Can I Do Gorilla Trekking on a Budget?
June 24, 2025Bwindi Ground Nesting Chimpanzees discovered!
“We thought we knew the forest—until the ground moved.”
In a thrilling twist that has stunned primatologists and delighted conservationists, researchers have confirmed the presence of Bwindi ground nesting chimpanzees in the northern sector of Bwindi Impenetrable Forest National Park. Long known as the crown jewel of gorilla trekking, Bwindi now claims another rare behavioral wonder—a troop of chimpanzees that build their beds on the forest floor, not in the canopy above.
This behavior is extraordinarily rare, and its discovery in Bwindi opens up new scientific questions, ecotourism opportunities, and a renewed sense of awe for Uganda’s biodiversity.
How the Discovery Unfolded: The Great Ape Census
In May 2025, the Uganda Wildlife Authority (UWA), in partnership with the Jane Goodall Institute, launched a landmark biodiversity mission—a comprehensive population census of gorillas and chimpanzees in Bwindi Impenetrable Forest. While Bwindi is world-renowned for hosting nearly half of the planet’s remaining mountain gorillas, its chimpanzee population has long remained under-studied, largely due to the challenging terrain, dense vegetation, and elusive nature of the primates.
Over 60 trained field researchers and conservation rangers—70% drawn from UWA—began sweeping through the forest in a structured, scientific effort to collect data across over 40 grid-marked sectors. Using GPS devices, mobile data collection apps, camera traps, and fecal sampling, the teams trekked through rugged hills and river valleys for miles each day. Their goal? To gather ecological evidence of great apes in areas previously unexamined, mapping nest locations, identifying droppings for DNA, and assessing threats from human activity.
It was during these field surveys that researchers encountered something astonishing: multiple well-built chimpanzee nests on the forest floor, carefully arranged from branches, twigs, and leaves—built not up in the trees, as is typical, but directly on the ground.
The first sighting raised eyebrows. The second caused hushed speculation. By the time several of these ground nests were documented across multiple transects, it became clear: this was not an isolated anomaly. Bwindi’s chimpanzees were doing something highly unusual.
Why Bwindi Ground Nesting Chimpanzees Are So Unique?
The Bwindi ground nesting chimpanzees of Bwindi Impenetrable National Park stand out not only because of their remote, forested home but because of the fascinating and unusual behaviors they exhibit. These primates are rewriting what we thought we knew about chimpanzee traditions, adaptability, and ecology. Here’s why this population is truly exceptional:
1. Ground Nesting Behavior – A Cultural Enigma
Most chimpanzees instinctively build their nests high in the forest canopy, where they’re safe from predators, parasites, and weather hazards. But the chimps of northern Bwindi defy this norm.
Researchers have found repeated evidence of purposefully constructed nests on the forest floor—a behavior considered extremely rare and even puzzling in the primate world. What makes this particularly intriguing is that ground nesting here is not occasional; it’s habitual.
This points to the existence of a localized cultural tradition, where young chimps may be learning from elders that ground sleeping is safe, effective, or preferable.
Such behavior is not hardwired—it’s socially acquired. Just as humans form regional customs or languages, chimpanzees can develop community-specific traditions that are passed down through generations. In this case, the Bwindi chimpanzees may have carved out a unique survival tactic that challenges what scientists thought was a universal chimpanzee instinct.
2. Geographic Isolation – Nature’s Living Laboratory
Unlike the larger, better-studied chimpanzee populations in places like Kibale Forest or Budongo, the Bwindi group is relatively small and geographically isolated. The dense terrain, steep ridges, and limited human access have likely kept this Bwindi ground nesting chimpanzees population somewhat cut off from other chimp communities in western Uganda. This kind of isolation often leads to behavioral divergence, where animals adapt to their unique surroundings and form distinct patterns over time.
It’s the same way human cultures evolve differently across continents or even regions. In Bwindi’s case, the rugged, secluded landscape may have created the perfect conditions for independent cultural evolution among chimpanzees—allowing ground nesting and other unknown behaviors to flourish without influence from neighboring populations.
