The paper shows orangutan mothers adjust their ranging behavior to increase offspring social play, at an energetic cost.

The paper analyzes social and individual learning in wild orangutans over eight years, finding that social learning is more frequent and synergistically shapes diet profiles with individual learning.

After controlling for confounders, 15 wild Sumatran orangutan mothers differed consistently in average expression of four of six maternal behaviours and in age-related plasticity for three.

This study examines how socioecological factors and mother-offspring characteristics influence maternal behaviors in wild Sumatran orangutans.
