Improving the welfare of captive nonhuman primates requires evaluating the stressors created by the captive environment and reducing their negative effects. Social separation, although sometimes necessary for managing the genetic diversity of captive populations of animals, causes both psychological and physiological stress in human and primate monkey infants. Few studies have examined the maternal response of great ape mothers to separation from their offspring. This article describes the behavioral changes of a mother orangutan (Pongo pygmaeus abelii) after separation from her juvenile daughter. We collected data on measures of proximity and social behavior before the separation of the mother-infant dyad and of locomotion, arboreality, abnormal behavior, solitary behavior, and vocalization both before and after separation. We observed no behavioral indications of protest but observed some indications of despair after separation: decreased locomotion, increased inactivity, and increased self-directed behavior. In addition, we observed increases in arboreality and object-oriented behavior during morning sessions. These findings suggest that mother-juvenile separation in orangutans might be less stressful for mothers than might be expected. Such research has implications for the welfare and management of captive animals.
