Fresno Chaffee Zoo Mourns Death Of Orangutan Siabu

The Fresno Chaffee Zoo is mourning the loss of their 31-year-old orangutan named Siabu.

In February Siabu was diagnosed with oral cancer, according to ABC30.

Although she had undergone chemotherapy and several surgeries, doctors discovered that the tumor had advanced too far.

According to the doctors, Siabu was in discomfort and any further treatment wouldn't have helped her.

Ultimately, the zoo decided to humanely euthanize her.

This is second orangutan death at the Fresno Chaffee Zoo this year.

In April, the zoo lost a 49-year-old female orangutan named Sara.

The two orangutans arrived at the zoo together and the zoo said Sara acted as a surrogate mother to Siabu.

In an official statement, the zoo said "Siabu came to Fresno Chaffee Zoo in 2001 from Audubon Zoo in New Orleans. She was part of Fresno Chaffee Zoo for almost 20 years and gave birth twice, to female Ndari in 2010 and male Hantu in 2018. Animal care staff remember Siabu as sassy, tenacious and feisty. She was known for investigating any enrichment items and solving any puzzle she was given. She was a devoted mom to both her offspring and built the best nest every night where she would sleep and cuddle with them."
