Every new birth among endangered great apes represents a vital conservation success story. However, this particular arrival carries an extraordinary resonance. The mother, a gorilla named Lulingu, was once isolated from her natural mountain habitat entirely, rescued from the illegal wildlife trade as an infant, and guided through an extensive rehabilitation and rewilding journey. The newborn’s father is a wild silverback residing on Mount Tshiaberimu, confirming that Lulingu has not only adapted to her ancestral environment but has also fully integrated into the existing wild population.
Lulingu’s journey back to the wild began in earnest at the end of 2024, when she was moved from the GRACE sanctuary for rescued gorillas in North Kivu province to Virunga. She was accompanied by three other female gorillas—Mapendo, Ndjingala, and Isangi—marking the culmination of a rigorous, multi-year rewilding initiative. This complex, collaborative undertaking was led by the Gorilla Rehabilitation and Conservation Education (GRACE) center, Virunga National Park, and local communities, with vital support from Gorilla Doctors and Re:wild.
The roots of this success story stretch back decades, or rather, to the earliest days of Lulingu’s life. Rescuers recovered her when she was a mere 18 months old after she was torn from her family and funneled into the illicit wildlife trade. Upon her arrival, she earned the distinction of being the youngest orphaned gorilla ever brought to GRACE, which remains the only sanctuary in the world dedicated specifically to rescued eastern lowland gorillas.
During her formative years, GRACE provided Lulingu with around-the-clock, specialized care. Eventually, another resident gorilla named Pinga stepped in as her surrogate mother, welcoming the traumatized orphan into a larger, surrogate gorilla family group at the sanctuary. That family eventually formed the nucleus of the four-female cohort that would make the unprecedented journey back to the wild.
For the conservationists who watched Lulingu grow from a frightened, orphaned toddler into a resilient adult, seeing her embrace motherhood is both emotional and deeply encouraging.
“This is a milestone for the gorillas,” said Katie Fawcett, executive and science director of GRACE Gorillas. “They’ve adjusted to living in the wild extremely well so far, but raising an infant in the wild can be a challenge even for experienced mothers. We’re cautiously optimistic that Lulingu will navigate motherhood well and that the baby will continue to survive. No matter what happens, this is another historic first for eastern lowland gorilla conservation.”
Beyond the emotional weight of Lulingu’s personal triumph, the birth serves a critical ecological purpose. It represents a vital step toward the broader conservation project’s central goals: injecting much-needed genetic diversity into the small, isolated gorilla population living on Mount Tshiaberimu.
Ever since the four females were released into the wild in December 2024, a dedicated gorilla monitoring team has tracked the family group closely. Field researchers have documented the females mating with the dominant silverback. To track these developments non-invasively, the monitoring team has collected urine samples from fresh leaves found in the gorillas’ wake, utilizing standard human pregnancy tests to detect elevated levels of pregnancy-related hormones.
The health of the reintroduced group has been a source of continuous relief for the veterinary teams overseeing the project.
“None of the four females have required veterinary treatment for illness or injury since being rewilded—the outcome we always hope for,” said Dr. Cedric Kibengo, a field veterinarian with Gorilla Doctors who has been involved in the reintroduction effort from the start. “With the arrival of Lulingu’s infant, we now have one more ‘patient’ under our care, and both mother and infant are healthy and doing well.”
Lulingu has already cleared numerous hurdles since her return to the wild, successfully navigating a completely unfamiliar habitat, a new foraging diet, and a complex social hierarchy. These early successes have instilled profound confidence in the monitoring team as she faces yet another daunting milestone: rearing her first offspring.
“We have seen her nursing, cradling, and playing with the baby,” reported Benoit Ishaba, a park ranger and the head of gorilla monitoring on Mount Tshiaberimu. “The other young gorilla in her group has shown interest in the baby, and Lulingu has been very patient with him.”
For scientists and wildlife researchers, the birth offers a rare, invaluable window into the behavioral dynamics of a rewilded eastern lowland gorilla experiencing motherhood for the first time. Observers are closely studying how the reintroduced females respond to and interact with the newborn within the established social group.
Gorilla pregnancies typically last between eight and nine months. Given the monitoring team’s observations of the group’s mating habits, conservationists note that at least one of the other rewilded females may also be pregnant, raising hopes for additional births in the coming weeks and months.
“Each healthy infant represents more than an addition to the population—it is a sign of resilience, recovery, and what is possible through long-term care, collaboration, and targeted protection,” said Mary Brown, Re:wild’s Africa program lead.
As the newborn grows, partner organizations plan to maintain their vigilant tracking of Lulingu, her infant, and the wider family group, ensuring that this vulnerable population continues to find its footing and thrive within the protected expanse of Virunga National Park.
