a regular episode anyway. I’ll put a link directly to the episode in the show notes and you don’t need a Patreon login to listen to it, just click the link and press play.

Kinship with Animals by Dave Soldier

Show transcript:

Welcome to Strange Animals Podcast. I’m your host, Kate Shaw.

This week’s episode about nonhuman musicians was inspired by an article about palm cockatoos. The male cockatoos drum on tree trunks or hollow logs as part of their courtship display, which doesn’t sound all that unusual until you learn that they use special crafted sticks to drum. A male will select a stick, trim it down the way he wants it, and hold it in his claw to drum. Sometimes he’ll use a hard seedpod instead. The resulting beats are not only consistently in rhythm, each individual has a personal style. Some drum quickly, some slowly, some throw in little flourishes. Sometimes females will drum too, and if a female likes a male’s drumming, she may imitate him or join in.

Here’s a little clip of a male drumming. He’s also whistling.

[palm cockatoo drumming]

The palm cockatoo is an awesome-looking bird. It looks like a drummer. It’s up to two feet long, or 61 cm, smoky gray or gray-black with a heavy gray beak, red cheek patches that flush when the bird is upset or excited, and a messy crest of feathers. It’s native to Papua New Guinea, Indonesia, and the very northern tip of Australia, Cape York Peninsula. Only the Australian birds are known to drum. Unfortunately, the Australian birds are the ones most threatened in the wild due to habitat loss.

The palm cockatoo eats nuts and seeds, and like all parrots it can live a long time. And yes, you can get them as pets—and now I’m desperate for one even though the last thing I need is a pet cockatoo. I have a coworker with a pet parrot who she says is incredibly neurotic. He tends to get overexcited and starts screaming, and she has to put him in his cage and cover it so he’ll shut up. Her kids found the parrot when they were young. He plopped down in her yard when they were playing outside, and they put an empty laundry basket over him to trap him. No one claimed him, so my coworker has now been stuck with a neurotic parrot for over twenty years. She’s pretty sure he survived in the wild by hanging out with crows, because one of the things that will set off his excited screaming is hearing crows outside. And while cockatoos and parrots in general are typically affectionate and make good pets, palm cockatoos are not. They’re considered “difficult.” When parrot fanciers call a type of bird difficult, it’s difficult.

Anyway, the really unusual thing about the palm cockatoo’s drumming isn’t its tool use, which is well known among many types of birds, especially parrots and their relations. It’s the rhythm.

Most animals can’t keep a beat. Synchronization to an external rhythm is called rhythmic entrainment. Humans are really good at it and recognize a beat automatically, but responding in time to a rhythm is a learned skill. Small children have to learn to keep a beat by moving their bodies, speaking, or singing, and they learn it best in social settings. That’s why music, dance, and rhythmic play activities are so important to preschool children. And as a drummer myself, I promise you, humans of any age can learn to improve their rhythm.

But most animals don’t seem to have the ability to distinguish rhythmic beats, although it hasn’t been studied all that much until fairly recently. Some researchers think it may have something to do with the ability to mimic vocal sounds.

That would explain why many birds show rhythmic entrainment, varying from species to species. A sulfur-crested cockatoo named Snowball was internet-famous for a while in clips where the bird danced to music. As a result, Snowball became the subject of a rhythmic entrainment study that shows he can adapt his dancing to changing tempos.

But not all animals who show rhythmic entrainment can mimic vocally. California sea lions aren’t exactly the parrots of the sea animal world, but they can be trained to move to a beat. On the other hand, closely related seals are vocal learners. In fact, one famous harbor seal who was raised by a fisherman who found the orphaned pup could imitate the fisherman so well he was known as “Hoover the Talking Seal.”

Here’s the only clip I would find of Hoover. The first time I listened to it, I couldn’t figure out when the seal was talking. All I could hear was some gruff-sounding guy talking really fast. Well, that’s Hoover.

[Hoover the talking seal]

That is Hoover the talking seal talking. It’s creepy as heck.

It’s possible that sea lions still retain neural pathways that allow vocal mimicking even if they no longer use them. Then again, some researchers now believe that vocal mimicking ability may only be a skill related to rhythmic entrainment, not the source of the ability, and that the neural pathways for rhythmic entrainment may be very old. Some species can express entrainment, others appear to have lost it.

