The Phoenix Zoo is used to hosting birthday parties, but this one was a little different.
Duchess the orangutan turned 50 on Saturday, and the zoo treated her to gifts, an ice cake filled with fruit and a rendition of “Happy Birthday” by hundreds of zoo visitors.
Her keeper, Bob Keesecker, said Duchess didn’t seem too stressed about the milestone.
“I told her it was her birthday today and she didn’t seem to be overly concerned about it,” he said. “I made sure her hair looked good before she went out.”
Keesecker said Duchess has quite a sweet tooth and worked pretty hard to get to the fruit in the ice cake.
Zoo officials say Duchess is the nation’s oldest captive Bornean orangutan, and is now 10 years older than the 40-year life expectancy of orangutans in the wild.
