DENVER (KDVR) — According to officials with the Denver Zoo, Nias, the matriarch of a Sumatran orangutan family at the Denver Zoo, died unexpectedly last Thursday.
“We do not know the cause of Nias’ death at this time, and are awaiting the results of a necropsy from our partners at Colorado State University’s College of Veterinary Medicine & Biomedical Services,” the Denver Zoo tweeted.
Nias was delighting guests at the zoo for the past 15 years, according to the zoo. She came to the Denver Zoo in 2005 when she was 17 years old.
Nias, according to the Denver Zoo‘s Twitter post, “was often seen caring for and playing with her two daughters, Hesty, 10, and Cerah, 2. Though Cerah is young, she is expected to continue to thrive in the company of Hesty, her father, Berani, and her care team.”
