Recently, three members from our PRM team in Nles Mamse Camp – Jani, Usup, and Rizal – located Leonie and Teresa around Transect 7. These two female orangutans were released in September and December 2015 respectively and it was great to have the chance to record behavioural data on them in the Kehje Sewen Forest: Both have covered an extensive range since their release, and have been difficult to track.
The team arrived at Transect 7 early and quickly spotted Leonie waking in her nest. She was hungry, and immediately climbed down from her nest to start feeding on the forest floor.

As the team were observing Leonie, Teresa arose from her nest located nearby. Teresa joined Leonie and the two fed together.

Shortly after, Leonie and Teresa climbed a tree and started moving through the forest together, taking their time to rest and eat forest fruits along the way. The team had to keep their distance, as both females expressed displeasure when they became aware of human presence.
The two actively moved through the trees, only descending occasionally to eat different food items. The pair kept moving toward the hills as the sky began to darken: Following them, the fading light and challenging terrain forced the team to end data collection for the day. But it was great to have observed these two magnificent females thriving in the forest.
The next day, the team caught up with the two again. As on the previous day, the two did everything together.
Compared to other orangutans released in 2015, Leonie and Teresa have continued to range widely across the Kehje Sewen Forest. They appear to be in great health and skilful foragers.

BOS Foundation is dedicated to Bornean orangutan conservation and one of our tasks is to successfully reintroduce orangutans to safe natural habitat where they can establish new viable populations. We aim to give back freedom to as many orangutans as we can and one of the orangutans we reintroduce during this event has made an incredible journey; Wanna was illegally smuggled out of Indonesia to Thailand as a baby, then repatriated to Indonesia in 2006, together with another 47 illegally exported orangutans. These orangutans have been progressing through our rehabilitation program for 11 years. Wanna is now 17 and finally ready to be returned to natural habitat and freedom....read more
