Death and birth are two certainties for all living beings on earth. Naturally, in this circle, for every life that passes another one begins. We are very excited to share the news that we will be welcoming three new orangutan infants into Lamandau Wildlife Reserve this year! However, at the same time, with deep sorrow, we announce the death of Lego, the infant male orangutan of Labetty.
Lego and Labetty in December 2024
Sugih, Acuy and Amina are all expected to give birth later this year. The former two are ex-captive individuals now living in the wild, whereas the latter, Amina, is Acuy’s first offspring. This means that as well as her own child, Acuy will be welcoming her second grandchild from Amina.
Lego was Labetty’s second offspring. Born on 11 June 2024, he has been living under the care of his mother in the protected reserve. Many of you may recognise Lego from his recent endeavours, climbing independently for his very first time. Sadly, on 11 March 2025, Lego passed away, potentially with drowning as the cause.
The three expecting orangutan mothers
Acuy
Acuy with previous offspring
Released into the reserve in 2006, Acuy is now approximately 30 years old and has already had three offspring in her lifetime: Amina, Ariel and Arul. Prior to her pregnancy, Acuy was seen with the Andy, a younger male living in the reserve, and Tole, a dominant male. Observations indicate that despite Andy’s lower status, he was in fact the male that mated.
With Acuy being a regular visitor to the feeding site at Camp Rasak - where fruit is provided to ex-captive orangutans now living in the wild at times of low fruiting in the forest – staff soon noticed physical signs of her pregnancy in the form of swollen genitals. Following closer veterinary observations, it is predicted that Acuy will give birth in September 2025.
Amina
Amina and her first offspring, Albie
Amina, born in the wild in 2007, has long been living independently from her mother Acuy. Amina bore her first offspring, Albie, in 2019, and has since been teaching him to survive independently. Aside from foraging and climbing, Albie has been seen helping his mother to build a nest for the pair to sleep in at night. As orangutans build a new nest each day, this regular practice for Albie is preparing him for when the time comes to live alone.
When orangutan mothers give birth to a new infant, the older, now adolescent offspring leaves to start its own life due to food scarcity in the forest. It is common for the individual to stay close by, however, keeping a short distance and sleeping in their own nest. Already, Albie is venturing considerable distances from his mother, though often cries when Amina is out of site. No doubt, he will soon learn that he will have to share his mothers attention when her new offspring arrives!
Sugih
Sugih post-release in Lamandau Wildlife Reserve
Staff recently delivered news that in Camp Buluh, Lamandau Wildlife Reserve, ex-captive Sugih released into the wild in 2016, is also showing indications of pregnancy. This will be her first time being a mother. Having learnt all the skills to survive whilst in the soft-release programme - our rewilding project for orphaned orangutans - we are confident that Sugih has all the knowledge necessary to successfully rear her offspring.
As we often say, it is wonderful to see orangutan populations thriving in the safety of a protected area. Through tragedies and complications, it is moments of conservation successes that remind us of the importance of protecting this critically endangered species and their vital rainforest habitat.
