Linh Mai Inspires a New Era for the Zoo’s Elephant Cam - Smithsonian Magazine

Amara: Welcome to The Long Memory — I'm Amara, an elephant biologist and science communicator, and this is the show where we follow the inner lives of the largest minds on land. Today we have a beautiful range of stories for you: a camera that's quietly revolutionizing how we watch elephants learn, a legend of conservation whose life's work shaped everything we know about wild elephant society, an art exhibit in Boston that's bringing an Indian herd to life in the middle of a city, the story of a researcher who studied elephant behavior to literally save human lives, and a farewell to a matriarch named Stephanie who held her zoo family together for decades. Before we dive in, a warm thank you to today's sponsors — Ada, who helps clients integrate A I into their workflows; Ago Consulting, silicon development consulting from A I to SoC; and Zen Semiconductor, an umbrella company with a portfolio across the silicon industry. These are the folks who keep the lights on here, and I'm genuinely grateful. Alright — let's go. Amara: MIND OF THE ELEPHANT. Amara: So I want to start with something that might sound small but is actually kind of profound — a camera. Specifically, the elephant cam at the Smithsonian's National Zoo in Washington D.C., and the elephant who inspired it to become something much more than a live feed. Her name is Linh Mai. She's an Asian elephant, and over the past couple of years she has become — somewhat inadvertently — a window into how elephants learn, explore, and engage with their environment in real time. Amara: What happened is this: zoo researchers and staff began noticing that Linh Mai's behavior in front of the cam wasn't passive. She wasn't just existing in frame. She was investigating things. She was interacting with enrichment objects in sequences that showed real problem-solving. And the cam, which had previously been a lovely but fairly static viewer experience, started being used as an actual observational tool — a way to log behavioral data continuously, in a way that's very hard to do in the field. Amara: Now this matters because one of the perennial challenges in elephant cognition research is sample size and continuity. You can't put an elephant in a lab. You can run structured experiments — and researchers do, beautifully — but the messy, spontaneous stuff, the choices an elephant makes when nobody's watching, or when they think nobody's watching, that's where so much of the richest behavior lives. Continuous camera observation fills some of that gap. Amara: And what we've learned from watching elephants like Linh Mai over long, uninterrupted periods is consistent with what field researchers have documented for decades: elephants are curious in a purposeful way. They don't just mouth things or push them. They appear to test hypotheses. You'll see an elephant pick up an object, put it down, come back to it, try a different approach. That is iterative problem-solving. That is a mind working. Amara: Asian elephants in particular have shown remarkable results in controlled cognition studies. They pass the mirror self-recognition test — only a small handful of species do that, great apes, dolphins, and a few corvids among them. They use tools: in documented cases, Asian elephants have used sticks to scratch themselves in places their trunks can't reach, and they've been observed modifying objects before use, which is a more advanced form of tool use than simple pickup-and-apply. They understand pointing gestures from humans, which sounds simple but is actually cognitively demanding — most animals don't get it. They follow a human's gaze. They understand what it means when someone looks at something. Amara: And their memory — which is of course at the heart of everything we talk about on this show — is staggering. Elephants in the wild have been documented recognizing the calls of over two hundred individual elephants. They remember the locations of water sources they visited once, years before. Matriarchs carry spatial and social knowledge that goes back decades. The brain architecture that supports this is physically large: the elephant hippocampus, which is critical for memory formation and spatial navigation, is proportionally enormous. This isn't metaphor. The long memory is literal. Amara: So when a camera at a zoo helps us observe even a fraction of that inner life playing out in real time — a young elephant investigating a new object, returning to it, solving it — that's not a small thing. That's a reminder that the mind we're looking at is genuinely complex, genuinely active, and genuinely worth our sustained attention. Amara: HEART OF THE HERD. Amara: I want to take a moment here to honor someone. The Wildlife Conservation Society recently published a tribute to Iain Douglas-Hamilton, one of the most significant elephant researchers and conservationists of the twentieth and twenty-first centuries. Iain founded Save the Elephants and spent decades — literally his entire adult life — studying and advocating for African elephants. He died earlier this year, and the field of elephant science lost one of its great architects. Amara: I think the right way to honor Iain's work in this segment is to talk about what he gave us — because what he gave us is precisely this: the knowledge that elephant society is a society. Not a loose aggregation of large animals, but a structured, emotionally complex, multigenerational community governed by memory and matriarchy. Amara: Iain's early work in the 1960s and 70s in Lake Manyara National Park in Tanzania was among the first systematic long-term studies of wild elephant behavior. He was among the first researchers to individually identify elephants and track them over years — and what that longitudinal view revealed changed everything. You could suddenly see that these animals had relationships. That the same individuals sought each other out. That older females led, and that their leadership wasn't arbitrary — it was informed by experience and remembered knowledge. Amara: The matriarch is everything in an elephant herd. She is the living library. She remembers where the water is in drought years. She remembers which humans or predators to fear and which to tolerate. She knows the calls of family members who haven't been seen in years. Cynthia Moss, who collaborated with and was inspired by Iain's approach, documented this beautifully over forty-plus years at Amboseli — and what her research and Iain's together showed is that the death of a matriarch is not just a loss. It is a cognitive catastrophe for the herd. Amara: Herds that lose their matriarch make worse decisions. They're less able to navigate to resources. They show more fear responses, more confusion in the face of novel threats. The knowledge she carried doesn't transfer automatically — it has to be rebuilt, slowly, over years, by the next eldest female who steps into that role. Amara: And the