During the past month, we continued to follow Monic, Astrid and Tarzan (orangutans from the first release) as well as Ika, Heldy, Mama Tata, Tata and Komeng (all from the second release) and also Ebol and Mama Ebol (from the third release). All orangutans are doing very well, eating more and more.
This month the most popular foods were termites and rambutan fruits. Females like Ika, Monic or Ebol spent most of the time looking for and eating termites whilst Tarzan prefered rambutan.
He would not leave a tree if there were still fruits left on it and in the cases when he didn’t have enough time to eat all the fruits in one day, he would make a nest in the nearest tree and start his next day by finishing what was left before moving on to another rambutan tree.Some of the followed individuals: Mama Ebol, Mama Tata, Komeng and Tata still do not like us observing them. We thus only observe them for a short period of time to make sure they are in good health, then we move away to ensure we minimise stress. It is a very good sign that released orangutans are afraid of people and do not feel comfortable near us. As part of our scheduled daily activities we also looked for orangutans using our radio-tracking equipment. We have been able to pick up, among others, signals of Tantri, Maradona, Sumbing, Jessica and Onceng. The last four orangutans were released in Batikap in August and already moved away from the release site. All signals were picked up from Bukit Simon which is, so far, our best radio-tracking spot. But the fact we recorded these individuals from this particular location means that they traveled south-west from release site towards our camp. Nonetheless they are still far enough so we can not directly observe them when checking our transects (within 3 km distance from camp).
In October we will continue to observe all orangutans we follow each month and carry on radio-tracking. We will be also preparing for a next release scheduled for the beginning of November. So the monitoring team will definitely be busy in the coming weeks and we will keep you updated on what is going on back in Camp Posu.
