Leopards and mountain gorillas share the same forest in Bwindi Impenetrable National Park, and while adult gorillas — particularly silverbacks — are largely immune to leopard predation, infants represent a genuine vulnerability. The documented cases of leopard attacks on gorilla groups in Bwindi are rare but real, and each has generated significant research interest. The case of the Rushegura infant in 2017 — a young female who survived a leopard attack that would have killed most animals her size — is one of the most closely studied examples of both gorilla group defence and mountain gorilla infant resilience.
The Vulnerability of Gorilla Infants
Mountain gorilla infants are born at approximately 1.8 kg and reach only around 8 kg by their first birthday. During this period they are entirely dependent on their mothers for protection as well as nutrition. A mother gorilla will hold her infant continuously for the first months of life and maintain close physical contact for years afterwards. Despite this protection, infants remain the most physically vulnerable members of a gorilla group, and leopards — Africa’s most adaptable large predator — are capable of making rapid, targeted attacks that can succeed before adult gorillas can respond.
The Rushegura family is one of Bwindi’s most studied habituated groups. Based at Buhoma sector, they have been receiving trekking visitors since the mid-1990s and are monitored continuously by UWA rangers and researchers. The incident in October 2017 occurred during a period when the group was resting in dense forest approximately two hours from the trekking base.
The Attack and Immediate Aftermath
The attack was not witnessed directly — it occurred in dense undergrowth and was detected by the ranger monitoring team through the alarm vocalisations of the adult females. By the time the rangers reached visual contact with the group, the leopard had withdrawn and the infant — a four-month-old female born to one of the Rushegura group’s younger adult females — had sustained lacerations to her back and right shoulder.
The silverback’s response was documented by the rangers: he had moved rapidly toward the disturbance and his presence had apparently caused the leopard’s retreat. Adult male gorillas will charge and physically confront leopards when infants or females are under threat, and the silverback’s movement toward the attack site was consistent with this documented protective behaviour.
The Gorilla Doctors Intervention
The Gorilla Doctors team was contacted within hours of the incident. Their assessment of the infant found that while the lacerations were significant — one wound on the shoulder reached the muscle layer — no vital structures had been damaged and the infant was nursing and maintaining normal temperature. The team made the decision to monitor rather than intervene immediately, observing that the mother was keeping the infant calm and that the wounds were not actively bleeding.
Over the following ten days the team conducted daily monitoring of the infant. The mother’s care was exceptional — she restricted the infant’s movement, allowing the wounds to close, and the wounds showed no signs of infection. On day twelve the Gorilla Doctors team assessed the infant as not requiring direct medical intervention. The wounds healed over the following weeks, leaving scars that researchers used to identify the individual in subsequent monitoring.
The Infant Today
The female gorilla who survived the 2017 attack is now a juvenile member of the Rushegura group. Trekkers who visit the group in 2027 may observe her — identifiable to experienced guides by the scarring on her right shoulder — as an active, healthy member of a family that continues to be one of Bwindi’s most visited. Her survival is a product of her mother’s care, the Gorilla Doctors’ expertise, and the monitoring infrastructure that gorilla trekking revenue funds. The gorilla permit costs $800. Some of what that pays for is the system that kept her alive.
