When it comes to unforgettable primate encounters, few experiences rival a sighting of the mandrill (Mandrillus sphinx). Known for their vivid colours and striking appearance, mandrills are also one of the most social primates in the world — and Gabon is their stronghold.
The world’s largest Primate hordes
In Gabon’s Lopé National Park, mandrills have been recorded forming groups of more than 600 individuals, sometimes even approaching 800. These vast “hordes” are a spectacle of movement and energy, as adults, youngsters, and dominant males move together through the rainforest.
Diet and daily life
Mandrills are opportunistic feeders. In Gabon, studies show they eat a mix of fruits, seeds, insects, and leafy vegetation — carefully selecting what they need from the forest floor and understory.
Conservation Status
Mandrills are currently listed as Vulnerable on the IUCN Red List. Their biggest threats include hunting for bushmeat and habitat loss due to logging and agriculture. Gabon plays a vital role in their survival, hosting important conservation programs, from monitoring hordes in Lopé National Park to reintroduction projects in the Lékédi Park.
Why It Matters
Every mandrill sighting is a reminder of the fragility and richness of Central Africa’s forests. Protecting them means not only safeguarding this incredible primate but also conserving one of the planet’s most biodiverse ecosystems.
