Our new paper is out! 🥳
We found evidence that migrant orangutan males in Suaq Balimbing, Sumatra, and in Tuanan, Borneo, use observational social learning (also called “peering” behavior) to learn new ecological knowledge from local individuals after dispersing to a new area.
We thank all collaborators that made this study possible, which we published in Frontiers in Ecology and Evolution.
Here a migrant orangutan male (on the right side) is peering at an adult local female, feeding on termites within a dead branch.
