Father takes over

A male orangutan has taken on an usual role at the Denver Zoo, after the death of the family’s matriarch last month. Nias, a Sumatran orangutan, died unexpectedly on Dec. 17 at age 32. Nias had two daughters — Hesty, who is 10, and Cerah, who is just two years old. On Tuesday, zoo officials said Cerah’s father, Berani, had “stepped up to the plate” and was taking care of the youngster.