3. An Unstudied Group – Secrets Waiting to Be Discovered
Bwindi is globally famous for its mountain gorillas, which have been the focus of decades of research, habituation, and tourism. In contrast, the park’s chimpanzees have remained largely unhabituated, elusive, and under-studied. The forest’s thick vegetation and lack of established chimp tracking routes have made direct observation difficult—until now.
The recent discovery of Bwindi ground nesting chimpanzees is one of the first significant glimpses into the hidden lives of Bwindi’s chimpanzees. There’s a sense of scientific excitement, as researchers believe this population may hold even more undiscovered behaviors, social structures, or dietary patterns unique to their environment. In many ways, studying them is like opening a long-sealed time capsule, revealing a world of behaviors untouched by modern disturbance.
4. Coexisting with Mountain Gorillas – A Rare Primate Overlap
Few places on Earth boast such a dense concentration of great apes in one habitat. In Bwindi, chimpanzees and endangered mountain gorillas share the same forest space—something exceedingly rare in the animal kingdom. Most primates either avoid or are separated by territory, but here, their ranges overlap, offering researchers a unique opportunity to observe how these two intelligent species navigate shared resources, interact, and coexist.
Do they compete for food? Do they avoid each other? Could they influence each other’s behaviors? These are questions that scientists are now eager to explore. This inter-species coexistence in a protected, relatively undisturbed ecosystem could reveal valuable insights into primate ecology, cooperation, and conflict.
Where Else Can You Track Chimpanzees in Uganda?
While the discovery of Bwindi ground nesting chimpanzees in Bwindi has thrilled the scientific community, it’s important to note that these apes are not yet habituated to human presence. That means they’re still shy, untracked, and not suitable for tourism—yet. For travelers hoping to witness Uganda’s chimpanzees in the wild, several other destinations offer accessible, unforgettable, and ethically responsible encounters.
Uganda is one of the most primate-rich countries in the world, and tracking chimpanzees here ranks as one of the top wildlife experiences in Africa. Here’s where you can see them up close:
Kibale Forest National Park – The Primate Capital of the World
If you’re dreaming of walking among chimpanzees, Kibale Forest is your best bet. This sprawling tropical rainforest is home to over 1,500 individual chimpanzees, many of which have been carefully habituated for tourism and research. Visitors can embark on standard chimpanzee tracking treks, usually lasting 2–4 hours, or go deeper with a Chimpanzee Habituation Experience (CHEX)—a full-day adventure shadowing researchers as they follow chimps from nest to nest.
Kibale isn’t just about chimpanzees—it’s also home to 13 other primate species, including red colobus monkeys, grey-cheeked mangabeys, and L’Hoest’s monkeys, making it a true paradise for primate lovers.
Budongo Forest – Wild Chimps & Waterfalls
Part of the greater Murchison Falls Conservation Area, Budongo Forest lies in the Kaniyo Pabidi sector and is the largest natural forest in Uganda. It boasts a significant population of wild chimpanzees, many of which have been habituated through long-standing research projects.
What sets Budongo apart is the diversity of experiences it offers. Chimp tracking here can be combined with a safari in Murchison Falls National Park, famous for its dramatic waterfall, the Nile boat cruise, and big game like lions, elephants, and giraffes. The forest itself is rich in mahogany trees, birdlife, and butterflies—making every step of the trek visually rewarding.
Kyambura Gorge – The Valley of the Apes
Hidden in the far eastern corner of Queen Elizabeth National Park, Kyambura Gorge is often described as one of Uganda’s most scenic and surreal landscapes. Carved by ancient tectonic activity, the gorge is a deep, forested chasm that contrasts sharply with the surrounding savannah.
