Elephants Call Each Other By Name, Study Says

Elephants encode names and other information in low-frequency rumbles that can be heard miles away. For social animals who live in large herds, it’s crucial to be able to address individuals.

Elephants are famously social animals, moving in matriarchal herds that can consist of as many as 70 of their kind.

They also communicate over long distances, emitting rumbles that can be heard miles away.

Because of their social and nomadic existence, it makes sense that elephants would need a way to single out individuals and address each other, and for the first time researchers say they’ve found evidence of Earth’s largest land animals calling each other by name.

“If you’re looking after a large family, you’ve got to be able to say, ‘Hey, Virginia, get over here!’” Duke University ecologist Stuart Pimm told the Associated Press.

The research involved field work and analysis using artificial intelligence. To record samples of elephants communicating, teams followed herds with recording equipment. Notably, elephant rumbles include sounds in frequencies lower than the human ear can detect.

The team paid close attention when one elephant vocalized and another responded, and recorded who initiated each rumble and who it was meant for.

Although elephants are best known for making loud “trumpeting” sounds, experts say those are more like exclamations while rumbles contain encoded information that African savanna elephants would need to communicate to each other.

“The rumbles themselves are highly structurally variable,” said Mickey Pardo, a biologist from Cornell University and co-author of the study. “There’s quite a lot of variation in their acoustic structure.”

A machine learning algorithm was then used to sort and categorize the large number of audio samples, looking for patterns that are difficult for human minds to detect.

“Elephants are incredibly social, always talking and touching each other — this naming is probably one of the things that underpins their ability to communicate to individuals,” said George Wittemyer, an ecologist at Colorado State University and co-author of the study. “We just cracked open the door a bit to the elephant mind.”

Notably, the elephant “names” are identifiers that they created for themselves, and are not the kind of human-bestowed names that cats and dogs respond to. The list of animals who have names for themselves is short, although likely to expand with further study. Dolphins, for instance, identify themselves with unique whistling patterns, and parrots have a similar method, but both species address individuals by imitating their calls. Elephants use their name analogs the way humans do, to directly address each other.

The research has the potential to raise public awareness of elephant intelligence and their plight as they face threats to their continued existence. Like almost all of the Earth’s iconic megafauna, elephants will become extinct if we don’t do a better job protecting them and ending the ivory trade. Every year about 20,000 elephants are slaughtered for their tusks to feed the demand for ivory, especially in China where it’s considered a status symbol, according to the World Wildlife Fund.

Yang Feng Glan, known as the”Queen of Ivory,” was sentenced to 15 years in prison by a Tanzanian court in 2019. Yang smuggled some 860 elephant tusks worth $6.5 million from Tanzania to China as the leader of one of the world’s most extensive poaching and ivory smuggling organizations.

During her years operating the smuggling ring, Yang presented herself as a successful businesswoman and ran in elite circles within China, authorities said. Two of her accomplices were also given 15-year sentences for their roles, but since then others have filled the vacuum left by Fang’s conviction, and elephant preserves are constantly under threat from heavily armed poachers.

Foundation Offers $10m For ‘Cracking The Code’ Of Animal Language

Think you can decipher the rhythmic clicks and whistles of dolphins or the grunts and alarm calls of monkeys? A foundation is offering big prizes for progress in communicating with animals.

Looking to prompt renewed efforts at decoding animal communication, a non-profit founded by an investor and a university are offering prizes — including a hefty $10 million — to teams that can figure out what animals are “saying.”

The Coller Dolittle Challenge for Interspecies Two-Way Communication is a collaboration between the Jeremy Coller Foundation and Tel Aviv University. (Yes, it’s named after that Dr. Dolittle.)

Entrants aren’t asked to come up with a Star Trek-like “universal translator” for animals. Rather, the people behind the Coller Dolittle Challenge want to see methods that allow for two-way communication between humans and individual species.

“We are open to any organism and any modality from acoustic communication in whales to chemical communication in worms,” said Yossi Yovel, a professor at Tel Aviv University and co-chairman of the challenge.

