DENVER — The Denver Zoo’s youngest Sumatran orangutan turns 1 year old on Monday.
The public is welcome to Cerah’s birthday celebration, which begins at 10 a.m. in the orangutan habitat in the Great Apes section of the zoo.
Cerah and the rest of her clan will enjoy treats and presents Monday morning.
Cerah, which means “bright” in Indonesian and is regularly used to talk about sunshine, was the fourth orangutan born at Denver Zoo and the second baby for her mother, Nias, whose first baby, Hesty, was born in 2010.
The worldwide population for Sumatran orangutans hovers around 9,200. Their survival is threatened by habitat loss. The animals are classified as critically endangered on the International Union for Conservation of Nature Red List of Threatened Species. They are only found on the island of Sumatra in Indonesia.
