Elephants may call each other by name, a rare trait in nature - National Geographic

Amara: Welcome to The Long Memory — I'm Amara, an elephant biologist and science communicator, and this is the show where we go deep into the inner lives of the most extraordinary animals on Earth. So glad you're here with me today. Amara: Before we dive in, a warm thank you to our sponsors keeping this show alive: Ada, who helps businesses integrate A I meaningfully into their workflows; Ago Consulting — pronounced "Ahh-Go" — your partners in silicon development from A I all the way to SoC; and Zen Semiconductor, an umbrella company with a remarkable portfolio spanning the silicon industry. We genuinely appreciate their support. Amara: Today we have a lot to get into — and I think this episode might be one of my favorites so far. We're going to talk about something that gives me chills every time I think about it: the possibility that elephants call each other by name. We're going to spend time with the question of what it means to recognize another being as an individual, as someone with a name. Then we'll move into the heart of the herd — what holds these families together, what they feel, what they remember. And we'll end with some remarkable stories from Namibia, India, and China, where humans and elephants are navigating an increasingly complicated shared world. Let's go. Amara: MIND OF THE ELEPHANT Amara: Okay. So. Elephants may call each other by name. I want to sit with that for a second, because it's easy to gloss over a headline like that and just nod along — "oh, smart animals, sure." But what researchers are actually describing here is something genuinely rare in the animal kingdom, and I think it deserves a moment of real attention. Amara: The study, published in Nature Ecology and Evolution, was led by scientists at Colorado State University and Save the Elephants. They analyzed hundreds of elephant calls recorded in the wild in Kenya — in Amboseli National Park and Samburu National Reserve, two places where elephants have been studied closely for decades. And what they found is that elephants appear to address specific individuals using calls that aren't simply imitations of the recipient's own sounds. Amara: Now, here's why that matters. A lot of animal communication works through mimicry — a dolphin, for example, will copy another dolphin's signature whistle to address them. It's like saying someone's name by repeating the sound they make. But what the elephants seem to be doing is different. The calls directed at specific individuals contained something unique — a kind of label, an arbitrary vocal tag — that wasn't derived from the sound that individual makes. That's much closer to what we do when we use a name. Amara: The researchers played back recordings to elephants in the field. When a recording was played that contained a call apparently directed at that specific elephant, the elephant responded more strongly — approached faster, called back sooner — than when a call directed at a different elephant was played. The animal recognized, essentially, that this one is for me. Amara: I find this almost unbearably interesting, because names aren't just labels. Names are a form of acknowledgment. When you give something a name, you are saying: I see you as distinct. You are not interchangeable with the others. You are you. And if elephants are doing this — if a mother has a particular call she uses only for her youngest calf, if a matriarch has a sound she reserves for her sister — then we are looking at a society that, at some fundamental level, operates on individual recognition. Amara: That fits everything else we know about elephant cognition. These are animals with extraordinarily large and complex brains — the largest of any land animal in absolute terms. Their temporal lobes, the regions associated with memory and social cognition, are highly developed. They have spindle neurons — the same cells associated with self-awareness and social emotion in humans and great apes — located in areas of the brain linked to social behavior. Amara: And the memory! Matriarchs have been documented recognizing the calls of over 100 other elephants — family members, rivals, friends, former neighbors from groups they haven't encountered in years. There is a famous study from Amboseli where researcher Karen McComb and her colleagues played back the calls of matriarchs who had died, to living family members. The elephants who heard the voice of their deceased matriarch showed clear distress — touching each other, rumbling, clustering together. They remembered her. They knew her voice. And she was gone. Amara: So names. It makes sense, doesn't it? If you live in a society built on long memory, on knowing who is who and who can be trusted and who your grandmother was — of course you'd develop a way to call each other by something specific. Of course you'd have a word for each other. Amara: I think about a young elephant — let's call her a calf, maybe two years old, still figuring out the world — hearing her name rumbled across the savannah by her mother. And