Here, a small but habituated community of chimpanzees lives in a world of its own—accessible only through a steep descent into the gorge. Though sightings can be less reliable than in Kibale or Budongo, the trek is absolutely thrilling. You’ll walk beneath towering fig trees, hear the calls of vervet monkeys echoing through the gorge, and possibly spot the elusive chimps swinging across the canopy or foraging on the ground.
Why You Should Visit Bwindi Now
Nestled in the misty highlands of southwestern Uganda, Bwindi Impenetrable National Park has long been a crown jewel of African ecotourism—famed for its rare population of mountain gorillas and its ancient, biodiversity-rich rainforest. But now, something extraordinary is happening within its tangled undergrowth, and the world is only just beginning to take notice.
A new discovery—ground-nesting chimpanzees—has placed Bwindi at the center of one of the most exciting wildlife stories of the decade. This hidden behavior, observed during the latest national chimpanzee census, has not only surprised researchers but also elevated Bwindi’s importance as a hotspot for primate evolution, behavior, and conservation.
This is why now is the moment to go—before the rest of the world catches on.
- A Rare Glimpse into Uncharted Primate Behavior
Most people visit Bwindi to experience the once-in-a-lifetime thrill of standing face-to-face with a gorilla family. But imagine this: while you’re tracking gorillas, a chimpanzee could be watching you quietly from a nest—not in the trees, but on the forest floor.
This isn’t normal chimpanzee behavior. Typically, chimps sleep high up in trees for safety from predators. So the recent discovery of multiple ground nests—carefully built and repeatedly used—suggests a cultural tradition, something likely passed down within this unique population. This behavior is incredibly rare and has been documented in only a few other regions in Africa, like parts of the Congo Basin.
Bwindi is now the first place in Uganda where this has been confirmed.
Researchers believe this behavior could reflect a local adaptation, a social tradition, or even a glimpse into how early human ancestors may have lived. It’s a window into evolution in real time—and it’s happening right now, in Bwindi.
A Park of Two Great Apes
Bwindi is already one of the only places on Earth where mountain gorillas and chimpanzees coexist in the same ecosystem. While many travelers come for the gorillas, they are only beginning to understand the deeper ecological richness the park offers.
The chance to walk through a forest where two of our closest living relatives live side by side, each with their own complex social structures and survival strategies, is something you simply can’t experience anywhere else at this scale. And unlike more developed national parks, Bwindi remains raw, mysterious, and unfiltered by mass tourism.
As chimpanzee behavior continues to be studied and revealed, visitors will one day say, “I was there when it was first discovered.”
Not Yet Overrun by Tourism
While other chimpanzee tracking hotspots in Uganda—like Kibale Forest—are well-developed and see large numbers of tourists, Bwindi’s chimpanzees are not yet habituated. This means they are wild, elusive, and untouched by human interference. It also means that now is the best time to visit if you want to experience the park’s primates in their most authentic state.
In the coming years, these chimps may be habituated for research and tourism purposes, and while that will offer more reliable sightings, it will also change the dynamic forever.
Traveling now means encountering a Bwindi that is still full of mystery.
Support Conservation at a Crucial Moment
Bwindi is a UNESCO World Heritage Site and a global priority for conservation. By visiting now, especially in light of these groundbreaking discoveries, you are not only enjoying a profound experience—you are also directly contributing to the protection of its wildlife.
Tourism revenue supports ranger patrols, local communities, anti-poaching efforts, and scientific research. With chimpanzees newly confirmed in the park, funding and attention will be crucial to ensure that these behaviors are preserved—not lost to deforestation, human-wildlife conflict, or climate pressure.
Be Among the First to Tell the Story
When you return home and tell people you saw where gorillas and ground-nesting chimpanzees live together, they’ll probably ask, “Wait—chimpanzees nest on the ground?” And you’ll get to say, “Yes. In Bwindi. I saw it with my own eyes.”
Being one of the first travelers to visit Bwindi after this revelation means you are witnessing history in the making. This isn’t just wildlife tourism—this is participating in a scientific and ecological breakthrough.
