Denver Zoo is grieving the loss of one of its most beloved animals, Berani, a 32-year-old Sumatran orangutan who captured hearts across the world. On Monday, zoo officials announced that Berani had been humanely euthanized after entering end-stage kidney failure. His passing marks the end of an inspiring journey that touched thousands of visitors, animal lovers, and conservationists alike.
Berani’s Remarkable Role as a Single Dad
Back in 2020, Berani made headlines when he stepped into the rare role of a single father for his infant daughter, Cerah. After the unexpected death of his mate, Nias, the Denver Zoo witnessed a touching story of love and responsibility.
Male orangutans in the wild are typically not known for caregiving, but Berani proved otherwise. He became a gentle, patient, and nurturing parent, often seen holding Cerah in his arms, comforting her, and giving her the security she needed. Even as Cerah grew older and more independent, she often sought the safety of her father’s embrace.
According to the Denver Zoo Conservation Alliance, Berani’s story was unique: “Male orangutans rarely take on caregiving roles, but Berani became a devoted, patient, and caring father figure.” This heartwarming act inspired global admiration and showed how deeply connected animals can be to their families.
Welcoming Another Daughter
Berani’s journey as a father continued when he welcomed another daughter, Siska, in 2023 with his mate Eirina. The announcement of Siska’s paternity became even more memorable when talk show host Maury Povich joined in to confirm Berani as the proud father.
This playful moment highlighted not only Berani’s importance to the Denver Zoo but also the joy he brought to people everywhere. His role as a dad symbolized hope for the future of his endangered species.
Struggle with Kidney Disease
In 2024, Berani was diagnosed with kidney disease, a condition that is unfortunately common among orangutans. By early 2025, his illness had progressed to kidney failure. Despite medical treatments and dedicated care, his health began to decline.
Recent bloodwork and visible signs of fatigue showed that Berani’s quality of life was rapidly diminishing. After careful consideration, the Denver Zoo’s animal care and health teams made the compassionate decision to euthanize him, ensuring he did not suffer further.
In their official statement, the zoo shared: “When recent bloodwork and a noticeable decline in his health showed that his quality of life was diminishing, our teams made the compassionate decision to humanely euthanize him.”
Life at Denver Zoo
Berani arrived at the Denver Zoo in 2017 from the Audubon Nature Institute in New Orleans, Louisiana. His transfer was part of the Association of Zoos and Aquariums’ Species Survival Plan, a program aimed at preserving endangered species like the Sumatran orangutan.
During his years in Denver, Berani became a symbol of strength, curiosity, and resilience. Staff members remember him as playful and deeply intelligent. He often invited caretakers to play, even while they were busy with other tasks. Sometimes, he whistled just to get their attention.
A Personality That Touched Hearts
Animal care specialists shared emotional tributes to Berani after his passing. Christa Klein, a longtime caretaker, recalled:
“I’ll never forget when he’d look into your eyes, really seeing you, then find something to gift you and smile. Berani reached people across the world, not only inspiring them to care about him and his family but also to care about orangutans in the wild.”
Another caretaker, Kirstin Prunchak, described Berani’s playful side. He loved using combs to make music, painting on walls, and even playing with hoses. Despite his illness, he showed extraordinary bravery. “His strength was never more apparent than in his final months,” she said.

Legacy of Compassion and Conservation
The Denver Zoo has emphasized that Berani’s story will continue to inspire future generations. Information collected during his postmortem exam will contribute to better orangutan care and global conservation efforts.
Officials expressed their grief but also highlighted the lessons Berani leaves behind:
“Our campus will never feel quite the same without him, but his story will continue to inspire compassion for orangutans and conservation worldwide.”
Importance of Orangutan Conservation
Berani’s life and story are not just about one remarkable animal—they are also a reminder of the urgent need to protect Sumatran orangutans, a critically endangered species. Habitat loss, poaching, and deforestation have left fewer than 14,000 Sumatran orangutans in the wild.
By caring for animals like Berani and supporting breeding programs, places like the Denver Zoo play a vital role in preserving endangered species and educating the public about their importance.
