As research conducted by students from Tanjungpura University, Pontianak, continues on several orangutan individuals, the animal keepers, together with the behavior and medical teams, have implemented a number of temporary adjustments to orangutan groupings. These adjustments are intended to support the smooth implementation of the research activities while continuing to prioritize animal welfare and the natural behavioral needs of each individual.

Under the latest grouping arrangement, Redi—who was previously housed in the same group as Otan and Seko—has now joined Banir and Julia. Despite the change in group composition, Redi continues to show a dominant character and remains the most prominent individual in the group’s social dynamics. His role is clearly evident in daily interactions, both during shared activities and in situations involving access to resources.

To anticipate potential food competition that often arises in groups with a dominant individual, the keeper team has implemented an adaptive feeding management strategy. During feeding sessions, individuals within the group are alternately separated into tunnel areas. This method allows each orangutan to receive an appropriate food portion according to their needs, while also minimizing the risk of conflict and stress. This approach is also used as part of ongoing monitoring of Redi’s social behavior within his new group context.

Amid the seasonal transition from the rainy season to the dry season, Redi’s health condition has remained stable and good. He demonstrates consistent activity levels, a healthy appetite, and normal responses to environmental changes. His ability to adapt to changing weather conditions indicates that he remains strong and well-maintained.

Redi’s behavioral development has become increasingly evident since he no longer stays overnight in the enclosure during the forest school period. Based on observations by the monitoring team, Redi is now able to build his own nest in the forest for resting. In contrast to his close companion, Seko—who still often builds nests close to or together with other individuals—Redi consistently chooses to construct his nest independently. The ability to select an appropriate location, gather materials, and build a nest independently is an essential skill for orangutans in the wild. Therefore, this behavior is considered a very positive progression and represents a key indicator of Redi’s increasing independence within his ongoing rehabilitation process.
