Maryland Zoo to transition to all-male elephant herd - WBFF

Amara: Welcome back to The Long Memory — I'm Amara, elephant biologist, science communicator, and someone who has spent more mornings than I can count standing very still in the African bush, watching a matriarch decide the fate of her family. I'm so glad you're here. A quick thank you to our sponsors: Ada, who help organizations bring A I meaningfully into their workflows; Ago Consulting — that's "Ahh-Go" — silicon development experts working across the spectrum from A I to SoC; and Zen Semiconductor, an umbrella company with a remarkable portfolio right across the silicon industry. We are grateful for all three. Now — today on the show, we're going to talk about what happens when an all-male elephant group lives together and what science tells us about those bachelor herds; we're going to spend some time with the deep emotional architecture of elephant society, because there's a story there that I think will genuinely stop you in your tracks; and we're going to travel to Zambia, where a funding boost is changing the relationship between elephants and the communities who share land with them. Let's get into it. Amara: So — Mind of the Elephant. I want to start today by talking about bachelor herds, because the Maryland Zoo recently announced that they're transitioning to an all-male elephant group, and when I saw that story, my first thought wasn't controversy — it was actually: this is a really interesting window into a part of elephant cognition and social life that doesn't get nearly enough attention. We spend a lot of time — rightfully — talking about matriarchal herds, about grandmothers and daughters and aunties. But the bachelor herd has its own extraordinary social intelligence, and I think it deserves a closer look. Amara: In the wild, when young male elephants reach somewhere between ten and fifteen years old, they leave their birth family. Or rather — they're gradually nudged out. The matriarch doesn't kick them to the curb dramatically, it's more nuanced than that. They start spending more time on the periphery. They begin to test their independence. And eventually, they drift. They find other males. And what they build together is genuinely fascinating. Amara: For a long time, researchers — and honestly, the popular imagination — treated bachelor groups as kind of a holding pattern. A waiting room for males until they were old enough to mate. But the science has shifted significantly on this. Work coming out of researchers studying African and Asian elephant populations has shown that bachelor groups have their own social hierarchies, their own mentorship structures. Older bulls — we're talking males in their thirties, forties, sometimes fifties — they actively teach younger males. They model behavior. They seem to regulate the more volatile younger bulls, particularly those going into musth, that state of heightened testosterone and sometimes aggression. The presence of an older male in a bachelor group has been documented to measurably reduce disruptive behavior in younger ones. Amara: Think about what that means cognitively. It means these animals are reading each other, learning from each other, calibrating their own behavior based on social feedback over years. That is sophisticated social memory. An elephant doesn't just remember where the water is — he remembers who taught him how to be in the world. And that knowledge lives in the herd, transmitted not genetically but socially, generation to generation. So when a zoo thinks carefully about an all-male group — when they think about who the animals are, what their relationships are, what social dynamics they'll need — they're actually grappling with something very real. These aren't just big animals in the same enclosure. They're a society, with all the complexity that word implies. Amara: Heart of the Herd now. And I want to talk about something that sits right at the center of everything I find profound about these animals, which is the question of what elephants do when they lose someone. Amara: Elephant grief is — it's one of those things where the science has gradually caught up with what observers have been reporting for decades. Cynthia Moss, who has spent over fifty years studying the elephants of Amboseli in Kenya, documented some of the earliest and most detailed accounts of elephants returning to the bodies of the dead. Standing over them. Touching the bones with their trunks. Sometimes carrying bones a short distance. Returning to the same site years later. These aren't anecdotes — they're field observations logged systematically over decades. Amara: And researchers have since tried to understand what's actually happening neurologically and behaviorally. Elephants have a structure in their brain called the hippocampus — as we do — that's associated with memory and spatial navigation. But they also have highly developed temporal lobes, and their limbic system, the emotional processing center of the brain, is extraordinarily elaborate. The neural architecture is there for complex emotional experience. That doesn't mean they feel grief exactly as we do — I want to be careful about that — but it means the capacity for something grief-like is real, physical, documented in the structure of the brain itself. Amara: What moves me most, though, is