Mountain Bongos Resurface Where They Were Thought Gone Forever

When a species vanishes from the wild, hope fades fast. But a trail camera in a remote Kenyan forest just captured something conservationists had nearly given up on seeing: proof that mountain bongos still roam beyond their last known stronghold.

For years, the Mountain Bongo Project tracked these elusive African forest antelopes to just four isolated pockets, with the Aberdare mountains becoming their final refuge. Then, roughly 200 kilometers away in Maasai Mau—a region where bongos hadn’t been confirmed in living memory—camera traps caught images of three individuals: a mature male first spotted in 2018, plus a young male and young female that appeared more recently. The moment the team reviewed those photos was electric. As Oscar Dyer, Director of Operations for the Mountain Bongo Project, put it: the excitement in camp was unbelievable.

What makes this discovery so significant isn’t just the sighting itself—it’s what it signals about persistence and hidden populations. Recent AI surveys by Chester Zoo estimated only 28 bongos in the Aberdares, though the Mountain Bongo Project believes the true number could be closer to 40. These Maasai Mau individuals suggest the species may be more widely distributed than anyone realized, and that dedicated field work by local Maasai rangers—who use generations of ecosystem knowledge—can still uncover hidden survivors. Dr. Tommaso Sandri, a Chester Zoo conservationist who helped identify the mature male years ago, had theorized that if one bongo could remain hidden, others likely could too. He was right.

Bongos face a grim calculus: they’re drawn to the same rich volcanic soil and water sources that farmers and loggers want. Habitat destruction has been relentless. Yet the species isn’t extinct. About 900 bongos live in zoos and sanctuaries worldwide, and recent translocations—including four European-born males sent to Kenya—are building genetic diversity for potential reintroduction. The Mount Kenya Wildlife Conservancy and organizations like Chester Zoo are treating the Maasai Mau population as a vital genetic reservoir for long-term survival.

This isn’t a story of rescue yet. It’s a story of a species on the edge, held up by collaboration between researchers, zoos, local communities, and rangers willing to work in Kenya’s most inaccessible forests. The mountain bongo is not beyond saving, but it requires sustained commitment and resources. One trail camera image doesn’t guarantee a future—but it proves that giving up too soon would be a mistake. As Dr. Tommaso Sandri reminded us: their presence makes the forest more magical, and the world would be poorer for their loss.
