Denver Zoo Marks Gibbon's 30th Birthday With Epic Bash

Staff at Denver Zoo in Colorado last week threw a party to celebrate Vinh the gibbon’s 30th birthday.

Footage shared by the zoo shows staff singing Happy Birthday to Vinh, a white-cheeked gibbon, in the zoo’s Toyota Elephant Passage.

The clip shows Vinh inspect a tree decorated in ribbons as she pokes at her birthday cake.

“As of today, Vinh is officially Thirty, Flirty, and Thriving, and we couldn’t let her enter this new decade without a surprise birthday party to celebrate,” the zoo wrote on Facebook. Credit: Denver Zoo via Storyful