not the individual grief — it's the communal response. When a matriarch dies, the effect on a herd can be seismic. Studies in Amboseli and in the Mikumi National Park in Tanzania have shown that herds become more erratic in their movements, more stressed in their behaviors, in the period after losing a matriarch. Because she wasn't just a leader. She was a library. Her knowledge — of dry-season water sources, of safe corridors, of which humans were dangerous and which were not — that knowledge dies with her unless it's been transmitted to the next in line. Memory is survival. And when it's gone, you feel the absence in the whole herd. Amara: There's an account I keep coming back to, documented by researchers in the field, of a young female elephant who lost her mother and was observed by her family group — observed, and then essentially adopted by an older female who had no biological relationship to her. The older female waited for the young one. Matched her pace. Kept her close during river crossings. You can call that instinct if you want. But at some point, the distinction between instinct and care starts to feel a little thin. Amara: And now — An Elephant-and-People Story. And today I want to bring you to Zambia, because there is real news here that I think deserves to be celebrated. Amara: The International Fund for Animal Welfare — IFAW — recently announced a significant funding boost for elephant conservation and sustainable community development in Zambia. And I want to unpack why that pairing of words matters so much: elephant conservation and community development. Together. In the same sentence. Because for a long time, those two things were treated as being in tension. You protect the elephants over here, the community is over there, and the community maybe loses farmland or livestock or sometimes worse, and the resentment builds, and the conservation fails. That model has a long and painful history. Amara: What's shifting — and what programs like this one in Zambia represent — is a recognition that you cannot save elephants without the people who live alongside them. Full stop. Zambia has extraordinary elephant populations, particularly in the Luangwa Valley and in areas bordering national parks. And those elephants don't stay neatly inside park boundaries. They move — sometimes through farms, sometimes through villages — because they're following ancient migration corridors that predate any boundary we've drawn on a map. Amara: The question of how communities and elephants share space is one of the defining conservation challenges of our time. And the emerging answers are genuinely hopeful. Beehive fences — actual fences made of beehives — have been shown to deter elephants in several African countries, because elephants have a documented aversion to bees. Chili-based deterrents. Early warning systems using radio communication or even seismic sensors that detect elephant footfall. These aren't glamorous technologies but they work, and more importantly, they give communities a tool. They give people agency. And when people have agency, when they feel like conservation is something happening with them rather than to them, the relationship changes. Amara: And there's another layer here that the research on tourism and elephant behavior helps illuminate. A study published recently in a peer-reviewed journal examined how wildlife tourism affects wild elephant behavior, and it found something important: that there are thresholds. There are levels of tourist presence and vehicle activity beyond which elephants show measurable stress responses — altered movement, increased vigilance, disrupted feeding. But below those thresholds, well-managed wildlife viewing can coexist with healthy elephant behavior. That matters enormously for the conservation economics argument, because sustainable tourism generates revenue that can flow back to communities, that can fund anti-poaching, that can make wild elephants worth more alive and present than absent. Amara: The Zambia funding story is a piece of that bigger picture. It's communities getting resources to implement conflict mitigation. It's elephant corridors being mapped and protected with local buy-in. It's the slow, hard, unglamorous work of building a future where there's room for both. And I find that genuinely moving — not because it's easy, but because people are doing it anyway. Because someone looked at a herd of elephants moving across a floodplain at dusk and decided that was worth fighting for. I understand that impulse completely. Amara: So that's what I've got for you today. A bachelor herd and the mentorship hidden inside it. A matriarch and the library she carries. Communities and elephants negotiating, slowly, painfully, hopefully, a shared future. What I keep coming back to, sitting with all of these stories, is that memory is the thread running through all of it. The bull who learned from the elder how to move through the world. The herd that feels the absence of the grandmother who knew where the water was. The community that remembers the elephant that crossed through at planting season, and decides — this time — to reach for the beehive fence instead. Memory is how any of us survive. Memory is how we belong to each other. This is The Long Memory, brought to you by Ada, Ago Consulting, and Zen Semiconductor.