The grand prize is a $10 million grant or $500,000 in cash, chosen by the winner, while the Foundation will offer $100,000 prizes each year for the best entries that make significant progress toward communicating with animals. The yearly prizes will be assessed “for significant contributions to decipher, interface or mimic non-human organism communication.”

While it may seem far-fetched — and there are those who believe humans will never be able to fully understand animal communication in proper context — there have been efforts to communicate with and decode the communications of bats, dolphins, whales and some primate species. Scientists have also pushed the boundaries on understanding group communication, such as the coordination involved in avian murmurations.

The organizers believe artificial intelligence will be the tool that ultimately helps crack the communication barrier, but entrants aren’t required to use AI. The technology is incredibly useful for tasks involving pattern recognition and sorting large amounts of data, both of which are important in this kind of work when researchers are tasked with analyzing thousands of audio samples or hundreds of hours of footage.

Alas, we don’t think the foundation will be interested in the Buddinese language, which boasts 327 different ways of demanding food and features a timekeeping and calendar system based on meals and naps. A short trill followed by a series of staccato meows, for example, means “I expect prompt service at salmon o’clock,” while a truncated meow ending with a scoff is used to indicate displeasure when a human napping substrate tosses too much during sleep.

Still, maybe we’ll dress it up to make it look properly academic and give the challenge a try. Those prizes could buy a lot of Roombas!

The Dividing Line Between Human And Animal Has Been Blurred Again As AI Reveals Startlingly Complex Whale Language

By unlocking the mysteries of how sperm whales communicate and demonstrating their impressive cognitive abilities, researchers hope to get people invested in the fate of these endangered animals.

Sperm whales are chatty.

Their language is markedly different from the deep cetacean moans associated with other whales, taking the form of Morse code-like clicks that boom through the ocean in a decibel range almost twice that of jet engines.

And while we’ve long known animals like monkeys assign specific meaning to short vocalizations varying from alarm calls to affirmations of social rank, sperm whale conversations can endure for an hour or more, with participants exchanging complex strings of clicks that vary depending on context, environment and even which pod family is speaking.

While artificial intelligence has been maligned over the past few years as people grapple with its rapid progress and potential for abuse, it remains the best tool we have for teasing out patterns that our human minds can’t discern, especially from large quantities of data.

With more than 9,000 recordings of sperm whales, Project CETI — Cetacean Translation Initiative, a non-profit effort to decode and translate sperm whale communication — had precisely the kind of huge data cache that AI excels at analyzing.

By feeding the recordings into specially trained machine learning algorithms, the research team was able to identify a wealth of new language patterns. While human languages are composed of quantized morphemes — prefixes, suffixes and root words — whale communication is broken down into sequences of clicks and pauses called “codas.”

Like Morse code, codas make a distinction between short clicks and long clicks. Sperm whales also vary the tempo of the clicks, which could represent inflection, “dialects” or concepts completely alien to the human mind.

“Some of what they’re doing might be totally different from our way of communicating and we’re probably never going to be able to fully grasp those differences,” Oregon State postdoctoral marine researcher Taylor Hersh told NPR.

Researchers believe the “inter-click intervals” — akin to ghost notes in music — may be as significant as the clicks themselves. Importantly, while human ears were able to identify and catalog some of the codas, the machine learning algorithms found many that human analysis missed.

That’s not surprising considering sperm whales — the loudest animals on Earth, capable of generating sounds up to 230 dB — took a much different evolutionary course and, as ocean-dwelling creatures weighing up to 90,000 pounds (40,800 kg) likely have a radically different sensorium compared to humans.

The comparisons to music go further than ghost notes.

“This study shows that coda types are not arbitrary, but rather that they form a newly discovered combinatorial coding system in which the musical concepts of rubato and ornamentation combine with two categorical, context-independent features known as rhythm and tempo, by analogy to musical terminology,” CETI’s team wrote on May 7 while unveiling the most recent study.

While people have used many abilities to mark the dividing line between humans and animals over the years — including the ability to use tools, experience emotions, and demonstrate self-awareness — human capacity for authentic language with syntax and context-dependent meaning was one of the stalwarts, standing the test of time as new research toppled the other dividers by showing animals do indeed use tools, experience rich emotions and have complex inner mental lives.