turning. Because she knows that sound. That sound is hers. Amara: HEART OF THE HERD Amara: There's a story I come back to often when I think about elephant emotion, and it comes from Cynthia Moss, who has spent more than fifty years studying the elephants of Amboseli. She documented a moment when a matriarch named Tonie gave birth to a stillborn calf. Tonie stood over the body for a long time. She tried to lift it with her trunk. She nudged it with her foot. Members of her family gathered around her. They touched the calf, they touched Tonie, they stood close. And then, slowly, reluctantly, the family moved on — because they had to, because survival requires movement, because calves need to drink and eat. And Tonie stayed behind. For as long as she could. Amara: That is grief. It may not be identical to human grief — and I always want to be careful about that, about projecting our experience wholesale onto another animal's — but it has the same shape. It has the weight of loss. The body that doesn't want to leave. Amara: What holds a herd together is, in a word, the matriarch. Elephant herds are organized around related females — mothers, daughters, sisters, aunts — and led by the oldest, most experienced female. She is the repository of the group's collective memory. She knows where the water is in a drought year. She knows which humans can be trusted and which cannot. She knows the sounds of lions and the sounds of bees and the difference between a harmless tourist vehicle and one that smells like a poacher. Amara: Studies by Karen McComb and her colleagues found that the larger a matriarch's social knowledge — measured by her ability to recognize the calls of other elephant groups — the better her family survived. Families led by older, more experienced matriarchs made better decisions in times of stress. They moved more cohesively. They lost fewer calves. The wisdom of one individual, accumulated over decades, translated directly into the survival of the group. Amara: And the bonds within that group — between sisters, between a mother and a daughter she has known for thirty years — are not casual. Researchers have documented what they call greeting ceremonies, where family members who have been separated for even a few hours come back together with an explosion of joy — rumbling, ear-flapping, spinning, touching each other's mouths and temporal glands. It looks, frankly, like what it is: delight. The relief and pleasure of reunion. Amara: There's a conversation happening right now about how we recognize this in law and policy. Down To Earth, an Indian environmental publication, recently raised the question of whether Kerala — a state in India with a long tradition of keeping captive elephants — should adopt what they call a sentience-rights-based approach to governing those animals. The argument is straightforward: if we accept that elephants are sentient — that they feel, that they remember, that they form meaningful social bonds — then the frameworks we use to manage them need to reflect that. Amara: It's a profound question. Kerala has hundreds of captive elephants, many of them used in religious festivals and temple processions — a practice with deep cultural roots and also deep complications. Captive elephants are often isolated from other elephants, chained for long periods, deprived of the social world they are built for. For an animal whose entire psychology is organized around relationships — around knowing the names of the people around them, around the comfort of a family that has been together for decades — solitary confinement is not a neutral condition. It causes suffering. The science is clear on this. Amara: Recognizing sentience in law doesn't mean elephants vote or own property. It means acknowledging that their capacity to suffer is real, that their social needs are real, that a being this complex deserves a framework that takes that complexity seriously. And I think — I hope — that the conversation Kerala is having now is one that will spread. Amara: Because you can't learn that elephants call each other by name, that they grieve their dead, that a matriarch carries fifty years of knowledge in her memory for the benefit of her family — you can't learn all of that and then look at a chained elephant standing alone in the heat and think: this is fine. Amara: AN ELEPHANT-AND-PEOPLE STORY Amara: The place is Namibia, and the situation there is one of the hardest kinds of stories to tell — because there are no villains, and there's no easy ending, and the stakes are enormous on every side. Amara: Namibia has done something remarkable. After decades of poaching that devastated wildlife populations across sub-Saharan Africa, Namibia built a community-based conservation model that genuinely worked. Local communities — many of them communal farmers living on ancestral land — were given rights over the wildlife on their land and a stake in its survival. Elephant populations recovered. Dramatically. Today Namibia has one of the largest elephant populations in Africa. Amara: And now those elephants are moving. Amara: The elephant corridor in northwestern Namibia runs through land that is shared — sometimes uneasily — by elephants and the people who farm there. As the elephant population has grown, and as climate change has made water and vegetation scarcer and less predictable, elephants are ranging further. They're moving through farms. They're eating crops. They're breaking fences and sometimes destroying the livelihoods that families have spent generations building. Amara: ScienceAlert reports that this tension is about to get worse. The combination of a growing elephant population and intensifying drought stress — both pushing elephants to move further and more desperately in search of resources — is set to increase human-wildlife conflict in the corridor. Amara: And here's what I want people to understand about this: the elephants are not doing anything wrong. They are following ancient migration routes that existed long before the farms did, long before the fences did. They are doing what elephants have always done — following the rains, following the memory of water that the matriarch carries in her mind. They don't know about property lines. They know about survival. Amara: And the farmers are not doing anything wrong. They are feeding their families. They have rights to their land and their livelihood. When an elephant walks through your fields at night and destroys the maize that was supposed to carry your children through the dry season — that is not an abstract conservation problem. That is a crisis. Amara: What gives me some genuine hope is the creative, urgent problem-solving happening right now — some of it in Namibia, some of it in India, some of it in China. Because technology is entering this conversation in ways that actually seem to be helping. Amara: In India, an IFS officer recently shared a video showing how an A I alert system helped stop an elephant herd from entering a village. The system — using camera traps and machine learning to detect elephant movement — sent early warnings that allowed villagers to take precautions before the herd arrived. No one was hurt. The elephants moved through. And crucially, nobody panicked and nobody retaliated. Amara: Something very similar happened in Yunnan, in southern China, where early warning systems have been in use for a few years now and have been credited with reducing both human casualties and retaliatory killings of elephants. You may remember the extraordinary story of the herd of wild Asian elephants in Yunnan that walked hundreds of miles north a few years ago — a journey that captivated the world. China mounted a massive operation to monitor and gently guide them back south, using drones and early warning systems and closed roads. Not a single elephant was harmed. Not a single person was seriously injured. It was imperfect, it was improvised, and it worked. Amara: What all of this points to is the same thing: coexistence is not impossible, but it requires investment. It requires the willingness to say that the lives of these animals matter enough to build systems that protect both them and us. Early warning alerts. Compensation schemes for farmers who lose crops. Wildlife corridors that give elephants somewhere to be that isn't a wheat field. Beehive fences — which elephants, who have a genuine fear of bees, will avoid — that create a buffer without a bullet. Amara: These things cost money. They cost political will. And they require people who live with elephants, who bear the real costs of coexistence, to be heard and compensated and included — not lectured to from a distance by conservation organizations who will never lose a crop to a three-ton visitor in the night. Amara: But when it works — and it does work, it is working in places right now — what you get is this: a herd of elephants moving through a landscape that remembers them. And people watching from a safe distance, maybe on their phones, getting an alert that says the herd is near, move your cattle, don't go out tonight. And in the morning, the elephants are gone, and the farm is intact, and everyone is okay. Amara: That's not a small thing. That's actually everything. Amara: There's something I think about a lot, at the end of days like this — days where I've spent hours reading about elephant calls and corridor conflicts and the slow, hard work of sharing a planet. And it's this: memory is not just something elephants have. Memory is what they are. The matriarch is her memory. The herd is the accumulated memory of every drought survived, every predator avoided, every family member known and loved and grieved. Amara: We are building our own memory of them, slowly. Science is filling in the picture — names, grief, joy, the particular rumble a mother uses for her calf. And the more we remember, and the more we understand, the harder it becomes to look away. The harder it becomes to say this doesn't matter. Amara: I think that's actually how coexistence happens. Not through technology alone, not through policy alone — though we need both — but through the accumulation of knowledge that makes indifference impossible.