grief. I have to talk about the grief, because it's one of the most well-documented and most moving things we know about elephants. They return to the bones of their dead. Not just to any bones — to the bones of their own. Cynthia Moss documented families returning to the skeletal remains of dead relatives and spending extended time touching the bones with their trunks, particularly the skulls. They have been observed doing this with the remains of individuals they were closely bonded with years earlier. They don't do this with the bones of other species. Amara: What does that mean? We should be careful about the word grief — we can't fully know what the internal experience is. But the behavioral markers are there: vocalizations, a particular slowed quality to movement, time spent that has no survival function, repeated return visits. Whatever word you want to use for it, something is happening. Something that recognizes loss. Amara: Iain Douglas-Hamilton knew this. He devoted his life to making sure the world knew it too. Rest, Iain. Amara: And while I'm thinking about loss and legacy — I also want to say a few words about Stephanie. The Sedgwick County Zoo in Wichita, Kansas, recently announced the death of their elephant matriarch, Stephanie, who had been at the zoo for decades. She was, by all accounts, exactly what the word matriarch implies: a steadying presence, a social anchor, the one the other elephants organized themselves around. Amara: In zoo settings, matriarchs play the same role they do in the wild — they provide social stability. They are who younger elephants look to when something is unfamiliar or frightening. The loss of that figure ripples through the whole social group. Zookeepers and elephant care staff at Sedgwick are undoubtedly paying close attention right now to how the remaining elephants are coping, monitoring for signs of social disruption and doing the patient work of helping the herd find its new shape. That work is as important as any veterinary care. Social wellbeing and emotional wellbeing are not separate things for elephants. They never have been. Amara: Goodbye, Stephanie. You held your people together. That is no small thing. Amara: AN ELEPHANT-AND-PEOPLE STORY. Amara: Okay, two stories here — and they couldn't be more different in setting, but they're both about the same underlying question: how do we live alongside elephants? And what happens when we actually try to understand them? Amara: The first is about a researcher. The New York Times recently ran a piece about a scientist who studied elephant behavior not for conservation in the traditional sense — but to save human lives. Human lives. The conflict angle. Because here's a reality that conservation communication sometimes soft-pedals: elephants and humans are in serious, sometimes deadly conflict across Asia and Africa. Elephants raid crops. They destroy homes. People are killed — and so are elephants, in retaliation. It is a humanitarian crisis and a conservation crisis at the same time, and they are inextricably linked. Amara: What this researcher understood is that you cannot solve human-elephant conflict without understanding elephant behavior deeply. You can't build an effective deterrent if you don't know what elephants respond to, how they make decisions, what information they use when they're navigating a landscape that increasingly has human settlements in it. He looked at how elephants moved, what triggered raiding behavior, and critically — how the social structure of the herd influenced those decisions. Because raiding isn't random. It's strategic, in the sense that elephants learn routes, learn timing, learn which areas are patrolled and which aren't. They're smart. You have to match that. Amara: And the solutions that come from this kind of behavioral understanding are so much more effective than blanket approaches. Things like bee-hive fences — because elephants have a documented aversion to bees — have shown real promise in parts of Africa. Chili-based deterrents. Early warning systems that alert communities to elephant movement so farmers can protect their crops non-lethally. None of these work unless you understand the animal you're trying to coexist with. None of them would exist without people willing to sit with elephants for years and ask: what are you doing, and why? Amara: The second story takes us somewhere surprising: Boston. There's an art exhibit currently on display that tells the story of a wild Indian elephant herd — through photography, documentation, art. It brings a specific herd, individuals with names and histories, into an urban gallery space and asks visitors to encounter them. Not as symbols. Not as endangered species statistics. As individuals. Amara: I love this for a lot of reasons, but mostly for this one: distance is one of the biggest barriers to conservation. Most people who live in cities in the Global North will never see a wild elephant. They'll never watch a matriarch read a landscape, never hear a low-frequency rumble move through the ground, never see what it looks like when a herd greets each other after a long separation — the spinning, the vocalizing, the temporal gland secretions running down their faces. That experience of being in the presence of elephants changes people. It has changed me, repeatedly, and continues to. Amara: Art can do some of that work. Not all of it — nothing replaces being there — but it can create a specific kind of encounter: here is a real herd, with a real matriarch, in a real landscape that is under real pressure. Here are their faces. Here is what their bonds look like. And now you know them. And knowing them makes it much harder to look away. Amara: That's the bet the exhibit is making. And honestly? I think it's right. Elephants earn people's care every time they get the chance to be known. The problem is, they don't always get that chance. So every gallery, every camera, every podcast, every long-form article that says — look, let me introduce you to someone — that matters. It adds up. Amara: Here's what I keep coming back to as I think about everything we've talked about today. Memory is not just a cognitive feat. It's a form of love. The matriarch who remembers where the water is during a drought is keeping her family alive with her mind. The elephant who returns to the bones of her mother is honoring something she cannot forget and does not want to. The researcher who spends years learning how a herd moves is saying: you matter enough to be understood. And the camera that keeps running, patient and quiet, so we don't miss a thing — that's a form of care too. Amara: Iain Douglas-Hamilton gave his life to that kind of care. Stephanie held her herd together with it. Linh Mai is performing it right now, probably, in front of a camera in Washington, picking up some enrichment object and thinking her own inscrutable thoughts. Amara: We are so lucky to share a planet with these animals. I don't take that for granted for a single day.
