There's nothing cuter than a sun bear cub.

2021 was a very exciting year at the Bornean Sun Bear Conservation Centre. On May 20th, rescued sun bear Bintang unexpectedly gave birth to a scrawny infant with eyes glued shut and skin hanging in wrinkly folds.

This was the first ever captive birth at the Centre, and it certainly wasn’t planned.

Sun Bears are in Danger

Dr Wong Siew Te, the founder and director of BSBCC (and the hero of the Wildlife Wong series and Saving Sun Bears), was excited and anxious.

He and his team had never cared for a mother and cub before. To the contrary, most young cubs that arrive at the Centre are orphans.

Their mothers have been killed by poachers (Just like Damai's mother) in search of the lucrative gall bladder which is used in Chinese medicine.  

A Unique Chance to Observe

Bintang was an industrious mother, constantly grooming her prize and never letting her out of reach.

Wong and his team diligently observed and recorded the interaction between mother and offspring, delighting in watching such a rare occurrence.

Will the Sun Bear Cub Make it?

Their sense of wonder lasted a week. On day eight, the cub’s suckling reflex was weak, and they suspected her health was declining.

Wong made the difficult decision to remove the youngster from her mother for an examination. He knew all too well that Bintang may not accept her baby back.

The decision had been made just in time: the cub weighed just over 3.5kg and was suffering from hyperthermia. She had also lost the outside of her ears from over grooming.

The Cub is Optimistically Given a Name

The dedicated team at BSBCC went into hyperdrive. Despite being short staffed due to COVID-19, they organised into teams to feed the cub, (now named Luna), through the night in the hope they could save her life.

Their persistence was rewarded. After two months, little Luna started crawling. She was definitely a fighter!

Luna Learns to Climb

As soon as appropriate, Wong and his team introduced Luna to the rainforest and started to teach her bear skills like climbing and digging for termites.

She was a fast learner and Wong thinks there is a possibility she might be able to be released in the wild one day.

If so, she will be the first sun bear Wong has every released who was born in captivity.
