From plantation cage to conservation icon: Malaysia’s oldest sun bear Amaco dies at 33

SANDAKAN, June 27 — The Borneo Sun Bear Conservation Centre (BSBCC) is mourning the loss of its oldest resident, Amaco, who has died at the age of 33.

BSBCC founder and chief executive officer Dr Wong Siew Te took to sharing the news on Facebook “with a heavy heart” following Amaco’s passing on June 24.

He said Amaco’s health had been declining in recent weeks, with symptoms including poor appetite, weakness and difficulty standing.

He added that blood tests showed worsening kidney function and anaemia prior to his death.

According to Dr Wong, BSBCC keepers found that Amaco had died peacefully on the morning of June 24, during routine checks.

A post-mortem later revealed significant congestion in his lungs and liver, suggesting his circulation had been severely compromised.

The centre said these findings were consistent with age-related organ deterioration and chronic heart disease.

Amaco was 33 years old, making him the oldest sun bear under BSBCC care and well beyond the typical lifespan of wild sun bears.

Dr Wong said Amaco’s life before rescue had been difficult, as he spent 18 years confined in a small cage at a plantation.

Dr Wong said the experience had a lasting effect on Amaco, as he remained attached to his enclosure area even after being given access to forest habitats at BSBCC.

The biologist added that Amaco preferred staying close to familiar spaces where he felt safe, and keepers ensured he received care, enrichment and attention tailored to his comfort.

Describing his personality, Dr Wong said Amaco was “gentle, independent, and never afraid to let you know when he wasn’t impressed, often with a bark.”

Over the years, Amaco became a much-loved figure among staff, volunteers, visitors and supporters of the conservation centre.

BSBCC also thanked supporters of its adoption programme, saying their contributions helped provide Amaco with lifelong care, comfort and wellbeing.

Dr Wong ended its tribute saying, “Thank you, Amaco, for the memories, the lessons, and the joy you brought to us”.