With this research, scientists are assembling a “sperm whale phonetic alphabet” that will make it easier to discern and catalog whale codas.

To be clear, there’s still a lot of work ahead before scientists can prove sperm whale codas are comparable to human definitions of language, but whether they strictly meet that definition may not matter. After all, it’s clear the clicks and pauses of whale codas are imbued with meaning, even if it remains elusive to us for the moment.

Indeed, “sperm whale communication has both contextual and combinatorial structure not previously observed in whale communication,” the team wrote.

Proving sperm whale codas are tantamount to human language isn’t the goal anyway. The team has two overriding priorities — decode the meanings behind the codas, and get the wider public invested in the fate of these endangered animals by showing they’re not so different from us.

“Our results show there is much more complexity than previously believed,” MIT AI lab director Daniela Rus told NPR, “and this is challenging the current state of the art or state of beliefs about the animal world.”

This Parrot Loves Earth, Wind And Fire

The last few decades have revealed birds like crows and parrots possess astonishing intelligence. “Bird brain” might not be much of an insult after all.

Meet Kiki the cockatiel, a bird who loves Earth, Wind and Fire so much that he sings the band’s classic hit, September, regularly — whether he’s just chilling by himself, singing along to the recording or driving his human crazy by whistling the catchy hook at ungodly hours.

“Kiki, it’s seven in the morning!” she tells him in one clip, raising an admonishing finger. “Silence!”

@kiki.tiel

Kiki regards her for moment as if her request is absurd, then launches right back into September.

Hey, hey, hey
Ba-dee-ya, say, do you remember?
Ba-dee-ya, dancin’ in September
Ba-dee-ya, never was a cloudy day

In another video Kiki’s human sets her phone to record and leaves the room, and Kiki busts out his favorite song again. He’s got great taste in music!

I’ve always thought parrots are a fascinating example of animal cognition and further proof that we share our planet with billions of other minds who think and feel.

Humans and birds last shared a common ancestor more than 300 million years ago. That means between them there’s been more than 600 million years of divergent evolution resulting in radically different physiology, abilities and minds.

Yet parrots can speak while non-human primates (apes and monkeys) cannot!

For decades scientists thought apes and monkeys, by virtue of their relative similarity to humans, possessed an inmate affinity for language and that the physical limits of their vocal apparatus is what keeps them from speaking.

But a 2016 study by a team from Princeton University found monkeys do possess the vocal “hardware” to speak, meaning their mouths and throats are capable of making the sounds necessary for human language. It’s the lack of associated brain circuitry that prevents them from talking.

If the ability to speak and the ability to dance/appreciate music and rhythm is uniquely human among the primate order, and birds arrived at it at a different point in their evolutionary history, that means language and appreciation for music/rhythm developed separately along two divergent evolutionary lines!

That’s incredible and has intriguing implications for the cognitive abilities of animals.

A common argument is that birds with the ability to form human speech are simply mimicking sounds and don’t understand what they’re saying. That’s a natural assumption given what we think we know about non-human capacity for understanding language, but research suggests it’s wrong.

Take a look at this video of the famous late African grey parrot, Alex:

When Dr. Irene Pepperberg asks Alex how many blue blocks are present on a tray with a random assortment of blocks, balls and triangular toys in different colors, Alex can’t give a rote answer. First he has to understand that a question is a request for information and not part of the strange human ritual called small talk. He can’t simply count or guess at the number of blocks either.

Instead, Alex has to perform two calculations. He must tally the blue objects and count the number of them that are blocks, or he’s got to count the number of blocks and figure out how many of them are blue.

If he was simply repeating information in context — like saying “Hello!” when a person walks into a room — Alex wouldn’t be able to correctly answer the questions, and Pepperberg’s research funding would have dried up. Instead, Alex became a focal point of research that persisted for decades.

