Summary:
DENVER, CO – A beloved 32-year-old Sumatran orangutan was euthanized s at the Denver Zoo Conservation Alliance on Monday.
In 2024, Berani was diagnosed with kidney disease, which progressed to late-stage kidney failure earlier this year, meaning his organs could no longer function on their own, the zoo said. Recent bloodwork showed that he had entered end-stage kidney failure, with a noticeable decline in health and quality of life.
Berani came to Denver from Audubon Nature Institute in 2017 on a survival plan and breeding recommendation.
