As a tree-dwelling species, observing the re-introduced orangutans in Lamandau Wildlife Reserve is not always easy; with trees comes height and camouflage! Staff were therefore surprised when they noticed that Labetty was pregnant... her third time in six years!

Orangutan pregnancies are not dissimilar to that of humans; there is a gestation period of around nine months, changes occur both physically and mentally, and behaviours become less strenuous, with more time spent sleeping. Though Labetty’s behavioural changes have been far from peaceful!

Labetty was born in the wild in 2007 to ex-captive Lady Di, who had sadly suffered from a miscarriage the year before. 19 years later, Labetty is now pregnant with her third offspring. Suspiscions arose about her pregnancy from physical indications and altered behaviours in the female, but her enlarged abdomen confirmed the news – and we are delighted!
During Labetty’s pregnancy, her behaviour has changed in its own way. Typically indifferent towards the staff around her, paying them little to no attention, Labetty has been spotted chasing visitors of Camp Rasak, where she has been spending much of her time resting.

Our four camps in Lamandau Wildlife Reserve are only accessible by boat; the team arrive each morning by speedboat to begin their day of work. Last week, staff arrived as normal to the soundtrack of birdsong and the stirring of the orangutan carers who sleep at the camp. As they disembarked the speed boat, walking down the jetty towards the call of camp responsibilities, the speedboat driver Anto took a moment to secure the boat.

Soon after, with the boat in place, Anto followed the team down the jetty... but an angry Labetty soon emerged behind him! Less familiar with Anto, Labetty who had been sleeping beneath the jetty began had clambered on top and began to chase Anto! Luckily, Anto noticed her and managed to get clear... a warning nonetheless from the pregnant female!

It is difficult to confirm the reason for Labetty’s aggression, but it is likely due to mood changes associated with her behaviour. All the team are very excited for Labetty’s birth; this will be the sixth wild birth in the past year!
