The Columbus Zoo & Aquarium on Aug. 24 announced the death of a 20-year-old orangutan.

Willie, a male Sumatran orangutan, had been diagnosed with chronic bronchiectasis for most of his life and died after an operation Aug. 23.

According to a news release from the zoo, Willie's disease gave him an "irreversible dilation of part of the bronchial tree" and periodic infections and pneumonia. Willie had undergone a bronchoscopy, which essentially is a lung washing, and cultures Aug. 23, when zoo staff noticed his condition worsening.

"He came out of the procedure and was in recovery but passed away overnight," the release stated.

Willie was born in a Texas zoo in 1991 and came to the Columbus Zoo & Aquarium in 2002.

Two other Sumatran orangutans, Sally and Tara, are on view at the zoo.