Studies on human brains show that when music plays, pretty much the entire brain lights up in response. That’s because we have special neural connections that help coordinate motor planning, speech, and other skills with the perceived beat. Brains of parrots and other birds are very similar. But monkeys are not. Monkeys can’t dance. Poor monkeys.

One study with rhesus monkeys who were trained to tap in rhythm with a metronome determined that they couldn’t anticipate the beat but could tap just after it, responding to it, even after years of training. Many rhythmic entrainment studies focus on great apes, since it’s reasonable to suppose that humans’ close cousins might share our rhythmic ability.

Patricia Grey, a bio-music researcher at the University of North Carolina at Greensboro, taught a group of captive bonobo apes to play a drum along with a beat. But it wasn’t as simple as showing a bonobo how a drum worked and seeing if it could keep a beat. She had to encourage the apes in a social setting, just like with human children. Also, she had to design a drum that could take a whole lot of abuse. I love that she went to Remo, a company that manufactures drums and drumheads, to have the drum made.

Her experiment started by accident. In 2010, Grey was at the Great Ape Research Center in Des Moines waiting for an experiment to be set up, and while she waited she idly tapped the glass on the bonobo enclosure. A bonobo named Kanzi came over and tapped her hand on the glass in response, matching Grey’s tempo. Intrigued, Grey continued tapping to see how long Kanzi would keep it up. Kanzi didn’t stop, even when her snack time came. She ate her snack lying on her back so she could continue to tap with her feet.

Wild chimpanzees and bonobos drum on logs and their own bodies to make rhythmic noise during play and dominance activities. Dominant male chimps do a particularly exaggerated slow display when thunderstorms approach, called a rain dance by researchers, that involves drumming. A variation of the rain dance has been seen when wildfires are approaching a troupe of chimps. Naturally it’s called a fire dance, and it includes a vocalization heard at no other time.

Chimps are pretty chill when it comes to fire, by the way. They understand how it spreads and how to avoid it without panicking.

Another animal that can keep the beat? Elephants! Asian elephants are vocal mimics and their ability to keep a beat is extremely precise. In 2000, the Thai Elephant Orchestra was created with elephants at a conservation center in Thailand, who learned to play oversized versions of traditional Thai percussion instruments.

The elephants learned the instruments easily, taking to it so quickly and so well that the orchestra’s founders were astonished. The great thing is, the elephants actually create much of the music themselves. The orchestra’s founders, neuroscientist Dave Soldier and elephant conservationist Richard Lair, wanted the elephants to have fun and enjoy making music. So for most songs, the animals are only signaled when to start and stop playing. Occasionally human musicians play along.

The orchestra released three albums between 2002 and 2011, which were all well received—not as novelty albums, but as actual improvisational compositions. Some of the songs are arranged, with the elephants trained to play traditional Thai music. The orchestra performs live for visitors at the conservation center.

The orchestra varies in size from five to fourteen elephants. One particularly talented drummer, Luk Kop, could play three drums at the same time and set up complex rhythms. Unfortunately he was also a dangerous elephant, and that’s not good for a band or an elephant orchestra, so he had to drop out.

The elephants prefer non-dissonant tones and learn to strike the properly resonant parts of their instruments without even being taught. The elephants at the center also enjoy playing harmonicas. The tip of an elephant’s trunk has a fingerlike projection, so an elephant can hold a harmonica and blow through it with its trunk. Soldier reports that one morning he arrived at the center early when the elephants were heading down to the river for their morning bath. Almost all the elephants had brought their harmonicas and were playing together as they walked.

Most of the elephants at the center are former logging animals, and many of their handlers, known as mahouts, once worked with them when they were logging. Mahouts traditionally sing to their elephants, which is supposed to keep them calm. So the elephants in the orchestra are familiar with traditional Thai music.

Locals who have heard the orchestra play say the music sounds like the music in Buddhist temples. Soldier, a musician and composer himself, transcribed an original elephant piece which was then played by a human orchestra in New York. The audience didn’t know it was composed by elephants. Some guesses as to who the composer might be included John Cage, Dvorak, and Charles Ives.

Whether or not you like improvisational Thai music played by elephants, or you think it’s just a stupid gimmick, it’s clear the elephants are having a lot of fun. Here’s a clip of some of their music recorded at the conservation center. That’s some mighty fine percussion for animals who don’t even have hands.