There’s no indication Alex could master syntax, which has proven elusive for even the smartest animals. But the African grey, who died in 2007 at 31 years old, was curious, asking questions that were unique and unexpected of an animal. He once asked his caretakers to describe his physical appearance, and the night before he died, he told Pepperberg: “You be good. I love you. See you tomorrow.”

We’ve talked about parrots before on PITB, including Snowball the dancing cockatiel who not only appreciates music and has a great sense of rhythm, but also has an entire repertoire of unique dance moves. Then there’s my personal favorite, Ruby the African grey, who has demonstrated mastery of absolutely vile, uniquely British insults.

Sure, there may not be much research value in hearing Ruby hurl verbal abuse at her very loving human, Nick Chapman, but few things have made me laugh as hard as that extraordinarily foul-mouthed bird. She has to be seen and heard to be believed. (But if you’ve got kids in the room, stick with the wholesome Snowball. He’s got serious moves.)

Snowball the dancing parrot — Scientists credit Snowball with choreographing his own dance routines, with dozens of individual dance moves and combinations, and moves that change depending on the song he’s rocking out to.

Now if you’ll excuse me, I’m off to teach a certain feline a few Earth, Wind and Fire songs in the hope that he’ll give up on the screeching meows and use his natural falsetto for a more gentle wake-up experience.

Hey, hey, hey
Ba-dee-ya, hey there my Big Buddy
Ba-dee-ya, Little Buddy’s hungry!
Ba-dee-ya, get your lazy ass up and feeeeeed me!

Cat Domestication Was The Start Of A Beautiful Friendship

Domestication’s real goal: to make cats cuddly as well as great mousers.

Cats have been doing things their way since the very beginning.

Unlike literally every other domesticated animal, cats were not domesticated by humans. They did it to themselves.

As if that didn’t make them unique enough, they lay claim to another major distinction: they’re the only species of obligate carnivores to undergo domestication in the entire history of human existence.

That explains why cats, more than any other animal that depends on humans, so closely resemble the wild animals they were before signing up for the good life of naps, warmth, endless rodents to hunt and free food from their new human friends.

In a new essay for The Conversation, evolutionary biologist Jonathan Losos, author of The Age of Cats: From the Savanna to Your Sofa, notes new DNA analysis settles the question of where cats came from once and for all.

Domestic cats are descended from North African wildcats, specifically the species felis sylvestris lybica. Unlike dogs, who underwent telltale physical transformations when they evolved from wolves, house cats “appear basically indistinguishable from wildcats.”

“In fact,” Losos writes, “only 13 genes have been changed by natural selection during the domestication process. By contrast, almost three times as many genes changed during the descent of dogs from wolves.”

While the change in genetics that happen with domestication left cats pretty much as they were physically, the process made dramatic changes in the feline brain, reducing regions governing fear and expanding those related to social behavior. The result? The major difference between house cats and their wildcat ancestors is disposition.

In other words, domestication made cats cuddly.

Notably, felis sylvestris lybica had to be pretty friendly in the first place, as well as bold and driven by the now-legendary feline curiosity to risk padding into human settlements with their bright lights, strange smells, open flames and the two-legged giants striding around them.

They didn’t have a way of negotiating or signaling their intent. They couldn’t say: “Hey guys, we’re here to kill and eat the tasty rodents who have been giving you problems by chowing down on your yums, but we don’t want your yums for ourselves. Plants are disgusting!”

So they had to demonstrate their usefulness, prove their worth, and enjoy the fruits of it by curling up in front of warm fires or on human laps.

That explains why it was the African wildcat that became a human companion species and not European wildcats, whom Losos notes are often “hellaciously mean” in interactions with people, even if they’re raised around humans when they’re young. It was also a matter of being in the right place at the right time, as nascent human civilization took root in the Fertile Crescent.

But ultimately, just like cats decided to domesticate themselves and didn’t really bother to consult us about it, so too do they bend us to their will with an entire repertoire of manipulative behavior, from solicitation purrs to incessant meowing and having a talent for looking their cutest when they want something.

While we may think we set the rules and parameters of our relationship with the furry little ones, as Losos notes, “cats usually train us more than we train them.”
