NANYUKI, Kenya — The mountain bongo has become the “ghost of the forest,” hard to spot amid the dense shrubs due to its ability to camouflage.

A critically endangered species, the animal is being slowly reintroduced into the wild by conservationists to increase the number of the rare antelope that are indigenous to Kenya’s forests.

The mountain bongo is a rare antelope known for its brown skin and distinct white stripes. With fewer than 100 individuals left in the wild, a conservancy based in Kenya is breeding them and slowly reintroducing them into the wild, with a target of 750 wild bongos by 2050.

Located on the misty slopes of Kenya’s highest mountain, Mount Kenya, and on the edge of the forest, the 1,250-acre Mount Kenya Wildlife Conservancy in the Nanyuki area has been restoring the survival instincts of zoo-bred bongos. They want to ensure the animals can feed without human assistance, escape from predators, and build a strong immunity against diseases in the wild.
