Cleveland Metroparks Zoo welcomes newborn François’ langur, an endangered monkey species, in primate family expansion
A new primate birth in Cleveland
Cleveland Metroparks Zoo has welcomed the birth of a baby François’ langur, a small, leaf-eating monkey species native to parts of China and Vietnam. The infant was born July 16 to parents Glora and Vinh, marking the pair’s second offspring at the zoo.
The newborn’s early weeks are expected to draw public attention because François’ langur infants are typically born a vivid orange. Over the following months, that bright coat gradually darkens to the black coloration seen in adults.
Where visitors may see the baby
At the time of the birth announcement, guests were able to view the infant with the troop on the second floor of The RainForest exhibit during regular zoo hours. The RainForest, a signature indoor habitat featuring thousands of plants and hundreds of animals from tropical regions, has been undergoing a major transition as part of a broader primate-focused redevelopment effort slated for completion in 2026.
Why the species matters
François’ langurs are listed as endangered, and their wild populations have declined over time due to habitat loss and other human-driven pressures. In modern zoos, births of threatened primates are typically managed with long-term population planning in mind, pairing animal welfare goals with genetic management for the species held in human care.
In practical terms, infant langurs also serve an educational role: they make it easier for visitors to observe family-group behavior, including close maternal care, troop dynamics and developmental milestones that are difficult to see in solitary species.
What’s known—and what remains unknown
Public information released about the birth has focused on the date, parentage and the infant’s distinctive early coloration. Details such as the baby’s sex and weight were not included in widely available public reporting at the time of the initial announcement.
Context: a period of high-profile births
The langur birth has come amid a recent stretch of notable animal arrivals at Cleveland Metroparks Zoo, including multiple high-profile species births reported during 2025. Zoo leaders have emphasized that visitors may not see every young animal daily, especially during colder weather months when animals may choose indoor or warmer areas.
Species: François’ langur (leaf monkey)
Birth date: July 16
Parents: Glora (mother) and Vinh (father)
Notable trait: infants are born bright orange and darken with age
In many primate species, newborn visibility and early development offer a rare window into social learning and family-group behavior—an important part of how zoos interpret conservation for the public.
